Don't scale chroma subsampled images to sizes that don't align with the subsampling (#1872). 2021-10-03T21:41:02Z Carl Hetherington cth@carlh.net 2021-10-03T19:22:14Z urn:sha1:969906f2dd6c5c144781861f53e2a0f6baefb9a3 There's a slightly odd effect when scaling e.g. YVU420 images to odd and then even widths - there's a small but visible luminance shift. I don't know why this happens, but keeping the scaling sizes locked to the subsampling seems to help. Differentiate requested and actual crop. 2021-10-03T21:41:02Z Carl Hetherington cth@carlh.net 2021-10-03T18:53:44Z urn:sha1:70b72b53eab0f247eb4dc605a2d669d4adb4e469 This is so we limit cropping to what is possible considering chroma subsampling.
