Detailed Description

Function Documentation

HxImageRep L_HXIMAGEREP HxOrVal (  HxImageRep    im,
HxValue    val
) 
 

Or.

The function performs or (see Pixels) on all pixels in the input image via a binary pixel operation (see Images).

Implementation specifics : The pixel functor : HxBpoOr. The image functor instantiator : HxInstantiatorOrV.
