		int	y,
		int	x2,

		int	front
	)

pure virtual

Get the pixel data of an image, transmitted as RGBRGBRGB. The front argument indicates if the front buffer should be used or the back buffer. 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. (x,y) is any corner of the rectangle. (x2,y2) is its opposite corner on the diagonal.

Implemented in vtkOpenGLRenderWindow, and vtkOpenGLRenderWindow.
