Support for QOI

[andreasbaumann]

Preliminary support for the Quite Ok Image format, see https://qoiformat.org/.

Due to the simplicity of the format we don't need a library as such.

Currently there are some issues:

• performance: fread without too much buffering
• alpha channel handling might be a little bit too simplistic, especially not taking into account gamma or linear scaling
• background color is fix to white (the format doesn't define one and meh doesn't pass one to the individual decoders)

@zvezdochiot: Well, just thumbs down? You don't like the idea of QOI support or do you find my code terrible? :-)

[zvezdochiot]

@andreasbaumann . No need. https://github.com/richgel999/fpng

[andreasbaumann]

Ah. That's a valid point, speed. I didn't do it for that. QOI is just very very simple, that's the charm of it..
.. and I use meh for a long time now. :-)
Thanks for the link to fpng, didn't know about that..

[andreasbaumann]

Mmh. No activity? Ok, I assume meh is dead?
