An interface for viewing an image file with image-mode. Resizing an image is supported if ImageMagick 6 or 7 is installed. This interface deviates significantly with naming conventions used by image-mode to be more in alignment with conventional image editing tools.
If installed via MELPA then add these lines to your Emacs initialization file with your binding of preference.
(require 'casual-image) ; optional if using autoloaded menu
(keymap-set image-mode-map "C-o" #'casual-image-tmenu)Casual Image makes a number of opinionated changes to the naming of commands provided by image-mode.
The table below shows the mapping between names used by Casual to commands provided by image-mode.
| Casual Name | Image Mode Name | Notes |
|---|---|---|
| Zoom In | image-increase-size | “Zoom” is more commonly used. |
| Zoom Out | image-decrease-size | “Zoom” is more commonly used. |
| Original Size | image-transform-reset-to-original | Using a more concise name. |
| Fit to Window | image-transform-fit-to-window | Using a more concise name. |
| Rotate Clockwise 90°x | image-transform-set-rotation | Rotation command is absolute and only works in increments of 90°. |
| % of Original | image-transform-set-percent | Percent command is absolute in that it computes from the original image size. |
| Crop | image-crop | Command modifies image. |
| Fill | image-cut | Command modifies image. This command is primarily a fill operation, so is renamed appropriately. |
| Set Fill Color | image-cut-color | This variable supports a fill operation, so is renamed appropriately. |
| Save | save-buffer | Saves modified image file. |
| Save as | image-save | Command to save mutated image as another file via a mini-buffer prompt. |
| Rename | rename-visited-file | Renames the current image file. |
| Revert | revert-buffer | Reverts the current image file. |
| Scroll Up | image-previous-line | Rename to use arrow key direction. |
| Scroll Down | image-next-line | Rename to use arrow key direction. |
| Scroll Left | image-backward-hscroll | Rename to use arrow key direction. |
| Scroll Right | image-forward-hscroll | Rename to use arrow key direction. |
| Left Edge | image-bol | Rename to use better descriptive term. |
| Right Edge | image-eol | Rename to use better descriptive term. |
| Top-left | image-bob | Rename to use better descriptive term. |
| Bottom-right | image-eob | Rename to use better descriptive term. |
| Previous Image | image-previous-file | Visit the preceding image in the same directory as the current file. |
| Next Image | image-next-file | Visit the next image in the same directory as the current file. |
| Mark Image | image-mode-mark-file | Mark the current file in the appropriate Dired buffer(s). |
| Unmark Image | image-mode-unmark-file | Unmark the current file in the appropriate Dired buffer(s). |
| Copy filename | image-mode-copy-file-name-as-kill | Push the currently visited file name onto the kill ring. |
If ImageMagick (version 6 or 7) is installed, Casual Image can resize an image using it. The Transient casual-image-resize-tmenu is a streamlined interface to the ImageMagick -resize function.
Note that if the image file has been modified, the resize interface will be disabled. Save the image file before resizing.
- (g) Geometry - ImageMagick specifier for the resize geometry.
- (o) Output to another file - If enabled, then the user will be prompted for a different output file, else it will irreversibly update the current image file.
- (t) Type - Specify if adaptive or interpolative resizing should be used. If nothing is specified then standard resizing is used.
By enabling “Use Unicode Symbols” from the Settings menu, Casual Image will use Unicode symbols as appropriate in its menus.
If you enjoy using Casual Image, consider making a modest financial contribution to help support its development and maintenance.
