;;; Commentary:
|
|
|
|
;; NOTE: This library was made obsolete in Emacs 29.1.
|
|
;; We recommend using `M-x image-dired' instead.
|
|
;;
|
|
;; --------------------
|
|
;;
|
|
;; 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 categorize and tag
|
|
;; your images, use image-dired.el
|
|
;;
|
|
;; The 'convert' program from 'ImageMagick'
|
|
;; [URL:https://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
|
|
;; for Emacs and the GNU project.

;; This is version 2.0

|
|
;; 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 an image will bring you in image view
|
|
;; mode for that image. C-h m will give you a list of available keybinding.
