PNG Encode Mini

Tiny PNG writing utility, without any dependency on zlib or libpng, useful when only basic functionality is required.

Exposes a single method write which takes RGBA pixel-data, with width and height arguments.

Tests

Currently the tests use ImageMagick convert and compare commands to validate the output images can be read.

Further Work

While this crate is intentionally kept small, there are some possible additions.

• Writing grey-scale images.
• Writing RGB images (without an alpha channel).
