imagerotate

Description

resource imagerotate ( resource src_im, float angle, int bgd_color )

Rotates the src_im image using a given angle in degrees. bgd_color specifies the color of the uncovered zone after the rotation.

The center of rotation is the center of the image, and the rotated image is scaled down so that the whole rotated image fits in the destination image - the edges are not clipped.
