) [virtual]

Get the pixel data of an image, transmitted as RGBRGBRGB. It is the caller's responsibility to delete the resulting array. It is very important to realize that the memory in this array is organized from the bottom of the window to the top. The origin of the screen is in the lower left corner. The y axis increases as you go up the screen. So the storage of pixels is from left to right and from bottom to top. To maintain the same prototype as in vtkRenderWindow, the last argument is provided, but currently not used.
