Bug ID: 410308
Summary: Possible to un-‘grey out’ option for downscaling to
8-bit for 8-bit images when separating colour channels
Product: krita
Version: git master
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: General
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
When you try to separate the colour channels of an 8-bit image, the ‘Downscale
to 8-bit before separating’ option is greyed out. This makes sense, since the
image channels are already 8-bit channels. But by changing the ‘Output to
color, not grayscale’ option *twice*, it’s possible to reenable the ‘Downscale
to 8-bit before separating’ option. This should not be possible.
STEPS TO REPRODUCE
1. Create a new 8-bit document.
2. Select ‘Image → Separate Image’.
3. Select ‘Output to color, not grayscale’.
4. Deselect ‘Output to color, not grayscale’.
OBSERVED RESULT
‘Downscale to 8-bit before separating’ is no longer greyed out, and it is
possible to enable the option.
EXPECTED RESULT
‘Downscale to 8-bit before separating’ should always be greyed out (and
unselectable), since the image is already an 8-bit image.
