An interface for Ground Control Points (GCP) based transformations.
|
|
|
|
:py:class:`QgsGcpTransformerInterface` implementations are able to
|
|
transform point locations based on a transformation method and a list of
|
|
GCPs.

Clones the transformer, returning a new copy of the transformer with the

|
Fits transformation parameters using the specified Ground Control Points
|
|
(GCPs) lists of source and destination coordinates.
|
|
|
|
If ``invertYAxis`` is set to ``True`` then the y-axis of source
|

coordinates will be inverted, e.g. to allow for transformation of raster

layers with ascending top-to-bottom vertical axis coordinates.

|

Transforms the point (``x``, ``y``) from source to destination
|
|
coordinates.

If ``inverseTransform`` is set to ``True``, the point will be
|
|
transformed from the destination to the source.

Creates a new QgsGcpTransformerInterface subclass representing the

specified transform ``method``, initialized using the given lists of

source and destination coordinates.

If the parameters cannot be fit to a transform ``None`` will be

returned.

Caller takes ownership of the returned object.
