pub fn target_size(w: u32, h: u32, max: u32) -> (u32, u32)Expand description
Target size for a w x h image with short-side limit max.
Nothing changes unless the long side exceeds max. Then the short side
becomes max (landscape fixes the height, everything else the width) and
the other side follows with truncation. A wide image whose short side is
already under max is therefore scaled up, as in Eagle.
