Skill

batch-process

Apply one operation across a folder of images using GIMP's headless console — resize, crop, format-convert, flatten, watermark, etc. Use when the user wants to bulk-process images and ImageMagick alone isn't enough (e.g. needs a GIMP-only filter or PSD/XCF support).

Batch Process

Stub orchestrator — composes a Script-Fu loop and hands off to run-script-fu.

Inputs

input_glob — e.g. ~/Pictures/raw/*.jpg

output_dir

operation — one of: resize, crop, format-convert, flatten, watermark, custom

Operation-specific args (e.g. width, height, format, watermark_path)

Steps

Verify the saved profile exists; otherwise call onboard.

Resolve the input file list with ls/find. Bail if empty.

For each operation, generate the Script-Fu body:

resize: gimp-image-scale
crop: gimp-image-crop
format-convert: gimp-file-load → file-<fmt>-save
flatten: gimp-image-flatten
watermark: load image, load watermark as layer, position, flatten, save
custom: prompt for the inner Script-Fu expression

Wrap in (let loop ...) over the file list, ending with (gimp-quit 0).

Hand the full script to run-script-fu via script_path.

Report counts: succeeded / failed / skipped.

Notes

Prefer ImageMagick (magick) for simple resize/format conversion — faster, no GIMP startup cost. Only use this skill when the operation actually needs GIMP.

For very large batches, split into chunks of ~500 to avoid Script-Fu memory bloat.
