PZP

Portable Zipped PNM

Overview

This is an experimental project to create a minimal PNG like header only image library that :

1. Is completely written in C and header-only
2. Supports 8bit/16bit Monochrome/RGB/RGBA files
3. Is as fast as possible in terms of image decoding speed
4. Offers some form of compression (this repo compresses slightly better than PNG)
5. Will hopefully be useful (to me personally) for my fast dataloader for training large neural networks
