176 | =head1 NAME |
|
|
177 | |
|
|
178 | cv - a fast gtk+ image viewer loosely modeled after XV |
|
|
179 | |
|
|
180 | =head1 SYNOPSIS |
|
|
181 | |
|
|
182 | cv [file...] |
|
|
183 | |
|
|
184 | =head1 FEATURES |
|
|
185 | |
|
|
186 | CV is supposed to work similar to the venerable XV image viewer, just |
|
|
187 | faster. Why faster? |
|
|
188 | |
|
|
189 | =over 4 |
|
|
190 | |
|
|
191 | =item * optimized directory scanning algorithm |
|
|
192 | |
|
|
193 | The directory scanning in CV uses some tricks that - on most modern |
|
|
194 | filesystems - makes it possible to detect filetypes faster than stat()'ing |
|
|
195 | every file. This makes CV suitable for directories with lots of files |
|
|
196 | (10000+). |
|
|
197 | |
|
|
198 | This algorithm is quite unprecise - it doesn't make a difference between |
|
|
199 | files, device nodes, symlinks and the like, and filetype detection is done |
|
|
200 | using the file extension only. |
|
|
201 | |
|
|
202 | On the positive side, it is usually many orders of magnitude faster than |
|
|
203 | traditional scanning techniques (good for directories with 10000 or |
|
|
204 | 100000+ files). |
|
|
205 | |
|
|
206 | =item * queuing for all time-consuming background tasks |
|
|
207 | |
|
|
208 | All tasks, such as unlinking files or generating thumbnails, that can be |
|
|
209 | done in the background will be done so - no waiting required, even when |
|
|
210 | changing directories. |
|
|
211 | |
|
|
212 | =item * use of asynchronous I/O |
|
|
213 | |
|
|
214 | CV tries to use asynchronous I/O whereever it makes sense, for example |
|
|
215 | while scanning directories, waiting for stat data, unlinking files or |
|
|
216 | generating thumbnails. This usually decreases scanning times for large |
|
|
217 | directories a bit (especially on RAID devices and over NFS) and makes CV |
|
|
218 | much more interactive. |
|
|
219 | |
|
|
220 | =item * fast image loading |
|
|
221 | |
|
|
222 | The time span between the user issuing a command and displaying the new |
|
|
223 | image should be as small as possible. CV uses optimized (especially |
|
|
224 | for JPEG) loading functions and sacrifices some quality (e.g no gamma |
|
|
225 | correction, although this might change) to achieve this speed. |
|
|
226 | |
|
|
227 | =item * fast thumbnail creation |
|
|
228 | |
|
|
229 | Thumbnail creation uses both CPU and Disk-I/O. CV interleaves both, so |
|
|
230 | on modern CPUs, thumbnailing is usually limited by I/O speed. Thumbnail |
|
|
231 | creation for JPEGs has been specially optimized and can even take |
|
|
232 | advantage of multiple CPUs. |
|
|
233 | |
|
|
234 | =item * minimum optical clutter |
|
|
235 | |
|
|
236 | CV has no menus or other user interface elements that take up a lot of |
|
|
237 | screen space (or are useful for beginning users). The schnauzer windows |
|
|
238 | can also be somewhat crowded. |
|
|
239 | |
|
|
240 | The point of an image viewer is viewing images, not a nice GUI. This is |
|
|
241 | similar to XV's behaviour. |
|
|
242 | |
|
|
243 | =item * efficient (and hard to learn) user interface |
|
|
244 | |
|
|
245 | CV uses key combinations. A lot. If you are an experienced XV user, you |
|
|
246 | will find most of these keys familiar. If not, CV might be hard to use at |
|
|
247 | first, but will be an efficient tool later. |
|
|
248 | |
|
|
249 | =item * multi-window GUI |
|
|
250 | |
|
|
251 | CV doesn't force you to use a specific layout, instead it relies on your |
|
|
252 | window manager, thus enabling you to chose whatever layout that suits you |
|
|
253 | most. |
|
|
254 | |
|
|
255 | =item * i18n'ed filename handling throughout |
|
|
256 | |
|
|
257 | As long as glib can recognize your filename encoding (either UTF-8 or |
|
|
258 | locale-specific, depending on the setting of G_BROKEN_FILENAMES) and you |
|
|
259 | have the relevant fonts, CV will display your filenames correctly. |
|
|
260 | |
|
|
261 | =item * extensible through plug-ins |
|
|
262 | |
|
|
263 | I have weird plug-ins that access remote databases to find a |
|
|
264 | directory. This is not likely to be of any use to other people. Likewise, |
|
|
265 | others might have weird requirements I cannot dream of. |
|
|
266 | |
|
|
267 | =item * filename clustering |
|
|
268 | |
|
|
269 | Among the standard plug-ins is a filename clustering plug-in, that (in |
|
|
270 | case of tens of thousands images in one directory) might be able to |
|
|
271 | cluster similar names together. |

