GIMP's GEGL-based non-destructive effects let you re-edit Curves, mask grades selectively, and keep base pixels untouched — here's a worked setup, plus where the reversibility ends.
Decide between Script-Fu, Python-Fu, and headless batch for GIMP automation with a compact trade-off table and a validated Script-Fu resize-and-export example.
How GIMP layer masks work, how to add and paint one in the GUI, and how to automate the same steps with a Python-Fu script — plus the pitfalls that trip people up.
When you work on UI mockups, photo composites or multi‑page designs, the Layers dialog can quickly become a long list of individual layers that are hard to manage. Layer Groups let you bundle related layers into a collapsible container, simplifying visibility and selection.
Stop permanently deleting pixels. Learn how to use Layer Masks and Layer Groups in GIMP to create a non-destructive workflow that preserves your original image data.
Stop erasing pixels in GIMP. Layer masks hide parts of a layer reversibly using grayscale values — here's how they work, a two-exposure blend walkthrough, and the file-size and export trade-offs.
An architecture-level look at how GIMP's layer groups enable non-destructive editing through minimal metadata, clear trust boundaries, and runtime checks.
Learn how to use GIMP layer masks for non‑destructive portrait retouching. Follow a step‑by‑step vignette example, understand the trade‑offs, and keep your original pixels intact for maximum flexibility.
Architecture note on GIMP's GEGL pipeline: DAG-based pull model for constant memory, PDB trust boundary, operational checks for tile cache and color fidelity, failure modes (ICC clipping, OOM, ABI breaks) triggering redesign toward GPU compute or scene-referred compositing.
