Class: QgsRasterFileWriterTask¶

class qgis.core.QgsRasterFileWriterTask(writer: QgsRasterFileWriter, pipe: QgsRasterPipe, columns: int, rows: int, outputExtent: QgsRectangle, crs: QgsCoordinateReferenceSystem)¶

Bases: qgis._core.QgsTask

Constructor for QgsRasterFileWriterTask. Takes a source writer, columns, rows, outputExtent and destination crs. Ownership of the pipe is transferred to the writer task, and will be deleted when the task completes.

Deprecated since version since: QGIS 3.8, use version with transformContext instead

QgsRasterFileWriterTask(writer: QgsRasterFileWriter, pipe: QgsRasterPipe, columns: int, rows: int, outputExtent: QgsRectangle, crs: QgsCoordinateReferenceSystem, transformContext: QgsCoordinateTransformContext) Constructor for QgsRasterFileWriterTask. Takes a source writer, columns, rows, outputExtent, destination crs and coordinate transformContext . Ownership of the pipe is transferred to the writer task, and will be deleted when the task completes.

QgsTask task which performs a QgsRasterFileWriter layer saving operation as a background task. This can be used to save a raster layer out to a file without blocking the QGIS interface.
