C++ (Cpp) gray_color_t Examples

Example #1

File: bmp_io_private.hpp Project: apakian/rtmp-cpp

	/// Split gray to RGBA components
	static void split(const pixel_t& p, channel_t& r, channel_t& g, channel_t& b, channel_t& a) throw() {
		r = get_color(p,gray_color_t());
		g = get_color(p,gray_color_t());
		b = get_color(p,gray_color_t());
		a = ~0;

	}

Example #2

File: gray_alpha.hpp Project: Achammem/TuttleOFX

 void operator()(const P1& src, P2& dst) const {
     get_color(dst,red_t())  =
         channel_convert<typename color_element_type<P2, red_t>::type>(
             channel_multiply(get_color(src,gray_color_t()),get_color(src,alpha_t()) ) 
             );

             channel_multiply(get_color(src,gray_color_t()),get_color(src,alpha_t()) )
