Setting options in "PDF Export Options" to export an atlas to PDF using PyQGIS

Question

While saving an atlas as PDF in QGIS, I can manually change the settings shown the image using "PDF Export Settings" window.

How can I set those options using PyQGIS?

Minimal code:

layout_manager = QgsProject.instance().layoutManager()
layout = layout_manager.layoutByName('LAYOUT_NAME')

layout_exporter = QgsLayoutExporter(layout)    
layout_exporter.exportToPdf(path, QgsLayoutExporter.PdfExportSettings())

Answer 1

Setting those options using PyQGIS requires using QgsLayoutExporter.PdfExportSettings() instance.

pdf_settings = QgsLayoutExporter.PdfExportSettings()

Then;

1. For "Always export as vector"
   pdf_settings.forceVectorOutput = True or False.

2. For "Export RDF metadata"
   pdf_settings.exportMetadata = True or False.

3. "Text export" options:

   • For "Always Export Text as Paths"
     pdf_settings.textRenderFormat = QgsRenderContext.TextFormatAlwaysOutlines

   • For "Always Export Text as Text Objects"
     pdf_settings.textRenderFormat = QgsRenderContext.TextFormatAlwaysText

4. For "Disable tiled raster layer exports"
   pdf_settings.rasterizeWholeImage = True or False.

layout_manager = QgsProject.instance().layoutManager()
layout = layout_manager.layoutByName('LAYOUT_NAME')

pdf_settings = QgsLayoutExporter.PdfExportSettings()

pdf_settings.forceVectorOutput = True` # default False
pdf_settings.exportMetadata = False # default True
pdf_settings.rasterizeWholeImage = True # default False
pdf_settings.textRenderFormat = QgsRenderContext.TextFormatAlwaysText
# OR pdf_settings.textRenderFormat = QgsRenderContext.TextFormatAlwaysOutlines # default

layout_exporter = QgsLayoutExporter(layout)    
layout_exporter.exportToPdf(path, pdf_settings)
