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.
