Functions
WlzObject *	WlzRGBAModGradient (WlzObject obj, double width, WlzErrorNum dstErr)
	Calculate the modulus of the rgb-level gradient at each point. The gradient images are calculated using WlzGauss2() with width parameter set to `width`. Note the modulus returned is the modulus of vector formed by the independent channels, i.e. take the modulus for each channel seperately then the modulus of the resultant vector. More...
