TeX needs for the postscript output all figures in Postscript (.ps) or Encapsulated Postscript (.eps) format. pdfLatex is different to TeX and needs pdf-format and can convert also jpeg. For more information to pdflatex look at the TeX-FAQ at CTAN.
ps- and eps-figures are a good format for all vector graphics but become enormous file-sizes when using bimapped figures. If your printer understand Postscript Level 2 you can convert these files with
 `convert myFile.??? eps2:myFile.eps`
For more Information to Postscript Level 2 have a look at imgtops2.

Another way is to compress these eps-figures of Postscript Level 1 and decompress them by LaTeX on the run. The only problem is, that LaTeX needs the size of the figure, before unzipping the file. Therefore we need a second file, which has only one line, the size of the Bounding Box:

 `%%BoundingBox: 0 0 684 676`
This is one of the first line in every eps-file. With the following Shell-script every figure can be converted to eps-format with an additional-file (.eps.bb) for the bounding box:

 ```#!/bin/bash # voss /010506 # convert any file to eps and make a minifile with # info of the bounding box # usage: makeEPS file.??? # program convert is part of ImageMagic # dat=\$1 OUT=\${dat%%.*} # without suffix echo "InputFile =\$1" echo "OutputFile =\$OUT.eps.gz" echo "BoundingBoxFile=\$OUT.eps.bb" convert \$1 \$OUT.eps grep BoundingBox \$OUT.eps > \$OUT.eps.bb ls -l \$OUT.eps gzip \$OUT.eps ls -l \$OUT*```
Save it in any dir and make it executable. The program convert is part of the ImageMagick package and available in the net. For example:
 ```voss@maria:~/LaTeX> makeEPS myFigure.pcx InputFile =myFigure.pcx OutputFile =myFigure.eps.gz BoundingBoxFile=myFigure.eps.bb -rw-r--r-- 1 voss users 495620 Mai 25 13:26 myFigure.eps -rw-r--r-- 1 voss users 62 Mai 25 13:25 myFigure.eps.bb -rw-r--r-- 1 voss users 39346 Mai 25 13:25 myFigure.eps.gz -r-xr-xr-x 1 voss users 92459 Jun 23 1994 myFigure.pcx``` The compression factor for this example is about 1:10, a good result. The contents of the .bb-file is ```%%BoundingBox: 0 0 1304 1472 %%PageBoundingBox: 0 0 1305 1473 ```
TeX needs some information about the file-suffixes and an unzipped tool for the decompressing. The package graphics looks for a file graphic.cfg like the following one, which is in /usr/share/texmf/tex/latex/config, but maybe in any other valid tex-dir:
 ```\@ifundefined{pdfoutput}% {\let\pdfoutput\@undefined \ExecuteOptions{dvips}% \AtEndOfPackage{% \@ifundefined{DeclareGraphicsRule}% {\let\DeclareGraphicsRule\@undefined}% {\DeclareGraphicsRule{.pz}{eps}{.bb}{}% \DeclareGraphicsRule{.eps.Z}{eps}{.eps.bb}{}% \DeclareGraphicsRule{.ps.Z}{eps}{.ps.bb}{}% \DeclareGraphicsRule{.ps.gz}{eps}{.ps.bb}{}% \DeclareGraphicsRule{.eps.gz}{eps}{.eps.bb}{}}}% }% {\ifcase\pdfoutput \let\pdfoutput\@undefined \ExecuteOptions{dvips}% \AtEndOfPackage{% \@ifundefined{DeclareGraphicsRule}% {\let\DeclareGraphicsRule\@undefined}% {\DeclareGraphicsRule{.pz}{eps}{.bb}{}% \DeclareGraphicsRule{.eps.Z}{eps}{.eps.bb}{}% \DeclareGraphicsRule{.ps.Z}{eps}{.ps.bb}{}% \DeclareGraphicsRule{.ps.gz}{eps}{.ps.bb}{}% \DeclareGraphicsRule{.eps.gz}{eps}{.eps.bb}{}}}% \else \ExecuteOptions{pdftex} \fi}%```
You can modify this file as you like. If you don't have this file, save it in a texdir and run texhash. With this config-file you are able to insert in LaTeX the zipped files.
