- Implemented feather brush tool in the brushRaster module, allowing for feathered edges in brush strokes. - Added new FeatherControls component for UI adjustments of feather settings including size, radius, strength, and smoothing. - Updated brush preview logic to accommodate feather tool alongside existing brush and eraser tools. - Enhanced layer rendering to support feather mask previews and interactions. - Introduced blending logic for feathered strokes to mix blurred mask values with original pixels. - Added unit tests for feather blending functionality and tool keybindings. - Updated cursor handling to reflect feather tool usage.
Image Studio
Image Studio is a Bun + React image editor prototype. It uses a command-driven architecture for document and editor state, a canvas/WebGL renderer layer, and a lightweight React UI for tools, layers, imports, exports, and shortcuts.
Features
- Import images into an artboard
- Save and open versioned project files with embedded, project-owned assets
- Automatic local recovery snapshots after document changes
- Export the active artboard as PNG
- Layer selection and layer sheet
- Select, transform, pan, brush, eraser, chroma key, and magic wand tools
- Mask-edit workflow support
- Undo/redo through command history
- Keyboard shortcuts and pointer/wheel canvas input
Tech stack
- Bun for runtime, package management, tests, and builds
- React 19
- Tailwind CSS 4
- shadcn/ui-style component utilities
- TypeScript
Getting started
Install dependencies:
bun install
Start the development server:
bun dev
To start Image Studio together with the local headless ComfyUI server:
bun run dev:full
The combined launcher reuses a ComfyUI server already listening at
http://127.0.0.1:8188. Otherwise, it starts the existing local ComfyUI
installation and stops that process when Image Studio exits. Its paths and
address can be overridden with the COMFYUI_BASE_DIR, COMFYUI_SOURCE_DIR,
COMFYUI_PYTHON, COMFYUI_MODEL_PATHS_CONFIG, COMFYUI_HOST, and
COMFYUI_PORT environment variables.
Build for production:
bun run build
Run the production server:
bun start

Project structure

Architecture notes
State changes flow through commands. React components present state and dispatch user intent, while document/editor mutations are handled by command modules. The renderer consumes document and editor snapshots to draw the canvas and overlays without owning application state.
