}

Result of parsing an AVIF file. Contains AV1-compressed data.

Fields

primary_data: *const u8

AV1 data for color channels

primary_size: usize

alpha_data: *const u8

AV1 data for alpha channel (may be NULL if the image is fully opaque)

alpha_size: usize

premultiplied_alpha: u8

0 = normal, uncorrelated alpha channel 1 = premultiplied alpha. You must divide RGB values by alpha.

if (a != 0) {r = r * 255 / a}
