Hello,

Just a quick message in the case if the IETF would be studying the NHW
Project, for fair comparison, notably at very high compression, the entropy
coding schemes of the NHW Project are not optimal for now, and we can save
in average 2.4KB per .nhw compressed file.

Also, yes the NHW Project is only for 512x512 image size for now, I am
currently spending my (limited) time on improving the codec and coding very
high compression.But if you are interested in the NHW Project, it would be
so great if you can propose me a contract, to adapt it to any image size
for example, and other things!

Thank you very much!
Cheers,
Raphael Canut
