Link: Updated 02/17/2019 windows binaries / source code on GitHub

12/17/2018: v0.1.6 very high compression added. This version is still fast with a good neatness.
10/09/2018: I have developped NHW Neatness Metrics to measure neatness of images.
An Image Comparison of NHW and x265 Sample 512x512 test images
Here are the 3 test images compressed with this new version 0.1.6:
Remark: The entropy coding schemes are not totally optimal for now, I have the fast ideas to improve them, and so we can save 2.5KB per .nhw compressed file in average.
Next steps are: coding the other (lower and higher) quality settings, lower quality setting is rather complex...
