Roadmap

Short term:

• Do lots of TODOs.
• Implement coroutines, for streaming decoding.
• Finish the GIF decoder.
• Write the PNG decoder.
• Write the JPEG decoder.
• Write the PNG encoder.
• Design an image API that works with all these, including animated GIF.
• Write some example programs, maybe cpng a la cjpeg and cwebp.
• Add compatibility tests, benchmarks, code size comparison.
• Release as open source.

Medium term:

• Write the BMP/ICO decoder.
• Write the TIFF decoder.
• Write the WEBP decoder.
• Write the JPEG encoder.
• Get to 100% compatibility, on a large web crawl corpus, with libpng etc.
• Optimize the codecs; benchmark comparably to libpng etc. Might require SIMD.
• Ensure code size compares favorably to libpng etc.
• Fuzz it, both for crashers and for different output to libpng etc.

Long term:

• Ship with Google Chrome: safer code, smaller binaries, no regressions.
• Ship a version 1.0: stabilize the language and library APIs.
• Write a language spec.
• Generate Go code.
• Generate Rust code.

Very long term:

• Other file formats? Fonts? PDF? Audio? Video?
• Other image operations? Image scaling that's both safe and fast?
