+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH. The drawback is that using absolute paths prevent a
+# configured tree to be moved without reconfiguration.

+\`configure' configures dvipng (TeX Live) 1.17 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
+ --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]

+ --with-gnu-ld assume the C compiler uses GNU ld [default=no]
+ --with-sysroot[=DIR] Search for dependent libraries within DIR (or the
+ compiler's sysroot if not specified).
+ --with-gs=/PATH/TO/gs Hard-wire the location of GhostScript
+ --with-system-kpathsea use installed kpathsea headers and library (requires
+ pkg-config)
+ --with-system-zlib use installed zlib headers and library
+ --with-zlib-includes=DIR
+ zlib headers installed in DIR
+ --with-zlib-libdir=DIR zlib library installed in DIR

+ (requires freetype-config)
+ --with-system-gd use installed gd headers and library
+ --with-gd-includes=DIR gd headers installed in DIR
+ --with-gd-libdir=DIR gd library installed in DIR
+
+Some influential environment variables:
+ CC C compiler command
+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+ you have headers in a nonstandard directory <include dir>
+ LT_SYS_LIBRARY_PATH
+ User-defined run-time library search path.
+ CPP C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+ like early versions of FreeBSD and possibly contemporary NetBSD.)
+ For shared mappings, we should conversely verify that changes get
+ propagated back to all the places they're supposed to be.
+
+ Grep wants private fixed already mapped.
+ The main things grep needs to know about mmap are:

+dvipng [options] [filename] \-
+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+This program makes \s-1PNG\s0 and/or \s-1GIF\s0 graphics from \s-1DVI\s0 files as obtained
+from TeX and its relatives.
+.PP
+If \s-1GIF\s0 support is enabled, \s-1GIF\s0 output is chosen by using the
+\&\fBdvigif\fR binary or with the \fB\-\-gif\fR option.
+.PP
+The benefits of \fBdvipng\fR/\fBdvigif\fR include
+.IP "*" 4
+Speed. It is a very fast bitmap-rendering code for \s-1DVI\s0 files, which
+makes it suitable for generating large amounts of images on-the-fly,
+as needed in preview-latex, WeBWorK and others.
+.IP "*" 4
+It does not read the postamble, so it can be started before TeX
+finishes. There is a \fB\-\-follow\fR switch that makes dvipng wait at
+end-of-file for further output, unless it finds the \s-1POST\s0 marker that
+indicates the end of the \s-1DVI.\s0
+.IP "*" 4
+Interactive query of options. dvipng can read options interactively
+through stdin, and all options are usable. It is even possible to change
+the input file through this interface.
+.IP "*" 4
+Supports \s-1PK, VF,\s0 PostScript Type1, and TrueType fonts, subfonts (i.e.,
+as used in CJK-LaTeX), color specials, and inclusion of PostScript,
+\&\s-1PNG, JPEG\s0 or \s-1GIF\s0 images.
+.IP "*" 4
+and more...
+.SH "OPTIONS"
+.IX Header "OPTIONS"
+Many of the parameterless options listed here can be turned off by
+suffixing the option with a zero (\fB0\fR); for instance, to turn off
+page reversal, use \fB\-r0\fR. Such options are marked with a trailing
+\&\fB*\fR.
+.IP "\fB\-\fR" 4
+.IX Item "-"
+Read additional options from standard input after processing the command
+line.
+.IP "\fB\-\-help\fR" 4
+.IX Item "--help"
+Print a usage message and exit.
+.IP "\fB\-\-version\fR" 4
+.IX Item "--version"
+Print the version number and exit.
+.IP "\fB\-bd\fR \fInum\fR" 4
+.IX Item "-bd num"
+.PD 0
+.IP "\fB\-bd\fR \fIcolor_spec\fR" 4
+.IX Item "-bd color_spec"
+.IP "\fB\-bd '\fR\fInum\fR\fB \fR\fIcolor_spec\fR\fB'\fR" 4
+.IX Item "-bd 'num color_spec'"
+.PD
+Set the pixel width of the transparent border (default 0). Using this
+option will make the image edges transparent, but it only affects pixels
+with the background color. Giving a \fIcolor_spec\fR will set the
+fallback color, to be used in viewers that cannot handle transparency
+(the default is the background color). The color spec should be in
+TeX color \especial syntax, e.g., 'rgb 1.0 0.0 0.0'. Setting the
+fallback color makes the default border width 1 px.
+.IP "\fB\-\-bdpi\fR \fInum\fR" 4
+.IX Item "--bdpi num"
+This option only has an effect when using bitmapped (\s-1PK\s0) fonts. The
+option sets the base (Metafont) resolution, both horizontal and
+vertical, to \fInum\fR dpi (dots per inch). This option is necessary
+when manually selecting Metafont mode with the \-\-mode option (see
+below).
+.IP "\fB\-bg\fR \fIcolor_spec\fR" 4
+.IX Item "-bg color_spec"
+Choose background color for the images. This option will be ignored if
+there is a background color \especial in the \s-1DVI.\s0 The color spec should
+be in TeX color \especial syntax, e.g., 'rgb 1.0 0.0 0.0'. You can
+also specify 'Transparent' or 'transparent' which will give you a
+transparent background with the normal background as a fallback color. A
+capitalized 'Transparent' will give a full-alpha transparency, while an
+all-lowercase 'transparent' will give a simple fully transparent
+background with non-transparent antialiased pixels. The latter would be
+suitable for viewers who cannot cope with a true alpha channel. \s-1GIF\s0
+images do not support full alpha transparency, so in case of \s-1GIF\s0 output,
+both variants will use the latter behaviour.
+.IP "\fB\-d\fR \fInum\fR" 4
+.IX Item "-d num"
+Set the debug flags, showing what dvipng (thinks it) is doing. This will
+work unless dvipng has been compiled without the \f(CW\*(C`DEBUG\*(C'\fR option
+(not recommended). Set the flags as you need them, use \fB\-d \-1\fR as
+the first option for maximum output.
+.IP "\fB\-D\fR \fInum\fR" 4
+.IX Item "-D num"
+Set the output resolution, both horizontal and vertical, to \fInum\fR
+dpi (dots per inch).
+.Sp
+One may want to adjust this to fit a certain text font size (e.g., on
+a web page), and for a text font height of \fIfont_px\fR pixels (in
+Mozilla) the correct formula is
+.Sp
+.Vb 1
+\& <dpi> = <font_px> * 72.27 / 10 [px * TeXpt/in / TeXpt]
+.Ve
+.Sp
+The last division by ten is due to the standard font height 10pt in
+your document, if you use 12pt, divide by 12. Unfortunately, some
+proprietary browsers have font height in pt (points), not pixels. You
+have to rescale that to pixels, using the screen resolution (default
+is usually 96 dpi) which means the formula is
+.Sp
+.Vb 1
+\& <font_px> = <font_pt> * 96 / 72 [pt * px/in / (pt/in)]
+.Ve
+.Sp
+On some high-res screens, the value is instead 120 dpi. Good luck!
+.IP "\fB\-\-depth*\fR" 4
+.IX Item "--depth*"
+Report the depth of the image. This only works reliably when the
+LaTeX style \fIpreview.sty\fR from preview-latex is used with
+the \fBactive\fR option. It reports the number of pixels from the
+bottom of the image to the baseline of the image. This can be used for
+vertical positioning of the image in, e.g., web documents, where one
+would use (Cascading StyleSheets 1)

+The depth is a negative offset in this case, so the minus sign is
+necessary, and the unit is pixels (px).
+.IP "\fB\-\-dvinum*\fR" 4
+.IX Item "--dvinum*"
+Set this option to make the output page number be the TeX page
+numbers rather than the physical page number. See the \fB\-o\fR switch.
+.IP "\fB\-fg\fR \fIcolor_spec\fR" 4
+.IX Item "-fg color_spec"
+Choose foreground color for the images. This option will be ignored if
+there is a foreground color \especial in the \s-1DVI.\s0 The color spec should
+be in TeX color \especial syntax, e.g., 'rgb 1.0 0.0 0.0'.
+.IP "\fB\-\-follow*\fR" 4
+.IX Item "--follow*"
+Wait for data at end-of-file. One of the benefits of dvipng is that it
+does not read the postamble, so it can be started before TeX
+finishes. This switch makes dvipng wait at end-of-file for further
+output, unless it finds the \s-1POST\s0 marker that indicates the end of the
+\&\s-1DVI.\s0 This is similar to \fBtail \-f\fR but for DVI-to-PNG conversion.
+.IP "\fB\-\-freetype*\fR" 4
+.IX Item "--freetype*"
+Enable/disable FreeType font rendering (default on). This option is
+available if the FreeType2 font library was present at compilation time.
+If this is the case, dvipng will have direct support for PostScript
+Type1 and TrueType fonts internally, rather than using \fBgsftopk\fR
+for rendering the fonts. If you have PostScript versions of Computer
+Modern installed, there will be no need to generate bitmapped (\s-1PK\s0)
+variants on disk of these. Then, you can render images at different (and
+unusual) resolutions without cluttering the disk with lots of bitmapped
+fonts.
+One reason to disable FreeType font rendering would be to generate
+identical output on different platforms, since FreeType uses the native
+renderer and therefore can give slightly different output on each platform.
+.IP "\fB\-\-gamma\fR \fInum\fR" 4
+.IX Item "--gamma num"
+Control the interpolation of colors in the greyscale anti-aliasing
+color palette. Default value is 1.0. For 0 < \fInum\fR < 1, the
+fonts will be lighter (more like the background), and for \fInum\fR >
+1, the fonts will be darker (more like the foreground).
+.IP "\fB\-\-gif*\fR" 4
+.IX Item "--gif*"
+The images are output in the \s-1GIF\s0 format, if \s-1GIF\s0 support is enabled.
+This is the default for the \fBdvigif\fR binary, which only will be
+available when \s-1GIF\s0 support is enabled. \s-1GIF\s0 images are palette images
+(see the \fB\-\-palette\fR option) and does not support true alpha
+channels (see the \fB\-\-bg\fR option). See also the \fB\-\-png\fR
+option.
+.IP "\fB\-\-height*\fR" 4
+.IX Item "--height*"
+Report the height of the image. This only works reliably when the
+LaTeX style \fIpreview.sty\fR from preview-latex is used with
+the \fBactive\fR option. It reports the number of pixels from the top
+of the image to the baseline of the image. The total height of the
+image is obtained as the sum of the values reported from
+\&\fB\-\-height\fR and \fB\-\-depth\fR.
+.IP "\fB\-l [=]\fR\fInum\fR" 4
+.IX Item "-l [=]num"
+The last page printed will be the first one numbered \fInum\fR. Default
+is the last page in the document. If \fInum\fR is prefixed by an equals
+sign, then it (and the argument to the \fB\-p\fR option, if specified)
+is treated as a physical (absolute) page number, rather than a value to
+compare with the TeX \fB\ecount0\fR values stored in the \s-1DVI\s0 file.
+Thus, using \fB\-l =9\fR will end with the ninth page of the document,
+no matter what the pages are actually numbered.
+.IP "\fB\-\-mode\fR \fImode\fR" 4
+.IX Item "--mode mode"
+This option only has an effect when using bitmapped (\s-1PK\s0) fonts. Use
+\&\fImode\fR as the Metafont device name for the \s-1PK\s0 fonts (both for path
+searching and font generation). This needs to be augmented with the base
+device resolution, given with the \fB\-\-bdpi\fR option. See the file
+<\fBftp://ftp.tug.org/tex/modes.mf\fR> for a list of resolutions and mode
+names for most devices.
+.IP "\fB\-M*\fR" 4
+.IX Item "-M*"
+This option only has an effect when using bitmapped (\s-1PK\s0) fonts. It turns
+off automatic \s-1PK\s0 font generation (\fImktexpk\fR).
+.IP "\fB\-\-nogs*\fR" 4
+.IX Item "--nogs*"
+This switch prohibits the internal call to GhostScript for displaying
+PostScript specials. \fB\-\-nogs0\fR turns the call back on.
+.IP "\fB\-\-nogssafer*\fR" 4
+.IX Item "--nogssafer*"
+Normally, if GhostScript is used to render PostScript specials, the
+GhostScript interpreter is run with the option \fB\-dSAFER\fR. The
+\&\fB\-\-nogssafer\fR option runs GhostScript without \fB\-dSAFER\fR. The
+\&\fB\-dSAFER\fR option in Ghostscript disables PostScript operators such
+as deletefile, to prevent possibly malicious PostScript programs from
+having any effect.
+.IP "\fB\-\-norawps*\fR" 4
+.IX Item "--norawps*"
+Some packages generate raw PostScript specials, even non-rendering such
+specials. This switch turns off the internal call to GhostScript
+intended to display these raw PostScript specials. \fB\-\-norawps0\fR
+turns the call back on.
+.IP "\fB\-o\fR \fIname\fR" 4
+.IX Item "-o name"
+Send output to the file \fIname\fR. A single occurrence of \fB\f(CB%d\fB\fR or
+\&\fB\f(CB%01d\fB\fR, ..., \fB\f(CB%09d\fB\fR will be exchanged for the physical
+page number (this can be changed, see the \fB\-\-dvinum\fR switch). The
+default output filename is \fIfile\fR\fB\f(CB%d\fB.png\fR where the input \s-1DVI\s0
+file was \fIfile\fR\fB.dvi\fR.
+.IP "\fB\-O\fR \fIx\-offset\fR\fB,\fR\fIy\-offset\fR" 4
+.IX Item "-O x-offset,y-offset"
+Move the origin by \fIx\-offset\fR,\fIy\-offset\fR, a comma-separated
+pair of dimensions such as \fB.1in,\-.3cm\fR.
+The origin of the page is shifted from the default position
+(of one inch down, one inch to the right from the upper left corner of
+the paper) by this amount.
+.IP "\fB\-p [=]\fR\fInum\fR" 4
+.IX Item "-p [=]num"
+The first page printed will be the first one numbered \fInum\fR. Default
+is the first page in the document. If \fInum\fR is prefixed by an
+equals sign, then it (and the argument to the \fB\-l\fR option, if
+specified) is treated as a physical (absolute) page number, rather than
+a value to compare with the TeX \fB\ecount0\fR values stored in the
+\&\s-1DVI\s0 file. Thus, using \fB\-p =3\fR will start with the third page of
+the document, no matter what the pages are actually numbered.
+.IP "\fB\-\-palette*\fR" 4
+.IX Item "--palette*"
+When an external image is included, \fBdvipng\fR will automatically
+switch to truecolor mode, to avoid unnecessary delay and quality
+reduction, and enable the \s-1EPS\s0 translator to draw on a transparent
+background and outside of the boundingbox. This switch will force
+palette (256\-color) output and make \fBdvipng\fR revert to opaque
+clipped image inclusion. This will also override the \fB\-\-truecolor\fR
+switch if present.
+.IP "\fB\-\-picky*\fR" 4
+.IX Item "--picky*"
+No images are output when a warning occurs. Normally, dvipng will
+output an image in spite of a warning, but there may be something
+missing in this image. One reason to use this option would be if you
+have a more complete but slower fallback converter. Mainly, this is
+useful for failed figure inclusion and unknown \especial occurrences,
+but warnings will also occur for missing or unknown color specs and
+missing \s-1PK\s0 fonts.
+.IP "\fB\-\-png*\fR" 4
+.IX Item "--png*"
+The images are output in the \s-1PNG\s0 format. This is the default for the
+\&\fBdvipng\fR binary. See also the \fB\-\-gif\fR option.
+.IP "\fB\-pp\fR \fIfirstpage\fR\fB\-\fR\fIlastpage\fR" 4
+.IX Item "-pp firstpage-lastpage"
+Print pages \fIfirstpage\fR through \fIlastpage\fR; but not quite
+equivalent to \fB\-p\fR \fIfirstpage\fR \fB\-l\fR \fIlastpage\fR. For example,
+when rendering a book, there may be several instances of a page in the
+\&\s-1DVI\s0 file (one in \f(CW\*(C`\efrontmatter\*(C'\fR, one in \f(CW\*(C`\emainmatter\*(C'\fR, and one
+in \f(CW\*(C`\ebackmatter\*(C'\fR). In case of several pages matching, \fB\-pp\fR
+\&\fIfirstpage\fR\fB\-\fR\fIlastpage\fR will render \fIall\fR pages that
+matches the specified range, while \fB\-p\fR \fIfirstpage\fR \fB\-l\fR
+\&\fIlastpage\fR will render the pages from the \fIfirst\fR occurrence
+of \fIfirstpage\fR to the \fIfirst\fR occurrence of \fIlastpage\fR.
+This is the (undocumented) behaviour of dvips. In dvipng you can give
+both kinds of options, in which case you get all pages that matches the
+range in \fB\-pp\fR between the pages from \fB\-p\fR to \fB\-l\fR. Also
+multiple \fB\-pp\fR options accumulate, unlike \fB\-p\fR and \fB\-l\fR.
+The \fB\-\fR separator can also be \fB:\fR. Note that \fB\-pp \-1\fR
+will be interpreted as \*(L"all pages up to and including 1\*(R", if you want a
+page numbered \-1 (only the table of contents, say) put \fB\-pp \-1\-\-1\fR,
+or more readable, \fB\-pp \-1:\-1\fR.
+.IP "\fB\-q*\fR" 4
+.IX Item "-q*"
+Run quietly. Don't chatter about pages converted, etc. to standard
+output; report no warnings (only errors) to standard error.
+.IP "\fB\-Q\fR \fInum\fR" 4
+.IX Item "-Q num"
+Set the quality to \fInum\fR. That is, choose the number of antialiasing
+levels for bitmapped fonts (\s-1PK\s0), to be
+\&\fInum\fR*\fInum\fR+1. The default value is 4 which gives 17 levels of
+antialiasing for antialiased fonts from these two. If FreeType is
+available, its rendering is unaffected by this option.
+.IP "\fB\-r*\fR" 4
+.IX Item "-r*"
+Toggle output of pages in reverse/forward order. By default, the first
+page in the \s-1DVI\s0 is output first.
+.IP "\fB\-\-strict*\fR" 4
+.IX Item "--strict*"
+The program exits when a warning occurs. Normally, dvipng will output
+an image in spite of a warning, but there may be something missing in
+this image. One reason to use this option would be if you have a more
+complete but slower fallback converter. See the \fB\-\-picky\fR option
+above for a list of when warnings occur.
+.IP "\fB\-T\fR \fIimage_size\fR" 4
+.IX Item "-T image_size"
+Set the image size to \fIimage_size\fR which can be either of
+\&\fBbbox\fR, \fBtight\fR, or a comma-separated pair of dimensions
+\&\fIhsize\fR,\fIvsize\fR such as \fB.1in,.3cm\fR. The default is
+\&\fBbbox\fR which produces a \s-1PNG\s0 that includes all ink put on the page
+and in addition the \s-1DVI\s0 origin, located 1in from the top and 1in from
+the left edge of the paper. This usually gives whitespace above and to
+the left in the produced image. The value \fBtight\fR will make dvipng
+only include all ink put on the page, producing neat images.
+.IP "\fB\-\-truecolor*\fR" 4
+.IX Item "--truecolor*"
+This will make \fBdvipng\fR generate truecolor output. Note that
+truecolor output is automatic if you include an external image in your
+\&\s-1DVI,\s0 e.g., via a PostScript special (i.e., the \fBgraphics\fR or
+\&\fBgraphicx\fR package). This switch is overridden by the
+\&\fB\-\-palette\fR switch.
+.IP "\fB\-v*\fR" 4
+.IX Item "-v*"
+Enable verbose operation. This will currently indicate what fonts is
+used, in addition to the usual output.
+.IP "\fB\-\-width*\fR" 4
+.IX Item "--width*"
+Report the width of the image. See also \fB\-\-height\fR and
+\&\fB\-\-depth\fR.
+.IP "\fB\-x\fR \fInum\fR" 4
+.IX Item "-x num"
+This option is deprecated; it should not be used. It is much better to
+select the output resolution directly with the \fB\-D\fR option. This
+option sets the magnification ratio to \fInum\fR/1000 and
+overrides the magnification specified in the \s-1DVI\s0 file. Must be between
+10 and 100000. It is recommended that you use standard magstep values
+(1095, 1200, 1440, 1728, 2074, 2488, 2986, and so on) to help reduce the
+total number of \s-1PK\s0 files generated. \fInum\fR may be a real number, not
+an integer, for increased precision.
+.IP "\fB\-z\fR \fInum\fR" 4
+.IX Item "-z num"
+Set the \s-1PNG\s0 compression level to \fInum\fR. This option is enabled if
+your \fBlibgd\fR is new enough. The default compression level is 1,
+which selects maximum speed at the price of slightly larger PNGs. For an
+older \fBlibgd\fR, the hard-soldered value 5 is used. The include file
+\&\fBpng.h\fR says
+\&\*(L"Currently, valid values range from 0 \- 9, corresponding directly to
+the zlib compression levels 0 \- 9 (0 \- no compression, 9 \- \*(R"maximal\*(L"
+compression). Note that tests have shown that zlib compression levels
+3\-6 usually perform as well as level 9 for \s-1PNG\s0 images, and do
+considerably fewer calculations. In the future, these values may not
+correspond directly to the zlib compression levels.\*(R"

