ENVIRONMENT |
| 71 |
CV_EDITOR |
| 72 |
The program that gets executed when the user presses "CTRL-e" in the |
| 73 |
Schnauzer or image window. The default is "gimp". |
| 74 |
|
| 75 |
CV_PRINT_DESTINATION |
| 76 |
The default (perl-style) destination to use in the print dialog. |
| 77 |
|
| 78 |
CV_TRASHCAN |
| 79 |
When set, must point to a directory where all files that are deleted |
| 80 |
are moved to. If unset, files that are deleted are really being |
| 81 |
deleted. |
| 82 |
|
| 83 |
SECURITY CONSIDERATIONS |
| 84 |
CV uses Pixbuf to load images. Pixbuf is not considered safe for this |
| 85 |
purpose, though (from the gtk-2.2 release notes): |
| 86 |
|
| 87 |
"While efforts have been made to make gdk-pixbuf robust against invalid |
| 88 |
images, using gdk-pixbuf to load untrusted data is not recommended, due |
| 89 |
to the likelyhood that there are additional problems where an invalid |
| 90 |
image could cause gdk-pixbuf to crash or worse." |
| 91 |
|
| 92 |
BUGS/TODO |
| 93 |
Pixbuf doesn't honor G_BROKEN_FILENAMES, so accessing files with names |
| 94 |
incompatible with utf-8 fails. |
| 95 |
|
| 96 |
rotate on disk |
| 97 |
print |
| 98 |
lots of ui issues |
| 99 |
