Hi all
Longtime lurker, first time poster. I recently spent a number of days getting up to speed on zpaql and how to write a zpaq image compression config for grayscale images. I could not find any information online about how to actually get started writing a zpaql config for 2D image compression, so I wrote up an intro on my blog:

With this config lena512.pgm would compress down to 138 kB with minimal CPU usage (for a zpaq configuration).
cheers
