libdcp - DCP handling library

Age	Commit message (Collapse)	Author
2017-01-10	Remove unused code.	Carl Hetherington

2016-12-14	Add tentative S-Gamut3/S-Log3 colourspace support.	Carl Hetherington

2016-12-14	Add function for D65 white point.	Carl Hetherington

2016-08-12	Try non-linearised gamma of 2.4 for Rec 2020.	Carl Hetherington
	Some discussion of this on #892. Also influenced by discussions with Dennis (email Tue, 30 Jun 2015) on how the oft-quoted (e.g. by Wikipedia) gamma functions are camera transforms and not intended for uses like ours. Also see ITU-r BT1886 which talks about a gamma of 2.4.
2016-06-13	Add OpenSSL licence exception.	Carl Hetherington

2016-06-01	Still more licence fixups.	Carl Hetherington

2016-05-25	No-op; Fix GPL address and mention libdcp by name.	Carl Hetherington

2016-05-24	Add somewhat speculative Rec 1886 and Rec 2020 colour conversions.	Carl Hetherington

2015-06-29	Return to DCP-o-matic v1's gamma correction for Rec 601/709.	Carl Hetherington
	Dennis points out that `there definitely is no right answer for BT.709 gamma' and `your formula [the DCP-o-matic v2 gamma function before this commmit] is what I'm calling the inverse of the BT.709 camera transfer function. The EBU would not have bothered to write: "Therefore the monitor gamma is not, and never has been, the inverse of the camera gamma." if no-one ever thought of using it'. At least the 2.2 gamma of v1 should not surprise anybody.
2015-06-24	No-op: whitespace.	Carl Hetherington

2015-04-22	Add p3_to_xyz colour conversion preset.	Carl Hetherington

2015-04-22	Fix crash in previous.	Carl Hetherington

2015-04-22	Express colour conversions as chromaticities and adjust so that	Carl Hetherington
	everything is specified as something_to_xyz and then you can get an inverse LUT if you want one.
2015-02-17	Use 2.222222 for the power in the modified Rec. 709 input gamma	Carl Hetherington
	correction, as per fnordware DCIconverter.
2015-02-17	Rec 709 -> XYZ and sRGB -> XYZ matrices are, it seems, the same;	Carl Hetherington
	I'm getting this from fnordware DCIconverter. https://github.com/fnordware/DCIconverter/blob/master/src/DCIconverter.cpp
2015-02-17	Typo causing wrong matrix to be used for Rec. 709.	Carl Hetherington

2015-01-04	Try to fix static initialisation order problems.	Carl Hetherington

2015-01-03	Various fixes to XYZ/RGB transforms.	Carl Hetherington

2014-12-28	Change colourspace handling round a bit:1.0-colour-cleanup	Carl Hetherington
	- move the essence of GammaLUT into TransferFunction and handle different bit depths more neatly - add ColourConversion to describe input gamma correction, colour transformation and then output gamma correction in one class. - add default ColourConversions for sRGB->XYZ, Rec709->XYZ and XYZ->RGB.
