Why image-stitch?
Streaming friendly
Produce PNG chunks as they are generated so that you never buffer entire gigabyte-scale spritesheets in memory.
Layout aware
Compose rows, columns, and responsive grids with automatic padding that respects alpha transparency.
Typed & tested
Written in modern TypeScript, bundled for browsers, and verified by more than one hundred unit tests.
No canvas required
Decode, transform, and rebuild PNGs in pure JavaScript so you can run on the server, worker threads, or edge runtimes.
Get started
Install via npm install image-stitch and follow the step-by-step guides that walk through Node.js scripts, browser usage, and streaming pipelines.
