Rust Image Release Notes

Rust image aims to be a pure-Rust implementation of various popular image formats. Accompanying reading/write support, rust image provides basic imaging processing function. See README.md for further details.

Known issues

• Interlaced (progressive) or animated images are not well supported.
• Images with n bit/channel (n ≠ 8) are not well supported.
