Bug ID: 356303
Summary: Overlay blend mode appears incorrect in a 16 bit image
Product: krita
Version: 2.9.9
Platform: MS Windows
OS: MS Windows
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: Color models
Assignee: krita-bugs-n...@kde.org
Reporter: cjo...@chrisj.com.au
The opacity of a layer or brush set to Overlay blend mode in a 16 bit image
produces a lower level of opacity than the same layer in an 8 bit image.
Reproducible: Always
Steps to Reproduce:
1. Create a new 16 bit image
2. Paint some grey on Layer 1
3. Set Layer 2 to Overlay and paint over the grey with white. Note that the
strokes are grey rather than white
4. Convert the image to 8 bit and see the strokes on Layer 2 turn to opaque
white
Photoshop does not exhibit this behaviour - it displays the white as opaque
white regardless of the colour depth. Saving the 16 bit image from Krita as a
.psd and reducing the colour depth to 8 bit in Photoshop retains Layer 2's
original grey appearance however.
