QOI imlementation in pure V.
QOI is fast. It losslessy compresses images to a similar size of PNG, while offering 20x-50x faster encoding and 3x-4x faster decoding.
QOI is simple. The reference en-/decoder fits in about 300 lines of C. The file format specification is a single page PDF.
import vqoi
import os
fn main() {
width := 500
height := 400
rgba := [][4]u8{len: width * height, init: [u8(255), 0, 0, 255]!}
metadata := vqoi.ImageMetadata{u32(width), u32(height), .rgba, .srgb}
image := vqoi.Image{rgba, metadata}
data := vqoi.encode(image)
os.write_file('hello.qoi', data.bytestr()) !
decoded_image := vqoi.decode(data) !
assert decoded_image == image
