|
|
226 | =head1 ENVIRONMENT |
|
|
227 | |
|
|
228 | =over 4 |
|
|
229 | |
|
|
230 | =item CV_EDITOR |
|
|
231 | |
|
|
232 | The program that gets executed when the user presses C<CTRL-e> in the |
|
|
233 | Schnauzer or image window. The default is C<gimp>. |
|
|
234 | |
|
|
235 | =item CV_PRINT_DESTINATION |
|
|
236 | |
|
|
237 | The default (perl-style) destination to use in the print dialog. |
|
|
238 | |
|
|
239 | =item CV_TRASHCAN |
|
|
240 | |
|
|
241 | When set, must point to a directory where all files that are deleted are |
|
|
242 | moved to. If unset, files that are deleted are really being deleted. |

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