Image Rotate (new node): rotate, zoom and reposition an image inside a
definable canvas. Free or fixed (45 degree snap) rotation, centre-zero
angle slider (CCW left, CW right), exponential centre-zero zoom
(-100 = 0.25x, +100 = 4x), percent-based XY placement, and
transparent/black/white background fill. An optional mask input rides
the identical matrix so it stays registered to the image. Canvas W/H
inputs default to 0, meaning "match the incoming image".
Remove Background Pro: rotation block added at the bottom of the
settings (enable toggle, free/fixed method, angle slider, XY
placement). Applied after removal so rembg always segments the upright
image; the canvas stays at the original size and image, mask,
masked_image, mask_bw and passthrough are all warped by the same
matrix.
New transform_utils module keeps the rotate/zoom/offset math identical
across both nodes. js/image_transform.js snaps the angle slider to 45
degree steps in fixed mode and hides the rotation widgets until the
toggle is on; Python snaps too, so the result is correct regardless of
frontend version.
New Nodes:
- Mask Composite Pro 2X: combine 2 masks with per-mask blur/grow-shrink/opacity, screen blend, output selector, invert
- Mask Composite Pro 6X: combine up to 6 masks with same features
Updates:
- Inpaint Mask Pro: added expand/shrink, removed SEGS (simplified to image + mask), inpaint_mask now required, multi-color overlay
- Blur Pro: type-specific sliders marked as advanced for cleaner default view
- Widget visibility uses Python "advanced" flag for new ComfyUI frontend compatibility
- Added CLAUDE.md with versioning and registration rules
- Bump to v2.1.1, 40 nodes total
The requirements.txt was missing opencv-python-headless, which is
imported by 7 node files at the top level. When cv2 is not installed,
the entire module fails to load silently, causing KeyError for all
nodes including SeedLock.
