9-4 HP PCL Graphics Commands
This command specifies the orientation of the raster image on the logical page.
A value of 0 means that a raster row prints in the positive X-direction of the PCL
coordinate system. (The print direction translates the PCL coordinate system.)
A value of 3 means that the raster graphics prints along the width of the physical page,
regardless of the logical page orientation.
The IntelliBar prints raster graphics along the width of the physical page, regardless of
addressable print area orientation. In portrait orientation, a raster row will be printed in the
positive X-direction of the PCL coordinate system and a subsequent raster row will be
printed beginning at the next dot row position in the positive Y-direction. In landscape
orientation, a raster row will be printed in the positive Y-direction of the PCL coordinate
system and a subsequent raster row will be printed beginning at the next dot row position
in the negative X-direction. Figure 9-3 illustrates a master graphics representation.

#: height in raster rows
Range = 0 to (logical page length – current Y-position of the 0, cursor)
This command specifies the height in raster rows of the raster area. Height is the direction
perpendicular to the direction that raster rows are laid down; height is therefor subject to
the current raster presentation mode and print direction (see “Transfer Raster Data” and
“Start Raster Data” for further information. Unspecified data maps to either white or
transparent, depending on the source transparency mode (see “Select Source Transparency
Mode”).
This command fills the raster area to the full raster height with zeroed rows. Only raster
data appearing within the intersection of the logical page, the printable area, and if set, the
raster width and height, is printed. Data outside the intersection is clipped.
