2020-11-25Fix corrupted image when over-cropping black filler frames.Carl Hetherington
FFmpegDecoder can emit small black frames (128x128 pixels) when it wants to fill in a gap. Image::crop_scale_window would do the wrong thing if we then applied a crop of greater than 128 in either direction; though cropped_size is correctly clamped, the crop value itself was not and is used to calculate the input data pointers. This would result in random frames, usually at the end of DCPs, often made up of blurry colour washes.
2020-11-20Move make_black_test into image_test.Carl Hetherington
2020-11-17Fix cropping of subsampled images.Carl Hetherington
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.
2020-11-17Use 64-byte alignment for aligned image memory.Carl Hetherington
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).
2020-11-16Make sure we use limited ("video") range data when exporting.Carl Hetherington
Our export formats all currently use limited range but we weren't making sure data fed to the encoders was limited range. Should fix #1832.
2020-11-16Obey requests to change the video range of RGB content.Carl Hetherington
Video that comes in with RGB pixels will not have its video level ranges changed by libswscale (it only does this for YUV and greyscale). Here we add code to do it ourselves for RGB content coming in via image files (e.g. PNG/DPX etc). Part of #1851.
2020-10-13Fix use of DCPOMATIC_TEST_PRIVATE variable to specify whereCarl Hetherington
test private data is.

2019-11-05Provide some test references.Carl Hetherington
2019-11-04Fix incorrect images when cropping without stretch.Carl Hetherington
Always overallocate images so that Image::crop_scale_window is always safe from over-reading buffers. Relates to #1654 and probably #1653.
2019-11-04Fix out-of-bounds read when cropping JPEG2000 images (#1654).Carl Hetherington
2019-11-04Add a test to expose #1654, on valgrind at least.Carl Hetherington
2019-05-24Basic ability to set video range (JPEG/MPEG) at least for YUV content. May ↵Carl Hetherington
not work for RGB. See #1509.
2019-04-25Fix or remove several broken pixel formats in Image::fade and addCarl Hetherington
unit tests for the remainder. Fixes #1532.

2018-10-12Change MagickImageProxy to FFmpegImageProxy and make it use FFmpegCarl Hetherington
to decode images. Hence remove {Image,Graphics}Magick.

2017-04-19Doxygen tweaks.Carl Hetherington
2016-06-21Revert "Use make_shared<>."Carl Hetherington
Support for this seems to vary wildly across DoM's build targets. Stuff that builds on 16.04 won't build on 14.04, for example. Seems to not be worth the hassle now. This reverts commit 5a5324ed3a381a86dfe0a6e3932c1d58fdcd596f.