276 | |
|
|
277 | =head2 THE IMAGE WINDOW |
|
|
278 | |
|
|
279 | You can use the following keys in the image window: |
|
|
280 | |
|
|
281 | q quit the program |
|
|
282 | < half the image size |
|
|
283 | > double the image size |
|
|
284 | , shrink the image by 10% |
|
|
285 | . enlarge the image by 10% |
|
|
286 | n reset to normal size |
|
|
287 | m maximize to screensize |
|
|
288 | M maximize to screensize, respecting image aspect |
|
|
289 | ctrl-m toggle maxpect-always mode |
|
|
290 | ctrl-sift-m toggle using current image size as max image size |
|
|
291 | u uncrop |

|
|
346 | |
|
|
347 | ^ go to parent directory (caret). |
|
|
348 | |
|
|
349 | 0-9, |
|
|
350 | a-z find the first filename beginning with this letter |
|
|
351 | |
|
|
352 | Right-clicking into the schnauzer window displays a pop-up menu with |
|
|
353 | additional actions. |
|
|
354 | |
|
|
355 | =head3 SELECTION |
|
|
356 | |
|
|
357 | You can select entries in the Schnauzer in a variety of ways: |
|
|
358 | |
|
|
359 | =over 4 |
|
|
360 | |
|
|
361 | =item Keyboard |
|
|
362 | |
|
|
363 | Moving the cursor with the keyboard will first deselect all files and then |
|
|
364 | select the file you moved to. |
|
|
365 | |
|
|
366 | =item Clicking |
|
|
367 | |
|
|
368 | Clicking on an entry will select the one you clicked and deselect all |
|
|
369 | others. |
|
|
370 | |
|
|
371 | =item Shift-Clicking |
|
|
372 | |
|
|
373 | Shift-clicking will toggle the selection on the entry under the mouse. |
|
|
374 | |
|
|
375 | =item Dragging |
|
|
376 | |
|
|
377 | Dragging will select all entries between the one selected when pushing the |
|
|
378 | button and the one selected when releasing the button. If you move above |
|
|
379 | or below the schnauzer area while drag-selecting, the schnauzer will move |
|
|
380 | up/down one row twice per second. In addition, horizontal mouse movement |
|
|
381 | acts as a kind of invisible horizontal scrollbar. |
|
|
382 | |
|
|
383 | =item Hint: double-click works while click-selecting |
|
|
384 | |
|
|
385 | You can double-click any image while click-selecting to display it |
|
|
386 | without stopping the selection process. This will act as if you normally |
|
|
387 | double-clicked the image to display it, and will toggle the selection |
|
|
388 | twice, resulting in no change. |

392 | =head1 FILES |
|
|
393 | |
|
|
394 | When starting, CV runs the F<.cvrc> file in your F<$HOME> directory as if |
|
|
395 | it were a perl script. in that, you will mostly load plug-ins. |
|
|
396 | |
|
|
397 | Example: |
|
|
398 | |
|
|
399 | system "fping -q -t 10 ether" |
|
|
400 | or require "/fs/cv/cvplugin.pl"; |
|
|
401 | |
|
|
402 | This will load a plug-in, but only if the machine I<ether> is reachable |
|
|
403 | (supposedly the plug-in is networked in some way :). |
|

407 | =over 4 |
|
|
408 | |
|
|
409 | =item CV_EDITOR |
|
|
410 | |
|
|
411 | The program that gets executed when the user presses C<CTRL-e> in the |
|
|
412 | Schnauzer or image window. The default is C<gimp>. |
|
|
413 | |
|
|
414 | =item CV_PRINT_DESTINATION |
|
|
415 | |
|
|
416 | The default (perl-style) destination to use in the print dialog. |
|
|
417 | |
|
|
418 | =item CV_TRASHCAN |
|
|
419 | |
|
|
420 | When set, must point to a directory where all files that are deleted are |
|
|
421 | moved to. If unset, files that are deleted are really being deleted. |

425 | =head1 SECURITY CONSIDERATIONS |
|
|
426 | |
|
|
427 | CV uses Pixbuf to load non-JPEG images. Pixbuf is not considered safe for |
|
|
428 | this purpose, though (from the gtk-2.2 release notes): |
|
|
429 | |
|
|
430 | "While efforts have been made to make gdk-pixbuf robust against invalid |
|
|
431 | images, using gdk-pixbuf to load untrusted data is not recommended, due to |
|
|
432 | the likelyhood that there are additional problems where an invalid image |
|
|
433 | could cause gdk-pixbuf to crash or worse." |
|
|
434 | |
|
|
435 | =head1 BUGS/TODO |
|
|
436 | |
|
|
437 | Lots of functionality is missing. |
|
|
438 | |
|
|
439 | Pixbuf doesn't always honor G_BROKEN_FILENAMES, so accessing files with |
|
|
440 | names incompatible with utf-8 might fail. |
|
|
441 | |
|
|
442 | rotate on disk |
|
|
443 | lots of ui issues |
