Flow-Like Color Extraction Node

Flow-Like WASM node package for extracting dominant colors from an image file.

Node

Image Palette

Inputs:

• image_path: FlowPath to a PNG, JPEG, GIF, WebP, BMP, or TIFF image
• color_count: maximum number of colors to return, from 1 to 64

Output:

• colors: string array of #RRGGBB hex colors, sorted by dominance

The node reads the image through Flow-Like storage, decodes it in WASM, samples opaque pixels, and uses median-cut quantization similar to palette/color-thief style extractors.