+
+1 Introduction
+**************
+
+This program makes PNG and/or GIF graphics from DVI files as obtained
+from TeX and its relatives.
+
+ If GIF support is enabled, GIF output is chosen by using the 'dvigif'
+binary or with the '--gif' option.
+
+ It is intended to produce anti-aliased screen-resolution images as
+fast as is possible. The target audience is people who need to generate
+and regenerate many images again and again. The primary target is the
+preview-latex (X)Emacs package, a package to preview formulas from
+within (X)Emacs. Yes, you get to see your formulas in the (X)Emacs
+buffer, see <http://www.gnu.org/software/auctex/preview-latex.html>.
+
+ Another example is WeBWorK, an internet-based method for delivering
+homework problems to students over the internet, giving students instant
+feedback as to whether or not their answers are correct, see
+<http://webwork.math.rochester.edu>.
+
+ A more recent addition to the dvipng-using applications out there is
+MediaWiki, the software behind Wikipedia and many other wikis out there.
+Dvipng is used to render mathematical formulae from version 1.8.0 of
+MediaWiki, see <http://www.mediawiki.org>.
+
+ Other applications may also benefit, like web applications as
+latex2html and WYSIWYG editors like LyX.
+
+ The benefits of 'dvipng'/'dvigif' include
+
+ * Speed. It is a very fast bitmap-rendering code for DVI files,
+ which makes it suitable for generating large amounts of images
+ on-the-fly, as needed in preview-latex, WeBWorK and others.
+
+ * It does not read the postamble, so it can be started before TeX
+ finishes. There is a '--follow' switch that makes dvipng wait at
+ end-of-file for further output, unless it finds the POST marker
+ that indicates the end of the DVI.
+
+ * Interactive query of options. dvipng can read options
+ interactively through stdin, and all options are usable. It is
+ even possible to change the input file through this interface.
+
+ * Supports PK, VF, PostScript Type1, and TrueType fonts, subfonts
+ (i.e., as used in CJK-LaTeX), color specials, and inclusion of
+ PostScript, PNG, JPEG or GIF images.
+
+ * and more...

+2 Installation
+**************
+
+Installing dvipng should be simple: merely './configure', 'make', and
+'make install'.

+* Installation outside the texmf tree::

+
+File: dvipng.info, Node: Prerequisites, Next: Configure, Up: Installation
+
+2.1 Prerequisites
+=================
+
+ * The GD Graphics Draw library, libgd
+
+ The drawing library 'libgd' is necessary, and is downloadable at
+ <https://bitbucket.org/libgd/gd-libgd/downloads>, and there are
+ binary packages for most operating systems from their respective
+ distributors. In any case, the library installs using 'autoconf'
+ so it should not be difficult for you to install it from source,
+ and then proceed with installing dvipng.
+
+ * The path-searching library kpathsea
+
+ Kpathsea is most likely included in your LaTeX installation, but it
+ may happen that ./configure does not find it; see below. If you do
+ not have it, download it from <http://www.ctan.org> and compile it.
+ I have no experience with this, so I cannot help much here.
+
+ * The font-rendering library FreeType 2
+
+ While not strictly necessary, a recent FreeType 2 is recommended
+ since dvipng currently will produce better-quality images when this
+ library is available. To take advantage of this, you should have
+ at least FreeType 2.1.9.
+
+ FreeType 2 will enable direct support for PostScript and TrueType
+ fonts, so that dvipng will not need to generate bitmapped variants
+ on disk of the TeX fonts since modern TeX distributions include
+ PostScript versions of them. Then, you can render images at
+ different (and unusual) resolutions without cluttering the disk
+ with lots of bitmapped fonts.
+
+ Finally, it will enable subfont support in dvipng. That is, if you
+ want to render CJK-LaTeX characters, you must have FreeType 2
+ installed.
+
+ * libpng and libz
+
+ To be able to compress and write PNG files to disk, dvipng (or
+ really libgd) uses libpng which in turn uses libz. These should be
+ available on any modern system, if not, download them and install
+ them.
+
+ * The 'texinfo' package
+
+ This is needed for building the documentation.
+
+
+File: dvipng.info, Node: Configure, Next: Build/install, Prev: Prerequisites, Up: Installation
+
+2.2 Configure
+=============
+
+The first step is to configure the source code, telling it where various
+files will be. To do so, run
+
+ ./configure OPTIONS
+
+ (Note: if you have fetched dvipng from CVS rather than a regular
+release, you will have to first generate './configure' by running
+'autoconf' 2.53 or later.)
+
+ On many machines, you will not need to specify any options, but if
+'configure' cannot determine something on its own, you'll need to help
+it out. For a list of the options type
+
+ ./configure --help
+
+ On some machines, the libraries will be installed in directories that
+are not in the linker's search path. This will generate an error when
+running './configure', indicating that it cannot find libgd or
+libkpathsea (most likely). You then need to specify the path to the
+respective library's object files. They are typically called e.g.,
+'libgd.a' or 'libgd.so'. If they are located in e.g., '/sw/local/lib',
+do
+
+ ./configure LDFLAGS=-L/sw/local/lib
+
+ If the library is available as a shared object file ('.so'), the
+runtime linker may also need to be told where to find the library, then
+use
+
+ ./configure LDFLAGS='-L/sw/local/lib -R/sw/local/lib'
+
+ When either of these is necessary, it is likely that the C header
+files are also installed in directories that are not in the C
+preprocessor's search path. This will also generate an error when
+running './configure', indicating that it cannot find e.g., 'gd.h' or
+'kpathsea.h' (most likely). You then need to specify the path to the
+respective library's C header files. If they are located in e.g.,
+'/sw/local/include', do
+
+ ./configure CPPFLAGS=-I/sw/local/include
+
+ On my SUN Solaris workstation, I had to combine this into
+
+ ./configure CPPFLAGS='-I/sw/local/include -I/sw/tex/teTeX/1.0/include'\
+ LDFLAGS='-L/sw/local/lib -R/sw/local/lib -L/sw/tex/teTeX/1.0/lib/'
+
+where the backslash denotes a continuation of the line.
+
+
+File: dvipng.info, Node: Build/install, Next: Installation outside the texmf tree, Prev: Configure, Up: Installation
+
+2.3 Build/install
+=================
+
+Once 'configure' has been run, simply enter
+
+ make
+
+at the prompt to compile the C code, and build the documentation files.
+To install the files into the locations chosen earlier, type
+
+ make install
+
+You may need special privileges to install, e.g., if you are installing
+into system directories.
+
+
+File: dvipng.info, Node: Installation outside the texmf tree, Next: Advice for non-privileged users, Prev: Build/install, Up: Installation
+
+2.4 Installation outside the texmf tree
+=======================================
+
+In some cases, a dvipng binary installed outside the texmf tree will not
+be able to find virtual fonts, or the PostScript font maps (normally
+used by dvips). This may be because _only_ $SELFAUTOLOC, $SELFAUTODIR,
+and $SELFAUTOPARENT are used in the texmf tree configuration file
+'texmf.cnf'. If so, give the switch '--enable-selfauto-set' to
+'./configure'. This will make dvipng adjust these three internally so
+that kpathsea thinks that dvipng _is_ installed in the texmf tree.
+
+
+File: dvipng.info, Node: Advice for non-privileged users, Prev: Installation outside the texmf tree, Up: Installation
+
+2.5 Installation for non-privileged users
+=========================================
+
+Often people without system administration privileges want to install
+software for their private use. In that case you need to specify more
+options to the 'configure' script, usually this is done by using the
+'--prefix' option to the 'configure' script, and let it point to the
+personal home directory. In that way, resulting binaries will be
+installed under the 'bin' subdirectory of your home directory, manual
+pages under 'man' and so on. That way, it is reasonably easy to
+maintain a bunch of additional packages, since the prefix argument is
+supported by most 'configure' scripts.
+
+ You'll have to add something like '/home/myself/bin' to your 'PATH'
+shell variable, if it isn't there already, and similarly set the
+'INFOPATH' and 'MANPATH' variables to be able to access the
+documentation.

+3 Basic usage of dvipng
+***********************
+
+To use dvipng at its simplest, simply type
+
+ dvipng foo
+
+where 'foo.dvi' is the output of TeX that you want to convert to PNG
+format. If there are four pages in 'foo.dvi', those pages will be
+output as 'foo1.png', 'foo2.png', 'foo3.png', and 'foo4.png',
+respectively.
+
+ If you have enabled the PostScript font support (via FreeType), fonts
+will be rendered as they are needed. Otherwise, dvipng will use
+bitmapped (PK) fonts, and if you use PK fonts that have not been used on
+your system before, they may be automatically generated; this process
+can take a few minutes, so progress reports appear by default. The next
+time the same font is used, it will have been saved on disk, so
+rendering will go much faster. (If dvipng tries to endlessly generate
+the same fonts over and over again, something is wrong. *Note
+(kpathsea)Unable to generate fonts::.)
+
+ Many options are available (see the next section). For a brief
+summary of available options, just type
+
+ dvipng --help

+
+4.2 Option details
+==================
+
+Many of the parameterless options listed here can be turned off by
+suffixing the option with a zero ('0'); for instance, to turn off page
+reversal, use '-r0'. Such options are marked with a trailing '*'.
+
+'-'
+ Read additional options from standard input after processing the
+ command line.
+
+'--help'
+ Print a usage message and exit.
+
+'--version'
+ Print the version number and exit.
+
+'-bd NUM'
+'-bd COLOR_SPEC'
+'-bd 'NUM COLOR_SPEC''
+ Set the pixel width of the transparent border (default 0). Using
+ this option will make the image edges transparent, but it only
+ affects pixels with the background color. Giving a COLOR_SPEC will
+ set the fallback color, to be used in viewers that cannot handle
+ transparency (the default is the background color). The color spec
+ should be in TeX color \special syntax, e.g., 'rgb 1.0 0.0 0.0'.
+ Setting the fallback color makes the default border width 1 px.
+ *Note Color::.
+
+'--bdpi NUM'
+ This option only has an effect when using bitmapped (PK) fonts.
+ The option sets the base (Metafont) resolution, both horizontal and
+ vertical, to NUM dpi (dots per inch). This option is necessary
+ when manually selecting Metafont mode with the -mode option (see
+ below).
+
+'-bg COLOR_SPEC'
+ Choose background color for the images. This option will be
+ ignored if there is a background color \special in the DVI. The
+ color spec should be in TeX color \special syntax, e.g., 'rgb 1.0
+ 0.0 0.0'. You can also specify 'Transparent' or 'transparent'
+ which will give you a transparent background with the normal
+ background as a fallback color. A capitalized 'Transparent' will
+ give a full-alpha transparency, while an all-lowercase
+ 'transparent' will give a simple fully transparent background with
+ non-transparent antialiased pixels. The latter would be suitable
+ for viewers who cannot cope with a true alpha channel. GIF images
+ do not support full alpha transparency, so in case of GIF output,
+ both variants will use the latter behaviour. *Note Color::.
+
+'-d NUM'
+ Set the debug flags, showing what dvipng (thinks it) is doing.
+ This will work unless dvipng has been compiled without the 'DEBUG'
+ option (not recommended). Set the flags as you need them, use '-d
+ -1' as the first option for maximum output. *Note Debug options::.
+
+'-D NUM'
+ Set the output resolution, both horizontal and vertical, to NUM dpi
+ (dots per inch).
+
+ One may want to adjust this to fit a certain text font size (e.g.,
+ on a web page), and for a text font height of FONT_PX pixels (in
+ Mozilla) the correct formula is
+ DPI = FONT_PX * 72.27 / 10 [px * TeXpt/in / TeXpt]
+ The last division by ten is due to the standard font height 10pt in
+ your document, if you use 12pt, divide by 12. Unfortunately, some
+ proprietary browsers have font height in pt (points), not pixels.
+ You have to rescale that to pixels, using the screen resolution
+ (default is usually 96 dpi) which means the formula is
+ FONT_PX = FONT_PT * 96 / 72 [pt * px/in / (pt/in)]
+ On some high-res screens, the value is instead 120 dpi. Good luck!
+
+'--depth*'
+ Report the depth of the image. This only works reliably when the
+ LaTeX style 'preview.sty' from preview-latex is used with the
+ 'active' option. It reports the number of pixels from the bottom
+ of the image to the baseline of the image. This can be used for
+ vertical positioning of the image in, e.g., web documents, where
+ one would use (Cascading StyleSheets 1)
+ <IMG SRC="FILENAME.PNG" STYLE="vertical-align: -DEPTHpx">
+ The depth is a negative offset in this case, so the minus sign is
+ necessary, and the unit is pixels (px).
+
+'--dvinum*'
+ Set this option to make the output page number be the TeX page
+ numbers rather than the physical page number. See the '-o' switch.
+
+'-fg COLOR_SPEC'
+ Choose foreground color for the images. This option will be
+ ignored if there is a foreground color \special in the DVI. The
+ color spec should be in TeX color \special syntax, e.g., 'rgb 1.0
+ 0.0 0.0'. *Note Color::.
+
+'--follow*'
+ Wait for data at end-of-file. One of the benefits of dvipng is
+ that it does not read the postamble, so it can be started before
+ TeX finishes. This switch makes dvipng wait at end-of-file for
+ further output, unless it finds the POST marker that indicates the
+ end of the DVI. This is similar to 'tail -f' but for DVI-to-PNG
+ conversion.
+
+'--freetype*'
+ Enable/disable FreeType font rendering (default on). This option
+ is available if the FreeType2 font library was present at
+ compilation time. If this is the case, dvipng will have direct
+ support for PostScript Type1 and TrueType fonts internally, rather
+ than using 'gsftopk' for rendering the fonts. If you have
+ PostScript versions of Computer Modern installed, there will be no
+ need to generate bitmapped (PK) variants on disk of these. Then,
+ you can render images at different (and unusual) resolutions
+ without cluttering the disk with lots of bitmapped fonts. One
+ reason to disable FreeType font rendering would be to generate
+ identical output on different platforms, since FreeType uses the
+ native renderer and therefore can give slightly different output on
+ each platform.
+
+'--gamma NUM'
+ Control the interpolation of colors in the greyscale anti-aliasing
+ color palette. Default value is 1.0. For 0 < NUM < 1, the fonts
+ will be lighter (more like the background), and for NUM > 1, the
+ fonts will be darker (more like the foreground).
+
+'--gif*'
+ The images are output in the GIF format, if GIF support is enabled.
+ This is the default for the 'dvigif' binary, which only will be
+ available when GIF support is enabled. GIF images are palette
+ images (see the '--palette' option) and does not support true alpha
+ channels (see the '--bg' option). See also the '--png' option.
+
+'--height*'
+ Report the height of the image. This only works reliably when the
+ LaTeX style 'preview.sty' from preview-latex is used with the
+ 'active' option. It reports the number of pixels from the top of
+ the image to the baseline of the image. The total height of the
+ image is obtained as the sum of the values reported from '--height'
+ and '--depth'.
+
+'-l [=]NUM'
+ The last page printed will be the first one numbered NUM. Default
+ is the last page in the document. If NUM is prefixed by an equals
+ sign, then it (and the argument to the '-p' option, if specified)
+ is treated as a physical (absolute) page number, rather than a
+ value to compare with the TeX '\count0' values stored in the DVI
+ file. Thus, using '-l =9' will end with the ninth page of the
+ document, no matter what the pages are actually numbered.
+
+'--mode MODE'
+ This option only has an effect when using bitmapped (PK) fonts.
+ Use MODE as the Metafont device name for the PK fonts (both for
+ path searching and font generation). This needs to be augmented
+ with the base device resolution, given with the '--bdpi' option.
+ See the file <ftp://ftp.tug.org/tex/modes.mf> for a list of
+ resolutions and mode names for most devices. *Note
+ (kpathsea)Unable to generate fonts::.
+
+'-M*'
+ This option only has an effect when using bitmapped (PK) fonts. It
+ turns off automatic PK font generation ('mktexpk').
+
+'--nogs*'
+ This switch prohibits the internal call to GhostScript for
+ displaying PostScript specials. '--nogs0' turns the call back on.
+
+'--nogssafer*'
+ Normally, if GhostScript is used to render PostScript specials, the
+ GhostScript interpreter is run with the option '-dSAFER'. The
+ '--nogssafer' option runs GhostScript without '-dSAFER'. The
+ '-dSAFER' option in Ghostscript disables PostScript operators such
+ as deletefile, to prevent possibly malicious PostScript programs
+ from having any effect.
+
+'--norawps*'
+ Some packages generate raw PostScript specials, even non-rendering
+ such specials. This switch turns off the internal call to
+ GhostScript intended to display these raw PostScript specials.
+ '--norawps0' turns the call back on.
+
+'-o NAME'
+ Send output to the file NAME. A single occurrence of '%d' or
+ '%01d', ..., '%09d' will be exchanged for the physical page number
+ (this can be changed, see the '--dvinum' switch). The default
+ output filename is 'FILE%d.png' where the input DVI file was
+ 'FILE.dvi'.
+
+'-O X-OFFSET,Y-OFFSET'
+ Move the origin by X-OFFSET,Y-OFFSET, a comma-separated pair of
+ dimensions such as '.1in,-.3cm'. The origin of the page is shifted
+ from the default position (of one inch down, one inch to the right
+ from the upper left corner of the paper) by this amount.
+
+'-p [=]NUM'
+ The first page printed will be the first one numbered NUM. Default
+ is the first page in the document. If NUM is prefixed by an equals
+ sign, then it (and the argument to the '-l' option, if specified)
+ is treated as a physical (absolute) page number, rather than a
+ value to compare with the TeX '\count0' values stored in the DVI
+ file. Thus, using '-p =3' will start with the third page of the
+ document, no matter what the pages are actually numbered.
+
+'--palette*'
+ When an external image is included, 'dvipng' will automatically
+ switch to truecolor mode, to avoid unnecessary delay and quality
+ reduction, and enable the EPS translator to draw on a transparent
+ background and outside of the boundingbox. This switch will force
+ palette (256-color) output and make 'dvipng' revert to opaque
+ clipped image inclusion. This will also override the '--truecolor'
+ switch if present.
+
+'--picky*'
+ No images are output when a warning occurs. Normally, dvipng will
+ output an image in spite of a warning, but there may be something
+ missing in this image. One reason to use this option would be if
+ you have a more complete but slower fallback converter. Mainly,
+ this is useful for failed figure inclusion and unknown \special
+ occurrences, but warnings will also occur for missing or unknown
+ color specs and missing PK fonts.
+
+'--png*'
+ The images are output in the PNG format. This is the default for
+ the 'dvipng' binary. See also the '--gif' option.
+
+'-pp FIRSTPAGE-LASTPAGE'
+ Print pages FIRSTPAGE through LASTPAGE; but not quite equivalent to
+ '-p FIRSTPAGE -l LASTPAGE'. For example, when rendering a book,
+ there may be several instances of a page in the DVI file (one in
+ '\frontmatter', one in '\mainmatter', and one in '\backmatter').
+ In case of several pages matching, '-pp FIRSTPAGE-LASTPAGE' will
+ render _all_ pages that matches the specified range, while '-p
+ FIRSTPAGE -l LASTPAGE' will render the pages from the _first_
+ occurrence of FIRSTPAGE to the _first_ occurrence of LASTPAGE.
+ This is the (undocumented) behaviour of dvips. In dvipng you can
+ give both kinds of options, in which case you get all pages that
+ matches the range in '-pp' between the pages from '-p' to '-l'.
+ Also multiple '-pp' options accumulate, unlike '-p' and '-l'. The
+ '-' separator can also be ':'. Note that '-pp -1' will be
+ interpreted as "all pages up to and including 1", if you want a
+ page numbered -1 (only the table of contents, say) put '-pp -1--1',
+ or more readable, '-pp -1:-1'.
+
+'-q*'
+ Run quietly. Don't chatter about pages converted, etc. to standard
+ output; report no warnings (only errors) to standard error.
+
+'-Q NUM'
+ Set the quality to NUM. That is, choose the number of antialiasing
+ levels for bitmapped fonts (PK), to be NUM*NUM+1. The default
+ value is 4 which gives 17 levels of antialiasing for antialiased
+ fonts from these two. If FreeType is available, its rendering is
+ unaffected by this option.
+
+'-r*'
+ Toggle output of pages in reverse/forward order. By default, the
+ first page in the DVI is output first.
+
+'--strict*'
+ The program exits when a warning occurs. Normally, dvipng will
+ output an image in spite of a warning, but there may be something
+ missing in this image. One reason to use this option would be if
+ you have a more complete but slower fallback converter. See the
+ '--picky' option above for a list of when warnings occur.
+
+'-T IMAGE_SIZE'
+ Set the image size to IMAGE_SIZE which can be either of 'bbox',
+ 'tight', or a comma-separated pair of dimensions HSIZE,VSIZE such
+ as '.1in,.3cm'. The default is 'bbox' which produces a PNG that
+ includes all ink put on the page and in addition the DVI origin,
+ located 1in from the top and 1in from the left edge of the paper.
+ This usually gives whitespace above and to the left in the produced
+ image. The value 'tight' will make dvipng only include all ink put
+ on the page, producing neat images.
+
+'--truecolor*'
+ This will make 'dvipng' generate truecolor output. Note that
+ truecolor output is automatic if you include an external image in
+ your DVI, e.g., via a PostScript special (i.e., the 'graphics' or
+ 'graphicx' package). This switch is overridden by the '--palette'
+ switch.
+
+'-v*'
+ Enable verbose operation. This will currently indicate what fonts
+ is used, in addition to the usual output.
+
+'--width*'
+ Report the width of the image. See also '--height' and '--depth'.
+
+'-x NUM'
+ This option is deprecated; it should not be used. It is much
+ better to select the output resolution directly with the '-D'
+ option. This option sets the magnification ratio to NUM/1000 and
+ overrides the magnification specified in the DVI file. Must be
+ between 10 and 100000. It is recommended that you use standard
+ magstep values (1095, 1200, 1440, 1728, 2074, 2488, 2986, and so
+ on) to help reduce the total number of PK files generated. NUM may
+ be a real number, not an integer, for increased precision.
+
+'-z NUM'
+ Set the PNG compression level to NUM. This option is enabled if
+ your 'libgd' is new enough. The default compression level is 1,
+ which selects maximum speed at the price of slightly larger PNGs.
+ For an older 'libgd', the hard-soldered value 5 is used. The
+ include file 'png.h' says
+ Currently, valid values range from 0 - 9, corresponding
+ directly to the zlib compression levels 0 - 9 (0 - no
+ compression, 9 - "maximal" compression). Note that tests have
+ shown that zlib compression levels 3-6 usually perform as well
+ as level 9 for PNG images, and do considerably fewer
+ calculations. In the future, these values may not correspond
+ directly to the zlib compression levels.

