Detailed Description

Function Documentation

HxImageRep L_HXIMAGEREP HxArg (  HxImageRep    im ) 
 

Argument.

The function computes the complex argument (see Pixels) of all pixels in the input image via a unary pixel operation (see Images).

Implementation specifics : The pixel functor : HxUpoArg. The image functor instantiator : HxInstantiatorArg.
