graphicscache – Cache includegraphics calls

This LaTeX package provides caching of \includegraphics calls, with several useful effects:

• Recompilations are much faster (10x speedup observed).
• Images can be postprocessed with ghostscript before inclusion, thus:
  • Automatic downscaling to specified DPI
  • Automatic JPEG compression with configurable quality
  • Much smaller files (e.g. 10MB instead of 150MB)!

Note: Due to the one-by-one invocation of pdflatex and ghostscript for each graphics element, the first compilation is typically slower than usual.

Note: graphicscache needs the \write18 call (also called shell escape). This is a security risk if you have untrusted TeX sources.

graphicscache supports pdfLaTeX and LuaLaTeX; XeLaTeX is not supported.
