Bug ID: 459117
Summary: Linear gamma ICC profiles return an "Undefined"
transfer characteristic
Product: krita
Version: git master (please specify the git hash!)
Platform: Compiled Sources
OS: Microsoft Windows
Status: REPORTED
Severity: normal
Priority: NOR
Component: Color models
Assignee: krita-bugs-n...@kde.org

SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug
symbols.
See
https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***
Linear gamma ICC profiles, such as Elle's Rec.2020 profile, return
TRC_UNDEFINED when KoColorProfile::getTransferCharacteristics() is called. This
is incorrect, as KoColorProfile::isLinear() will happily say yes and
getEstimatedTRC() will also return (1, 1, 1).
STEPS TO REPRODUCE
1. Instantiate a copy of the following profile:
`KoColorSpaceRegistry::instance()->profileFor({},
PRIMARIES_ITU_R_BT_2020_2_AND_2100_0, TRC_LINEAR);`
2. Query getTransferCharacteristics().
OBSERVED RESULT
It returns TRC_UNDEFINED.
EXPECTED RESULT
It returns TRC_LINEAR.
