dcpomatic/src/lib/image.cc, branch v2.14.44 DCP-o-matic DCP tools https://git.carlh.net/cgit/dcpomatic/atom?h=v2.14.44 2020-11-19T21:08:21Z Hack to fix image luminance when cropping subsampled images (#1872). 2020-11-19T21:08:21Z Carl Hetherington cth@carlh.net 2020-11-19T21:07:39Z urn:sha1:2456409a8db781d9ef505fc9e5f9290276ce6807 Without this the luminance varies slightly as you crop by odd and even amounts (for YUV420 images). Fix cropping of subsampled images. 2020-11-17T08:59:30Z Carl Hetherington cth@carlh.net 2020-11-16T23:00:50Z urn:sha1:27c0e43d75218b926068fff3d6d1364b476e56ff The calculations for how to crop subsampled components of YUV images were wrong, causing strange effects like misregistration of colour components in cropped images. Should fix #1872. Add some lrintf() calls to be sure. 2020-11-16T23:18:02Z Carl Hetherington cth@carlh.net 2020-11-16T22:58:53Z urn:sha1:451e5465bbd10827dafe76b35704102e589c0980 Use 64-byte alignment for aligned image memory. 2020-11-16T23:17:52Z Carl Hetherington cth@carlh.net 2020-11-16T22:56:11Z urn:sha1:cdf9ebe4a827d8d2d6d89e34bad0c976b04834b7 FFmpeg uses this values if AVX512 is available, and with only 32-byte alignment I am seeing strange scaling effects whereby crop_scale_window_test7 gives black bars down the right side of cropped images (when run on an i7 7700). Fix incorrect images when cropping without stretch. 2019-11-16T21:46:39Z Carl Hetherington cth@carlh.net 2019-11-04T15:38:14Z urn:sha1:ed4fc06db6957b2b63b2400a737f47c18a1003be Always overallocate images so that Image::crop_scale_window is always safe from over-reading buffers. Relates to #1654 and probably #1653. Backported from 7b0372776ac4da6a8e4ff29f41a4f08b9b4de506 in v2.15.x. Fix "cannot handle pixel format 26 during make_transparent()" (part of #1545). 2019-05-03T14:00:41Z Carl Hetherington cth@carlh.net 2019-05-03T14:00:19Z urn:sha1:46df210e1c25c3cdae664390efac8e60714ad635 Fix or remove several broken pixel formats in Image::fade and add 2019-04-25T15:19:25Z Carl Hetherington cth@carlh.net 2019-04-25T15:19:25Z urn:sha1:11efa93e15b694b8ea6f0a2bc68c87503cc570bb unit tests for the remainder. Fixes #1532. Fix R/B swap with as_png(); support as_png() for any pixel format. 2019-03-12T23:16:03Z Carl Hetherington cth@carlh.net 2019-03-12T23:16:03Z urn:sha1:c984f807703fb113c3e53d9a61d38e1cc83bf196 Make alpha_blend support RGBA as well as BGRA. 2019-03-08T23:23:34Z Carl Hetherington cth@carlh.net 2019-03-08T23:23:34Z urn:sha1:ebc33f0cc5790fe8bd7f921da92c43a11fb0772b Add some comments. 2019-01-31T01:34:56Z Carl Hetherington cth@carlh.net 2019-01-31T01:34:56Z urn:sha1:d31bb9dd64630718fe7faa607e61be7ba88e9097
