                      int y)

Draws the given single band image onto the specific band at the given position. Side-affects this image. The single band image must be of the same type as the bands within this image.

Parameters:

image - A SingleBandImage to draw

band - The band onto which the image will be drawn

x - The x-coordinate for the top-left of the drawn image

y - The y-coordinate for the top-left of the drawn image
