Pixel Utility Functions

pixel-utils is a JavaScript/TypeScript library providing minimalist utility functions for pixel manipulation. As of version 0.9.0, it offers conversions between raw, RGB, and RGBA pixel formats, functions for handling 'no data' values, pixel iteration, selection, and transparency adjustments. The library is optimized for speed and supports optional mutability for memory-preserving operations. A key differentiator is its ability to handle raw image data (not limited to 8-bit 0-255 RGBA) and arbitrary image layouts, thanks to integration with the xdim library. While actively developed with frequent minor updates, the project maintains a 'beta' status, indicating that function signatures are subject to change without strict adherence to semantic versioning for breaking changes. Core assumptions involve pixel formats as arrays of numbers (0-255 for RGB/RGBA, arbitrary for raw) and specific conventions for alpha and 'no data' values.
