This package contains a pair of command-line utilites for translating between bitmap images (JPEG, PNG, GIF, Targa, BMP, etc.) and PostScript files. It requires Python (version 2.2 or higher) and the Python Imaging Library.
% ls -l test.gif -rw------- 2 dougz dougz 24893 Jan 30 19:25 test.gif % imgtops test.gif > output.eps processing [test.gif]... % ls -l output.eps -rw------- 1 dougz dougz 44122 Feb 22 20:37 output.eps
Here's the same task, using the pnmtops utility of Netpbm:
% giftopnm test.gif | pnmtops -noturn > output-pnmtops.eps pnmtops: writing color PostScript... % ls -l output-pnmtops.eps -rw------- 1 dougz dougz 444608 Feb 22 20:38 output-pnmtops.eps %Note that imgtops's output file is 1/10 the size of netpbm's. The savings aren't always this dramatic, but they're usually significant.
imgtops also features a batch mode for converting multiple images at once:
% ls bw.jpg cmyk.tif color.jpg color2.jpg flower.jpg gif.gif gif2.gif png24.png png8.png % imgtops -b * processing [bw.jpg]... processing [cmyk.tif]... processing [color.jpg]... processing [color2.jpg]... processing [flower.jpg]... processing [gif.gif]... processing [gif2.gif]... processing [png24.png]... processing [png8.png]... % ls *.ps bw.ps cmyk.ps color.ps color2.ps flower.ps gif.ps gif2.ps png24.ps png8.psimgtops can optionally use PostScript Level 3 features to reduce the output size even more:
% imgtops cmyk.tif > level2.ps processing [cmyk.tif]... % imgtops -3 cmyk.tif > level3.ps processing [cmyk.tif]... % ll lev*ps -rw------- 1 dougz dougz 172888 Feb 22 20:52 level2.ps -rw------- 1 dougz dougz 61702 Feb 22 20:52 level3.ps
