Arguments:
- "expr_radius",_"expr_angle",_center_x[%],_center_y[%],_boundary_conditions={ 0:Dirichlet | 1:Neumann | 2:Periodic | 3:Mirror }
Description:
Apply user-defined transform on polar representation of selected images.Default values:
expr_radius=R-r, expr_rangle=a, center_x=center_y=50% and boundary_conditions=3.
Example of use:
