Quite OK Image format encoder/decoder written in Zig

The isQOI
function expects the Header
type to contain a .size
field, yet it doesn't.
I expect it to be fixed by replacing header.size
with header.width * header.height
at line 74, but I don't know for sure than this is how QOI works.
./zig-qoi/src/qoi.zig:74:46: error: no member named 'size' in struct '.qoi.Header'
return (bytes.len >= Header.size + header.size);
^
It really only checks that the header is correct and that the sequence of bytes isn't longer than the header claims.
Since decoding a QOI image only takes one pass, this is probably the correct implementation. However, the documentation makes no mention that isQOI doesn't guarantee that its input actually is a Quite Okay Image.
I'm newbie for zig so it may my misunderstanding, but it seems that this encoder implementation interprets the input buffer as RGBA packed pixel images regardless Header.format
. If it's true, this implementation can't accept 3-channel images.
Does this supports RGB buffer for input?
This could be ported phoboslab/qoi#11.
