First of let me admit that I've very new to the LaTeX, so this may be obvious and I just do see it, but here's my question:
I'm trying to write a set of macros to automatically downsample images... sort of like
degrade.sty, but for images that are inserted at arbitrary sizes in the document. What I would like to do is redefine
\includegraphics so that this can be accomplished for existing documents. In order to find the intended graphics file, I need to know what paths are currently in the graphics path. Alas, I cannot figure out how to determine what those paths are. Is this possible?
