212
213CV uses Pixbuf to load images. Pixbuf is not considered safe for this
214purpose, though (from the gtk-2.2 release notes):
215
216"While efforts have been made to make gdk-pixbuf robust against invalid
217images, using gdk-pixbuf to load untrusted data is not recommended, due to
218the likelyhood that there are additional problems where an invalid image
219could cause gdk-pixbuf to crash or worse."
123 220
124=head1 BUGS/TODO 221=head1 BUGS/TODO
222
223 Pixbuf doesn't honor G_BROKEN_FILENAMES, so accessing files with names
224 incompatible with utf-8 fails.
