Objective
Extend Script-Fu to include additional functions that help the user.
Key Concepts and Definitions
- Script-Fu: A scripting language based on Scheme
Additional Procedures
| Command | Purpose |
|---|---|
| (gimp-context-get-display) | Get the active display ID |
| (gimp-context-eraser-toggle) | Toggle the active tool to the eraser. |
| (gimp-context-eraser-paintbrush-toggle) | Toggle the active tool to the eraser and always return to the paintbrush |
| (gimp-context-get-eraser-active ) | Returns true if the Eraser Tool is active |
| (gimp-items-set-visible) | Set the visibility of a vector list of items |
| (gimp-context-get-brush-eraser-scale) | Returns the Paint Tool eraser scale |
| (gimp-context-get-brush-jitter) | Returns the Paint Tool jitter slider value |
| (gimp-context-set-brush-jitter) | Set all the Paint Tools jitter slider values |
Changes
- New Script-Fu Functions:
(gimp-context-get-display): Retrieves the active display ID. This ID can then be used with other display-related functions like(gimp-display-present display-id).(gimp-context-eraser-toggle): Toggles the active tool between the eraser and the previously active tool.(gimp-context-eraser-paintbrush-toggle): Toggles the active tool between the eraser and the paintbrush tool.(gimp-context-get-eraser-active): Returns 1 if the Eraser Tool is active or 0.(gimp-items-set-visible): Allows setting the visibility of a vector list of items in bulk. This can help streamline visibility management for layers, paths, or other drawable items.(gimp-context-get-brush-eraser-scale): Gets the Paint Tool eraser scale option to use with the eraser toggles. This allows all the painting tool presets to have a specific sized eraser. Erase pencil lines with a big eraser, cut into brush strokes with a smaller eraser.(gimp-context-get-brush-jitter): Gets the Paint Tool jitter option to use with the eraser toggles. This allows us to set the jitter for the eraser to be the same as the brush, in a hacky way.(gimp-context-set-brush-jitter): Sets all the Paint Tools jitter options to the same jitter value, eraser, paintbrush, airbrush, pencil.
Benefits
- These additional functions enhance the flexibility of Script-Fu, enabling users to toggle between tools, manage visibility across multiple items, and integrate display information into their scripts, leading to more powerful automation and customization.
