image - Translate LaTeX documents to GIF images. SYNOPSIS
imagen <base> DESCRIPTION
This manual page documents briefly the imagen command. This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page. imagen is a simple shell script that translates a LaTeX document into many images. Please consult the hevea manual for explanation how to use imagen in conjunction with hevea. The Debian version of HeVeA differs from the original HeVeA distribution in that pictures are by default generated in the png format instead of gif. To regain the original behavior you have to modify your LaTeX input (see hevea (1)) and invoke imagen with the -gif option. OPTIONS
A summary of options are included below. -png Produce images in the png format. On a Debian system this is the default. -gif Produce images in gif format instead of png. -pnm Produce images in pnm format. -mag nnnn, Change the enlarging ratio that is applied while translating DVI into Postscript. More precisely, dvips is run with -xnnnn option. Default value for this ration is 1414, this means that, by default, imagen magnifies LaTeX output by a factor of 1.414. -t arg Pass option -t arg to dvips. For instance, using -t a3 may help when images are truncated on the right. -pdf Have imagen call pdflatex instead of latex -extra command, Insert command as an additional stage in imagen ppm to png/gif production chain. command is a Unix filter that expects a ppm image in its standard input and outputs a ppm image on its standard output. A sensible choice for command is one command from the netpbm package or several such commands piped together. -quant number Add an extra color quantization step in imagen ppm image production chain, where number is the maximal number of colors in the pro- duced images. This option may be needed in response of a failure in the image production chain. It can also help in limiting image files size. SEE ALSO
hevea(1), latex(1), gs(1), dvips(1), ppmtopng(1), ppmtogif(1) The HeVeA documentation can be found on the HeVeA home page On a Debian system it can also be accessed at /usr/share/doc/hevea-doc/html, provided the package hevea-doc (from the non-free section) is installed. AUTHOR
Imagen is part of HeVeA, written by Luc Maranget <>. This manual page was compiled by Ralf Treinen <> from the HeVeA documentation for the Debian GNU/Linux system (but may be used by others). IMAGEN(1)

img-png - Img, Portable Network Graphics format (png) SYNOPSIS
package require Tk package require img::png ?1.4? image create photo ?name? ?options? _________________________________________________________________ DESCRIPTION
The package img::png is a sub-package of Img. It can be loaded as a part of the complete Img support, via package require Img, or on its own, via package require img::png. Like all packages of Img it does not provide new commands, but extends the existing Tk command image so that it supports files containing raster images in the Portable Network Graphics format (png). More specifically img::png extends Tk's photo image type. The name of the new format handler is png. This handler provides new additional configuration options. See section PNG OPTIONS for more detailed explanations. All of the above means that in a call like image create photo ?name? ?options? [1] Image data in png format (options -data and -file) is detected automatically. [2] The format name png is recognized by the option -format. In addition the value for the option is treated as list and may contain any of the special options listed in section PNG OPTIONS. PNG OPTIONS
The handler provides no true options at all, but accepts pairs of keys and values when writing a PNG file. Each pair will be written as a named text chunk where the key provides the name of the chunk and the value its contents. For example png Author <name> Title <title> Description ... TRANSPARENCY
If you want to write images to disk which contain transparency information (e.g. PNG with alpha channel) you need at least Tk 8.3. SEE ALSO
