=head1 SECURITY CONSIDERATIONS |
245 |
|
246 |
CV uses Pixbuf to load images. Pixbuf is not considered safe for this |
247 |
purpose, though (from the gtk-2.2 release notes): |
248 |
|
249 |
"While efforts have been made to make gdk-pixbuf robust against invalid |
250 |
images, using gdk-pixbuf to load untrusted data is not recommended, due to |
251 |
the likelyhood that there are additional problems where an invalid image |
252 |
could cause gdk-pixbuf to crash or worse." |
253 |
|
254 |
=head1 BUGS/TODO |
255 |
|
256 |
Pixbuf doesn't honor G_BROKEN_FILENAMES, so accessing files with names |
257 |
incompatible with utf-8 fails. |
258 |
|
259 |
rotate on disk |
260 |
print |
261 |
lots of ui issues |
262 |
save(?) |
263 |

264 |
