;;; Commentary:
|
|
|
|
;; This package create two new modes: thumbs-mode and thumbs-view-image-mode.
|
|
;; It is used for basic browsing and viewing of images from within Emacs.
|
|
;; Minimal image manipulation functions are also available via external
|
|
;; programs. If you want to do more complex tasks like categorise and tag
|
|
;; your images, use image-dired.el
|
|
;;
|
|
;; The 'convert' program from 'ImageMagick'
|
|
;; [URL:http://www.imagemagick.org/] is required.
|

;; Thanks: Alex Schroeder <alex@gnu.org> for maintaining the package at some
|

;; time. The peoples at #emacs@freenode.net for numerous help. RMS

;; USAGE
|

|
|
;; Type M-x thumbs RET DIR RET to view the directory DIR in Thumbs mode.
|
|
;; That should be a directory containing image files.
|
|
;; from dired, C-t m enter in thumbs-mode with all marked files
|
|
;; C-t a enter in thumbs-mode with all files in current-directory
|
|
;; In thumbs-mode, pressing <return> on a image will bring you in image view
|
|
;; mode for that image. C-h m will give you a list of available keybinding.
