pub fn fit(
rgba: &[u8],
width: u32,
height: u32,
max: u32,
) -> (Vec<u8>, u32, u32)Expand description
rgba, width × height, resampled to at most max pixels a side with
its aspect kept, or as it is when it already fits. Each new pixel is the
area-weighted average of the pixels under it, in premultiplied alpha so a
transparent pixel lends no color.
