Yeah, I think this is one of those image formats we'll just have to defer users to ImageMagick if they want to see... This reminds me: Since we don't really want to point users towards compiling with ImageMagick due to security concerns -- would it make sense to write a shim over external utilities to handle exotic formats? I mean, it would just have to call "convert" in a temp buffer to some format we do handle (like PNG). But I guess that doesn't really deal with the security issue, as buffer overflows in "convert" will do pretty much the same as in Emacs. But it would lead to fewer segfaults in Emacs itself, so perhaps it's worth doing? It'd be a pretty trivial shim, and we could deprecate compiling with ImageMagick for sure. -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
