Detailed Description

Handles geospatial PDF export specific setup, cleanup and processing steps.

This class is a low level implementation detail only. Generally, you should use the high level interface exposed by QgsLayoutExporter instead.

Warning

QgsLayoutGeospatialPdfExporter is designed to be a short lived object. It should be created for a single layout export operation only, and then immediately destroyed. Failure to correctly destroy the object after exporting a layout will leave the layout in an inconsistent, unstable state.

Member Function Documentation

customLayerTreeGroups()

QMap< QString, QString > QgsLayoutGeospatialPdfExporter::customLayerTreeGroups ( ) const

inline

Returns any custom layer tree groups defined in the layer's settings.

layerTreeGroupOrder()

Definition at line 63 of file qgslayoutgeopdfexporter.h.

initialLayerVisibility()

QMap< QString, bool > QgsLayoutGeospatialPdfExporter::initialLayerVisibility ( ) const

inline

Optional map of map layer ID to initial visibility state.

If a layer ID is not present in this, it will default to being initially visible when opening the PDF.

Since

QGIS 3.14

Definition at line 71 of file qgslayoutgeopdfexporter.h.

layerOrder()

QStringList QgsLayoutGeospatialPdfExporter::layerOrder ( ) const

inline

Optional list of map layer IDs in the order they should be shown in the generated geospatial PDF layer tree.

Layer IDs earlier in the list will appear higher in the geospatial PDF layer tree.

Since

QGIS 3.14

Definition at line 80 of file qgslayoutgeopdfexporter.h.

layerTreeGroupOrder()

QStringList QgsLayoutGeospatialPdfExporter::layerTreeGroupOrder ( ) const

inline

Specifies the ordering of layer tree groups in the generated geospatial PDF file.

Groups appearing earlier in the list will show earlier in the geospatial PDF layer tree list.
