vil1_image vil1_clamp	(	vil1_image	src,
		double	range_min,
		double	range_max
	)

Adaptor which returns a vil1_image with pixel components clamped to given range.

Fits nicely into the functional composition and lazy evaluation scheme provided by the other vil1 adaptors. Old code can be implemented in the new style as vil1_image_as_byte(vil1_clamp(img, 0, 255)); vil1_image_as_rgb_byte(vil1_clamp(img, 0, 255));

template<class V>

V vil1_clamp_pixel	(	V const &	b,
		double	range_min,
		double	range_max
	)			[inline]

Convenience templated functions for clamping of a single pixel.

(vxl_byte)vil1_clamp_pixel(g, 0, 255); (vil1_rgb<vxl_byte>)vil1_clamp_pixel(rgb, 0, 255);
