Examples

The following example shows how to use the CopyTo method on the BitmapSource class to convert a PNG image into a Texture. The PNG image is stored as a resource. CubeSample is the name of the project and SLXNA.png is the name of the image.

// Load image
Stream imageStream = Application.GetResourceStream(
    new Uri(@"CubeSample;component/SLXNA.png", UriKind.Relative)).Stream;

BitmapImage image = new BitmapImage();
image.SetSource(imageStream);

// Create texture
Texture2D texture = new Texture2D(
                          resourceDevice, 
                          image.PixelWidth, 
                          image.PixelHeight,
                          false, 
                          SurfaceFormat.Color);

// Copy image to texture
image.CopyTo(texture);