+5 Graphics
+**********
+
+'dvipng' attempts to handle graphics as included by the 'graphicx' and
+'graphics' packages, without the need of specifying a driver to these
+packages. This means that it recognizes the encapsulated postscript
+inclusion meant for 'dvips', but is also able (from version 1.8) to
+include bitmapped graphics. It also tries to handle some of the raw
+PostScript that is output from various packages. Some of the
+possibilities and problems are mentioned below.
+
+* Menu:
+
+* Encapsulated PostScript:: An internal call to GhostScript
+* Bitmapped graphics:: PNG, JPEG and GIF
+* Raw PostScript:: Ignore or give to GhostScript
+
+
+File: dvipng.info, Node: Encapsulated PostScript, Next: Bitmapped graphics, Up: Graphics
+
+5.1 Encapsulated PostScript
+===========================
+
+When an EPS file is included, a call to GhostScript is performed to
+produce a bitmapped image that can be included. The default is to
+produce an image with transparent background, at the same size as the
+DVI page currently being converted to PNG, and include that as
+foreground on the PNG. Of course, if the image is to be cropped, that is
+done. The included image will be a truecolor image, so for maximum
+performance the output PNG will be in truecolor mode as well.
+
+ This conversion needs the 'pngalpha' output device to be present in
+your copy of GhostScript. If that device is not present, or you use the
+'--palette' switch or request GIF output, the fallback is to use the
+'png16m' device to produce a cropped opaque image for inclusion. Other
+relevant switches are '--noghostscript' and '--nogssafer'. *Note Option
+details::.
+
+ The most common problem with including graphics is an incorrect
+bounding box. Complain to whoever wrote the software that generated the
+file if the bounding box is indeed incorrect. An adjusted boundingbox
+can be specified in the '\includegraphics' call, as in this example
+(using 'graphicx'):
+
+ \includegraphics[bb=10 20 100 200]{imagename.eps}
+
+
+File: dvipng.info, Node: Bitmapped graphics, Next: Raw PostScript, Prev: Encapsulated PostScript, Up: Graphics
+
+5.2 Bitmapped graphics
+======================
+
+dvipng can include PNG, JPEG and GIF graphics. When including such
+images via '\includegraphics' you need to specify the bounding box since
+TeX itself cannot read them from the files in question. The bounding
+box size should be given as '0 0 w h' in pixels, e.g., if the file
+'imagename.png' is 300x400 pixels, the inclusion would read
+
+ \includegraphics[bb=0 0 300 400]{imagename.png}
+
+ The default size is the image size in bp ("big points" in TeX
+nomenclature or PostScript points as other people have it, 72 per inch).
+That is, default resolution will be 72 dpi for included bitmaps, which
+is the default size in the few other bitmap-capable drivers that are
+known to me (dvipdfm and PDFLaTeX).
+
+ If you want 100 dpi you need to specify the width accordingly. You
+just divide your image width by 100: a 135 pixel wide image at 100 dpi
+will take up 1.35 inches. If you want 200 dpi you divide by 200, and so
+on. Simple, eh? The example above at 200 dpi would be 1.5 inches wide:
+
+ \includegraphics[bb=0 0 300 400,witdh=1.5in]{imagename.png}
+
+
+File: dvipng.info, Node: Raw PostScript, Prev: Bitmapped graphics, Up: Graphics
+
+5.3 Raw PostScript
+==================
+
+dvipng attempts to handle raw PostScript. Rendering raw PostScript
+specials is done on top of the page by including a transparent image
+generated by the 'pngalpha' device in GhostScript (automatically
+selecting 'truecolor' mode in dvipng).
+
+ Included PostScript headers are respected, and if the header
+'tex.pro' is included, dvipng also throws in 'color.pro' and
+'special.pro'. The package 'xcolor' includes its own headers with color
+names, and this is not only kept as a PostScript header, but is also
+read and interpreted by dvipng itself. An attempt is also made to
+respect the PGF header. The non-rendering specials from 'hyperref' are
+handled via some heuristics and do not give an error.
+
+ Really rendering and moving things with raw PostScript specials is
+more troublesome. The \rotatebox macro serves as a good example. The
+dvips driver of the graphicx package surrounds DVI glyphs with
+PostScript code so that after conversion by dvips, the glyphs (now
+themselves in PostScript) will be rotated in the desired way. dvipng
+does not handle this, at present. An attempt has been made to handle
+the rendering specials output by PGF (tikz), and also PSTricks. Some
+things work, but others do not. This is especially clear when mixing
+PostScript and DVI rendering commands such as glyphs. dvipng cannot at
+present detect if PostScript code moves 'currentpoint' or rotates the
+frame since GhostScript does not return such information. A
+recommendation would be to produce images from these packages as EPS
+files and include them into your document in the standard manner.
+
+ Another way to handle this would be to use a slower fallback (with
+dvips and gs, for example). If you want to disable raw PostScript
+handling in dvipng, use the switch '--norawps'. This switch turns off
+the internal call to GhostScript intended to display these raw
+PostScript specials. Further, when dvipng encounters raw PostScript and
+the gs call is turned off, it gives a warning. It is now possible to
+use the switch '--picky' to disable page rendering of pages with
+warnings, and use the slower fallback for these pages.

+
+6 Color
+*******
+
+To support color, dvipng recognizes a certain set of specials as
+generated by the 'color' and 'xcolor' style files. These specials start
+with the keyword 'color' or the keyword 'background', followed by a
+color specification.
+
+* Menu:
+
+* Color specifications::
+* Color specials::
+
+
+File: dvipng.info, Node: Color specifications, Next: Color specials, Up: Color
+
+6.1 Color specifications
+========================
+
+The color specification supported by dvipng is by-value or by-name. The
+by-value spec starts with the name of a color model (one of 'rgb',
+'hsb', 'cmy', 'cmyk', or 'gray') followed by the appropriate number of
+parameters. Thus, the color specification 'rgb 0.3 0.4 0.5' would
+correspond to the color that is '0.3 0.4 0.5' in its red, blue and green
+values. The color model used internally in dvipng is 'RGB' (discretized
+to 256 levels), for details on the formulas used in conversion, see the
+'xcolor' documentation.
+
+ By-name color specifications are single (case-dependent) words and
+are compared with color names defined in 'dvipsnam.def' (from the
+'graphics' bundle), 'svgnam.def' and 'xcolor.sty' (from the 'xcolor'
+bundle). See the 'xcolor' documentation for a list of names and the
+corresponding colors.
+
+ On the command-line, the name 'Transparent' can also be used as an
+argument to '--bg' to choose transparent background. *Note Option
+details::.
+
+
+File: dvipng.info, Node: Color specials, Prev: Color specifications, Up: Color
+
+6.2 Color specials
+==================
+
+We will describe 'background' first, since it is the simplest. The
+'background' keyword must be followed by a color specification. That
+color specification is used as a fill color for the background. The
+last 'background' special on a page is the one that gets used, and is
+used for the whole of the page image. (This is possible because the
+prescan phase of dvipng notices all of the color specials so that the
+appropriate information can be written out during the second phase.)
+
+ The 'color' special itself has three forms. The first is just
+'color' followed by a color specification. In this case, the current
+global color is set to that color; the color stack must be empty when
+such a command is executed.
+
+ The second form is 'color push' followed by a color specification.
+This saves the current color on the color stack and sets the color to be
+that given by the color specification. This is the most common way to
+set a color.
+
+ The final form of the 'color' special is just 'color pop', with no
+color specification; this says to pop the color last pushed on the color
+stack from the color stack and set the current color to be that color.
+
+ dvipng correctly handles these color specials across pages, even when
+the pages are rendered repeatedly or in reverse order.

+7.2 Debug options
+=================
+
+The '-d' flag to dvipng helps in tracking down certain errors. The
+parameter to this flag is an integer that tells what errors are
+currently being tracked. To track a certain class of debug messages,
+simply provide the appropriate number given below; if you wish to track
+multiple classes, sum the numbers of the classes you wish to track. To
+track all classes, you can use '-1'.
+
+ Some of these debugging options are actually provided by Kpathsea
+(*note (kpathsea)Debugging::).
+
+ The classes are:

+
+@node Basic usage
+@chapter Basic usage of dvipng
+
+@cindex invoking dvipng
+
+To use dvipng at its simplest, simply type
+
+@example
+dvipng foo
+@end example
+
+@noindent
+where @file{foo.dvi} is the output of @TeX{} that you want to convert to
+PNG format. If there are four pages in @file{foo.dvi}, those pages will
+be output as @file{foo1.png}, @file{foo2.png}, @file{foo3.png}, and
+@file{foo4.png}, respectively.
+
+If you have enabled the PostScript font support (via FreeType),
+fonts will be rendered as they are needed. Otherwise, dvipng will use
+bitmapped (PK) fonts, and if you use PK fonts that have not been used on
+your system before, they may be automatically generated; this process
+can take a few minutes, so progress reports appear by default. The next
+time the same font is used, it will have been saved on disk, so
+rendering will go much faster. (If dvipng tries to endlessly generate
+the same fonts over and over again, something is wrong. @xref{Unable to
+generate fonts,,, kpathsea, Kpathsea}.)
+
+Many options are available (see the next section). For a brief summary
+of available options, just type
+
+@example
+dvipng --help
+@end example
+
+@node Command-line options
+@chapter Command-line options
+
+@cindex command-line options
+@cindex options, dvipng
+
+dvipng has a plethora of command line options. Reading through this
+section will give a good idea of the capabilities of the driver.

+@node Option summary
+@section Option summary
+
+@cindex options, summary
+Here is a handy summary of the options; it is printed out when you run
+dvipng with no arguments or with the standard @samp{--help} option.

+@c man begin OPTIONS
+
+Many of the parameterless options listed here can be turned off by
+suffixing the option with a zero (@samp{0}); for instance, to turn off
+page reversal, use @samp{-r0}. Such options are marked with a trailing
+@samp{*}.
+
+@table @samp
+@item -
+@cindex options, reading from standard input
+@cindex standard input, reading options from
+Read additional options from standard input after processing the command
+line.
+
+@item --help
+Print a usage message and exit.
+
+@item --version
+Print the version number and exit.
+
+@item -bd @var{num}
+@item -bd @var{color_spec}
+@item -bd '@var{num} @var{color_spec}'
+@cindex transparent border width
+@cindex transparent border fallback color
+Set the pixel width of the transparent border (default 0). Using this
+option will make the image edges transparent, but it only affects pixels
+with the background color. Giving a @var{color_spec} will set the
+fallback color, to be used in viewers that cannot handle transparency
+(the default is the background color). The color spec should be in
+@TeX{} color \special syntax, e.g., 'rgb 1.0 0.0 0.0'. Setting the
+fallback color makes the default border width 1 px. @xref{Color}.
+
+@item --bdpi @var{num}
+@cindex base resolution, setting
+This option only has an effect when using bitmapped (PK) fonts. The
+option sets the base (Metafont) resolution, both horizontal and
+vertical, to @var{num} dpi (dots per inch). This option is necessary
+when manually selecting Metafont mode with the --mode option (see
+below).
+
+@item -bg @var{color_spec}
+@cindex background color (option)
+Choose background color for the images. This option will be ignored if
+there is a background color \special in the DVI. The color spec should
+be in @TeX{} color \special syntax, e.g., 'rgb 1.0 0.0 0.0'. You can
+also specify 'Transparent' or 'transparent' which will give you a
+transparent background with the normal background as a fallback color. A
+capitalized 'Transparent' will give a full-alpha transparency, while an
+all-lowercase 'transparent' will give a simple fully transparent
+background with non-transparent antialiased pixels. The latter would be
+suitable for viewers who cannot cope with a true alpha channel. GIF
+images do not support full alpha transparency, so in case of GIF output,
+both variants will use the latter behaviour. @xref{Color}.
+
+@item -d @var{num}
+@cindex debugging
+Set the debug flags, showing what dvipng (thinks it) is doing. This will
+work unless dvipng has been compiled without the @code{DEBUG} option
+(not recommended). Set the flags as you need them, use @samp{-d -1} as
+the first option for maximum output. @xref{Debug options}.
+
+@item -D @var{num}
+@cindex output resolution, setting
+Set the output resolution, both horizontal and vertical, to @var{num}
+dpi (dots per inch).
+
+One may want to adjust this to fit a certain text font size (e.g., on
+a web page), and for a text font height of @var{font_px} pixels (in
+Mozilla) the correct formula is
+@example
+@var{dpi} = @var{font_px} * 72.27 / 10 [px * @TeX{}pt/in / @TeX{}pt]
+@end example
+The last division by ten is due to the standard font height 10pt in
+your document, if you use 12pt, divide by 12. Unfortunately, some
+proprietary browsers have font height in pt (points), not pixels. You
+have to rescale that to pixels, using the screen resolution (default
+is usually 96 dpi) which means the formula is
+@example
+@var{font_px} = @var{font_pt} * 96 / 72 [pt * px/in / (pt/in)]
+@end example
+On some high-res screens, the value is instead 120 dpi. Good luck!
+
+@item --depth*
+@cindex baseline reporting
+@cindex depth reporting
+Report the depth of the image. This only works reliably when the
+@LaTeX{} style @file{preview.sty} from @previewlatex{} is used with
+the @samp{active} option. It reports the number of pixels from the
+bottom of the image to the baseline of the image. This can be used for
+vertical positioning of the image in, e.g., web documents, where one
+would use (Cascading StyleSheets 1)
+@example
+<IMG SRC="@var{filename.png}" STYLE="vertical-align: -@var{depth}px">
+@end example
+The depth is a negative offset in this case, so the minus sign is
+necessary, and the unit is pixels (px).
+
+@item --dvinum*
+Set this option to make the output page number be the @TeX{} page
+numbers rather than the physical page number. See the @samp{-o} switch.
+
+@ignore
+@item -e @var{num}
+@cindex maxdrift
+@cindex accuracy in positioning
+@cindex positioning accuracy
+Maximum drift in pixels of each character from its `true'
+resolution-independent position on the page. The default value of this
+parameter is resolution dependent (it is the number of entries in the
+list [100, 200, 300, 400, 500, 600, 800, 1000, 1200, 1600, 2000, 2400,
+2800, 3200, @dots{}] that are less than or equal to the resolution in
+dots per inch). Allowing individual characters to `drift' from their
+correctly rounded positions by a few pixels, while regaining the true
+position at the beginning of each new word, improves the spacing of
+letters in words.
+
+@item -f*
+@cindex filter, running as a
+@cindex standard I/O
+@cindex pipes, not readable
+@vindex PRINTER@r{, avoided with @samp{-f}}
+Run as a filter. Read the DVI file from standard input and write the
+PostScript to standard output. The standard input must be seekable, so
+it cannot be a pipe. If your input must be a pipe, write a shell script
+that copies the pipe output to a temporary file and then points dvipng at
+this file. This option also disables the automatic reading of the
+@code{PRINTER} environment variable; use @samp{-P$PRINTER} after the
+@samp{-f} to read it anyway. It also turns off the automatic sending of
+control-D if it was turned on with the @samp{-F} option or in the
+configuration file; use @samp{-F} after the @samp{-f} to send it anyway.
+
+@item -k*
+@cindex cropmarks
+Print crop marks. This option increases the paper size (which should be
+specified, either with a paper size special or with the @samp{-T}
+option) by a half inch in each dimension. It translates each page by a
+quarter inch and draws cross-style crop marks. It is mostly useful with
+typesetters that can set the page size automatically. This works by
+downloading @file{crop.pro}.
+@end ignore
+
+@item -fg @var{color_spec}
+@cindex foreground color (option)
+Choose foreground color for the images. This option will be ignored if
+there is a foreground color \special in the DVI. The color spec should
+be in @TeX{} color \special syntax, e.g., 'rgb 1.0 0.0 0.0'.
+@xref{Color}.
+
+@item --follow*
+@cindex follow mode
+Wait for data at end-of-file. One of the benefits of dvipng is that it
+does not read the postamble, so it can be started before @TeX{}
+finishes. This switch makes dvipng wait at end-of-file for further
+output, unless it finds the POST marker that indicates the end of the
+DVI. This is similar to @samp{tail -f} but for DVI-to-PNG conversion.
+
+@item --freetype*
+@cindex FreeType font rendering
+Enable/disable FreeType font rendering (default on). This option is
+available if the FreeType2 font library was present at compilation time.
+If this is the case, dvipng will have direct support for PostScript
+Type1 and TrueType fonts internally, rather than using @samp{gsftopk}
+for rendering the fonts. If you have PostScript versions of Computer
+Modern installed, there will be no need to generate bitmapped (PK)
+variants on disk of these. Then, you can render images at different (and
+unusual) resolutions without cluttering the disk with lots of bitmapped
+fonts.
+One reason to disable FreeType font rendering would be to generate
+identical output on different platforms, since FreeType uses the native
+renderer and therefore can give slightly different output on each platform.
+
+@item --gamma @var{num}
+@cindex gamma
+@cindex dark fonts
+@cindex light fonts
+@cindex fuzzy images
+Control the interpolation of colors in the greyscale anti-aliasing
+color palette. Default value is 1.0. For 0 < @var{num} < 1, the
+fonts will be lighter (more like the background), and for @var{num} >
+1, the fonts will be darker (more like the foreground).
+
+@item --gif*
+@cindex GIF image format
+The images are output in the GIF format, if GIF support is enabled.
+This is the default for the @samp{dvigif} binary, which only will be
+available when GIF support is enabled. GIF images are palette images
+(see the @samp{--palette} option) and does not support true alpha
+channels (see the @samp{--bg} option). See also the @samp{--png}
+option.
+
+@item --height*
+@cindex baseline reporting
+@cindex height reporting
+Report the height of the image. This only works reliably when the
+@LaTeX{} style @file{preview.sty} from @previewlatex{} is used with
+the @samp{active} option. It reports the number of pixels from the top
+of the image to the baseline of the image. The total height of the
+image is obtained as the sum of the values reported from
+@samp{--height} and @samp{--depth}.
+
+@item -l [=]@var{num}
+@cindex last page printed
+@cindex page, last printed
+@cindex physical page number, and @samp{-l}
+@cindex absolute page number, and @samp{-l}
+The last page printed will be the first one numbered @var{num}. Default
+is the last page in the document. If @var{num} is prefixed by an equals
+sign, then it (and the argument to the @samp{-p} option, if specified)
+is treated as a physical (absolute) page number, rather than a value to
+compare with the @TeX{} @samp{\count0} values stored in the DVI file.
+Thus, using @samp{-l =9} will end with the ninth page of the document,
+no matter what the pages are actually numbered.
+
+@item --mode @var{mode}
+@cindex mode name, specifying
+@cindex Metafont mode, specifying
+This option only has an effect when using bitmapped (PK) fonts. Use
+@var{mode} as the Metafont device name for the PK fonts (both for path
+searching and font generation). This needs to be augmented with the base
+device resolution, given with the @samp{--bdpi} option. See the file
+@url{ftp://ftp.tug.org/tex/modes.mf} for a list of resolutions and mode
+names for most devices. @xref{Unable to generate fonts,,, kpathsea,
+Kpathsea}.
+
+@item -M*
+@cindex font generation, avoiding
+@pindex mktexpk@r{, avoiding}
+@c this description repeated in kpathsea.texi
+This option only has an effect when using bitmapped (PK) fonts. It turns
+off automatic PK font generation (@file{mktexpk}).
+@ignore
+@flindex missfont.log
+If @code{mktexpk}, the invocation is appended to a file
+@file{missfont.log} (by default) in the current directory. You can then
+execute the log file to create the missing files after fixing the
+problem.
+@vindex TEXMFOUTPUT
+@vindex MISSFONT_LOG
+If the current directory is not writable and the environment variable or
+configuration file value @samp{TEXMFOUTPUT} is set, its value is used.
+Otherwise, nothing is written. The name @samp{missfont.log} is
+overridden by the @samp{MISSFONT_LOG} environment variable or
+configuration file value.
+@end ignore
+
+@item --nogs*

