mike 8dfe7775ea edit_api.py:
•
SAM2 fix — switched to SAM2ImagePredictor with a generous bbox (5% margin) instead of points. Bbox-based SAM2 captures the full subject including hair, glasses, and sandals since it doesn't clip with negative-point interference
•
Non-destructive remove-bg — writes <stem>.nobg.png sidecar, original file untouched; registers sidecar in DB under same group
•
New /images/{filename}/duplicate endpoint — copies file with a fresh timestamp name, same group
car.html:
•
sam2RemoveBg() — switches viewer to sidecar URL, auto-enables checkerboard; original file never modified
•
restoreBg() — purely client-side, reverts viewer to original URL (no API call, no file change)
•
Gallery cycling frozen while studio is open (guard in startGroupCycle interval callback)
•
Main page scrollbar hidden when studio opens (body.overflow = hidden), restored on close
•
Delete — two-step inline confirmation: first click arms the button red ("Confirm delete"), second click deletes; stays in studio and navigates to the next image; only closes if it was the last image in the group
•
Duplicate button in Info tab — copies image into same group and navigates to the duplicate immediately

edit_api.py — headless throughput API for Qwen-Image-Edit Rapid-AIO (v23 Q8 GGUF)
running on top of a local ComfyUI server.
Flow per request: image + prompt -> upload to ComfyUI -> inject into the
workflow graph -> queue -> poll until done -> return the edited PNG.
Run ComfyUI first (run_comfyui.sh), then this service (start_api.sh).
