Function Documentation

template<class T>

vil1_image vil1_image_as	(	vil1_image const &	i,
		T *	dummy
	)

Converts to a different pixel type.

There is no scaling performed, so beware of clamping effects. Sample usage:

   out = vil1_image_as<int>( in );

or, on compilers that require the arguments to specify the templates:

   out = vil1_image_as( in , (int*)0 );

Converting a RGB buffer to greyscale will do a RGB->luminance conversion. That is, different weights will be applied to each of the R, G and B values to obtain the resulting grey value.