+
+@item --nogssafer*
+@cindex GhostScript and -dSAFER
+@cindex -dSAFER
+Normally, if GhostScript is used to render PostScript specials, the
+GhostScript interpreter is run with the option @samp{-dSAFER}. The
+@samp{--nogssafer} option runs GhostScript without @samp{-dSAFER}. The
+@samp{-dSAFER} option in Ghostscript disables PostScript operators such
+as deletefile, to prevent possibly malicious PostScript programs from
+having any effect.
+
+@item --norawps*
+@cindex PostScript, turning off raw PostScript specials
+Some packages generate raw PostScript specials, even non-rendering such
+specials. This switch turns off the internal call to GhostScript
+intended to display these raw PostScript specials. @samp{--norawps0}
+turns the call back on.
+
+@item -o @var{name}
+@cindex output, redirecting
+@cindex standard output, output to
+Send output to the file @var{name}. A single occurrence of @samp{%d} or
+@samp{%01d}, @dots{}, @samp{%09d} will be exchanged for the physical
+page number (this can be changed, see the @samp{--dvinum} switch). The
+default output filename is @samp{@var{file}%d.png} where the input DVI
+file was @samp{@var{file}.dvi}.
+
+@item -O @var{x-offset},@var{y-offset}
+@cindex offset pages
+Move the origin by @var{x-offset},@var{y-offset}, a comma-separated
+pair of dimensions such as @samp{.1in,-.3cm}.
+@c (@pxref{papersize special}).
+The origin of the page is shifted from the default position
+(of one inch down, one inch to the right from the upper left corner of
+the paper) by this amount.
+
+@item -p [=]@var{num}
+@cindex first page printed
+@cindex page, first printed
+@cindex physical page number, and @samp{-p}
+@cindex absolute page number, and @samp{-p}
+The first page printed will be the first one numbered @var{num}. Default
+is the first page in the document. If @var{num} is prefixed by an
+equals sign, then it (and the argument to the @samp{-l} option, if
+specified) is treated as a physical (absolute) page number, rather than
+a value to compare with the @TeX{} @samp{\count0} values stored in the
+DVI file. Thus, using @samp{-p =3} will start with the third page of
+the document, no matter what the pages are actually numbered.
+
+@item --palette*
+@cindex forcing palette output
+When an external image is included, @samp{dvipng} will automatically
+switch to truecolor mode, to avoid unnecessary delay and quality
+reduction, and enable the EPS translator to draw on a transparent
+background and outside of the boundingbox. This switch will force
+palette (256-color) output and make @samp{dvipng} revert to opaque
+clipped image inclusion. This will also override the @samp{--truecolor}
+switch if present.
+
+@item --picky*
+@cindex no erroneous images
+No images are output when a warning occurs. Normally, dvipng will
+output an image in spite of a warning, but there may be something
+missing in this image. One reason to use this option would be if you
+have a more complete but slower fallback converter. Mainly, this is
+useful for failed figure inclusion and unknown \special occurrences,
+but warnings will also occur for missing or unknown color specs and
+missing PK fonts.
+
+@item --png*
+@cindex PNG image format
+The images are output in the PNG format. This is the default for the
+@samp{dvipng} binary. See also the @samp{--gif} option.
+
+@item -pp @var{firstpage}-@var{lastpage}
+@cindex page range
+Print pages @var{firstpage} through @var{lastpage}; but not quite
+equivalent to @samp{-p @var{firstpage} -l @var{lastpage}}. For example,
+when rendering a book, there may be several instances of a page in the
+DVI file (one in @code{\frontmatter}, one in @code{\mainmatter}, and one
+in @code{\backmatter}). In case of several pages matching, @samp{-pp
+@var{firstpage}-@var{lastpage}} will render @emph{all} pages that
+matches the specified range, while @samp{-p @var{firstpage} -l
+@var{lastpage}} will render the pages from the @emph{first} occurrence
+of @var{firstpage} to the @emph{first} occurrence of @var{lastpage}.
+This is the (undocumented) behaviour of dvips. In dvipng you can give
+both kinds of options, in which case you get all pages that matches the
+range in @samp{-pp} between the pages from @samp{-p} to @samp{-l}. Also
+multiple @samp{-pp} options accumulate, unlike @samp{-p} and @samp{-l}.
+The @samp{-} separator can also be @samp{:}. Note that @samp{-pp -1}
+will be interpreted as "all pages up to and including 1", if you want a
+page numbered -1 (only the table of contents, say) put @samp{-pp -1--1},
+or more readable, @samp{-pp -1:-1}.

+@cindex quality
+Set the quality to @var{num}. That is, choose the number of antialiasing
+levels for bitmapped fonts (PK), to be
+@var{num}*@var{num}+1. The default value is 4 which gives 17 levels of
+antialiasing for antialiased fonts from these two. If FreeType is

+@item --strict*
+@cindex exit on erroneous images
+The program exits when a warning occurs. Normally, dvipng will output

+@samp{bbox}, @samp{tight}, or a comma-separated pair of dimensions
+@var{hsize},@var{vsize} such as @samp{.1in,.3cm}. The default is
+@samp{bbox} which produces a PNG that includes all ink put on the page
+and in addition the DVI origin, located 1in from the top and 1in from
+the left edge of the paper. This usually gives whitespace above and to
+the left in the produced image. The value @samp{tight} will make dvipng
+only include all ink put on the page, producing neat images.

+truecolor output is automatic if you include an external image in your

+
+@item --width*
+@cindex width reporting
+Report the width of the image. See also @samp{--height} and
+@samp{--depth}.
+
+@item -x @var{num}
+@cindex magnification, overriding DVI
+This option is deprecated; it should not be used. It is much better to
+select the output resolution directly with the @samp{-D} option. This
+option sets the magnification ratio to @math{@var{num}/1000} and
+overrides the magnification specified in the DVI file. Must be between
+10 and 100000. It is recommended that you use standard magstep values
+(1095, 1200, 1440, 1728, 2074, 2488, 2986, and so on) to help reduce the
+total number of PK files generated. @var{num} may be a real number, not
+an integer, for increased precision.
+
+@item -z @var{num}
+@cindex compression
+Set the PNG compression level to @var{num}. This option is enabled if
+your @samp{libgd} is new enough. The default compression level is 1,
+which selects maximum speed at the price of slightly larger PNGs. For an
+older @samp{libgd}, the hard-soldered value 5 is used. The include file
+@samp{png.h} says
+@ifclear man
+@quotation
+Currently, valid values range from 0 - 9, corresponding directly to the
+zlib compression levels 0 - 9 (0 - no compression, 9 - "maximal"
+compression). Note that tests have shown that zlib compression levels
+3-6 usually perform as well as level 9 for PNG images, and do
+considerably fewer calculations. In the future, these values may not
+correspond directly to the zlib compression levels.

+
+@samp{dvipng} attempts to handle graphics as included by the
+@samp{graphicx} and @samp{graphics} packages, without the need of
+specifying a driver to these packages. This means that it recognizes
+the encapsulated postscript inclusion meant for @samp{dvips}, but is
+also able (from version 1.8) to include bitmapped graphics. It also
+tries to handle some of the raw PostScript that is output from various
+packages. Some of the possibilities and problems are mentioned below.
+
+@menu
+* Encapsulated PostScript:: An internal call to GhostScript
+* Bitmapped graphics:: PNG, JPEG and GIF
+* Raw PostScript:: Ignore or give to GhostScript
+@end menu
+
+@node Encapsulated PostScript
+@section Encapsulated PostScript
+
+When an EPS file is included, a call to GhostScript is performed to
+produce a bitmapped image that can be included. The default is to
+produce an image with transparent background, at the same size as the
+DVI page currently being converted to PNG, and include that as
+foreground on the PNG. Of course, if the image is to be cropped, that
+is done. The included image will be a truecolor image, so for maximum
+performance the output PNG will be in truecolor mode as well.
+
+This conversion needs the @samp{pngalpha} output device to be present
+in your copy of GhostScript. If that device is not present, or you use
+the @samp{--palette} switch or request GIF output, the fallback is to
+use the @samp{png16m} device to produce a cropped opaque image for
+inclusion. Other relevant switches are @samp{--noghostscript} and
+@samp{--nogssafer}. @xref{Option details}.
+
+@cindex PostScript inclusion problems
+The most common problem with including graphics is an incorrect
+bounding box. Complain to whoever wrote the software that generated
+the file if the bounding box is indeed incorrect. An adjusted
+boundingbox can be specified in the @samp{\includegraphics} call, as
+in this example (using @samp{graphicx}):
+
+@example
+\includegraphics[bb=10 20 100 200]@{imagename.eps@}
+@end example
+
+
+@node Bitmapped graphics
+@section Bitmapped graphics
+
+dvipng can include PNG, JPEG and GIF graphics. When including such
+images via @samp{\includegraphics} you need to specify the bounding
+box since @TeX{} itself cannot read them from the files in question.
+The bounding box size should be given as @samp{0 0 w h} in pixels,
+e.g., if the file @samp{imagename.png} is 300x400 pixels, the
+inclusion would read
+
+@example
+\includegraphics[bb=0 0 300 400]@{imagename.png@}
+@end example
+
+The default size is the image size in bp (``big points'' in TeX
+nomenclature or PostScript points as other people have it, 72 per inch).
+That is, default resolution will be 72 dpi for included bitmaps, which
+is the default size in the few other bitmap-capable drivers that are
+known to me (dvipdfm and PDFLaTeX).
+
+If you want 100 dpi you need to specify the width accordingly. You
+just divide your image width by 100: a 135 pixel wide image at 100 dpi
+will take up 1.35 inches. If you want 200 dpi you divide by 200, and
+so on. Simple, eh? The example above at 200 dpi would be 1.5 inches
+wide:
+
+@example
+\includegraphics[bb=0 0 300 400,witdh=1.5in]@{imagename.png@}
+@end example
+
+@node Raw PostScript
+@section Raw PostScript
+
+dvipng attempts to handle raw PostScript. Rendering raw PostScript
+specials is done on top of the page by including a transparent image
+generated by the @samp{pngalpha} device in GhostScript (automatically
+selecting @samp{truecolor} mode in dvipng).
+
+Included PostScript headers are respected, and if the header
+@samp{tex.pro} is included, dvipng also throws in @samp{color.pro} and
+@samp{special.pro}. The package @samp{xcolor} includes its own headers
+with color names, and this is not only kept as a PostScript header, but
+is also read and interpreted by dvipng itself. An attempt is also made
+to respect the PGF header. The non-rendering specials from
+@samp{hyperref} are handled via some heuristics and do not give an
+error.
+
+Really rendering and moving things with raw PostScript specials is more
+troublesome. The \rotatebox macro serves as a good example. The dvips
+driver of the graphicx package surrounds DVI glyphs with PostScript code
+so that after conversion by dvips, the glyphs (now themselves in
+PostScript) will be rotated in the desired way. dvipng does not handle
+this, at present. An attempt has been made to handle the rendering
+specials output by PGF (tikz), and also PSTricks. Some things work, but
+others do not. This is especially clear when mixing PostScript and DVI
+rendering commands such as glyphs. dvipng cannot at present detect if
+PostScript code moves @samp{currentpoint} or rotates the frame since
+GhostScript does not return such information. A recommendation would be
+to produce images from these packages as EPS files and include them into
+your document in the standard manner.
+
+Another way to handle this would be to use a slower fallback (with dvips
+and gs, for example). If you want to disable raw PostScript handling in
+dvipng, use the switch @samp{--norawps}. This switch turns off the
+internal call to GhostScript intended to display these raw PostScript
+specials. Further, when dvipng encounters raw PostScript and the gs call
+is turned off, it gives a warning. It is now possible to use the switch
+@samp{--picky} to disable page rendering of pages with warnings, and use
+the slower fallback for these pages.
+
+@node Color
+@chapter Color
+
+To support color, dvipng recognizes a certain set of specials as
+generated by the @samp{color} and @samp{xcolor} style files. These
+specials start with the keyword @samp{color} or the keyword
+@samp{background}, followed by a color specification.
+
+@menu
+* Color specifications::
+* Color specials::
+@end menu
+
+
+@node Color specifications
+@section Color specifications
+
+@cindex color specifications
+
+The color specification supported by dvipng is by-value or by-name. The
+by-value spec starts with the name of a color model (one of @samp{rgb},
+@samp{hsb}, @samp{cmy}, @samp{cmyk}, or @samp{gray}) followed by the
+appropriate number of parameters. Thus, the color specification
+@samp{rgb 0.3 0.4 0.5} would correspond to the color that is @samp{0.3
+0.4 0.5} in its red, blue and green values. The color model used
+internally in dvipng is @samp{RGB} (discretized to 256 levels), for
+details on the formulas used in conversion, see the @samp{xcolor}
+documentation.
+
+By-name color specifications are single (case-dependent) words and are
+compared with color names defined in @samp{dvipsnam.def} (from the
+@samp{graphics} bundle), @samp{svgnam.def} and @samp{xcolor.sty} (from
+the @samp{xcolor} bundle). See the @samp{xcolor} documentation for a
+list of names and the corresponding colors.
+
+On the command-line, the name @samp{Transparent} can also be used as
+an argument to @samp{--bg} to choose transparent background.
+@xref{Option details}.
+
+@node Color specials
+@section Color specials
+
+We will describe @samp{background} first, since it is the simplest. The
+@samp{background} keyword must be followed by a color specification.
+That color specification is used as a fill color for the background. The
+last @samp{background} special on a page is the one that gets used, and
+is used for the whole of the page image. (This is possible because the
+prescan phase of dvipng notices all of the color specials so that the
+appropriate information can be written out during the second phase.)
+
+The @samp{color} special itself has three forms. The first is just
+@samp{color} followed by a color specification. In this case, the
+current global color is set to that color; the color stack must be empty
+when such a command is executed.
+
+The second form is @samp{color push} followed by a color specification.
+This saves the current color on the color stack and sets the color to be
+that given by the color specification. This is the most common way to
+set a color.
+
+The final form of the @samp{color} special is just @samp{color pop},
+with no color specification; this says to pop the color last pushed on
+the color stack from the color stack and set the current color to be
+that color.
+
+dvipng correctly handles these color specials across pages, even when
+the pages are rendered repeatedly or in reverse order.

