Cannot export project to georeferenced pdf when view is rotated

wanderingnature commented 1 year ago

What is the bug or the crash?

Project -> Import/Export -> Export Map to PDF does not work when the view is rotated

I have tested various projects and find consistent behavior unrelated to whether vector or raster layers are to be exported, scale of map, resolution of map, etc...

If I have the Map View as not rotated, e.g. 0° then export as georeferenced PDF works as expected. If the map view is rotated even 1° then the export fails.

This is not documented behavior and thus I would consider it a bug - or change the documentation to reflect this limitation. I do not have other versions to test on - I am on 3.28.2 / Mac Mojave 10.14.6

Steps to reproduce the issue

Any vector or raster layer in map view window rotate the view an amount, I tested 1°, 15°, 90° Project -> Import/Export -> Export Map regardless of scale, resolution, or other settings - check Create Geospatial PDF (GeoPDF)

RESULT: Save as PDF: Could not save the map to PDF error

Rotate the map view to 0° regardless of scale, resolution, or other settings - check Create Geospatial PDF (GeoPDF) RESULT: map saves correctly

Documentation used: https://docs.qgis.org/3.22/en/docs/user_manual/introduction/qgis_gui.html#exportingmapcanvas There is no mention of any limitation regarding rotation of the map view.

The issue also occurs on Windows using QGIS 3.28.2 (and previous version like 3.22 / 3.16 / 3.10) if:

the map rotation is not 0° AND
the "Create Geospatial PDF (GeoPDF)" option is checked AND
the "Append georeference information (embedded or via world file)" option is checked

@wanderingnature thanks for reporting.

For a Print Layout, the export as a Geospatial PDF is disabled if one or more map items are rotated. So it should be disabled also in the map canvas export dialog.

I think this issue could be fixed in a similar way as in layout with https://github.com/qgis/QGIS/commit/834204fd94fdf40d042c9151d36fea739542d2c3 (https://github.com/qgis/QGIS/pull/36989) by @nyalldawson.
