Use a master .qgz with a layout containing one map item. Then:
Whether you are an engineer automating daily map reports, a researcher building a multi-page atlas, or a consultant merging 50 district maps into a single PDF book, the tools are all there in PyQGIS 3. The official programmer’s guide (in its living online form) provides the theory; the code examples in this article provide the practice. pyqgis programmer 39s guide 3 pdf work
result = exporter.exportToPdf("C:/GIS/output.pdf", settings) if result == QgsLayoutExporter.Success: print("PDF exported successfully") else: print(f"Export failed: result") One of the most powerful uses of PyQGIS PDF workflows is creating atlas-style map books without the QGIS GUI. The QgsLayoutExporter can iterate over features. Use a master
If you have been searching for the definitive "PyQGIS Programmer’s Guide 3 PDF work" , you are likely looking for one of two things: either a downloadable PDF reference for mastering PyQGIS 3, or a workflow to programmatically generate, manipulate, or export PDF documents using the QGIS 3 API. result = exporter
district_layer = QgsProject.instance().mapLayersByName("districts")[0] for feature in district_layer.getFeatures(): # Set map extent to feature geometry map_item.zoomToExtent(feature.geometry().boundingBox()) # Update a text label with district name title_label.setText(f"District feature['name']") # Refresh layout layout.refresh() exporter.exportToPdf(f"feature['name'].pdf", settings) Scenario: You need a PDF where clicking a feature on a legend or table opens a bookmarked page.
# Assuming layout has a coverage layer set layout = project.layoutManager().layoutByName("AtlasLayout") exporter = QgsLayoutExporter(layout) atlas_layout = layout.atlas() atlas_layout.setEnabled(True) atlas_layout.setCoverageLayer(atlas_layer) # polygon grid, e.g., 100 map sheets Export each feature as a separate PDF page or file for i in range(atlas_layout.count()): atlas_layout.setCurrentFeature(i) # Option 1: Single multi-page PDF exporter.exportToPdf(f"C:/GIS/atlas_page_i.pdf", QgsLayoutExporter.PdfExportSettings()) Merging PDFs with PyQGIS QGIS itself does not merge PDFs, but your PyQGIS script can leverage Python’s PyPDF2 or pypdf library after export:
Introduction Quantum GIS (QGIS) has evolved from a simple open-source desktop application into a full-fledged geospatial ecosystem. At its heart lies PyQGIS —the Python binding that allows you to automate, extend, and customize every aspect of the software. For developers and GIS analysts, the transition from QGIS 2.x to 3.x brought a seismic shift in API design, performance, and capability.
