exportRasterBlock

Exports mesh layer’s dataset values as raster block

Signals

Attributes

exportRasterBlock(layer: QgsMeshLayer, datasetIndex: QgsMeshDatasetIndex, destinationCrs: QgsCoordinateReferenceSystem, transformContext: QgsCoordinateTransformContext, mapUnitsPerPixel: float, extent: QgsRectangle, feedback: QgsRasterBlockFeedback = None) → QgsRasterBlock

Exports mesh layer’s dataset values as raster block

The function always fetches native mesh and dataset data from data provider and calculates triangular mesh

Parameters

  • layer – mesh layer

  • datasetIndex – index from layer defining group and dataset (time) to export

  • destinationCrs – destination/map CRS. Used to create triangular mesh from native mesh

  • transformContext – Transform context to transform layer CRS to destination CRS

  • mapUnitsPerPixel – map units per pixel for block

  • extent – extent of block in destination CRS

  • feedback – optional raster feedback object for cancellation/preview

Returns

raster block with Float.64 values. None on error

New in version 3.6.
