- Tumme provides for simple viewing of thumbnails if image files. It
-also provides viewing of the original file, sized or in full size,
-inside Emacs or in an external viewer.
-
- Tumme aims to be both easy to use for a beginner but also powerful
-and useful for an experienced user.
-
- To try out Tumme, mark some image files in Dired and type @kbd{C-t
-d} (@code{tumme-display-thumbs}). With point in the thumbnail buffer,
-type @kbd{RET} (@code{tumme-display-thumbnail-original-image}) to
-display a sized version of it. Use the keys to move around in the
-buffer. For easy browing, type @kbd{SPC}
-(@code{tumme-display-next-thumbnail-original}) to advance and display
-the next image. Typing @kbd{SPC}
-(@code{tumme-display-previous-thumbnail-original}) backs up to the
-previous thumbnail and displays the image.
-
- If you want to see the image in its original size, either provide a
-prefix argument (@kbd{C-u}) before pressing @kbd{RET}, or type
-@kbd{C-return} (@code{tumme-thumbnail-display-external}) to display
-the image in an external viewer.
-
- If you find in image that you want to delete, type @kbd{d}
-(@code{tumme-flag-thumb-original-file}) and the file will be flagged
-for deletion in the dired buffer. If you just want to delete the
-thumbnail image from the thumbnail buffer, type @kbd{C-d}
-(@code{tumme-delete-char}).
-
- More advanced features include commands for using ``tags'' (labels,
-or categories) to tag image files and to search for image files with a
-certain tag.
-
- The tags put on image files are stored in a database file and can be
-used for marking image files. For example, you can let Tumme mark all
-files in the current directory tagged with the tag `flowers'. To tag
-image files, mark them in the dired buffer and type @kbd{C-t t}
-(@code{tumme-tag-files}). To mark files having a certain tag, type
-@kbd{C-t f} (@code{tumme-mark-tagged-files}).
-
- Tumme also provide simple image manipulation commands, like rotating
-thumbnails and original image files.
