Add CAM02 JCh and CAM02-UCS J'a'b' conversions

2017-09-30T12:00:53+00:00

* 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

2017-09-22T03:06:00+00:00

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.

Fix 2 testsuite tests for MS-Windows

2017-09-20T07:16:11+00:00

* test/lisp/ibuffer-tests.el (test-buffer-list): Don't try to
create files with "*" in their names.
* test/src/editfns-tests.el (format-time-string-with-zone): Adapt
results to MS-Windows build.  Reported by Fabrice Popineau
.

Adapt fileio-tests--symlink-failure to Cygwin

2017-09-18T21:22:52+00:00

* test/src/fileio-tests.el (fileio-tests--symlink-failure)
[CYGWIN]: Skip the case of a symlink target starting with '\';
this is treated specially on Cygwin.

Fix format-time-string %Z bug with negative tz

2017-09-18T03:39:12+00:00

* src/editfns.c (tzlookup): Fix sign error in %Z when a purely
numeric zone is negative (Bug#28746).
* test/src/editfns-tests.el (format-time-string-with-zone):
Add test for this bug.

Fix bug with min and max and NaNs

2017-09-17T22:26:41+00:00

* src/data.c (minmax_driver): Fix bug with (min 0 NaN), which
mistakenly yielded 0.  Also, pacify GCC in a better way.
* test/src/data-tests.el (data-tests-min): Test for the bug.

* test/src/lcms-tests.el (lcms-cri-cam02-ucs): Skip if lcms2 not present.

2017-09-16T20:56:56+00:00

* test/src/lcms-tests.el (lcms-whitepoint): Skip if lcms2 not present.

2017-09-16T20:56:56+00:00

(cherry picked from commit 8081df26911c63aadfce4ee8f6a7223d814baeaf)

Add lisp variable lcms-d65-xyz

2017-09-16T16:49:28+00:00

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

2017-09-16T03:49:42+00:00

* src/lcms.c (lcms-temp->white-point): New function.
* test/src/lcms-tests.el: New file.
