Ensure consistent border extension by rounding uv_crop_* at image creation time. Where it was rounded problems could arise with the right and bottom extensions. When padding = 32, y_width = 64, and y_crop_width = 63: (padding + width - crop_width + 1) / 2 32 + 64 - 63 + 1 should equal 32 *but* 32 + 1 + 1 equals 34 giving a right buffer of 17 instead of 16. By calculating uv_crop_* earlier we round up at the appropriate time and for the same values: (y_crop_width + 1) / 2 63 + 1 / 2 64 (padding / 2) + uv_width - uv_crop_width 16 + 16 - 16 16 Change-Id: If866cd1b63444771440edb1432280ac83875969b |
