rotate

Built-in command

Arguments:

• angle,_interpolation,_boundary_conditions,_center_x[%],_center_y[%]    or
• u,v,w,angle,interpolation,boundary_conditions,_center_x[%],_center_y[%],_center_z[%]

Description:

Rotate selected images with specified angle (in deg.), and optionally 3D axis (u,v,w).

interpolation can be { 0:None | 1:Linear | 2:Bicubic }.
boundary_conditions can be { 0:Dirichlet | 1:Neumann | 2:Periodic | 3:Mirror }.
When a rotation center (cx,cy,_cz) is specified, the size of the image is preserved.

Default values:

interpolation=1, boundary_conditions=0 and center_x=center_y=(undefined).
