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:

# 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
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
-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:
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.