+@section Prerequisites
+
+@itemize @bullet
+@item The GD Graphics Draw library, libgd
+
+The drawing library @samp{libgd} is necessary, and is downloadable at
+@uref{https://bitbucket.org/libgd/gd-libgd/downloads}, and there are
+binary packages for most operating systems from their respective
+distributors. In any case, the library installs using @samp{autoconf} so
+it should not be difficult for you to install it from source, and then
+proceed with installing dvipng.
+
+@item The path-searching library kpathsea
+
+Kpathsea is most likely included in your @LaTeX{} installation, but it
+may happen that ./configure does not find it; see below. If you do not
+have it, download it from @uref{http://www.ctan.org} and compile it.
+I have no experience with this, so I cannot help much here.
+
+@item The font-rendering library FreeType 2
+
+While not strictly necessary, a recent FreeType 2 is recommended since
+dvipng currently will produce better-quality images when this library is
+available. To take advantage of this, you should have at least FreeType
+2.1.9.
+
+FreeType 2 will enable direct support for PostScript and TrueType fonts,
+so that dvipng will not need to generate bitmapped variants on disk of
+the @TeX{} fonts since modern @TeX{} distributions include PostScript
+versions of them. Then, you can render images at different (and unusual)
+resolutions without cluttering the disk with lots of bitmapped fonts.
+
+Finally, it will enable subfont support in dvipng. That is, if you want
+to render CJK-@LaTeX{} characters, you must have FreeType 2 installed.
+
+@item libpng and libz
+
+To be able to compress and write PNG files to disk, dvipng (or really
+libgd) uses libpng which in turn uses libz. These should be available on
+any modern system, if not, download them and install them.
+
+@item The @code{texinfo} package
+
+This is needed for building the documentation.
+@end itemize
+
+@node Configure
+@section Configure
+
+The first step is to configure the source code, telling it where

+@end example
+
+(Note: if you have fetched dvipng from CVS rather than a regular
+release, you will have to first generate @file{./configure} by running
+@code{autoconf} 2.53 or later.)
+
+On many machines, you will not need to specify any options, but if
+@code{configure} cannot determine something on its own, you'll need to
+help it out. For a list of the options type
+
+@example
+./configure --help
+@end example
+
+On some machines, the libraries will be installed in directories that
+are not in the linker's search path. This will generate an error when
+running @file{./configure}, indicating that it cannot find libgd or
+libkpathsea (most likely). You then need to specify the path to the
+respective library's object files. They are typically called e.g.,
+@file{libgd.a} or @file{libgd.so}. If they are located in e.g.,
+@file{/sw/local/lib}, do
+
+@example
+./configure LDFLAGS=-L/sw/local/lib
+@end example
+
+If the library is available as a shared object file (@file{.so}), the
+runtime linker may also need to be told where to find the library,
+then use
+
+@example
+./configure LDFLAGS='-L/sw/local/lib -R/sw/local/lib'
+@end example
+
+When either of these is necessary, it is likely that the C header
+files are also installed in directories that are not in the C
+preprocessor's search path. This will also generate an error when
+running @file{./configure}, indicating that it cannot find e.g.,
+@file{gd.h} or @file{kpathsea.h} (most likely). You then need to
+specify the path to the respective library's C header files. If they
+are located in e.g., @file{/sw/local/include}, do
+
+@example
+./configure CPPFLAGS=-I/sw/local/include
+@end example
+
+On my SUN Solaris workstation, I had to combine this into
+
+@example
+./configure CPPFLAGS='-I/sw/local/include -I/sw/tex/teTeX/1.0/include'\
+ LDFLAGS='-L/sw/local/lib -R/sw/local/lib -L/sw/tex/teTeX/1.0/lib/'
+@end example
+
+@noindent
+where the backslash denotes a continuation of the line.
+
+@node Build/install
+@section Build/install
+
+Once @file{configure} has been run, simply enter
+
+@example
+make
+@end example
+
+@noindent
+at the prompt to compile the C code, and build the documentation files.
+To install the files into the locations chosen earlier, type
+
+@example
+make install
+@end example
+
+@noindent
+You may need special privileges to install, e.g., if you are installing
+into system directories.
+
+@node Installation outside the texmf tree
+@section Installation outside the texmf tree
+
+In some cases, a dvipng binary installed outside the texmf tree will
+not be able to find virtual fonts, or the PostScript font maps
+(normally used by dvips). This may be because @emph{only}
+$SELFAUTOLOC, $SELFAUTODIR, and $SELFAUTOPARENT are used in the texmf
+tree configuration file @samp{texmf.cnf}. If so, give the switch
+@samp{--enable-selfauto-set} to @samp{./configure}. This will make
+dvipng adjust these three internally so that kpathsea thinks that
+dvipng @emph{is} installed in the texmf tree.
+
+@node Advice for non-privileged users
+@section Installation for non-privileged users
+
+Often people without system administration privileges want to install
+software for their private use. In that case you need to specify more
+options to the @file{configure} script, usually this is done by using
+the @samp{--prefix} option to the @file{configure} script, and let it
+point to the personal home directory. In that way, resulting binaries
+will be installed under the @file{bin} subdirectory of your home
+directory, manual pages under @file{man} and so on. That way, it is
+reasonably easy to maintain a bunch of additional packages, since the
+prefix argument is supported by most @file{configure} scripts.
+
+You'll have to add something like @file{/home/myself/bin} to your
+@code{PATH} shell variable, if it isn't there already, and similarly
+set the @code{INFOPATH} and @code{MANPATH} variables to be able to
+access the documentation.

+@c -----------------------
+
+This program makes PNG and/or GIF graphics from DVI files as obtained
+from @TeX{} and its relatives.
+
+If GIF support is enabled, GIF output is chosen by using the
+@samp{dvigif} binary or with the @samp{--gif} option.
+
+@ifclear man
+
+It is intended to produce anti-aliased screen-resolution images as fast
+as is possible. The target audience is people who need to generate and
+regenerate many images again and again. The primary target is the
+@previewlatex{} (X)Emacs package, a package to preview formulas from
+within (X)Emacs. Yes, you get to see your formulas in the (X)Emacs
+buffer, see @url{http://www.gnu.org/software/auctex/preview-latex.html}.
+
+Another example is WeBWorK, an internet-based method for delivering
+homework problems to students over the internet, giving students
+instant feedback as to whether or not their answers are correct, see
+@url{http://webwork.math.rochester.edu}.
+
+A more recent addition to the dvipng-using applications out there is
+MediaWiki, the software behind Wikipedia and many other wikis out
+there. Dvipng is used to render mathematical formulae from version
+1.8.0 of MediaWiki, see @url{http://www.mediawiki.org}.
+
+Other applications may also benefit, like web applications as latex2html
+and WYSIWYG editors like LyX.
+
+@ifset rawfile
+@section Benefits of dvipng
+@end ifset
+@end ifclear
+
+The benefits of @samp{dvipng}/@samp{dvigif} include
+
+@itemize @bullet
+@item
+Speed. It is a very fast bitmap-rendering code for DVI files, which
+makes it suitable for generating large amounts of images on-the-fly,
+as needed in @previewlatex{}, WeBWorK and others.
+
+@item
+It does not read the postamble, so it can be started before @TeX{}
+finishes. There is a @samp{--follow} switch that makes dvipng wait at
+end-of-file for further output, unless it finds the POST marker that
+indicates the end of the DVI.
+
+@item
+Interactive query of options. dvipng can read options interactively
+through stdin, and all options are usable. It is even possible to change
+the input file through this interface.
+
+@item
+Supports PK, VF, PostScript Type1, and TrueType fonts, subfonts (i.e.,
+as used in CJK-@LaTeX{}), color specials, and inclusion of PostScript,
+PNG, JPEG or GIF images.
+
+@item
+and more...
+
+@end itemize
+
+@ifset rawfile
+@section Installation
+
+Read @file{INSTALL}, included in the distribution.
+
+@section Usage
+
+To use dvipng at its simplest, simply type
+
+@example
+dvipng foo
+@end example
+
+@noindent
+where @file{foo.dvi} is the output of @TeX{} that you want to convert to
+PNG format. If there are four pages in @file{foo.dvi}, those pages will
+be output as @file{foo1.png}, @file{foo2.png}, @file{foo3.png}, and
+@file{foo4.png}, respectively.
+
+Many options are available (see the info manual). For a brief summary
+of available options, just type
+
+@example
+dvipng --help
+@end example
+
+@section Availability
+
+The dvipng package is available at Savannah, the GNU project site. Since
+dvipng is not part of the GNU project, although released under the GNU
+GPL, the web address is
+@url{http://savannah.nongnu.org/projects/dvipng}. Instructions for
+anonymous CVS access can be found at
+@url{http://savannah.nongnu.org/cvs/?group=dvipng}.
+
+@section Contacts
+
+Bug reports should be sent to @email{dvipng@@nongnu.org}.
+
+Questions, suggestions for new features, pleas for help, and/or praise
+should go to @email{dvipng@@nongnu.org}. For more information on this
+mailing list, send a message with just the word `help' as subject or
+body to @email{dvipng-request@@nongnu.org} or look at
+@url{http://lists.nongnu.org/mailman/listinfo/dvipng}.
+
+Offers to support further development will be appreciated. For developer
+access, ask on @email{dvipng@@nongnu.org}.

+ GNU GENERAL PUBLIC LICENSE
+ Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+ The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works. By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users. We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors. You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+ To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights. Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received. You must make sure that they, too, receive
+or can get the source code. And you must show them these terms so they
+know their rights.
+
+ Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+ For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software. For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+ Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so. This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software. The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable. Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products. If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+ Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary. To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ TERMS AND CONDITIONS
+
+ 0. Definitions.
+
+ "This License" refers to version 3 of the GNU General Public License.
+
+ "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+ "The Program" refers to any copyrightable work licensed under this
+License. Each licensee is addressed as "you". "Licensees" and
+"recipients" may be individuals or organizations.
+
+ To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy. The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+ A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+ To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy. Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+ To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies. Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+ An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License. If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+ 1. Source Code.
+
+ The "source code" for a work means the preferred form of the work
+for making modifications to it. "Object code" means any non-source
+form of a work.
+
+ A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+ The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form. A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+ The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities. However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work. For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+ The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+ The Corresponding Source for a work in source code form is that
+same work.
+
+ 2. Basic Permissions.
+
+ All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met. This License explicitly affirms your unlimited
+permission to run the unmodified Program. The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work. This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+ You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force. You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright. Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+ Conveying under any other circumstances is permitted solely under
+the conditions stated below. Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+ 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+ No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+ When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+ 4. Conveying Verbatim Copies.
+
+ You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+ You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+ 5. Conveying Modified Source Versions.
+
+ You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+ a) The work must carry prominent notices stating that you modified
+ it, and giving a relevant date.
+
+ b) The work must carry prominent notices stating that it is
+ released under this License and any conditions added under section
+ 7. This requirement modifies the requirement in section 4 to
+ "keep intact all notices".
+
+ c) You must license the entire work, as a whole, under this
+ License to anyone who comes into possession of a copy. This
+ License will therefore apply, along with any applicable section 7
+ additional terms, to the whole of the work, and all its parts,
+ regardless of how they are packaged. This License gives no
+ permission to license the work in any other way, but it does not
+ invalidate such permission if you have separately received it.
+
+ d) If the work has interactive user interfaces, each must display
+ Appropriate Legal Notices; however, if the Program has interactive
+ interfaces that do not display Appropriate Legal Notices, your
+ work need not make them do so.
+
+ A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit. Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+ 6. Conveying Non-Source Forms.
+
+ You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+ a) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by the
+ Corresponding Source fixed on a durable physical medium
+ customarily used for software interchange.
+
+ b) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by a
+ written offer, valid for at least three years and valid for as
+ long as you offer spare parts or customer support for that product
+ model, to give anyone who possesses the object code either (1) a
+ copy of the Corresponding Source for all the software in the
+ product that is covered by this License, on a durable physical
+ medium customarily used for software interchange, for a price no
+ more than your reasonable cost of physically performing this
+ conveying of source, or (2) access to copy the
+ Corresponding Source from a network server at no charge.
+
+ c) Convey individual copies of the object code with a copy of the
+ written offer to provide the Corresponding Source. This
+ alternative is allowed only occasionally and noncommercially, and
+ only if you received the object code with such an offer, in accord
+ with subsection 6b.
+
+ d) Convey the object code by offering access from a designated
+ place (gratis or for a charge), and offer equivalent access to the
+ Corresponding Source in the same way through the same place at no
+ further charge. You need not require recipients to copy the
+ Corresponding Source along with the object code. If the place to
+ copy the object code is a network server, the Corresponding Source
+ may be on a different server (operated by you or a third party)
+ that supports equivalent copying facilities, provided you maintain
+ clear directions next to the object code saying where to find the
+ Corresponding Source. Regardless of what server hosts the
+ Corresponding Source, you remain obligated to ensure that it is
+ available for as long as needed to satisfy these requirements.
+
+ e) Convey the object code using peer-to-peer transmission, provided
+ you inform other peers where the object code and Corresponding
+ Source of the work are being offered to the general public at no
+ charge under subsection 6d.
+
+ A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+ A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling. In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage. For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product. A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+ "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source. The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+ If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information. But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+ The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed. Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+ Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+ 7. Additional Terms.
+
+ "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law. If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+ When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it. (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.) You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+ Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+ a) Disclaiming warranty or limiting liability differently from the
+ terms of sections 15 and 16 of this License; or
+
+ b) Requiring preservation of specified reasonable legal notices or
+ author attributions in that material or in the Appropriate Legal
+ Notices displayed by works containing it; or
+
+ c) Prohibiting misrepresentation of the origin of that material, or
+ requiring that modified versions of such material be marked in
+ reasonable ways as different from the original version; or
+
+ d) Limiting the use for publicity purposes of names of licensors or
+ authors of the material; or
+
+ e) Declining to grant rights under trademark law for use of some
+ trade names, trademarks, or service marks; or
+
+ f) Requiring indemnification of licensors and authors of that
+ material by anyone who conveys the material (or modified versions of
+ it) with contractual assumptions of liability to the recipient, for
+ any liability that these contractual assumptions directly impose on
+ those licensors and authors.
+
+ All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10. If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term. If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+ If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+ Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+ 8. Termination.
+
+ You may not propagate or modify a covered work except as expressly
+provided under this License. Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+ However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+ Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License. If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+ 9. Acceptance Not Required for Having Copies.
+
+ You are not required to accept this License in order to receive or
+run a copy of the Program. Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance. However,
+nothing other than this License grants you permission to propagate or
+modify any covered work. These actions infringe copyright if you do
+not accept this License. Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+ 10. Automatic Licensing of Downstream Recipients.
+
+ Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License. You are not responsible
+for enforcing compliance by third parties with this License.
+
+ An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations. If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+ You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License. For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+ 11. Patents.
+
+ A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based. The
+work thus licensed is called the contributor's "contributor version".
+
+ A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version. For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+ Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+ In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement). To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+ If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients. "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+ If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+ A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License. You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+ Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+ 12. No Surrender of Others' Freedom.
+
+ If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all. For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+ 13. Use with the GNU Affero General Public License.
+
+ Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work. The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+ 14. Revised Versions of this License.
+
+ The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation. If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+ If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+ Later license versions may give you additional or different
+permissions. However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+ 15. Disclaimer of Warranty.
+
+ THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. Limitation of Liability.
+
+ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+ 17. Interpretation of Sections 15 and 16.
+
+ If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software: you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation, either version 3 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program. If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+ If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+ <program> Copyright (C) <year> <name of author>
+ This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+ You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+ The GNU General Public License does not permit incorporating your program
+into proprietary programs. If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library. If this is what you want to do, use the GNU Lesser General
+Public License instead of this License. But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+ GNU LESSER GENERAL PUBLIC LICENSE
+ Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+ This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+ 0. Additional Definitions.
+
+ As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+ "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+ An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+ A "Combined Work" is a work produced by combining or linking an
+Application with the Library. The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+ The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+ The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+ 1. Exception to Section 3 of the GNU GPL.
+
+ You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+ 2. Conveying Modified Versions.
+
+ If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+ a) under this License, provided that you make a good faith effort to
+ ensure that, in the event an Application does not supply the
+ function or data, the facility still operates, and performs
+ whatever part of its purpose remains meaningful, or
+
+ b) under the GNU GPL, with none of the additional permissions of
+ this License applicable to that copy.
+
+ 3. Object Code Incorporating Material from Library Header Files.
+
+ The object code form of an Application may incorporate material from
+a header file that is part of the Library. You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+ a) Give prominent notice with each copy of the object code that the
+ Library is used in it and that the Library and its use are
+ covered by this License.
+
+ b) Accompany the object code with a copy of the GNU GPL and this license
+ document.
+
+ 4. Combined Works.
+
+ You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+ a) Give prominent notice with each copy of the Combined Work that
+ the Library is used in it and that the Library and its use are
+ covered by this License.
+
+ b) Accompany the Combined Work with a copy of the GNU GPL and this license
+ document.
+
+ c) For a Combined Work that displays copyright notices during
+ execution, include the copyright notice for the Library among
+ these notices, as well as a reference directing the user to the
+ copies of the GNU GPL and this license document.
+
+ d) Do one of the following:
+
+ 0) Convey the Minimal Corresponding Source under the terms of this
+ License, and the Corresponding Application Code in a form
+ suitable for, and under terms that permit, the user to
+ recombine or relink the Application with a modified version of
+ the Linked Version to produce a modified Combined Work, in the
+ manner specified by section 6 of the GNU GPL for conveying
+ Corresponding Source.
+
+ 1) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (a) uses at run time
+ a copy of the Library already present on the user's computer
+ system, and (b) will operate properly with a modified version
+ of the Library that is interface-compatible with the Linked
+ Version.
+
+ e) Provide Installation Information, but only if you would otherwise
+ be required to provide such information under section 6 of the
+ GNU GPL, and only to the extent that such information is
+ necessary to install and execute a modified version of the
+ Combined Work produced by recombining or relinking the
+ Application with a modified version of the Linked Version. (If
+ you use option 4d0, the Installation Information must accompany
+ the Minimal Corresponding Source and Corresponding Application
+ Code. If you use option 4d1, you must provide the Installation
+ Information in the manner specified by section 6 of the GNU GPL
+ for conveying Corresponding Source.)
+
+ 5. Combined Libraries.
+
+ You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+ a) Accompany the combined library with a copy of the same work based
+ on the Library, uncombined with any other library facilities,
+ conveyed under the terms of this License.
+
+ b) Give prominent notice with the combined library that part of it
+ is a work based on the Library, and explaining where to find the
+ accompanying uncombined form of the same work.
+
+ 6. Revised Versions of the GNU Lesser General Public License.
+
+ The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+ If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+Installing dvipng
+*****************
+
+Installing dvipng should be simple: merely './configure', 'make', and
+'make install'.
+
+Prerequisites
+=============
+
+ * The GD Graphics Draw library, libgd
+
+ The drawing library 'libgd' is necessary, and is downloadable at
+ <https://bitbucket.org/libgd/gd-libgd/downloads>, and there are
+ binary packages for most operating systems from their respective
+ distributors. In any case, the library installs using 'autoconf'
+ so it should not be difficult for you to install it from source,
+ and then proceed with installing dvipng.
+
+ * The path-searching library kpathsea
+
+ Kpathsea is most likely included in your LaTeX installation, but it
+ may happen that ./configure does not find it; see below. If you do
+ not have it, download it from <http://www.ctan.org> and compile it.
+ I have no experience with this, so I cannot help much here.
+
+ * The font-rendering library FreeType 2
+
+ While not strictly necessary, a recent FreeType 2 is recommended
+ since dvipng currently will produce better-quality images when this
+ library is available. To take advantage of this, you should have
+ at least FreeType 2.1.9.
+
+ FreeType 2 will enable direct support for PostScript and TrueType
+ fonts, so that dvipng will not need to generate bitmapped variants
+ on disk of the TeX fonts since modern TeX distributions include
+ PostScript versions of them. Then, you can render images at
+ different (and unusual) resolutions without cluttering the disk
+ with lots of bitmapped fonts.
+
+ Finally, it will enable subfont support in dvipng. That is, if you
+ want to render CJK-LaTeX characters, you must have FreeType 2
+ installed.
+
+ * libpng and libz
+
+ To be able to compress and write PNG files to disk, dvipng (or
+ really libgd) uses libpng which in turn uses libz. These should be
+ available on any modern system, if not, download them and install
+ them.
+
+ * The 'texinfo' package
+
+ This is needed for building the documentation.
+
+Configure
+=========
+
+The first step is to configure the source code, telling it where various
+files will be. To do so, run
+
+ ./configure OPTIONS
+
+ (Note: if you have fetched dvipng from CVS rather than a regular
+release, you will have to first generate './configure' by running
+'autoconf' 2.53 or later.)
+
+ On many machines, you will not need to specify any options, but if
+'configure' cannot determine something on its own, you'll need to help
+it out. For a list of the options type
+
+ ./configure --help
+
+ On some machines, the libraries will be installed in directories that
+are not in the linker's search path. This will generate an error when
+running './configure', indicating that it cannot find libgd or
+libkpathsea (most likely). You then need to specify the path to the
+respective library's object files. They are typically called e.g.,
+'libgd.a' or 'libgd.so'. If they are located in e.g., '/sw/local/lib',
+do
+
+ ./configure LDFLAGS=-L/sw/local/lib
+
+ If the library is available as a shared object file ('.so'), the
+runtime linker may also need to be told where to find the library, then
+use
+
+ ./configure LDFLAGS='-L/sw/local/lib -R/sw/local/lib'
+
+ When either of these is necessary, it is likely that the C header
+files are also installed in directories that are not in the C
+preprocessor's search path. This will also generate an error when
+running './configure', indicating that it cannot find e.g., 'gd.h' or
+'kpathsea.h' (most likely). You then need to specify the path to the
+respective library's C header files. If they are located in e.g.,
+'/sw/local/include', do
+
+ ./configure CPPFLAGS=-I/sw/local/include
+
+ On my SUN Solaris workstation, I had to combine this into
+
+ ./configure CPPFLAGS='-I/sw/local/include -I/sw/tex/teTeX/1.0/include'\
+ LDFLAGS='-L/sw/local/lib -R/sw/local/lib -L/sw/tex/teTeX/1.0/lib/'
+
+where the backslash denotes a continuation of the line.
+
+Build/install
+=============
+
+Once 'configure' has been run, simply enter
+
+ make
+
+at the prompt to compile the C code, and build the documentation files.
+To install the files into the locations chosen earlier, type
+
+ make install
+
+You may need special privileges to install, e.g., if you are installing
+into system directories.
+
+Installation outside the texmf tree
+===================================
+
+In some cases, a dvipng binary installed outside the texmf tree will not
+be able to find virtual fonts, or the PostScript font maps (normally
+used by dvips). This may be because _only_ $SELFAUTOLOC, $SELFAUTODIR,
+and $SELFAUTOPARENT are used in the texmf tree configuration file
+'texmf.cnf'. If so, give the switch '--enable-selfauto-set' to
+'./configure'. This will make dvipng adjust these three internally so
+that kpathsea thinks that dvipng _is_ installed in the texmf tree.
+
+Installation for non-privileged users
+=====================================
+
+Often people without system administration privileges want to install
+software for their private use. In that case you need to specify more
+options to the 'configure' script, usually this is done by using the
+'--prefix' option to the 'configure' script, and let it point to the
+personal home directory. In that way, resulting binaries will be
+installed under the 'bin' subdirectory of your home directory, manual
+pages under 'man' and so on. That way, it is reasonably easy to
+maintain a bunch of additional packages, since the prefix argument is
+supported by most 'configure' scripts.
+
+ You'll have to add something like '/home/myself/bin' to your 'PATH'
+shell variable, if it isn't there already, and similarly set the
+'INFOPATH' and 'MANPATH' variables to be able to access the
+documentation.

