coco-maskapi

An unofficial TypeScript port of Coco API's maskApi.c (reference).

Context

Coco API uses a modified version of Run Length Encoding (RLE) to efficiently store image masks. RLE data is further compressed via a modified version of LEB128 (which can be inuitively considered LEB32).

coco-maskapi aims to bring this flavor of mask compression/encoding to web browsers, favoring Canvas ImageData as the data source and target.
