Vectorization of selective masking when exporting as GeoPDF #54852

Open cxcandid opened 1 year ago

cxcandid commented 1 year ago

Feature description

In QGIS 3.26 we got this great enhancement (https://github.com/qgis/QGIS-Enhancement-Proposals/issues/186) of selective masking vectorization for PDF and SVG exports (https://www.qgis.org/en/site/forusers/visualchangelog326/#feature-selective-masking-vectorization, ). Unfortunately it doesn't work in PDF, when Create Geospatial PDF (GeoPDF) is enabled.

Is there any chance to get this feature even for GeoPDF exports?

Additional context

@troopa81, may you please have a look at this?

troopa81 commented 1 year ago

It's not an easy fix because the code used to render a GeoPDF is specific (QGIS need to generate one layer at a time) and is not aware of the 2-pass rendering needed for selective masking (render mask first then masked).

If you willing to fund such a feature, you can contact me at julien dot cabieces at oslandia dot com

At the moment I use a special workaround to get around this issue: https://gis.stackexchange.com/questions/52858/interrupting-contour-lines-beneath-elevation-labels-instead-of-using-label-buff/343274#343274
