211
212CV uses Pixbuf to load images. Pixbuf is not considered safe for this
213purpose, though (from the gtk-2.2 release notes):
214
215"While efforts have been made to make gdk-pixbuf robust against invalid
216images, using gdk-pixbuf to load untrusted data is not recommended, due to
217the likelyhood that there are additional problems where an invalid image
218could cause gdk-pixbuf to crash or worse."
120 219
121=head1 BUGS/TODO 220=head1 BUGS/TODO
221
222 Pixbuf doesn't honor G_BROKEN_FILENAMES, so accessing files with names
223 incompatible with utf-8 fails.
