*	Update copyright year to 2018	Paul Eggert	2018-01-01	1	-1/+1
\| \| \| \|	Run admin/update-copyright.
*	Add CAM02 JCh and CAM02-UCS J'a'b' conversions	Mark Oteiza	2017-09-30	1	-0/+44
\| \| \| \| \| \| \| \| \| \| \| \|	* src/lcms.c (rad2deg, parse_jch_list, parse_jab_list, xyz_to_jch): (jch_to_xyz, jch_to_jab, jab_to_jch): New functions. (lcms-jch->xyz, lcms-jch->xyz, lcms-jch->jab, lcms-jab->jch): New Lisp functions. (lcms-cam02-ucs): Refactor. (syms_of_lcms2): Declare new functions. * test/src/lcms-tests.el (lcms-roundtrip, lcms-ciecam02-gold): (lcms-jmh->cam02-ucs-silver): New tests. * etc/NEWS: Mention new functions.
*	Expose viewing conditions in CAM02-UCS metric	Mark Oteiza	2017-09-21	1	-5/+32
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Also add tests from the colorspacious library. Finally, catch an errant calculation, where degrees were not being converted to radians. * src/lcms.c (deg2rad, default_viewing_conditions): (parse_viewing_conditions): New functions. (lcms-cam02-ucs): Add comments pointing to references used. Expand the docstring and explain viewing conditions. JCh hue is given in degrees and needs to be converted to radians. (lcms-d65-xyz): Remove. No need to duplicate this in Lisp or make the API needlessly impure. * test/src/lcms-tests.el: Reword commentary. (lcms-rgb255->xyz): New function. (lcms-cri-cam02-ucs): Fix let-binding. (lcms-dE-cam02-ucs-silver): New test, assimilated from colorspacious.
*	* test/src/lcms-tests.el (lcms-cri-cam02-ucs): Skip if lcms2 not present.	Glenn Morris	2017-09-16	1	-0/+1

*	* test/src/lcms-tests.el (lcms-whitepoint): Skip if lcms2 not present.	Glenn Morris	2017-09-16	1	-1/+2
\| \| \| \|	(cherry picked from commit 8081df26911c63aadfce4ee8f6a7223d814baeaf)
*	Add lisp variable lcms-d65-xyz	Mark Oteiza	2017-09-16	1	-0/+19
\| \| \| \| \| \| \| \| \| \|	This serves as the default optional argument for functions in this library. * src/lcms.c (lcms-d65-xyz): New variable. (lcms-cam02-ucs): Use it. Use better word in docstring. Fix bug color1 -> color2. * test/src/lcms-tests.el: Add some tests for lcms-cri-cam02-ucs. (lcms-colorspacious-d65): New variable.
*	Add lcms-temp->white-point and initial tests	Mark Oteiza	2017-09-15	1	-0/+69
	* src/lcms.c (lcms-temp->white-point): New function. * test/src/lcms-tests.el: New file.
