Layer Builder

Layer Decomposition App - paper

Quick usage

1. Drag and drop a PNG/JPG image (or click the image area to pick a file).
2. Set the output folder from the bottom bar.
3. Build your palette:
   • Extract from Image: auto-generates palette colors from the uploaded image.
   • Options from Image: auto-fills processing options based on image size.
   • Sort by Brightness: sorts current palette colors from dark to bright.
   • + / -: add or remove palette colors.
   • Click a color swatch to select it, then press Delete or Backspace (or -) to remove that specific color.
4. (Optional) Tune advanced options: NumSuperpixels, LLENeighbors, PixelNeighbors, Lm, Lr, Lu.
5. Click PROCESS & SAVE to export all generated layers to the selected output folder.

What color deletion does

Removing a color narrows the palette used for segmentation. This changes how pixels are grouped and can simplify output layers (fewer target colors, broader regions).

Build (Go + Wails)

1. Install Go (version 1.26+ recommended) and verify:
   • go version
2. Install Wails CLI:
   • go install github.com/wailsapp/wails/v2/cmd/wails@latest
3. Add Go bin path to your shell PATH (if needed), then verify:
   • wails version
4. From the project root, install frontend dependencies:
   • wails doctor
5. Build the app:
   • wails build
6. (Optional) Build with cleanup and no upx:
   • wails build -clean -upx=false
