    BMF is not binary lossless NOR picture lossless

    i just tested the (for me) new version of bmf

    my first picture was a 16 colors greytone scanning of some text.

    The white 256/256/256 palette entry was changed to 240/240/240 after decompression from bmf.

    as i don't now russian maybe someone here can address this issue for the developer.

    I suppose you can do it by yourself. I'm sure that Dmitry Shkarin knows english better than a lot of people here How do you think he wrote the supplied readme file?

    There're just too many options and weird defaults.
    But I still managed to use it as a lossless coder -
    see http://ctxmodel.net/files/mix_test/mix_test_vA1.rar (test2.bat)
    However, its certain that it doesn't preserve the image header
    and encoding, and there's also a lossy mode too.

    i was only using it as a lossless encoder.

    but i think the erros comes from the 16 values increas in palletter colors

    ege.
    entry 1 = 0/0/0
    entry 2 = 16/16/16
    entry 3 = 32/32/32
    ...
    entry 13 = 208/208/208
    entry 15 = 224/224/224
    entry 16 = 256/256/256 changed to 240/240/240

    OK, I've just sended the letter to Dmitry with a couple of suggestions regarding the BMF. I've also invited him here so let's see what will happen.
