resize

A new image of width by height. NEAREST is fastest, BILINEAR is the default and is smooth when enlarging, and BOX is the one to shrink with. Alpha is not premultiplied, so the colour of transparent pixels bleeds into their neighbours. An invalid image or size gives an empty image.

image := make_image(100, 100, .RGB8);
defer deinit(*image);

thumb := resize(image, 25, 25, .BOX);
defer deinit(*thumb);
assert(thumb.width == 25 && thumb.height == 25);

resize :: (
    image: Image,
    width: s32,
    height: s32,
    filter := Resize_Filter.BILINEAR
) -> Image
