Fill

Include <mln/core/algorithm/fill.hpp>

template<class V>
void fill(OutputImage ima, const V &value)

Assign the value value to each pixel of the image. This is equivalent to the following code:

for (auto& vout : ima.values())
    vout = value;

This function has a parallel implementation, see following section for an example.

Parameters:

• ima – The image to be filled.

• value – The value to fill with.

Template Parameters:

• V – Must be convertible to image_value_t<OutputImage>

• OutputImage – A model of OutputImage

Examples

1. Set the pixels to a color:

   mln::image2d<mln::rgb8> f = ...;
   mln::fill(f, mln::rgb8{255,0,0});
   

2. Set the red component of a RGB image:

   mln::image2d<mln::rgb8> f = ...;
   mln::fill(mln::view::red(f), 69);
   

3. Using parallel fill to set the pixels to a color:

   mln::image2d<mln::rgb8> f = ...;
   mln::parallel::fill(f, mln::rgb8{255,0,0});
   

Complexity

Linear in the number of pixels.
