32 | ;; This package create two new mode: thumbs-mode and | |
33 | ;; thumbs-view-image-mode. It is used for images browsing and viewing | |
34 | ;; from within emacs. Minimal image manipulation functions are also | |
35 | ;; available via external programs. | |
36 | ;; | |
37 | ;; The 'convert' program from 'ImageMagick' | |
38 | ;; [URL:http://www.imagemagick.org/] is required. | |
39 | ;; | |

43 | ;; This is version 2.0 | |
44 | ;; | |
45 | ;; USAGE | |
46 | ;; | |
47 | ;; Type M-x thumbs RET DIR RET to view the directory DIR in Thumbs mode. | |
48 | ;; That should be a directory containing image files. | |
49 | ;; from dired, C-t m enter in thumbs-mode with all marked files | |
50 | ;; C-t a enter in thumbs-mode with all files in current-directory | |
51 | ;; In thumbs-mode, pressing <return> on a image will bring you in image view mode | |
52 | ;; for that image. C-h m will give you a list of available keybinding. | |
