atan2_image — Calculate the arctangent of two images.
atan2_image calculates the arctangent
ImageX of the input images
ImageX, using the signs of the gray
values of the two images to determine the quadrant of the result,
and stores the result in the image
ArctanImage. The angles
ArctanImage are represented in radians.
atan2_image can be executed on an OpenCL device for int1,
int2, int4, and real images. Note that the results of the OpenCL
code may vary from the results produced by the CPU.

Input image 1.
→object (int1 / int2 / int4 / int8 / real)
Input image 2.
