tan_image — Calculate the tangent of an image.
tan_image calculates the tangent of an input image Image and stores the result in the image TanImage of type real. If Image is of type direction or cyclic, the angles in Image are converted to radians internally. If Image is of type real, the angles in Image are assumed to be represented in radians. For direction images, the value of 255 will result in a value of 0 in the output image.
tan_image can be executed on OpenCL devices.
