BaseAffineTransform(fromsys, tosys, priority=1, register_graph=None)¶
Base class for common functionality between the
This base class is needed because
AffineTransformand the matrix transform classes share the
_apply_transform()method, but have different
StaticMatrixTransformpasses in a matrix stored as a class attribute, and both of the matrix transforms pass in
Nonefor the offset. Hence, user subclasses would likely want to subclass this (rather than
AffineTransform) if they want to provide alternative transformations using this machinery.
