RGB (View)

Include <mln/core/image/view/rgb.hpp>

1. auto red(Image ima)
   

2. auto green(Image ima)
   

3. auto blue(Image ima)
   

   1. Makes a view that project the red channel of an rgb colored image.

   2. Makes a view that project the green channel of an rgb colored image.

   3. Makes a view that project the blue channel of an rgb colored image.

   Parameters:

   ima – Input range

   mln::image2d<mln::rgb8> ima = ...;
   auto ima_r = mln::view::red(ima);
   auto ima_g = mln::view::green(ima);
   auto ima_b = mln::view::blue(ima);
   

		ima	red(ima), green(ima), blue(ima)
Category	Forward	X	X
	Bidirectional	X	X

	Indexable	X	X

Examples

• Set the red channel to max:

mln::image2d<mln::rgb8> ima = {
  { {0, 0, 255}, {0, 0, 255}, {0, 0, 255} },
  { {0, 0, 255}, {0, 0, 255}, {0, 0, 255} },
  { {0, 0, 255}, {0, 0, 255}, {0, 0, 255} }
  };
auto ima_r = mln::view::red(ima);
mln::fill(ima_r, 255);
mln::io::imprint(ima);

Outputs:

(255, 0, 255) (255, 0, 255) (255, 0, 255)
(255, 0, 255) (255, 0, 255) (255, 0, 255)
(255, 0, 255) (255, 0, 255) (255, 0, 255)
