Bug ID: 404615
Summary: Dimensions of Images output by "Export Layers" vary
wildly depending on the layers alpha
Product: krita
Version: 4.1.7
Platform: MS Windows
OS: MS Windows
Status: REPORTED
Severity: normal
Priority: NOR
Component: Scripting
Assignee: krita-bugs-n...@kde.org

Created attachment 118230

this has three layers, each layer will have high variation in dimensions when
exported via the Export-Layers script.
SUMMARY
scripts->"Export Layers" downsizes the exported image dimensions, depending on
the alpha values of the layer. This is most apparent when the layer has fully
transparent pixels around the border of the image.
STEPS TO REPRODUCE
1. Create a 1024x1024 px krita document.
2. Clear all the layers so that you have a completely transparent document.
3. Paint a small (for example, 2 pixel by 2 pixel) black dot in the center of
the image.
3. Run the export layers command (from Tools->Scripts->"Export Layers") on the
recently created document/layer.
4. inspect the images that were output by the 'Export Layers' script.
OBSERVED RESULT
The output images are down-sized depending on the layer's alpha. So, if you
only have a 2px-by-2px dot in the layer, the output image size is 2px by 2px.
EXPECTED RESULT
We'd expect the dimensions of the output image to have the same dimensions as
the images in the document (1024x1024, in the case of the repro steps). That's
the way that 'File->Export' works.
If the downsizing is a 'feature', we'd expect the feature to be configurable
via the "Export Layers" dialog box (it currently isn't).
