Here are some very few results on some images (bitmap color 512x512):




Original: Lighthouse1 - bitmap color 786486octet

Compressed .nhw file: Lighthouse1.nhw 45934octet

Original: Birds5 - bitmap color 786486octet

Compressed .nhw file: Birds5.nhw 73101octet

Original: Butterflies2 - bitmap color 786486octet

Compressed .nhw file: Butterflies2.nhw 65968octet

Here are very few sample images, do not hesitate to test it on other images (bitmap color 512x512 for the moment) by downloading the win32 binaries linked above.


Remark: The entropy coding schemes are not totally optimal for the moment, and normally we can save or win 2KB-2.5KB in average on the compressed .nhw files.-These improvements will have to be done...-
