Export Layout as PDF in QGIS3

Question

I am trying to export a specific layout with python in QGIS3. But I am struggling with the QgsLayoutExport class. How do you use it? How can specify which layout should be exported? This is the code I tried but it's not working. The layout in the brackets is the layout I want to export.

QgsLayoutExporter(layout).exportToPdf(filepath)

Answer 1

This a basic example how export to pdf where you can espify the layout.

projectInstance = QgsProject.instance()
layoutmanager = projectInstance.layoutManager()
layout = layoutmanager.layoutByName("test") #Layout name
exporter = QgsLayoutExporter(layout)
exporter.exportToPdf("C://test.pdf", QgsLayoutExporter.PdfExportSettings() )

Answer 2

You will also need to include PdfExportSettings() when using the exportToPdf() method. You can call the default values using QgsLayoutExporter.PdfExportSettings().

So your code could look like:

QgsLayoutExporter(layout).exportToPdf( filepath, QgsLayoutExporter.PdfExportSettings() )
