* Magic Eraser and Background Eraser engine commands paint.magicEraser erases the wand region (tolerance, anti-alias, contiguous, sample all layers, opacity) to transparency, tile by tile in parallel; paint.backgroundEraser erases colours similar to the one under the brush hotspot (continuous / once / background swatch sampling, discontiguous / contiguous / find-edges limits, tolerance, protect foreground colour). Both compare and erase in the layer's own channels at any depth, respect the selection, turn the Background into Layer 0 like Photoshop, and are one undo step. The Magic Eraser paints the background colour on layers with locked transparency.

Options bars: Magic Eraser tolerance, anti-alias, contiguous, sample all layers and opacity; Background Eraser sampling toggles, limits, tolerance and protect foreground colour. The Background Eraser cursor always shows its sampling hotspot. Icons are derived from Lucide's eraser (ISC), recorded in ATTRIBUTION.md.

New engine module canvas_geom applies the canvas map to all non-pixel geometry. 90°/180°/flip turns remap every pixel surface exactly (incl. type/shape/smart/fill caches and smart filter masks) and move geometry through the matching affine; guides swap orientation under 90° turns; rect/ellipse/line live shapes stay live; gradient fill angles follow. Canvas Size/Crop/Trim translate geometry (shapes re-render for the new canvas), Image Size scales it and re-renders vectors, Arbitrary rotation also moves unlinked vector masks and document marks. Layer effect angles stay (Global Light), as in Photoshop. Tests compare the CPU composite of a rotated document (type, shapes, vector mask, smart object) against the rotated flattened original, also after re-rendering everything from geometry, at 8/16/32-bit RGB, CMYK and Gray.

The ignored bench prints a phase breakdown. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> |
