class QgsGcpTransformerInterface /Abstract/

%Docstring(signature="appended")
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
same parameters as this one.
Caller takes ownership of the returned object.

%Docstring
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.
:return: ``True`` on success, ``False`` on failure
%End

Returns the minimum number of Ground Control Points (GCPs) required for
parameter fitting.

%Docstring
Returns the transformation method.
%End
bool transform( double &x /In,Out/, double &y /In,Out/, bool inverseTransform = false ) const;
%Docstring
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.
:return: ``True`` if transformation was successful.
%End

%Docstring
Returns a translated string representing the specified transform
``method``.
%End

Creates a new QgsGcpTransformerInterface subclass representing the
specified transform ``method``.
Caller takes ownership of the returned object.
%End

%Docstring
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.
