GDI+: GdipGetTextureImage

[José Roca]

The following example creates a texture brush and uses it to fill an ellipse. The code then gets the brush's image and draws it.

   // Create a texture brush, and use it to fill an ellipse.
   Image image(L"sample.jpg");
   TextureBrush textureBrush(&image);
   graphics.FillEllipse(&textureBrush, 0, 0, 200, 100);

   // Get the brush's image, and draw that image.
   Image* pImage = textureBrush.GetImage();
   graphics.DrawImage(pImage, 10, 150);
