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

Description

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

Usage

Arguments

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