+dvipng
+******
+
+This program makes PNG and/or GIF graphics from DVI files as obtained
+from TeX and its relatives.
+
+ If GIF support is enabled, GIF output is chosen by using the 'dvigif'
+binary or with the '--gif' option.
+
+ It is intended to produce anti-aliased screen-resolution images as
+fast as is possible. The target audience is people who need to generate
+and regenerate many images again and again. The primary target is the
+preview-latex (X)Emacs package, a package to preview formulas from
+within (X)Emacs. Yes, you get to see your formulas in the (X)Emacs
+buffer, see <http://www.gnu.org/software/auctex/preview-latex.html>.
+
+ Another example is WeBWorK, an internet-based method for delivering
+homework problems to students over the internet, giving students instant
+feedback as to whether or not their answers are correct, see
+<http://webwork.math.rochester.edu>.
+
+ A more recent addition to the dvipng-using applications out there is
+MediaWiki, the software behind Wikipedia and many other wikis out there.
+Dvipng is used to render mathematical formulae from version 1.8.0 of
+MediaWiki, see <http://www.mediawiki.org>.
+
+ Other applications may also benefit, like web applications as
+latex2html and WYSIWYG editors like LyX.
+
+Benefits of dvipng
+==================
+
+The benefits of 'dvipng'/'dvigif' include
+
+ * Speed. It is a very fast bitmap-rendering code for DVI files,
+ which makes it suitable for generating large amounts of images
+ on-the-fly, as needed in preview-latex, WeBWorK and others.
+
+ * It does not read the postamble, so it can be started before TeX
+ finishes. There is a '--follow' switch that makes dvipng wait at
+ end-of-file for further output, unless it finds the POST marker
+ that indicates the end of the DVI.
+
+ * Interactive query of options. dvipng can read options
+ interactively through stdin, and all options are usable. It is
+ even possible to change the input file through this interface.
+
+ * Supports PK, VF, PostScript Type1, and TrueType fonts, subfonts
+ (i.e., as used in CJK-LaTeX), color specials, and inclusion of
+ PostScript, PNG, JPEG or GIF images.
+
+ * and more...
+
+Installation
+============
+
+Read 'INSTALL', included in the distribution.
+
+Usage
+=====
+
+To use dvipng at its simplest, simply type
+
+ dvipng foo
+
+where 'foo.dvi' is the output of TeX that you want to convert to PNG
+format. If there are four pages in 'foo.dvi', those pages will be
+output as 'foo1.png', 'foo2.png', 'foo3.png', and 'foo4.png',
+respectively.
+
+ Many options are available (see the info manual). For a brief
+summary of available options, just type
+
+ dvipng --help
+
+Availability
+============
+
+The dvipng package is available at Savannah, the GNU project site.
+Since dvipng is not part of the GNU project, although released under the
+GNU GPL, the web address is
+<http://savannah.nongnu.org/projects/dvipng>. Instructions for
+anonymous CVS access can be found at
+<http://savannah.nongnu.org/cvs/?group=dvipng>.
+
+Contacts
+========
+
+Bug reports should be sent to <dvipng@nongnu.org>.
+
+ Questions, suggestions for new features, pleas for help, and/or
+praise should go to <dvipng@nongnu.org>. For more information on this
+mailing list, send a message with just the word 'help' as subject or
+body to <dvipng-request@nongnu.org> or look at
+<http://lists.nongnu.org/mailman/listinfo/dvipng>.

+
+Todo
+====
+
+ * Use gs interpreter library for speed and possibly for
+ functionality.
+
+ * Add more color models for xcolor compatibility
+
+ * Enable a named pipe as DVI
+
+ * Further speed improvements.
+
+ * Other output specials and source specials.
+
+ * Clean internal structures. Overhaul file handling.
+
+ * Fix the SELFAUTO stuff at runtime rather than at build time

+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+This program makes \s-1PNG\s0 and/or \s-1GIF\s0 graphics from \s-1DVI\s0 files as obtained
+from TeX and its relatives.
+.PP
+If \s-1GIF\s0 support is enabled, \s-1GIF\s0 output is chosen by using the
+\&\fBdvigif\fR binary or with the \fB\-\-gif\fR option.
+.PP
+The benefits of \fBdvipng\fR/\fBdvigif\fR include
+.IP "*" 4
+Speed. It is a very fast bitmap-rendering code for \s-1DVI\s0 files, which
+makes it suitable for generating large amounts of images on-the-fly,
+as needed in preview-latex, WeBWorK and others.
+.IP "*" 4
+It does not read the postamble, so it can be started before TeX
+finishes. There is a \fB\-\-follow\fR switch that makes dvipng wait at
+end-of-file for further output, unless it finds the \s-1POST\s0 marker that
+indicates the end of the \s-1DVI.\s0
+.IP "*" 4
+Interactive query of options. dvipng can read options interactively
+through stdin, and all options are usable. It is even possible to change
+the input file through this interface.
+.IP "*" 4
+Supports \s-1PK, VF,\s0 PostScript Type1, and TrueType fonts, subfonts (i.e.,
+as used in CJK-LaTeX), color specials, and inclusion of PostScript,
+\&\s-1PNG, JPEG\s0 or \s-1GIF\s0 images.
+.IP "*" 4
+and more...
+.SH "OPTIONS"
+.IX Header "OPTIONS"
+Many of the parameterless options listed here can be turned off by
+suffixing the option with a zero (\fB0\fR); for instance, to turn off
+page reversal, use \fB\-r0\fR. Such options are marked with a trailing
+\&\fB*\fR.
+.IP "\fB\-\fR" 4
+.IX Item "-"
+Read additional options from standard input after processing the command
+line.
+.IP "\fB\-\-help\fR" 4
+.IX Item "--help"
+Print a usage message and exit.
+.IP "\fB\-\-version\fR" 4
+.IX Item "--version"
+Print the version number and exit.
+.IP "\fB\-bd\fR \fInum\fR" 4
+.IX Item "-bd num"
+.PD 0
+.IP "\fB\-bd\fR \fIcolor_spec\fR" 4
+.IX Item "-bd color_spec"
+.IP "\fB\-bd '\fR\fInum\fR\fB \fR\fIcolor_spec\fR\fB'\fR" 4
+.IX Item "-bd 'num color_spec'"
+.PD
+Set the pixel width of the transparent border (default 0). Using this
+option will make the image edges transparent, but it only affects pixels
+with the background color. Giving a \fIcolor_spec\fR will set the
+fallback color, to be used in viewers that cannot handle transparency
+(the default is the background color). The color spec should be in
+TeX color \especial syntax, e.g., 'rgb 1.0 0.0 0.0'. Setting the
+fallback color makes the default border width 1 px.
+.IP "\fB\-\-bdpi\fR \fInum\fR" 4
+.IX Item "--bdpi num"
+This option only has an effect when using bitmapped (\s-1PK\s0) fonts. The
+option sets the base (Metafont) resolution, both horizontal and
+vertical, to \fInum\fR dpi (dots per inch). This option is necessary
+when manually selecting Metafont mode with the \-\-mode option (see
+below).
+.IP "\fB\-bg\fR \fIcolor_spec\fR" 4
+.IX Item "-bg color_spec"
+Choose background color for the images. This option will be ignored if
+there is a background color \especial in the \s-1DVI.\s0 The color spec should
+be in TeX color \especial syntax, e.g., 'rgb 1.0 0.0 0.0'. You can
+also specify 'Transparent' or 'transparent' which will give you a
+transparent background with the normal background as a fallback color. A
+capitalized 'Transparent' will give a full-alpha transparency, while an
+all-lowercase 'transparent' will give a simple fully transparent
+background with non-transparent antialiased pixels. The latter would be
+suitable for viewers who cannot cope with a true alpha channel. \s-1GIF\s0
+images do not support full alpha transparency, so in case of \s-1GIF\s0 output,
+both variants will use the latter behaviour.
+.IP "\fB\-d\fR \fInum\fR" 4
+.IX Item "-d num"
+Set the debug flags, showing what dvipng (thinks it) is doing. This will
+work unless dvipng has been compiled without the \f(CW\*(C`DEBUG\*(C'\fR option
+(not recommended). Set the flags as you need them, use \fB\-d \-1\fR as
+the first option for maximum output.
+.IP "\fB\-D\fR \fInum\fR" 4
+.IX Item "-D num"
+Set the output resolution, both horizontal and vertical, to \fInum\fR
+dpi (dots per inch).
+.Sp
+One may want to adjust this to fit a certain text font size (e.g., on
+a web page), and for a text font height of \fIfont_px\fR pixels (in
+Mozilla) the correct formula is
+.Sp
+.Vb 1
+\& <dpi> = <font_px> * 72.27 / 10 [px * TeXpt/in / TeXpt]
+.Ve
+.Sp
+The last division by ten is due to the standard font height 10pt in
+your document, if you use 12pt, divide by 12. Unfortunately, some
+proprietary browsers have font height in pt (points), not pixels. You
+have to rescale that to pixels, using the screen resolution (default
+is usually 96 dpi) which means the formula is
+.Sp
+.Vb 1
+\& <font_px> = <font_pt> * 96 / 72 [pt * px/in / (pt/in)]
+.Ve
+.Sp
+On some high-res screens, the value is instead 120 dpi. Good luck!
+.IP "\fB\-\-depth*\fR" 4
+.IX Item "--depth*"
+Report the depth of the image. This only works reliably when the
+LaTeX style \fIpreview.sty\fR from preview-latex is used with
+the \fBactive\fR option. It reports the number of pixels from the
+bottom of the image to the baseline of the image. This can be used for
+vertical positioning of the image in, e.g., web documents, where one
+would use (Cascading StyleSheets 1)
+.Sp
+.Vb 1
+\& <IMG SRC="<filename.png>" STYLE="vertical\-align: \-<depth>px">
+.Ve
+.Sp
+The depth is a negative offset in this case, so the minus sign is
+necessary, and the unit is pixels (px).
+.IP "\fB\-\-dvinum*\fR" 4
+.IX Item "--dvinum*"
+Set this option to make the output page number be the TeX page
+numbers rather than the physical page number. See the \fB\-o\fR switch.
+.IP "\fB\-fg\fR \fIcolor_spec\fR" 4
+.IX Item "-fg color_spec"
+Choose foreground color for the images. This option will be ignored if
+there is a foreground color \especial in the \s-1DVI.\s0 The color spec should
+be in TeX color \especial syntax, e.g., 'rgb 1.0 0.0 0.0'.
+.IP "\fB\-\-follow*\fR" 4
+.IX Item "--follow*"
+Wait for data at end-of-file. One of the benefits of dvipng is that it
+does not read the postamble, so it can be started before TeX
+finishes. This switch makes dvipng wait at end-of-file for further
+output, unless it finds the \s-1POST\s0 marker that indicates the end of the
+\&\s-1DVI.\s0 This is similar to \fBtail \-f\fR but for DVI-to-PNG conversion.
+.IP "\fB\-\-freetype*\fR" 4
+.IX Item "--freetype*"
+Enable/disable FreeType font rendering (default on). This option is
+available if the FreeType2 font library was present at compilation time.
+If this is the case, dvipng will have direct support for PostScript
+Type1 and TrueType fonts internally, rather than using \fBgsftopk\fR
+for rendering the fonts. If you have PostScript versions of Computer
+Modern installed, there will be no need to generate bitmapped (\s-1PK\s0)
+variants on disk of these. Then, you can render images at different (and
+unusual) resolutions without cluttering the disk with lots of bitmapped
+fonts.
+One reason to disable FreeType font rendering would be to generate
+identical output on different platforms, since FreeType uses the native
+renderer and therefore can give slightly different output on each platform.
+.IP "\fB\-\-gamma\fR \fInum\fR" 4
+.IX Item "--gamma num"
+Control the interpolation of colors in the greyscale anti-aliasing
+color palette. Default value is 1.0. For 0 < \fInum\fR < 1, the
+fonts will be lighter (more like the background), and for \fInum\fR >
+1, the fonts will be darker (more like the foreground).
+.IP "\fB\-\-gif*\fR" 4
+.IX Item "--gif*"
+The images are output in the \s-1GIF\s0 format, if \s-1GIF\s0 support is enabled.
+This is the default for the \fBdvigif\fR binary, which only will be
+available when \s-1GIF\s0 support is enabled. \s-1GIF\s0 images are palette images
+(see the \fB\-\-palette\fR option) and does not support true alpha
+channels (see the \fB\-\-bg\fR option). See also the \fB\-\-png\fR
+option.
+.IP "\fB\-\-height*\fR" 4
+.IX Item "--height*"
+Report the height of the image. This only works reliably when the
+LaTeX style \fIpreview.sty\fR from preview-latex is used with
+the \fBactive\fR option. It reports the number of pixels from the top
+of the image to the baseline of the image. The total height of the
+image is obtained as the sum of the values reported from
+\&\fB\-\-height\fR and \fB\-\-depth\fR.
+.IP "\fB\-l [=]\fR\fInum\fR" 4
+.IX Item "-l [=]num"
+The last page printed will be the first one numbered \fInum\fR. Default
+is the last page in the document. If \fInum\fR is prefixed by an equals
+sign, then it (and the argument to the \fB\-p\fR option, if specified)
+is treated as a physical (absolute) page number, rather than a value to
+compare with the TeX \fB\ecount0\fR values stored in the \s-1DVI\s0 file.
+Thus, using \fB\-l =9\fR will end with the ninth page of the document,
+no matter what the pages are actually numbered.
+.IP "\fB\-\-mode\fR \fImode\fR" 4
+.IX Item "--mode mode"
+This option only has an effect when using bitmapped (\s-1PK\s0) fonts. Use
+\&\fImode\fR as the Metafont device name for the \s-1PK\s0 fonts (both for path
+searching and font generation). This needs to be augmented with the base
+device resolution, given with the \fB\-\-bdpi\fR option. See the file
+<\fBftp://ftp.tug.org/tex/modes.mf\fR> for a list of resolutions and mode
+names for most devices.
+.IP "\fB\-M*\fR" 4
+.IX Item "-M*"
+This option only has an effect when using bitmapped (\s-1PK\s0) fonts. It turns
+off automatic \s-1PK\s0 font generation (\fImktexpk\fR).
+.IP "\fB\-\-nogs*\fR" 4
+.IX Item "--nogs*"
+This switch prohibits the internal call to GhostScript for displaying
+PostScript specials. \fB\-\-nogs0\fR turns the call back on.
+.IP "\fB\-\-nogssafer*\fR" 4
+.IX Item "--nogssafer*"
+Normally, if GhostScript is used to render PostScript specials, the
+GhostScript interpreter is run with the option \fB\-dSAFER\fR. The
+\&\fB\-\-nogssafer\fR option runs GhostScript without \fB\-dSAFER\fR. The
+\&\fB\-dSAFER\fR option in Ghostscript disables PostScript operators such
+as deletefile, to prevent possibly malicious PostScript programs from
+having any effect.
+.IP "\fB\-\-norawps*\fR" 4
+.IX Item "--norawps*"
+Some packages generate raw PostScript specials, even non-rendering such
+specials. This switch turns off the internal call to GhostScript
+intended to display these raw PostScript specials. \fB\-\-norawps0\fR
+turns the call back on.
+.IP "\fB\-o\fR \fIname\fR" 4
+.IX Item "-o name"
+Send output to the file \fIname\fR. A single occurrence of \fB\f(CB%d\fB\fR or
+\&\fB\f(CB%01d\fB\fR, ..., \fB\f(CB%09d\fB\fR will be exchanged for the physical
+page number (this can be changed, see the \fB\-\-dvinum\fR switch). The
+default output filename is \fIfile\fR\fB\f(CB%d\fB.png\fR where the input \s-1DVI\s0
+file was \fIfile\fR\fB.dvi\fR.
+.IP "\fB\-O\fR \fIx\-offset\fR\fB,\fR\fIy\-offset\fR" 4
+.IX Item "-O x-offset,y-offset"
+Move the origin by \fIx\-offset\fR,\fIy\-offset\fR, a comma-separated
+pair of dimensions such as \fB.1in,\-.3cm\fR.
+The origin of the page is shifted from the default position
+(of one inch down, one inch to the right from the upper left corner of
+the paper) by this amount.
+.IP "\fB\-p [=]\fR\fInum\fR" 4
+.IX Item "-p [=]num"
+The first page printed will be the first one numbered \fInum\fR. Default
+is the first page in the document. If \fInum\fR is prefixed by an
+equals sign, then it (and the argument to the \fB\-l\fR option, if
+specified) is treated as a physical (absolute) page number, rather than
+a value to compare with the TeX \fB\ecount0\fR values stored in the
+\&\s-1DVI\s0 file. Thus, using \fB\-p =3\fR will start with the third page of
+the document, no matter what the pages are actually numbered.
+.IP "\fB\-\-palette*\fR" 4
+.IX Item "--palette*"
+When an external image is included, \fBdvipng\fR will automatically
+switch to truecolor mode, to avoid unnecessary delay and quality
+reduction, and enable the \s-1EPS\s0 translator to draw on a transparent
+background and outside of the boundingbox. This switch will force
+palette (256\-color) output and make \fBdvipng\fR revert to opaque
+clipped image inclusion. This will also override the \fB\-\-truecolor\fR
+switch if present.
+.IP "\fB\-\-picky*\fR" 4
+.IX Item "--picky*"
+No images are output when a warning occurs. Normally, dvipng will
+output an image in spite of a warning, but there may be something
+missing in this image. One reason to use this option would be if you
+have a more complete but slower fallback converter. Mainly, this is
+useful for failed figure inclusion and unknown \especial occurrences,
+but warnings will also occur for missing or unknown color specs and
+missing \s-1PK\s0 fonts.
+.IP "\fB\-\-png*\fR" 4
+.IX Item "--png*"
+The images are output in the \s-1PNG\s0 format. This is the default for the
+\&\fBdvipng\fR binary. See also the \fB\-\-gif\fR option.
+.IP "\fB\-pp\fR \fIfirstpage\fR\fB\-\fR\fIlastpage\fR" 4
+.IX Item "-pp firstpage-lastpage"
+Print pages \fIfirstpage\fR through \fIlastpage\fR; but not quite
+equivalent to \fB\-p\fR \fIfirstpage\fR \fB\-l\fR \fIlastpage\fR. For example,
+when rendering a book, there may be several instances of a page in the
+\&\s-1DVI\s0 file (one in \f(CW\*(C`\efrontmatter\*(C'\fR, one in \f(CW\*(C`\emainmatter\*(C'\fR, and one
+in \f(CW\*(C`\ebackmatter\*(C'\fR). In case of several pages matching, \fB\-pp\fR
+\&\fIfirstpage\fR\fB\-\fR\fIlastpage\fR will render \fIall\fR pages that
+matches the specified range, while \fB\-p\fR \fIfirstpage\fR \fB\-l\fR
+\&\fIlastpage\fR will render the pages from the \fIfirst\fR occurrence
+of \fIfirstpage\fR to the \fIfirst\fR occurrence of \fIlastpage\fR.
+This is the (undocumented) behaviour of dvips. In dvipng you can give
+both kinds of options, in which case you get all pages that matches the
+range in \fB\-pp\fR between the pages from \fB\-p\fR to \fB\-l\fR. Also
+multiple \fB\-pp\fR options accumulate, unlike \fB\-p\fR and \fB\-l\fR.
+The \fB\-\fR separator can also be \fB:\fR. Note that \fB\-pp \-1\fR
+will be interpreted as \*(L"all pages up to and including 1\*(R", if you want a
+page numbered \-1 (only the table of contents, say) put \fB\-pp \-1\-\-1\fR,
+or more readable, \fB\-pp \-1:\-1\fR.
+.IP "\fB\-q*\fR" 4
+.IX Item "-q*"
+Run quietly. Don't chatter about pages converted, etc. to standard
+output; report no warnings (only errors) to standard error.
+.IP "\fB\-Q\fR \fInum\fR" 4
+.IX Item "-Q num"
+Set the quality to \fInum\fR. That is, choose the number of antialiasing
+levels for bitmapped fonts (\s-1PK\s0), to be
+\&\fInum\fR*\fInum\fR+1. The default value is 4 which gives 17 levels of
+antialiasing for antialiased fonts from these two. If FreeType is
+available, its rendering is unaffected by this option.
+.IP "\fB\-r*\fR" 4
+.IX Item "-r*"
+Toggle output of pages in reverse/forward order. By default, the first
+page in the \s-1DVI\s0 is output first.
+.IP "\fB\-\-strict*\fR" 4
+.IX Item "--strict*"
+The program exits when a warning occurs. Normally, dvipng will output
+an image in spite of a warning, but there may be something missing in
+this image. One reason to use this option would be if you have a more
+complete but slower fallback converter. See the \fB\-\-picky\fR option
+above for a list of when warnings occur.
+.IP "\fB\-T\fR \fIimage_size\fR" 4
+.IX Item "-T image_size"
+Set the image size to \fIimage_size\fR which can be either of
+\&\fBbbox\fR, \fBtight\fR, or a comma-separated pair of dimensions
+\&\fIhsize\fR,\fIvsize\fR such as \fB.1in,.3cm\fR. The default is
+\&\fBbbox\fR which produces a \s-1PNG\s0 that includes all ink put on the page
+and in addition the \s-1DVI\s0 origin, located 1in from the top and 1in from
+the left edge of the paper. This usually gives whitespace above and to
+the left in the produced image. The value \fBtight\fR will make dvipng
+only include all ink put on the page, producing neat images.
+.IP "\fB\-\-truecolor*\fR" 4
+.IX Item "--truecolor*"
+This will make \fBdvipng\fR generate truecolor output. Note that
+truecolor output is automatic if you include an external image in your
+\&\s-1DVI,\s0 e.g., via a PostScript special (i.e., the \fBgraphics\fR or
+\&\fBgraphicx\fR package). This switch is overridden by the
+\&\fB\-\-palette\fR switch.
+.IP "\fB\-v*\fR" 4
+.IX Item "-v*"
+Enable verbose operation. This will currently indicate what fonts is
+used, in addition to the usual output.
+.IP "\fB\-\-width*\fR" 4
+.IX Item "--width*"
+Report the width of the image. See also \fB\-\-height\fR and
+\&\fB\-\-depth\fR.
+.IP "\fB\-x\fR \fInum\fR" 4
+.IX Item "-x num"
+This option is deprecated; it should not be used. It is much better to
+select the output resolution directly with the \fB\-D\fR option. This
+option sets the magnification ratio to \fInum\fR/1000 and
+overrides the magnification specified in the \s-1DVI\s0 file. Must be between
+10 and 100000. It is recommended that you use standard magstep values
+(1095, 1200, 1440, 1728, 2074, 2488, 2986, and so on) to help reduce the
+total number of \s-1PK\s0 files generated. \fInum\fR may be a real number, not
+an integer, for increased precision.
+.IP "\fB\-z\fR \fInum\fR" 4
+.IX Item "-z num"
+Set the \s-1PNG\s0 compression level to \fInum\fR. This option is enabled if
+your \fBlibgd\fR is new enough. The default compression level is 1,
+which selects maximum speed at the price of slightly larger PNGs. For an
+older \fBlibgd\fR, the hard-soldered value 5 is used. The include file
+\&\fBpng.h\fR says
+\&\*(L"Currently, valid values range from 0 \- 9, corresponding directly to
+the zlib compression levels 0 \- 9 (0 \- no compression, 9 \- \*(R"maximal\*(L"
+compression). Note that tests have shown that zlib compression levels
+3\-6 usually perform as well as level 9 for \s-1PNG\s0 images, and do
+considerably fewer calculations. In the future, these values may not
+correspond directly to the zlib compression levels.\*(R"

