rotate_xy

Rotate image by an arbitrary angle, around a center point.

Rotate image by an arbitrary angle, around a center point.

rotate_xy(im, angle, cx, cy, interpolation = 1L, boundary_conditions = 0L)

`im`	an image
`angle`	Rotation angle, in degrees.
`cx`	X-coordinate of the rotation center.
`cy`	Y-coordinate of the rotation center.
`interpolation`	Interpolation type. 0=nearest \| 1=linear \| 2=cubic
`boundary_conditions`	Boundary conditions. 0=dirichlet \| 1=neumann \| 2=periodic
