Clip (View)

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

1. auto clip(Image ima, Domain dom)
   

   1. Makes a view that clip the original image to a sub-domain. A pixel is kept if and only if dom.has(p.point()) is true.

   Parameters:

   • ima – Input range

   • dom – Input range of point

   mln::image2d<int> ima = ...;
   mln::image2d<bool> mask = ...;
   auto g = mln::view::mask(ima, mask);
   

		ima	clip(ima, dom)
Category	Forward	X	X
	Bidirectional	X	X
	Raw	X
Properties	Writable	X	X
	Accessible	X	X
	Indexable	X	X

Examples

• Set a sub-domain to 42:

mln::image2d<int> ima = { {0, 1, 2}, {3, 4, 5}, {6, 7, 8} };
box2d d = {{0, 0}, {1, 1}};
auto g = mln::view::clip(ima, d);
mln::fill(g, 42);
mln::io::imprint(ima);

Outputs:

42 42 2
42 42 5
6  7  8

• Set all odd values to 42:

mln::image2d<int> ima = { {0, 1, 2}, {3, 4, 5}, {6, 7, 8} };
auto odd_d = mln::where(ima % 2 == 1);
auto g = mln::view::clip(ima, odd_d);
mln::fill(g, 42);
mln::io::imprint(ima);

Outputs:

0  42 2
42 4  42
6  42 8
