    Easy way for BMF to png

    I have a lot of png drawings that i wish so save as small as possible.
    i have tried optimizing the png but converting to bmf still reveals smaller files
    Sometimes saving the raw BMPS inside 7-zip reveals better compressions then bmf)

    however since no program can display bmf i wish to make a easy batch file that can convert bmf back to png

    i tried converting bmf back to bmp with the bmfc util. and then using pngout to make a png file.BUT
    BMFc outputs RLE encoded BMP files and pngout cannot deal with that

    MM + bliz is a very good BMP compressor... especially for big BMP's, far better than 7z. You can also try other BWT compressors instead of bliz : dark, grzip, NZ, Sbc, ...)
    (MM = multimedia tool from Bulat / bliz = I guess you know that )
    For comparison see http://www.metacompressor.com/uploads.aspx (file

    I tried

    MM it failed detection in alle the files (its black and white pictures in BMP)
    BLiz
    RZM
    Nanozip (optim1, optim2 and CC)

    none of thme compared to 7-zip LZMA

    Yet BMF is still about half the size of the 7-zip archieve

    just to give some feedback.

    I will try xnviem as a conveter next

    if its just black & white and you need accessing i can suggest Jbig2 in PDF or JB2 in DJVU both in "lossless" mode.. (i can do it for you..) then the resulted file are viewable directly..

    or if you care less about details i often use "cpctool" before it refine image making it more compressable (specially if its a scaned book or such) (even this i can do it for you)

    or use "lossy" mode to gain more compression (better than any compressor) in pdf or djvu..

    btw .. i use these methods to produce smaller files and i view it on my Pocket PC.. so its much practical..
