NAME

  bmpp - Bitmap to PS/PDF converter

SYNOPSIS

  bmpp [-l<driver>[.<mode>][,<key>[=<value>]...]] [<options>] <file(s)>

DESCRIPTION

The program converts bitmap images from PNG, JPEG, or TIFF to PS/EPS and PDF.

Drivers:
- ps
  PostScript file, can be used to print.
- eps
  Encapsulated PostScript (EPS), image for inclusion into documents.
- pdf
  Portable document format (PDF).
- bb
  Bounding box information only, no image.

Output modes:
- object
  Object which can embedded into a text or drawing by a text processing
  or drawing software.
- image
  Image for stand-alone viewing.
- document
  Fit the output to a given paper size for printing.

OPTIONS

-h
--help
	Show help text.

-v
--version
	Show version number.

-L
--license-terms
	Shows license terms.

-t <type>
	Input image type, "png", "jpeg", or "tiff", must be specified when
	processing standard input or if the input file name suffix does
	not indicate the type.

-m
	Make mode: Avoid unnecessary conversions if output file is up to date.
	Only used when processing a directory.

-s
	Write to standard output, not to a file.

-o <key>[=<value>]
	Detailed conversion options.

NAME=VALUE PAIRS

The key=value pairs set detailed conversion options. For boolean
settings the value can be omitted, the presence of the name sets the option
to active.
The following keys (and values) can be used:

level=<pslevel>
	PS level, "2" or "3".  Default: 3.

color[=<boolean>]
	Color output for PS/EPS output. For PDF output color is
	always enabled. This setting is ignored when passing DCT data from
	JPEG files to output directly.
	Default: On.

dsc[=<boolean>]
	DSC comments when producing PS/EPS output.
	Default: Off, except for ps.document.

draft[=<boolean>]
	Draft mode (small placeholder image only). Default: Off.

predictor=<predictor>
	Predictor for flate compressions, "tiff", "sub", "up",
	"average", or "paeth". Default: none.

duplex[=<boolean>]
	Duplex mode when producing documents. Default: Off.

tumble[=<boolean>]
	Tumble in addition to duplex mode. Default: Off.

dct[=<boolean>]
	Direct pass-through of DCT encoded data found in JPEG
	files. Default: On.

bg=<int>:<int>:<int>[:<boolean>]
	Default background RGB color to be used if the input file
	does not contain a background color chunk. The optional boolean value
	at the end can be used to enforce this background over the background
	chunk. RGB values are in the range 0...255.
	Default: White, off.

interpolation[=<boolean>]
	Image interpolation. Default: On.

jpeg-interpolation[=<boolean>]
	Image interpolation if DCT data is passed through directly.
	Default: Off.

resolution=<resolution>
	Resolution, either "1:1" (use a 1 point x 1 point square for
	each source pixel), "chunk" (use resolution data from image) or an
	integer value for dpi.
	Default: 1:1 for objects, chunk for images,
	fit to paper size for documents.

paper=<paper>
	Paper size for documents. The paper size must be configured
	in a dk3paper.conf file. Only one from "resolution" or "paper" can be
	used.

make[=<boolean>]
	Make mode when processing directories.
	Default: Off.

bpc[=<boolean>]
	Reduce the number of bits per component. Default: On.

EXIT STATUS

0 on success, all other exit status codes indicate an error.

PREFERENCES

/print/ps/level
	Default PS level, 2 or 3.

EXAMPLES

bmpp -lps.document,level=2,paper=A4,duplex,bpc myfax.tif
	converts a fax TIFF file "myfax.tif" to "myfax.ps" for a PS 2 printer.

bmpp -l pdf.document,paper=A4,duplex fax.tif
	creates a PDF file fax.pdf.

bmpp -l ps.object screenshot.png
	creates a PS object file screenshot.ps for use with latex/dvips.

bmpp -l pdf.object screenshot.png
	creates a PDF object file screenshot.pdf for use with pdflatex.

bmpp -l ps.image file.png
	creates a PS image file.ps.

bmpp -l pdf.image file.png
	creates a PDF image file.pdf.

FILES

dk3paper.conf
	If paper=... the named paper size must be configured in a
	dk3paper.conf file.

RESTRICTIONS

The program uses the TIFFReadRGBAImage() function from the libtiff library to
read TIFF images. The input file must meet the following conditions:
- The file must be compliant to the "TIFF baseline v6.0 standard".
- The number of bits of component must be 8 or less.
- The frames must not be too large, the system must be able to allocate the
  4*w*h bytes needed for image date in one piece.

TIFF refers to a group of different compression and encoding mechanisms.
A TIFF file is a sequence of data chunks, each data chunk contains a tag
(chunk type identifier). A lot of tags is defined in standards, i.e. the
"TIFF baseline v6.0 standard". Some software vendors add vendor-specific
or non-standard tags when writing TIFF files.
So when processing TIFF files in bmpp, you should not be surprised to see
warnings or error messages about unknown TIFF tags.
Neither bmpp nor the tifflib library are to blame for this, it's the
responsibility of the people adding the non-standard tags.
Sometimes bmpp can read the image despite of the warnings/errors.

If you create bitmaps you want to process with bmpp, you should create PNG
images instead of TIFF images if you have the choice.

ansi2knr.c is included in this distribution by permission of L. Peter Deutsch,
sole proprietor of its copyright holder, Aladdin Enterprises of Menlo Park, CA.
ansi2knr.c is NOT covered by the above copyright and conditions, but instead
by the usual distribution terms of the Free Software Foundation; principally,
that you must include source code if you redistribute it.  (See the file
ansi2knr.c for full details.)  However, since ansi2knr.c is not needed as part
of any program generated from the IJG code, this does not limit you more than
the foregoing paragraphs do.

The Unix configuration script "configure" was produced with GNU Autoconf.
It is copyright by the Free Software Foundation but is freely distributable.
The same holds for its supporting scripts (config.guess, config.sub,
ltconfig, ltmain.sh).  Another support script, install-sh, is copyright
by M.I.T. but is also freely distributable.

It appears that the arithmetic coding option of the JPEG spec is covered by
patents owned by IBM, AT&T, and Mitsubishi.  Hence arithmetic coding cannot
legally be used without obtaining one or more licenses.  For this reason,
support for arithmetic coding has been removed from the free JPEG software.
(Since arithmetic coding provides only a marginal gain over the unpatented
Huffman mode, it is unlikely that very many implementations will support it.)
So far as we are aware, there are no patent restrictions on the remaining
code.

The IJG distribution formerly included code to read and write GIF files.
To avoid entanglement with the Unisys LZW patent, GIF reading support has
been removed altogether, and the GIF writer has been simplified to produce
"uncompressed GIFs".  This technique does not use the LZW algorithm; the
resulting GIF files are larger than usual, but are readable by all standard
GIF decoders.

We are required to state that
    "The Graphics Interchange Format(c) is the Copyright property of
    CompuServe Incorporated.  GIF(sm) is a Service Mark property of
    CompuServe Incorporated."
