Problems by compressing pm3d generated pic.

[Martin Horvat]

I have some problems by using the compression tool on with pm3d generated maps:
awk -f pm3dConvertToImage.awk <thefile.ps >smallerfile.ps

It works fine on for example 2 maps on a multiplot, but it breaks down for my 9 maps. The other tool:
awk -f pm3dCompress.awk thefile.ps >smallerfile.ps

doesn't wont to work on any graphs that I made by now. Can somebody suggest what should I do, but not changing the number of pictures.

The GNU Awk 3.1.0 finishes the work with no problem. But when I open the pic. with gv the gs reports (by using pm3dCompress writes out):

This compession utility is really a big plus for gnuplot in comparison to other plot programs.

Thanks for any help.

I found out that "pm3dImage" in eps has some lines to long for gs (max. length 255). Then when I repair that lines I get to many lines in stack of "pm3dImage". If somebody has an automatic solution I would appreciate. Now I edit this eps/ps files by hand and it isn't much fun.

I need this solution as fast as possible.
