Paste

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

void paste(InputImage src, OutputImage dst)

Paste the values from the source image src to destination image dst considering the location. This is equivalent to the following code:

for (auto px : src.pixels())
    dst(px.point()) = px.val();

The source and destination images should not alias. This function has a parallel implementation, see following section for an example.

Parameters:

src – The source image
dst – The destination image

Template Parameters:

InputImage – A model of InputImage
OutputImage – A model of OutputImage and AccessibleImage.

Preconditions

The domain of src must be include in the domain of dst.

Examples

Paste a part of the image into a larger one:

mln::image2d<mln::rgb8> f = lena();
mln::image2d<mln::rgb8> g(f, mln::init());
mln::box2d roi = {{50,50}, {100,100}};
mln::paste(mln::view::clip(f, roi), g);

Using parallel paste to paste a part of the image into a larger one:

mln::image2d<mln::rgb8> f = lena();
mln::image2d<mln::rgb8> g(f, mln::init());
mln::box2d roi = {{50,50}, {100,100}};
mln::parallel::paste(mln::view::clip(f, roi), g);

Complexity

Linear in the number of pixels in src.
