Defining the Image Area(PCL Picture Frame)
There is a group of commands that allows you to specify an area on
the page for placing an HP-GL/2 graphic image. These commands
are the Picture Presentation Directives and are used to define a
bounding rectangle to contain the HP-GL/2 image.
Figure 18-1 illustrates the Picture Presentation Directives. The
rectangular area surrounding the image is the PCL Picture Frame
and the location on the page of the PCL Picture Frame is determined
by the picture frame anchor point. Refer to Figures 2-3 and 2-4 for
the default picture frame size.
