Colour 0.4.5 - Alpha Milestone

Features

Environment (#1239, @KelSolaar)

It is now possible to create a ~/.colour-science/colour-science.jenv JSON file from which Colour will load environment variables from:

{
  "COLOUR_SCIENCE__COLOUR__SHOW_WARNINGS_WITH_TRACEBACK": 1
}

The following new environment variables are now supported:

• COLOUR_SCIENCE__FILTER_RUNTIME_WARNINGS: Filter Colour runtime warnings.
• COLOUR_SCIENCE__FILTER_USAGE_WARNINGS: Filter Colour usage warnings.
• COLOUR_SCIENCE__FILTER_COLOUR_WARNINGS: Filter Colour warnings, this also filters Colour usage and runtime warnings.
• COLOUR_SCIENCE__FILTER_PYTHON_WARNINGS: Filter Python warnings.

Input and Output

• The definitions reading from and writing to files now support the pathlib.Path type. (#ff4fe99337cc3ba0e4d1b9071bc22afb4db3c7f5, @KelSolaar)

colour.characterisation

• Add the ColorChecker SG chromaticity coordinates with the colour.CCS_COLOURCHECKERS["ColorCheckerSG - Before November 2014"] and colour.CCS_COLOURCHECKERS["ColorCheckerSG - After November 2014"] attribute keys.

colour.colorimetry

• PR: Use shape if passed, to also reshape the colour.continuous.AbstractContinuousSignal sub-classes in colour.colorimetry.sd_to_XYZ_integration definition. (#1250, @KelSolaar)

Fixes

colour.colorimetry

• Fix issue where colour.colorimetry.sds_and_msds_to_msds definition did not always copy the converted spectral distributions and was causing seemingly random unit tests failure. (#891d364f1dd167d8ed0be0cc0c9bc10bd06281b2, @KelSolaar)

colour.models

• Change Canon Cinema Gamut whitepoint to D55. (#c25934eabc39152b0182daca063561ed218a4068, @MrLixm, @KelSolaar)

colour.utilities

• Ensure that caches are systematically cleared when changing dtype: It was causing seemingly random unit tests failure. (#8faeb095dc0706f21ffe5adaf1861010b3771e71, @KelSolaar)

    usage_warning(
        'The "ALEXA Wide Gamut" RGB colourspace has been renamed to '
        '"ARRI Wide Gamut 3" for consistency with "ARRI" new naming '

    return RGB_COLOURSPACE_ARRI_WIDE_GAMUT_3

What were you trying to do there with the "ARRI" in quotes like that (fourth-from-last world in warning)? If it's the business entity that you meant, then it would be "ARRI's", i.e. the possessive, without the surrounding double-quotes. Or was it something else you meant?
