BD [n1,n2] n1: Image plane of bitplane <last image plane> n2: Bitplane to display <last bitplane>n1 is the image plane onto which an O-map (created with BBT) has been loaded. The data in this image plane are organized in bitplanes.
n2 is the bitplane within the image plane that is to be displayed.
Bitplanes are bit-sliced planes within an image plane, and are numbered 1 to 8. Data are entered into bitplanes with the task BBT to create an O-map. This O-map is then loaded to an image channel on the display before applying this group of interactive bitplane commands in DCP.
