How to rotate/translate/flip vtkActor2D object using vtk?

Question

I have a vtkActor2D object that I wish to rotate/translate/flip. Is there a simple way to rotate/translate/flip about its center?

Answer 1

对于vtkActor2D，请使用SetPoint(float, float)（左下角）和SetPoint2(float, float)（右上角）来控制位置。请注意，这也允许您旋转道具，但您必须自己进行数学运算，或者使用 Actor2D给你的vtkCoordinate。
