Requires a PDF4Qt enabled build. This method exports the QWebEnginePage
to a PDF file, so that we get nicely vectorised objects and
text-as-text. It's the ONLY supported way in Qt API to do this, every
other method of rendering QWebEnginePage forces rasterisation of
the content.
We then use the QgsPdfRenderer class to render the temporary PDF
content to a QPainter device, which keeps vector objects as vectors.
The original workaround was only supposed to apply to QList/
QVector of QVariantMaps. By replacing them all in sip we
break mapping of signals defined in c++ which are emitted
by Python code.
Fixes exceptions after running processing algorithms in Qt6
builds.
Allows extraction of matching parts from a collection, returning
the corresponding collection subclass.
mixed_collection = QgsGeometryCollection()
mixed_collection.addGeometry(... mix of geometry types ...)
multi_line_string = mixed_collection.extractPartsByType(Qgis.WkbType.LineString)
In this case multi_line_string will be a QgsMultiLineString object,
containing just the line string parts from mixed_collection
And transparently map requests for grass7 provider to grass provider
It's misleading putting an old version number in the provider name,
when this provider supports grass versions 8 +
Use the safer method of explicitly including the provider type
when storing layer sources to string in more places, which eg
fixes running the copied qgis_process string when a non gdal
layer source is used for a raster layer. Also fixes the same
situation when restoring an algorithm from the history log.
Fixes#54264
Instead of writing errors to QgsMessageLog and discarding, instead
make the QgsTessellator class store errors and make the callers
responsible for pushing to QgsMessageLog when appropriate.
Gives us more flexibility to show user facing tesselation errors,
eg in the processing log.
The old sip based approach to handling property -> getter/setter
conversion is broken on sip6, so move the patching into Python.
Also fix incorrect checks in tests, and add additional test
for compatiblity code.
And make sipify handle this nicely. This means that all our non-flag
style enums correctly map across to IntFlag python enums on Qt 6,
fixing issues with negative enum values for these and providing
a better match for the original c++ enum.
