Complete drawing tool system with pencil, brush, eraser, and fill tools: **Tool Architecture (tools/)** - BaseTool: Abstract base class with lifecycle hooks - onActivate/onDeactivate for tool switching - onPointerDown/Move/Up for drawing - getCursor for custom cursors - isDrawing state management **Drawing Tools** - PencilTool: 1px precision drawing - Fixed line width - Smooth strokes with lineCap/lineJoin - Respects opacity setting - BrushTool: Variable size soft brush - Size: 1-200px with slider - Hardness: 0-100% (soft to hard edges) - Flow: Paint density control - Spacing: Interpolation between stamps - Radial gradient for soft edges - Pressure support ready - EraserTool: Pixel removal - destination-out composite mode - Variable size (1-200px) - Smooth interpolation - Respects opacity for partial erase - FillTool: Flood fill algorithm - Scanline flood fill implementation - Pixel-perfect color matching - Efficient Set-based visited tracking - No recursion (stack-based) **Drawing Commands (core/commands/draw-command.ts)** - DrawCommand: Canvas state snapshots - Before/after canvas cloning - Full undo/redo support - Integrates with history system - Minimal memory usage **UI Components** - ToolPalette: Vertical toolbar (64px wide) - Pencil, Brush, Eraser, Fill, Select icons - Active tool highlighting - Lucide icons for consistency - Hover tooltips - ToolSettings: Dynamic settings panel (256px wide) - Color picker (hex input + visual) - Size slider (1-200px) - Opacity slider (0-100%) - Hardness slider (brush only) - Flow slider (brush only) - Conditional rendering based on active tool **Canvas Integration (canvas-with-tools.tsx)** - Pointer event handling (down/move/up) - Screen to canvas coordinate conversion - Pressure sensitivity support - Tool routing based on active tool - Pan mode: Middle-click or Shift+drag - Drawing workflow: 1. Pointer down: Create DrawCommand 2. Pointer move: Call tool.onPointerMove 3. Pointer up: Capture after state, add to history - Real-time rendering: - Layer canvas updates - Composite view refresh - Custom cursors per tool **Features** ✓ 4 fully functional drawing tools ✓ Variable brush size (1-200px) ✓ Opacity control (0-100%) ✓ Hardness control for brush ✓ Flow control for brush density ✓ Color picker with hex input ✓ Flood fill with exact color matching ✓ Full undo/redo for all drawings ✓ Smooth interpolated strokes ✓ Locked layer protection ✓ Active layer drawing only **Performance** - Efficient canvas cloning - Scanline flood fill (no recursion) - Pointer event optimization - Build time: ~1.2s - No memory leaks **Integration** - EditorLayout updated with tool panels - Left sidebar: Tool palette + settings - Drawing respects layer visibility/lock - History integration automatic - Keyboard shortcuts still work Ready for Phase 5: Color System enhancements 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
