Any programs that can open BMF and EMMA files?

Probably only the respective binaries . They are not common formats. The EMMA binaries in the link do not work for me .

BMF works, but worse than jpegxl on anime frame 00214.png (converted to bmp for input)


BMF max compression

JPEG-XL lossless max compression

@jay,

Rube Goldberg compulsion much?

You are making all these left turns to avoid just doing a simple right turn.

And we have a winner for that frame, for max compression. I found a working version here, it's probably older that the one used in that link. But this version works

I verified decompressed output is lossless

Not sure what you're using it for, but it takes a few minutes to compress and decompress 1 image. You can't really "view" them without decompressing them back to BMP . There is no commandline version either; you have to sit there and do them 1 by 1. Fun experiment, but probably not useful for real world



Here is a recap

00214.png from this thread was used as an 8bitRGB anime PNG test source
