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

metapixel - generator for photomosaics SYNOPSIS
metapixel-prepare [options] [srcdir] [destdir] prepares the pictures in srcdir by creating resized images and a table file in destdir metapixel [options] [--metapixel input.jpg output.png --library destdir] creates a photomosaic output.png using input.jpg as the input image and destdir/tables.mxt as table file DESCRIPTION
This manual page documents briefly the metapixel and metapixel-prepare commands. For more information check the README file included in the distribution. metapixel is a program for generating photomosaics. It can generate classical photomosaics, in which the source image is viewed as a matrix of equally sized rectangles for each of which a matching image is substitued, as well as collage-style photomosaics, in which rectangular parts of the source image at arbitrary positions (i.e. not aligned to a matrix) are substituted by matching images. metapixel-prepare is a utility that needs to be run before metapixel can be used. It prepares your source images so that they can be used by metapixel to create the actual photomosaic. USAGE
metapixel-prepare srcdir destdir has to be run first. srcdir is the path to the directory containing the source images, e.g. ~/Pic- tures/Holidays. destdir, e.g. ~/.metapixel, is the path to the directory where you want to store the rescaled images and the tables.mxt in- dex file. This directory should be created manually before running metapixel-prepare. metapixel --metapixel input.jpg output.png --library destdir is then used to transform an image (input.jpg) into a mosaic (output.png) us- ing the source images (described by destdir/tables.mxt). OPTIONS
The options are described in the README file or by running metapixel or metapixel-prepare with the --help option. SEE ALSO
The README file is included in the Metapixel distribution. AUTHOR
