Synopsis

HxImageRep HxArg(HxImageRep img)

Input

HxImageRep img

The image you want to take the complex argument of.

Return value

HxImageRep

The pixelwise complex argument of the input image.

Description

The function HxArg takes the argument of each pixel value. The input image should be a complex value image, i.e. a vec2 image. The argument is the counterclockwise angle from the positive real axis. When the complex number x+iy is represented by (x,y) then for the argument a holds that The resulting image is scalar.

Remarks

Valid input images

Only vec2 images are valid input images for this function.
