Bitmap myBitmap = new Bitmap( "Runner.jpg ");

// One hand of the runner
Rectangle sourceRectangle = new Rectangle(80, 70, 80, 45);

// Compressed hand
Rectangle destRectangle1 = new Rectangle(200, 10, 20, 16);

// Expanded hand
Rectangle destRectangle2 = new Rectangle(200, 40, 200, 160);

// Draw the original image at (0, 0).
myGraphics.DrawImage(myBitmap, 0, 0);

// Draw the compressed hand.
myGraphics.DrawImage(
myBitmap, destRectangle1, sourceRectangle, GraphicsUnit.Pixel);

// Draw the expanded hand.
myGraphics.DrawImage(
myBitmap, destRectangle2, sourceRectangle, GraphicsUnit.Pixel);