+
+@node Basic usage
+@chapter Basic usage of dvipng
+
+@cindex invoking dvipng
+
+To use dvipng at its simplest, simply type
+
+@example
+dvipng foo
+@end example
+
+@noindent
+where @file{foo.dvi} is the output of @TeX{} that you want to convert to
+PNG format. If there are four pages in @file{foo.dvi}, those pages will
+be output as @file{foo1.png}, @file{foo2.png}, @file{foo3.png}, and
+@file{foo4.png}, respectively.
+
+If you have enabled the PostScript font support (via FreeType),
+fonts will be rendered as they are needed. Otherwise, dvipng will use
+bitmapped (PK) fonts, and if you use PK fonts that have not been used on
+your system before, they may be automatically generated; this process
+can take a few minutes, so progress reports appear by default. The next
+time the same font is used, it will have been saved on disk, so
+rendering will go much faster. (If dvipng tries to endlessly generate
+the same fonts over and over again, something is wrong. @xref{Unable to
+generate fonts,,, kpathsea, Kpathsea}.)
+
+Many options are available (see the next section). For a brief summary
+of available options, just type
+
+@example
+dvipng --help
+@end example
+
+@node Command-line options

+
+Many of the parameterless options listed here can be turned off by
+suffixing the option with a zero (@samp{0}); for instance, to turn off
+page reversal, use @samp{-r0}. Such options are marked with a trailing
+@samp{*}.
+
+@table @samp
+@item -
+@cindex options, reading from standard input
+@cindex standard input, reading options from
+Read additional options from standard input after processing the command
+line.
+
+@item --help
+Print a usage message and exit.
+
+@item --version
+Print the version number and exit.
+
+@item -bd @var{num}
+@item -bd @var{color_spec}
+@item -bd '@var{num} @var{color_spec}'
+@cindex transparent border width
+@cindex transparent border fallback color
+Set the pixel width of the transparent border (default 0). Using this
+option will make the image edges transparent, but it only affects pixels
+with the background color. Giving a @var{color_spec} will set the
+fallback color, to be used in viewers that cannot handle transparency
+(the default is the background color). The color spec should be in
+@TeX{} color \special syntax, e.g., 'rgb 1.0 0.0 0.0'. Setting the
+fallback color makes the default border width 1 px. @xref{Color}.
+
+@item --bdpi @var{num}
+@cindex base resolution, setting
+This option only has an effect when using bitmapped (PK) fonts. The
+option sets the base (Metafont) resolution, both horizontal and
+vertical, to @var{num} dpi (dots per inch). This option is necessary
+when manually selecting Metafont mode with the --mode option (see
+below).
+
+@item -bg @var{color_spec}
+@cindex background color (option)
+Choose background color for the images. This option will be ignored if
+there is a background color \special in the DVI. The color spec should
+be in @TeX{} color \special syntax, e.g., 'rgb 1.0 0.0 0.0'. You can
+also specify 'Transparent' or 'transparent' which will give you a
+transparent background with the normal background as a fallback color. A
+capitalized 'Transparent' will give a full-alpha transparency, while an
+all-lowercase 'transparent' will give a simple fully transparent
+background with non-transparent antialiased pixels. The latter would be
+suitable for viewers who cannot cope with a true alpha channel. GIF
+images do not support full alpha transparency, so in case of GIF output,
+both variants will use the latter behaviour. @xref{Color}.
+
+@item -d @var{num}
+@cindex debugging
+Set the debug flags, showing what dvipng (thinks it) is doing. This will
+work unless dvipng has been compiled without the @code{DEBUG} option
+(not recommended). Set the flags as you need them, use @samp{-d -1} as
+the first option for maximum output. @xref{Debug options}.
+
+@item -D @var{num}
+@cindex output resolution, setting
+Set the output resolution, both horizontal and vertical, to @var{num}
+dpi (dots per inch).
+
+One may want to adjust this to fit a certain text font size (e.g., on
+a web page), and for a text font height of @var{font_px} pixels (in
+Mozilla) the correct formula is
+@example
+@var{dpi} = @var{font_px} * 72.27 / 10 [px * @TeX{}pt/in / @TeX{}pt]
+@end example
+The last division by ten is due to the standard font height 10pt in
+your document, if you use 12pt, divide by 12. Unfortunately, some
+proprietary browsers have font height in pt (points), not pixels. You
+have to rescale that to pixels, using the screen resolution (default
+is usually 96 dpi) which means the formula is
+@example
+@var{font_px} = @var{font_pt} * 96 / 72 [pt * px/in / (pt/in)]
+@end example
+On some high-res screens, the value is instead 120 dpi. Good luck!
+
+@item --depth*
+@cindex baseline reporting
+@cindex depth reporting
+Report the depth of the image. This only works reliably when the
+@LaTeX{} style @file{preview.sty} from @previewlatex{} is used with
+the @samp{active} option. It reports the number of pixels from the
+bottom of the image to the baseline of the image. This can be used for
+vertical positioning of the image in, e.g., web documents, where one
+would use (Cascading StyleSheets 1)
+@example
+<IMG SRC="@var{filename.png}" STYLE="vertical-align: -@var{depth}px">
+@end example
+The depth is a negative offset in this case, so the minus sign is
+necessary, and the unit is pixels (px).
+
+@item --dvinum*
+Set this option to make the output page number be the @TeX{} page
+numbers rather than the physical page number. See the @samp{-o} switch.
+
+@ignore
+@item -e @var{num}
+@cindex maxdrift
+@cindex accuracy in positioning
+@cindex positioning accuracy
+Maximum drift in pixels of each character from its `true'
+resolution-independent position on the page. The default value of this
+parameter is resolution dependent (it is the number of entries in the
+list [100, 200, 300, 400, 500, 600, 800, 1000, 1200, 1600, 2000, 2400,
+2800, 3200, @dots{}] that are less than or equal to the resolution in
+dots per inch). Allowing individual characters to `drift' from their
+correctly rounded positions by a few pixels, while regaining the true
+position at the beginning of each new word, improves the spacing of
+letters in words.
+
+@item -f*
+@cindex filter, running as a
+@cindex standard I/O
+@cindex pipes, not readable
+@vindex PRINTER@r{, avoided with @samp{-f}}
+Run as a filter. Read the DVI file from standard input and write the
+PostScript to standard output. The standard input must be seekable, so
+it cannot be a pipe. If your input must be a pipe, write a shell script
+that copies the pipe output to a temporary file and then points dvipng at
+this file. This option also disables the automatic reading of the
+@code{PRINTER} environment variable; use @samp{-P$PRINTER} after the
+@samp{-f} to read it anyway. It also turns off the automatic sending of
+control-D if it was turned on with the @samp{-F} option or in the
+configuration file; use @samp{-F} after the @samp{-f} to send it anyway.
+
+@item -k*
+@cindex cropmarks
+Print crop marks. This option increases the paper size (which should be
+specified, either with a paper size special or with the @samp{-T}
+option) by a half inch in each dimension. It translates each page by a
+quarter inch and draws cross-style crop marks. It is mostly useful with
+typesetters that can set the page size automatically. This works by
+downloading @file{crop.pro}.
+@end ignore
+
+@item -fg @var{color_spec}
+@cindex foreground color (option)
+Choose foreground color for the images. This option will be ignored if
+there is a foreground color \special in the DVI. The color spec should
+be in @TeX{} color \special syntax, e.g., 'rgb 1.0 0.0 0.0'.
+@xref{Color}.
+
+@item --follow*
+@cindex follow mode
+Wait for data at end-of-file. One of the benefits of dvipng is that it
+does not read the postamble, so it can be started before @TeX{}
+finishes. This switch makes dvipng wait at end-of-file for further
+output, unless it finds the POST marker that indicates the end of the
+DVI. This is similar to @samp{tail -f} but for DVI-to-PNG conversion.
+
+@item --freetype*
+@cindex FreeType font rendering
+Enable/disable FreeType font rendering (default on). This option is
+available if the FreeType2 font library was present at compilation time.
+If this is the case, dvipng will have direct support for PostScript
+Type1 and TrueType fonts internally, rather than using @samp{gsftopk}
+for rendering the fonts. If you have PostScript versions of Computer
+Modern installed, there will be no need to generate bitmapped (PK)
+variants on disk of these. Then, you can render images at different (and
+unusual) resolutions without cluttering the disk with lots of bitmapped
+fonts.
+One reason to disable FreeType font rendering would be to generate
+identical output on different platforms, since FreeType uses the native
+renderer and therefore can give slightly different output on each platform.
+
+@item --gamma @var{num}
+@cindex gamma
+@cindex dark fonts
+@cindex light fonts
+@cindex fuzzy images
+Control the interpolation of colors in the greyscale anti-aliasing
+color palette. Default value is 1.0. For 0 < @var{num} < 1, the
+fonts will be lighter (more like the background), and for @var{num} >
+1, the fonts will be darker (more like the foreground).
+
+@item --gif*
+@cindex GIF image format
+The images are output in the GIF format, if GIF support is enabled.
+This is the default for the @samp{dvigif} binary, which only will be
+available when GIF support is enabled. GIF images are palette images
+(see the @samp{--palette} option) and does not support true alpha
+channels (see the @samp{--bg} option). See also the @samp{--png}
+option.
+
+@item --height*
+@cindex baseline reporting
+@cindex height reporting
+Report the height of the image. This only works reliably when the
+@LaTeX{} style @file{preview.sty} from @previewlatex{} is used with
+the @samp{active} option. It reports the number of pixels from the top
+of the image to the baseline of the image. The total height of the
+image is obtained as the sum of the values reported from
+@samp{--height} and @samp{--depth}.
+
+@item -l [=]@var{num}
+@cindex last page printed
+@cindex page, last printed
+@cindex physical page number, and @samp{-l}
+@cindex absolute page number, and @samp{-l}
+The last page printed will be the first one numbered @var{num}. Default
+is the last page in the document. If @var{num} is prefixed by an equals
+sign, then it (and the argument to the @samp{-p} option, if specified)
+is treated as a physical (absolute) page number, rather than a value to
+compare with the @TeX{} @samp{\count0} values stored in the DVI file.
+Thus, using @samp{-l =9} will end with the ninth page of the document,
+no matter what the pages are actually numbered.
+
+@item --mode @var{mode}
+@cindex mode name, specifying
+@cindex Metafont mode, specifying
+This option only has an effect when using bitmapped (PK) fonts. Use
+@var{mode} as the Metafont device name for the PK fonts (both for path
+searching and font generation). This needs to be augmented with the base
+device resolution, given with the @samp{--bdpi} option. See the file
+@url{ftp://ftp.tug.org/tex/modes.mf} for a list of resolutions and mode
+names for most devices. @xref{Unable to generate fonts,,, kpathsea,
+Kpathsea}.
+
+@item -M*
+@cindex font generation, avoiding
+@pindex mktexpk@r{, avoiding}
+@c this description repeated in kpathsea.texi
+This option only has an effect when using bitmapped (PK) fonts. It turns
+off automatic PK font generation (@file{mktexpk}).
+@ignore
+@flindex missfont.log
+If @code{mktexpk}, the invocation is appended to a file
+@file{missfont.log} (by default) in the current directory. You can then
+execute the log file to create the missing files after fixing the
+problem.
+@vindex TEXMFOUTPUT
+@vindex MISSFONT_LOG
+If the current directory is not writable and the environment variable or
+configuration file value @samp{TEXMFOUTPUT} is set, its value is used.
+Otherwise, nothing is written. The name @samp{missfont.log} is
+overridden by the @samp{MISSFONT_LOG} environment variable or
+configuration file value.
+@end ignore
+
+@item --nogs*
+@cindex GhostScript, turning off
+This switch prohibits the internal call to GhostScript for displaying
+PostScript specials. @samp{--nogs0} turns the call back on.
+
+@item --nogssafer*
+@cindex GhostScript and -dSAFER
+@cindex -dSAFER
+Normally, if GhostScript is used to render PostScript specials, the
+GhostScript interpreter is run with the option @samp{-dSAFER}. The
+@samp{--nogssafer} option runs GhostScript without @samp{-dSAFER}. The
+@samp{-dSAFER} option in Ghostscript disables PostScript operators such
+as deletefile, to prevent possibly malicious PostScript programs from
+having any effect.
+
+@item --norawps*
+@cindex PostScript, turning off raw PostScript specials
+Some packages generate raw PostScript specials, even non-rendering such
+specials. This switch turns off the internal call to GhostScript
+intended to display these raw PostScript specials. @samp{--norawps0}
+turns the call back on.
+
+@item -o @var{name}
+@cindex output, redirecting
+@cindex standard output, output to
+Send output to the file @var{name}. A single occurrence of @samp{%d} or
+@samp{%01d}, @dots{}, @samp{%09d} will be exchanged for the physical
+page number (this can be changed, see the @samp{--dvinum} switch). The
+default output filename is @samp{@var{file}%d.png} where the input DVI
+file was @samp{@var{file}.dvi}.
+
+@item -O @var{x-offset},@var{y-offset}
+@cindex offset pages
+Move the origin by @var{x-offset},@var{y-offset}, a comma-separated
+pair of dimensions such as @samp{.1in,-.3cm}.
+@c (@pxref{papersize special}).
+The origin of the page is shifted from the default position
+(of one inch down, one inch to the right from the upper left corner of
+the paper) by this amount.
+
+@item -p [=]@var{num}
+@cindex first page printed
+@cindex page, first printed
+@cindex physical page number, and @samp{-p}
+@cindex absolute page number, and @samp{-p}
+The first page printed will be the first one numbered @var{num}. Default
+is the first page in the document. If @var{num} is prefixed by an
+equals sign, then it (and the argument to the @samp{-l} option, if
+specified) is treated as a physical (absolute) page number, rather than
+a value to compare with the @TeX{} @samp{\count0} values stored in the
+DVI file. Thus, using @samp{-p =3} will start with the third page of
+the document, no matter what the pages are actually numbered.
+
+@item --palette*
+@cindex forcing palette output
+When an external image is included, @samp{dvipng} will automatically
+switch to truecolor mode, to avoid unnecessary delay and quality
+reduction, and enable the EPS translator to draw on a transparent
+background and outside of the boundingbox. This switch will force
+palette (256-color) output and make @samp{dvipng} revert to opaque
+clipped image inclusion. This will also override the @samp{--truecolor}
+switch if present.
+
+@item --picky*
+@cindex no erroneous images
+No images are output when a warning occurs. Normally, dvipng will
+output an image in spite of a warning, but there may be something
+missing in this image. One reason to use this option would be if you
+have a more complete but slower fallback converter. Mainly, this is
+useful for failed figure inclusion and unknown \special occurrences,
+but warnings will also occur for missing or unknown color specs and
+missing PK fonts.
+
+@item --png*
+@cindex PNG image format
+The images are output in the PNG format. This is the default for the
+@samp{dvipng} binary. See also the @samp{--gif} option.
+
+@item -pp @var{firstpage}-@var{lastpage}
+@cindex page range
+Print pages @var{firstpage} through @var{lastpage}; but not quite
+equivalent to @samp{-p @var{firstpage} -l @var{lastpage}}. For example,
+when rendering a book, there may be several instances of a page in the
+DVI file (one in @code{\frontmatter}, one in @code{\mainmatter}, and one
+in @code{\backmatter}). In case of several pages matching, @samp{-pp
+@var{firstpage}-@var{lastpage}} will render @emph{all} pages that
+matches the specified range, while @samp{-p @var{firstpage} -l
+@var{lastpage}} will render the pages from the @emph{first} occurrence
+of @var{firstpage} to the @emph{first} occurrence of @var{lastpage}.
+This is the (undocumented) behaviour of dvips. In dvipng you can give
+both kinds of options, in which case you get all pages that matches the
+range in @samp{-pp} between the pages from @samp{-p} to @samp{-l}. Also
+multiple @samp{-pp} options accumulate, unlike @samp{-p} and @samp{-l}.
+The @samp{-} separator can also be @samp{:}. Note that @samp{-pp -1}
+will be interpreted as "all pages up to and including 1", if you want a
+page numbered -1 (only the table of contents, say) put @samp{-pp -1--1},
+or more readable, @samp{-pp -1:-1}.

