Use getPixels(). To access MagickCore methods preceed them with MagickLib::, for example, MagickLib::GetImagePixels().

Your code only assigns the first pixel, you need to iterate to assign all pixels. Don't forget to call syncPixels() to push the updates to the pixel cache.

syncPixels() just returns but its necessary to ensure the pixel updates are pushed to the pixel cache.

Try

• *q=(*p);
