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.

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 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).

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.

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).

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.

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... - - -File: dvipng.info, Node: Installation, Next: Basic usage, Prev: Introduction, Up: Top - -2 Installation -************** - -Installing dvipng should be simple: merely './configure', 'make', and -'make install'. - -* Menu: - -* Prerequisites:: -* Configure:: -* Build/install:: -* Installation outside the texmf tree:: -* Advice for non-privileged users:: - - -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).

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. - - -File: dvipng.info, Node: Graphics, Next: Color, Prev: Command-line options, Up: Top - -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. - - -File: dvipng.info, Node: Color, Next: Diagnosing problems, Prev: Graphics, Up: Top - -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. - - -File: dvipng.info, Node: Diagnosing problems, Next: Credits, Prev: Color, Up: Top - -7 Diagnosing problems -********************* - -You've gone through all the trouble of installing dvipng, carefully read -all the instructions in this manual, and still can't get something to -work.

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.

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.

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.

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.

You can -also specify 'Transparent' or 'transparent' which will give you a -transparent background with the normal background as a fallback color.

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.

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.

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. - -@node Diagnosing problems -@chapter Diagnosing problems - -@cindex problems -@cindex trouble -@cindex debugging - -You've gone through all the trouble of installing dvipng, carefully read -all the instructions in this manual, and still can't get something to -work.
