- fix WebP export silently producing PNG when background is non-transparent
- fix autosave not converting blob: URLs inside image-type canvas objects
- fix project load not resetting selection/crop/clipboard state
- fix rotateCanvas not updating object rotation attributes
- fix flipCanvas not negating object rotation attributes
- fix line shadow props overridden by effect spread ordering
- fix "outside" stroke position rendering same as "center"
- add missing pencil tool keyboard shortcut (N)
- remove misleading resample dropdown from image resize dialog
- fix E2E autosave tests for production builds (no Vite dynamic imports)
- fix color picker test case sensitivity (CSS uppercase vs DOM text)
- add 4 unit tests for rotation attribute transforms
Canvas rendering:
- Fix Konva filter application order (filters before cache)
- Implement 6 missing filters (motionBlur, radialBlur, surfaceBlur, vignette, grain, sharpen)
- Implement exposure, vibrance, warmth adjustments as custom Konva filters
- Apply layer blend modes via globalCompositeOperation
- Apply object effects (drop shadow, outer glow, stroke) to all shapes
- Mount SmartGuidesOverlay during move tool drag
- Clip pixel grid to visible viewport (200-line cap for performance)
Store logic:
- resizeImage now scales all objects proportionally (points, radii, fontSize)
- rotate/flip/trim handle line/arrow points arrays and center-based objects
- applyCrop creates cropped source image via offscreen canvas
- invertSelection creates mask from bounds when no mask exists
- cutObjects uses single atomic set() to prevent race conditions
- sendToBack respects layer ordering in multi-layer documents
- Add batchNudge() and commitHistory() for undoable nudge operations
- Add updateLayerThumbnail() method
Tool hooks:
- Fix clone stamp/dodge/burn perf (toDataURL only on mouseUp, not every move)
- Fix magic wand zoom/pixelRatio with explicit stage.toCanvas() viewport
- Fix eyedropper sampling with unzoomed canvas export
- Fix selection tool stale closure via isDrawingRef
- Implement polygonal lasso (click-to-place vertices, double-click to close)
- Implement selection subtract mode (geometric and mask-based)
- Implement gradient live preview during drag
- Fix transform/move tool to persist changes and handle ellipse/polygon/star
UI wiring:
- Mount rulers and guidelines in editor page
- Wire histogram with live canvas imageData
- Wire autosave recovery with blob-to-dataURL conversion
- Wire fill dialog to Shift+Backspace shortcut
- Wire eyedropper and transform options to options bar
- Fix history panel undo/redo button reactive state via useSyncExternalStore
- Fix layer row name click to select layer (timer-based click/dblclick)
- Fix zoom animation coordinate drift with progressive store sync
- Fix copy merged to use Konva stage composite export
Tests:
- 49 new unit tests (store fixes + konva filters)
- 8 new E2E test files with 39 test cases
1. Export dialog (Ctrl+Shift+S): replaced react-hotkeys-hook handler with
a capture-phase keydown listener on window so the browser's native
"Save Page As" dialog is intercepted before it can fire.
2. Text tool: created useTextTool hook that spawns an inline textarea
overlay on canvas click, commits the text as a Konva Text object on
blur/Enter, and wired it into the useActiveToolHandlers dispatcher.
3. Undo (Ctrl+Z): removed the 500ms debounce from zundo's handleSet.
The debounce caused a race where calling undo before the timer fired
would discard the future-states stack, making undo appear to do
nothing. The equality function (keyed on _historyVersion) already
prevents intermediate states from being recorded, so the debounce
was redundant.
Implement Agent 7 features for the image editor:
- History panel with undo/redo list, action icons, and state jumping
- 51+ keyboard shortcuts via react-hotkeys-hook (tools, modifiers, clipboard)
- Export dialog with PNG/JPEG/WebP format, quality, resize, clipboard copy
- Navigator minimap with viewport rectangle, drag-to-pan, zoom slider
- Autosave/recovery system with localStorage and recovery banner
- Project save/load (.snapotter JSON format)
- Unsaved changes warning via beforeunload
- Paste from system clipboard support
