143 | s set scaling mode to 'bilinear' (default) |
|
|
144 | S set scaling mode to 'hyper' (slowest) |
|

|
|
148 | |
|
|
149 | The following keys are redirected to the default visual schnauzer window: |
|
|
150 | |
|
|
151 | space next image |
|
|
152 | backspace last image |
|
|
153 | |

|
|

|
|
159 | backspace move to and display previous image |
|

162 | cursor keys move selection |
|
|
163 | page-up move one page up |
|
|
164 | page-down move one page down |
|
|
165 | home move to first file |
|
|
166 | end move to last file |
|
|
167 | |
|
|
168 | ctrl-g generate icons for the selected files |
|
|
169 | ctrl-d delete selected files WITHOUT ASKING AGAIN |
|
|
170 | |
|
|
171 | =head1 SECURITY CONSIDERATIONS |
|
|
172 | |
|
|
173 | CV uses Pixbuf to load images. Pixbuf is not considered safe for this |
|
|
174 | purpose, though (from the gtk-2.2 release notes): |
|
|
175 | |
|
|
176 | "While efforts have been made to make gdk-pixbuf robust against invalid |
|
|
177 | images, using gdk-pixbuf to load untrusted data is not recommended, due to |
|
|
178 | the likelyhood that there are additional problems where an invalid image |
|
|
179 | could cause gdk-pixbuf to crash or worse." |
|
|
180 | |
|
|
181 | =head1 BUGS/TODO |
|
|
182 | |
|
|
183 | Pixbuf doesn't honor G_BROKEN_FILENAMES, so accessing files with names |
|
|
184 | incompatible with utf-8 fails. |
|
|
185 | |
|
|
186 | rotate on disk |
|
|
187 | print |
|
|
188 | lots of ui issues |
|
|
189 | save(?) |
|
|
190 | preferences |
|
|
191 | ctrl-u in schnauzer |
