erlpixels

Based on Pixels

Erlang NIF to read image data from PNG and JPEG files.

This code is fully derived from the Elixir https://github.com/arjan/pixels library via a literal conversion of the Elixir parts to Erlang.

The original Elixir Pixels library should also be fully usable from Erlang.

This version exists solely because I couldn't bring myself to add an Elixir dependency to erlguten. Thank you Joe, RIP

For PNG images, it uses the lodepng C library.

For JPEG images, it uses the ujpeg C library. Progressive or lossless JPEG files are not supported by this library.
