Lossless FLIF encoding

[n00mkrad]

Hello, is there a lossless mode for FLIF, like there is for WEBP etc.?

https://github.com/FLIF-hub/FLIF:

FLIF is a lossless image format based on MANIAC compression. MANIAC (Meta-Adaptive Near-zero Integer Arithmetic Coding) is a variant of CABAC (context-adaptive binary arithmetic coding), where the contexts are nodes of decision trees which are dynamically learned at encode time.

Not sure what you ar aasking?

FLIF can be lossless or lossy, just like WEBP.

By default, it's lossy in Magick.NET, and the quality can be adjusted with the MagickImage.Quality property. This can be proved by encoding FLIF with quality 0, the image will have a tiny file size and noticably worse quality.

Now I want to know if a separate define is needed like for WEBP (img.Settings.SetDefine(MagickFormat.WebP, "lossless", true);, or if quality 100 means lossless.

You don't need a separate define. Setting the quality to 100 (the default value) means lossless. Did not know that FLIF also supported lossy encoding.
