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

1. template<typename T>
   auto cast<T>(Image ima)
   

   1. Makes a view from ima where for each pixel value evals to out(p) = static_cast<T>(ima(p))

   Parameters:

   ima – Input range

   Template Parameters:

   T – Type to cast to

   mln::image2d<double> ima = ...;
   auto g1 = mln::view::cast<int>(ima);
   

		ima	cast<T>(ima)
Category	Forward	X	X
	Bidirectional	X	X
	Raw	X
Properties	Writable	X
	Accessible	X	X
	Indexable	X	X

Examples

• Double image to int:

mln::image2d<double> input = { {0.1, 1.1, 2.1}, {3.5, 4.5, 5.5} };
auto g = mln::view::cast<int>(input);
mln::io::imprint(g);

Outputs:

0 1 2
3 4 5
