Class: QgsVectorWarper¶

Vector layer warper which warps vector layers based on a list of source and destination GCPs.

Added in version 3.26.

Methods

`error`	Returns the last error obtained during transformation.
`transformFeatures`	Transforms the features from iterator and adds the results to the specified sink.

class qgis.analysis.QgsVectorWarper[source]¶

Bases: object

Constructor for QgsVectorWarper.

Parameters:

method (QgsGcpTransformerInterface.TransformMethod) – specifies the transformation method
points (Iterable[QgsGcpPoint]) – list of GCP points to use for the transformation
destinationCrs (QgsCoordinateReferenceSystem) – target CRS for transformed features

__init__(a0: QgsVectorWarper)

error(self) → str[source]¶

Returns the last error obtained during transformation.

transformFeatures(self, iterator: QgsFeatureIterator, sink: QgsFeatureSink | None, context: QgsCoordinateTransformContext, feedback: QgsFeedback | None = None) → bool[source]¶

Transforms the features from iterator and adds the results to the specified sink.

The optional feedback argument can be used for progress reporting and cancellation.

Return type:

bool

Returns:

True if all features were successfully transformed

Parameters:
