Generate
========

Include :file:`<mln/core/algorithm/generate.hpp>`

.. cpp:namespace:: mln

.. cpp:function:: template <class Generator> void generate(OutputImage out, Generator g)

    Assigns each value in the image with a value generated by the given function object `g`.
    This is equivalent to the following code::

        for (auto& vout : out.values())
            vout = g();


    :param out: The output image.
    :param g: The value generator.
    :tparam OutputImage: A model of :cpp:concept:`OutputImage`
    :tparam Generate: A model of :cpp:concept::`std::Generator`


Examples
--------

#. Generate random values in the image:


    std::default_random_engine e1(r());
    std::uniform_int_distribution<int> g;

    mln::image2d<int> ima(10, 10);
    mln::generate(ima, g);
  
 
Complexity
----------

Linear in the number of pixels.
