GDI+: GdipCloneImage

[José Roca]

The following example creates an Image object based on a JPEG file. The code creates a second Image object by cloning the first. Then the code calls the GdipDrawImage function twice to draw the two images.

   // Create an Image object, and then clone it.
   Image image1(L"Crayons.jpg");
   Image* pImage2 = image1.Clone();

   // Draw the original image and the cloned image.
   graphics.DrawImage(&image1, 20, 20);
   graphics.DrawImage(pImage2, 250, 20);

   delete pImage2;
