Bug ID: 412624
Summary: Krita 4.2.7.1 Using "Create separate separation from
alpha channel" in the "Separate Image..." semi-hangs
Krita.
Product: krita
Version: 4.2.7
Platform: MS Windows
OS: MS Windows
Status: REPORTED
Severity: critical
Priority: NOR
Component: General
Assignee: krita-bugs-n...@kde.org
Reporter: snopm...@yahoo.com
Target Milestone: ---
SUMMARY
Using "Create separate separation from alpha channel" in the "Separate
Image..." semi-hangs Krita.
STEPS TO REPRODUCE
1. Open the attached file, "Harada.Takehito.full.1043457.jpg" in Krita.
2. Go to "Image" > "Separate Image..."
3. Under "Alpha Options" select the "Create separate separation from alpha
channel."
4. Then select "OK."
OBSERVED RESULT
When I used "Separate Image..." on a JPEG image I found online, and pick
"Create separate separation from alpha channel," nothing seems to happen, but
after this I can't use any brush to draw or erase the canvas. When I try to
close out Krita, there's a message box with a loading bar that says "Waiting
for image operation to complete..." And it's just stuck like that until I close
it out. If I didn't try to draw or erase on the canvas after the "Separate
Image..." operation, it closes out right away. Either case, after I close Krita
and look at the task manager, Krita is still running in the background.
EXPECTED RESULT
The image is split into red, green, blue, and alpha layer channels.
