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.
2019-05-24Basic ability to set video range (JPEG/MPEG) at least for YUV content. May ↵Carl Hetherington
not work for RGB. See #1509.
2019-05-21Tweak comment.Carl Hetherington
2019-05-03Fix "cannot handle pixel format 26 during make_transparent()" (part of #1545).Carl Hetherington
2019-04-25Fix or remove several broken pixel formats in Image::fade and addCarl Hetherington
unit tests for the remainder. Fixes #1532.
2019-03-12Fix R/B swap with as_png(); support as_png() for any pixel format.v2.13.129Carl Hetherington
2019-03-08Make alpha_blend support RGBA as well as BGRA.Carl Hetherington
2019-01-31Add some comments.Carl Hetherington
2018-12-12Fix bad rendering of AV_PIX_FMT_PAL8 (palette-ised) images (#1426).v2.13.83Carl Hetherington
2018-10-12Restore Image::as_png using libpng.Carl Hetherington
2018-10-12Change MagickImageProxy to FFmpegImageProxy and make it use FFmpegCarl Hetherington
to decode images. Hence remove {Image,Graphics}Magick.
2018-09-06Quell more valgrind warnings.Carl Hetherington
2018-09-02Play PNG subtitles from DCPs; possibly not in the right scale.Carl Hetherington
2018-07-09Try to fix Centos build.Carl Hetherington
2018-07-08Write image subs to DCPs.Carl Hetherington
2018-03-02Fix corruption of subsampled images that are being placed into blackCarl Hetherington
frames at odd offsets, using the same approach that is used when cropping. Should fix #1227.
2018-02-12Add SWS_ACCURATE_RND to sws flags. Without this, conversions to RGB inCarl Hetherington
crop_scale_window_test leave the 6 pixels at the right side of the image uninitialised (sws_scale doesn't fill them in with anything) so you get garbage in the output. SWS_ACCURATE_RND fixes it. There are whisperings that this is slow, so the impact of this patch may need to be measured in some "real" situations.
2018-01-11Harden alpha blend tests and fix alpha_blend again.Carl Hetherington
2018-01-10Fix yet more pixel order confusions.Carl Hetherington
2018-01-10Fix some incorrect alpha blending; may help with #1155.Carl Hetherington
2018-01-03Fix alpha blending with with offset; should help with #1155.Carl Hetherington
2018-01-03Fix incorrect alpha-blend in some cases.Carl Hetherington
2018-01-03Use convert_pixel_format a little.Carl Hetherington
2018-01-02Add convert_pixel_format convenience function.Carl Hetherington
2017-12-30Add missing factor to fix problems when padding in subsampled containers; ↵Carl Hetherington
should fix #1129.
2017-12-30Make horizontal_factor look the same as vertical_factor.Carl Hetherington
2017-12-29Add basic memory-used stuff for butler and reduce minimum audioCarl Hetherington
readahead quite a bit. This in turn reduces the maximum butler memory usage as it will keep getting audio (and hence video) until the minimum audio readahead is hit.
2017-09-26Speculative fix for alpha blending onto YUV422P10LE.Carl Hetherington
2017-06-07Fix crash when alpha-blending subtitles onto YUV420 images.Carl Hetherington

2017-05-24Better error message.Carl Hetherington
2017-04-19Various Doxygen fixes.Carl Hetherington
2016-08-22Do full gamma correction etc. when alpha-blending subtitlesCarl Hetherington
onto XYZ images. This fixes colour tints on subtitles burnt into existing DCPs.
2016-07-16Remove unused method.Carl Hetherington
2016-07-09Missing swap in Image::swap.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.
2016-06-21Use make_shared<>.Carl Hetherington
2016-06-13Rename MD5Digester -> Digester.Carl Hetherington
2016-05-26Fix slightly inexplicable RGB/BGR confusion; before this the colour of ↵Carl Hetherington
subtitles is wrong.
2016-05-25No-op; fix GPL address and use the explicit-program-name version.Carl Hetherington
2016-05-12Optimise image scaling for the preview.Carl Hetherington
2016-05-11Fix typo (* for +) and use libdcp's sRGB to XYZ matrix (to help with #752).Carl Hetherington
2016-05-04Allow build with the Ubuntu 16.04 version of FFmpeg.Carl Hetherington
2016-03-08Bump ffmpeg to master somewhere post 3.0.Carl Hetherington
2015-11-17Fix crash due to writing off the end of an Image's buffer; see comments.Carl Hetherington
2015-11-08Add appearance dialog for SubRip subtitles.Carl Hetherington
2015-11-03Add missing alpha_blend() for XYZ content so that subtitle overlay works on ↵Carl Hetherington
DCP content again.
2015-10-29Fix incorrect colourspace conversion of XYZ contentCarl Hetherington
when it is not being passed through as untouched JPEG2000 (#730).