+@chapter Graphics
+
+@samp{dvipng} attempts to handle graphics as included by the
+@samp{graphicx} and @samp{graphics} packages, without the need of
+specifying a driver to these packages. This means that it recognizes
+the encapsulated postscript inclusion meant for @samp{dvips}, but is
+also able (from version 1.8) to include bitmapped graphics. It also
+tries to handle some of the raw PostScript that is output from various
+packages. Some of the possibilities and problems are mentioned below.
+
+@menu
+* Encapsulated PostScript:: An internal call to GhostScript
+* Bitmapped graphics:: PNG, JPEG and GIF
+* Raw PostScript:: Ignore or give to GhostScript
+@end menu
+
+@node Encapsulated PostScript
+@section Encapsulated PostScript
+
+When an EPS file is included, a call to GhostScript is performed to
+produce a bitmapped image that can be included. The default is to
+produce an image with transparent background, at the same size as the
+DVI page currently being converted to PNG, and include that as
+foreground on the PNG. Of course, if the image is to be cropped, that
+is done. The included image will be a truecolor image, so for maximum
+performance the output PNG will be in truecolor mode as well.
+
+This conversion needs the @samp{pngalpha} output device to be present
+in your copy of GhostScript. If that device is not present, or you use
+the @samp{--palette} switch or request GIF output, the fallback is to
+use the @samp{png16m} device to produce a cropped opaque image for
+inclusion. Other relevant switches are @samp{--noghostscript} and
+@samp{--nogssafer}. @xref{Option details}.
+
+@cindex PostScript inclusion problems
+The most common problem with including graphics is an incorrect
+bounding box. Complain to whoever wrote the software that generated
+the file if the bounding box is indeed incorrect. An adjusted
+boundingbox can be specified in the @samp{\includegraphics} call, as
+in this example (using @samp{graphicx}):
+
+@example
+\includegraphics[bb=10 20 100 200]@{imagename.eps@}
+@end example
+
+
+@node Bitmapped graphics
+@section Bitmapped graphics
+
+dvipng can include PNG, JPEG and GIF graphics. When including such
+images via @samp{\includegraphics} you need to specify the bounding
+box since @TeX{} itself cannot read them from the files in question.
+The bounding box size should be given as @samp{0 0 w h} in pixels,
+e.g., if the file @samp{imagename.png} is 300x400 pixels, the
+inclusion would read
+
+@example
+\includegraphics[bb=0 0 300 400]@{imagename.png@}
+@end example
+
+The default size is the image size in bp (``big points'' in TeX
+nomenclature or PostScript points as other people have it, 72 per inch).
+That is, default resolution will be 72 dpi for included bitmaps, which
+is the default size in the few other bitmap-capable drivers that are
+known to me (dvipdfm and PDFLaTeX).
+
+If you want 100 dpi you need to specify the width accordingly. You
+just divide your image width by 100: a 135 pixel wide image at 100 dpi
+will take up 1.35 inches. If you want 200 dpi you divide by 200, and
+so on. Simple, eh? The example above at 200 dpi would be 1.5 inches
+wide:
+
+@example
+\includegraphics[bb=0 0 300 400,witdh=1.5in]@{imagename.png@}
+@end example
+
+@node Raw PostScript
+@section Raw PostScript
+
+dvipng attempts to handle raw PostScript. Rendering raw PostScript
+specials is done on top of the page by including a transparent image
+generated by the @samp{pngalpha} device in GhostScript (automatically
+selecting @samp{truecolor} mode in dvipng).
+
+Included PostScript headers are respected, and if the header
+@samp{tex.pro} is included, dvipng also throws in @samp{color.pro} and
+@samp{special.pro}. The package @samp{xcolor} includes its own headers
+with color names, and this is not only kept as a PostScript header, but
+is also read and interpreted by dvipng itself. An attempt is also made
+to respect the PGF header. The non-rendering specials from
+@samp{hyperref} are handled via some heuristics and do not give an
+error.
+
+Really rendering and moving things with raw PostScript specials is more
+troublesome. The \rotatebox macro serves as a good example. The dvips
+driver of the graphicx package surrounds DVI glyphs with PostScript code
+so that after conversion by dvips, the glyphs (now themselves in
+PostScript) will be rotated in the desired way. dvipng does not handle
+this, at present. An attempt has been made to handle the rendering
+specials output by PGF (tikz), and also PSTricks. Some things work, but
+others do not. This is especially clear when mixing PostScript and DVI
+rendering commands such as glyphs. dvipng cannot at present detect if
+PostScript code moves @samp{currentpoint} or rotates the frame since
+GhostScript does not return such information. A recommendation would be
+to produce images from these packages as EPS files and include them into
+your document in the standard manner.
+
+Another way to handle this would be to use a slower fallback (with dvips
+and gs, for example). If you want to disable raw PostScript handling in
+dvipng, use the switch @samp{--norawps}. This switch turns off the
+internal call to GhostScript intended to display these raw PostScript
+specials. Further, when dvipng encounters raw PostScript and the gs call
+is turned off, it gives a warning. It is now possible to use the switch
+@samp{--picky} to disable page rendering of pages with warnings, and use
+the slower fallback for these pages.
+
+@node Color
+@chapter Color
+
+To support color, dvipng recognizes a certain set of specials as
+generated by the @samp{color} and @samp{xcolor} style files. These
+specials start with the keyword @samp{color} or the keyword
+@samp{background}, followed by a color specification.
+
+@menu
+* Color specifications::
+* Color specials::
+@end menu
+
+
+@node Color specifications
+@section Color specifications
+
+@cindex color specifications
+
+The color specification supported by dvipng is by-value or by-name. The
+by-value spec starts with the name of a color model (one of @samp{rgb},
+@samp{hsb}, @samp{cmy}, @samp{cmyk}, or @samp{gray}) followed by the
+appropriate number of parameters. Thus, the color specification
+@samp{rgb 0.3 0.4 0.5} would correspond to the color that is @samp{0.3
+0.4 0.5} in its red, blue and green values. The color model used
+internally in dvipng is @samp{RGB} (discretized to 256 levels), for
+details on the formulas used in conversion, see the @samp{xcolor}
+documentation.
+
+By-name color specifications are single (case-dependent) words and are
+compared with color names defined in @samp{dvipsnam.def} (from the
+@samp{graphics} bundle), @samp{svgnam.def} and @samp{xcolor.sty} (from
+the @samp{xcolor} bundle). See the @samp{xcolor} documentation for a
+list of names and the corresponding colors.
+
+On the command-line, the name @samp{Transparent} can also be used as
+an argument to @samp{--bg} to choose transparent background.
+@xref{Option details}.
+
+@node Color specials
+@section Color specials
+
+We will describe @samp{background} first, since it is the simplest. The
+@samp{background} keyword must be followed by a color specification.
+That color specification is used as a fill color for the background. The
+last @samp{background} special on a page is the one that gets used, and
+is used for the whole of the page image. (This is possible because the
+prescan phase of dvipng notices all of the color specials so that the
+appropriate information can be written out during the second phase.)
+
+The @samp{color} special itself has three forms. The first is just
+@samp{color} followed by a color specification. In this case, the
+current global color is set to that color; the color stack must be empty
+when such a command is executed.
+
+The second form is @samp{color push} followed by a color specification.
+This saves the current color on the color stack and sets the color to be
+that given by the color specification. This is the most common way to
+set a color.
+
+The final form of the @samp{color} special is just @samp{color pop},
+with no color specification; this says to pop the color last pushed on
+the color stack from the color stack and set the current color to be
+that color.
+
+dvipng correctly handles these color specials across pages, even when
+the pages are rendered repeatedly or in reverse order.

+
+@end ifset
+@c -----------------------
+Installing dvipng should be simple: merely @code{./configure},
+@code{make}, and @code{make install}.

+
+@node Prerequisites
+@section Prerequisites
+
+@itemize @bullet
+@item The GD Graphics Draw library, libgd
+
+The drawing library @samp{libgd} is necessary, and is downloadable at
+@uref{https://bitbucket.org/libgd/gd-libgd/downloads}, and there are
+binary packages for most operating systems from their respective
+distributors. In any case, the library installs using @samp{autoconf} so
+it should not be difficult for you to install it from source, and then
+proceed with installing dvipng.
+
+@item The path-searching library kpathsea
+
+Kpathsea is most likely included in your @LaTeX{} installation, but it
+may happen that ./configure does not find it; see below. If you do not
+have it, download it from @uref{http://www.ctan.org} and compile it.
+I have no experience with this, so I cannot help much here.
+
+@item The font-rendering library FreeType 2
+
+While not strictly necessary, a recent FreeType 2 is recommended since
+dvipng currently will produce better-quality images when this library is
+available. To take advantage of this, you should have at least FreeType
+2.1.9.
+
+FreeType 2 will enable direct support for PostScript and TrueType fonts,
+so that dvipng will not need to generate bitmapped variants on disk of
+the @TeX{} fonts since modern @TeX{} distributions include PostScript
+versions of them. Then, you can render images at different (and unusual)
+resolutions without cluttering the disk with lots of bitmapped fonts.
+
+Finally, it will enable subfont support in dvipng. That is, if you want
+to render CJK-@LaTeX{} characters, you must have FreeType 2 installed.
+
+@item libpng and libz
+
+To be able to compress and write PNG files to disk, dvipng (or really
+libgd) uses libpng which in turn uses libz. These should be available on
+any modern system, if not, download them and install them.
+
+@item The @code{texinfo} package
+
+This is needed for building the documentation.
+@end itemize
+
+@node Configure
+@section Configure
+
+The first step is to configure the source code, telling it where
+various files will be. To do so, run
+
+@example
+./configure @var{options}
+@end example
+
+(Note: if you have fetched dvipng from CVS rather than a regular
+release, you will have to first generate @file{./configure} by running
+@code{autoconf} 2.53 or later.)
+
+On many machines, you will not need to specify any options, but if
+@code{configure} cannot determine something on its own, you'll need to
+help it out. For a list of the options type
+
+@example
+./configure --help
+@end example
+
+On some machines, the libraries will be installed in directories that
+are not in the linker's search path. This will generate an error when
+running @file{./configure}, indicating that it cannot find libgd or
+libkpathsea (most likely). You then need to specify the path to the
+respective library's object files. They are typically called e.g.,
+@file{libgd.a} or @file{libgd.so}. If they are located in e.g.,
+@file{/sw/local/lib}, do
+
+@example
+./configure LDFLAGS=-L/sw/local/lib
+@end example
+
+If the library is available as a shared object file (@file{.so}), the
+runtime linker may also need to be told where to find the library,
+then use
+
+@example
+./configure LDFLAGS='-L/sw/local/lib -R/sw/local/lib'
+@end example
+
+When either of these is necessary, it is likely that the C header
+files are also installed in directories that are not in the C
+preprocessor's search path. This will also generate an error when
+running @file{./configure}, indicating that it cannot find e.g.,
+@file{gd.h} or @file{kpathsea.h} (most likely). You then need to
+specify the path to the respective library's C header files. If they
+are located in e.g., @file{/sw/local/include}, do
+
+@example
+./configure CPPFLAGS=-I/sw/local/include
+@end example
+
+On my SUN Solaris workstation, I had to combine this into
+
+@example
+./configure CPPFLAGS='-I/sw/local/include -I/sw/tex/teTeX/1.0/include'\
+ LDFLAGS='-L/sw/local/lib -R/sw/local/lib -L/sw/tex/teTeX/1.0/lib/'
+@end example
+
+@noindent
+where the backslash denotes a continuation of the line.
+
+@node Build/install
+@section Build/install
+
+Once @file{configure} has been run, simply enter
+
+@example
+make
+@end example
+
+@noindent
+at the prompt to compile the C code, and build the documentation files.
+To install the files into the locations chosen earlier, type
+
+@example
+make install
+@end example
+
+@noindent
+You may need special privileges to install, e.g., if you are installing
+into system directories.
+
+@node Installation outside the texmf tree
+@section Installation outside the texmf tree
+
+In some cases, a dvipng binary installed outside the texmf tree will
+not be able to find virtual fonts, or the PostScript font maps
+(normally used by dvips). This may be because @emph{only}
+$SELFAUTOLOC, $SELFAUTODIR, and $SELFAUTOPARENT are used in the texmf
+tree configuration file @samp{texmf.cnf}. If so, give the switch
+@samp{--enable-selfauto-set} to @samp{./configure}. This will make
+dvipng adjust these three internally so that kpathsea thinks that
+dvipng @emph{is} installed in the texmf tree.
+
+@node Advice for non-privileged users
+@section Installation for non-privileged users
+
+Often people without system administration privileges want to install
+software for their private use. In that case you need to specify more
+options to the @file{configure} script, usually this is done by using
+the @samp{--prefix} option to the @file{configure} script, and let it
+point to the personal home directory. In that way, resulting binaries
+will be installed under the @file{bin} subdirectory of your home
+directory, manual pages under @file{man} and so on. That way, it is
+reasonably easy to maintain a bunch of additional packages, since the
+prefix argument is supported by most @file{configure} scripts.
+
+You'll have to add something like @file{/home/myself/bin} to your
+@code{PATH} shell variable, if it isn't there already, and similarly
+set the @code{INFOPATH} and @code{MANPATH} variables to be able to
+access the documentation.

+@c -----------------------
+
+This program makes PNG and/or GIF graphics from DVI files as obtained
+from @TeX{} and its relatives.
+
+If GIF support is enabled, GIF output is chosen by using the
+@samp{dvigif} binary or with the @samp{--gif} option.
+
+@ifclear man
+
+It is intended to produce anti-aliased screen-resolution images as fast
+as is possible. The target audience is people who need to generate and
+regenerate many images again and again. The primary target is the
+@previewlatex{} (X)Emacs package, a package to preview formulas from
+within (X)Emacs. Yes, you get to see your formulas in the (X)Emacs
+buffer, see @url{http://www.gnu.org/software/auctex/preview-latex.html}.
+
+Another example is WeBWorK, an internet-based method for delivering
+homework problems to students over the internet, giving students
+instant feedback as to whether or not their answers are correct, see
+@url{http://webwork.math.rochester.edu}.
+
+A more recent addition to the dvipng-using applications out there is
+MediaWiki, the software behind Wikipedia and many other wikis out
+there. Dvipng is used to render mathematical formulae from version
+1.8.0 of MediaWiki, see @url{http://www.mediawiki.org}.
+
+Other applications may also benefit, like web applications as latex2html
+and WYSIWYG editors like LyX.
+
+@ifset rawfile
+@section Benefits of dvipng
+@end ifset
+@end ifclear
+
+The benefits of @samp{dvipng}/@samp{dvigif} include
+
+@itemize @bullet
+@item
+Speed. It is a very fast bitmap-rendering code for DVI files, which
+makes it suitable for generating large amounts of images on-the-fly,
+as needed in @previewlatex{}, WeBWorK and others.
+
+@item
+It does not read the postamble, so it can be started before @TeX{}
+finishes. There is a @samp{--follow} switch that makes dvipng wait at
+end-of-file for further output, unless it finds the POST marker that
+indicates the end of the DVI.
+
+@item
+Interactive query of options. dvipng can read options interactively
+through stdin, and all options are usable. It is even possible to change
+the input file through this interface.
+
+@item
+Supports PK, VF, PostScript Type1, and TrueType fonts, subfonts (i.e.,
+as used in CJK-@LaTeX{}), color specials, and inclusion of PostScript,
+PNG, JPEG or GIF images.
+
+@item
+and more...
+
+@end itemize
+
+@ifset rawfile
+@section Installation
+
+Read @file{INSTALL}, included in the distribution.
+
+@section Usage
+
+To use dvipng at its simplest, simply type
+
+@example
+dvipng foo
+@end example
+
+@noindent
+where @file{foo.dvi} is the output of @TeX{} that you want to convert to
+PNG format. If there are four pages in @file{foo.dvi}, those pages will
+be output as @file{foo1.png}, @file{foo2.png}, @file{foo3.png}, and
+@file{foo4.png}, respectively.
+
+Many options are available (see the info manual). For a brief summary
+of available options, just type
+
+@example
+dvipng --help
+@end example
+
+@section Availability
+
+The dvipng package is available at Savannah, the GNU project site. Since
+dvipng is not part of the GNU project, although released under the GNU
+GPL, the web address is
+@url{http://savannah.nongnu.org/projects/dvipng}. Instructions for
+anonymous CVS access can be found at
+@url{http://savannah.nongnu.org/cvs/?group=dvipng}.
+
+@section Contacts
+
+Bug reports should be sent to @email{dvipng@@nongnu.org}.
+
+Questions, suggestions for new features, pleas for help, and/or praise
+should go to @email{dvipng@@nongnu.org}. For more information on this
+mailing list, send a message with just the word `help' as subject or
+body to @email{dvipng-request@@nongnu.org} or look at
+@url{http://lists.nongnu.org/mailman/listinfo/dvipng}.
+
+Offers to support further development will be appreciated. For developer
+access, ask on @email{dvipng@@nongnu.org}.

+@section Todo
+

+@item
+Use gs interpreter library for speed and possibly for functionality.
+
+@item
+Add more color models for xcolor compatibility
+
+@item
+Enable a named pipe as DVI
+
+@item
+Further speed improvements.
+
+@item
+Other output specials and source specials.
+
+@item
+Clean internal structures. Overhaul file handling.
