Create a FLIF file with a 256 color palette. #555

Closed QLaHPD closed 3 years ago

QLaHPD commented 4 years ago

How to create a FLIF file with a 256 color palette, where the input file will be a PNG with a 256 color (8 bit) palette? I tried to use the "--keep-palette" option, but the output file is always in RGBA format (32 bits).

FLIF development has stopped since FLIF is superceded by FUIF and then again by JPEG XL (https://jpeg.org/jpegxl/index.html), which is based on a combination of Pik and FUIF. A royalty-free and open source reference implementation of JPEG XL is available on GitLab.

So does this mean that in the latest version of FLIF it is not possible to use these settings?

bjorn3 commented 4 years ago

I don't now if the decoder can create PNG's with 256 color palette. FLIF itself should support color palette's though.

Do you know if there is a way to set the bit depth in the current implementation (in the encoder)?

bjorn3 commented 4 years ago

I think the encoder just takes the bit depth of the input image.
