Bug ID: 488343
Summary: Batch Exporter python plugin does not respect trimming
flag
Classification: Applications
Product: krita
Version: 5.2.2
Platform: Microsoft Windows
OS: Microsoft Windows
Status: REPORTED
Severity: wishlist
Priority: NOR
Component: General
Assignee: krita-bugs-n...@kde.org
Reporter: ongyongxin2020+...@gmail.com
Target Milestone: ---
SUMMARY
When exporting layers using the Batch Exporter, the trimming flag is ignored
when the scaling flag is used with a partially transparent layer.
For example, a transparent layer of size 256x256px has a drawn square of size
64x64px.
Exporting the layer with flags `s=50 t=false` (50% scaling, no trimming)
results in an image of size 32x32px, not 128x128px as expected.
STEPS TO REPRODUCE
1. Go to Settings -> Configure Krita -> Python Plugin Manager and enable Batch
Exporter.
2. Restart Krita.
3. Create a new image of size 256x256px.
4. Create a new transparent paint layer, name it `Layer s=50 t=false p=.`, and
delete the existing Background layer.
5. Draw a sqaure of size 64x64px.
6. Save the image as test.kra.
7. Export the layer by clicking 'All Layers' at the bottom right of the window.
OBSERVED RESULT
The PNG exported in the same directory as test.kra has a much smaller size than
the set scaling.
EXPECTED RESULT
The PNG should be 128x128px in size.
SOFTWARE/OS VERSIONS
Windows: 11 Home (patch 22631.3593)
ADDITIONAL INFORMATION
After importing the original GDQuest Batch Exporter plugin, it seems that this
issue was already fixed upstream in this commit:
https://github.com/GDQuest/krita-batch-exporter/commit/5a46f6426cd22bf23ca94ece39097f3f947aa983
Since the plugin hasn't been updated in-tree since 22 December 2021 and the fix
was committed on 6 March 2022, pulling in changes from upstream would be able
to fix this bug.
