What is the bug or the crash?

Layer export in QGIS for rasters has an option for Geospatial PDF which always fails with the error as shown in the attached clip. Screenshot 2024-09-26 pdf

Steps to reproduce the issue

Right click on a Raster layer in QGIS. Select Export >> Save As. Select Geospatial PDF from the pulldown list. Set file output etc. >> Write fail error. >> Cannot write raster. blaa blaa

Additional context

This has been a condition of at least the last 10 releases of QGIS. To my knowledge it has never worked.

@Mikester-Calgary Thank for raising this. I've submitted an "enhancement" in https://github.com/qgis/QGIS/pull/58895 which consists just in removing that choice. There are fundamental reasons why export to PDF through this interface connot be done. It would basically require to create a temporary file in one of the other formats (like TIFF) and then use another mode of the underlying GDAL library to export it to PDF. Hopefully I haven't lost you on those details. That could potentially be done automagically but that requires "a bit" of work In the meantime, you can accomplish what you want by indeed using that dialog to save as a GeoTIFF. And then in the Processing toolbox, use the GDAL "translate (convert format)" tool to convert to PDF. In the most simple situations, you may actually use directly the GDAL "translate (convert format)" tool
