Bug ID: 423959
Summary: The ppi of an image affects the pixel size of vector
objects copied into it and creates artifacts with
layer copying.
Product: krita
Version: nightly build (please specify the git hash!)
Platform: Debian stable
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Layers/Vector
Assignee: krita-bugs-n...@kde.org
Reporter: ahab.greybe...@hotmail.co.uk
Target Milestone: ---
SUMMARY
This happens in all appimages from 4.2.0 to the Jul 06 5.0.0 prealpha (git
193770b)
STEPS TO REPRODUCE
(Image size and ppi values are illustrative.)
1. Create a first new image of 2048 x 2048 pixels at 100 ppi
2. Create a second new image of 2048 x 2048 pixels at 150 ppi
3. Draw a vector shape in the first image, select it and copy it.
4. Paste the copied vector shape into a vector layer in the second image.
NOTE: The pasted vector shape in the second image is 150% of the size of the
shape in the first image.
5. Create a third new image of 2048 x 2048 at 150 ppi
6. In the first image, copy the vector layer and paste it into the third image.
NOTE: An apparently correct size vector object appears.
7. Try to select that vector object.
NOTE: It can't be selected. It's an artifact.
8. Use the MOVE tool to try to move it.
NOTE: A 150% size object appears and moves but the artifact remains. The
bounding box encloses both the artifact and the 150% size vector object.
9. Try to use layer visibility manipulation to remove the artifact.
NOTE: It won't go away.
10. Save, Close and reopen the image.
NOTE: The artifact has gone but is in the preview and merged image of the .kra
file.
11. After repeating Steps 5-8, Move the 150% size (movable) object so that it
wipes over the artifact.
NOTE: The artifact is removed.
OBSERVED RESULT
See Steps To Reproduce
EXPECTED RESULT
The pasted vector shape should be the same size in pixels in both images and be
unaffected by image dpi.
The artifact on layer pasting should not occur.
