abstract class for representing affine transformation widgets
virtual void GetTransform(vtkTransform *t)=0
Retrieve a linear transform characterizing the affine transformation generated by this widget.
void PrintSelf(ostream &os, vtkIndent indent) override
Standard methods for instances of this class.
void ShallowCopy(vtkProp *prop) override
Methods to make this class properly act like a vtkWidgetRepresentation.
~vtkAffineRepresentation() override
