Quick Start

harness-gimp bridge start
harness-gimp doctor
harness-gimp inspect input.jpg
harness-gimp resize input.jpg --width 1024 --height 768 --output resized.png
harness-gimp crop resized.png --x 0 --y 0 --width 800 --height 600 --output cropped.png
harness-gimp crop-center resized.png --width 800 --height 800 --output centered.png
harness-gimp export input.jpg output.webp
harness-gimp bridge status

All commands print one JSON object to stdout.

Note: layer-edit commands are most reliable on .xcf working files. Tip: prefer harness-gimp or harnessgg-gimp CLI entrypoints over python -m harness_gimp in mixed environments. Tip: bridge start --port ... persists the bridge URL for later commands; override anytime with HARNESS_GIMP_BRIDGE_URL. Set HARNESS_GIMP_STATE_DIR to customize where bridge state files are stored.
