GDI+: GdipGetTextureWrapMode

[José Roca]

The following example creates a texture brush, sets the wrap mode of the brush, and uses the brush to fill a rectangle. Next, the code gets the wrap mode of the brush and stores the value. The code creates a second texture brush and uses the stored wrap mode to set the wrap mode of the second texture brush. Then, the code uses the second texture brush to fill a rectangle.

   Image image(L"HouseAndTree.gif");
   TextureBrush textureBrush(&image);
   textureBrush.SetWrapMode(WrapModeTileFlipX);
   graphics.FillRectangle(&textureBrush, 0, 0, 200, 200);

   // Get the brush's wrap mode.
   WrapMode wrapMode = textureBrush.GetWrapMode();
   
   // Create a second texture brush with the same wrap mode.
   Image image2(L"RainbowR.bmp");
   TextureBrush textureBrush2(&image2);
