template<class PixelPolicy >

PixelPolicy::pixel_type degate::StoragePolicy_File< PixelPolicy >::get_pixel	(	unsigned int	x,
		unsigned int	y
	)		const [inline, virtual]

Get pixel for "native" pixel types.

This method is abstract. If you derive from this class, you should implement it for a concrete StoragePolicy.

Implements degate::StoragePolicy_Base< PixelPolicy >.
