Rectangular Area
Fills (Rules)
Rectangular area fills are a special case of source images—
the source transparency mode has no effect, since the
printer treats the rectangular area as a solid “black” (all 1’s)
source.
Rectangular areas may be filled using patterns or textures.
The current Pattern ID (?*c#G) selects the pattern, and the
Fill Rectangular Area command (?*c#P) tiles an area
whose dimensions are specified by the Vertical and
Horizontal Rectangle size commands (?*c#A, ?*c#B,
?*c#H, ?*c#V). The rectangular area does not exist and
cannot be printed until the Fill Rectangular Area command
(?*c#P) has been issued, even though the rectangular area
has been specified.
Filling a rectangular area does not change the current
active cursor position (CAP). The filled rectangular area is
not affected by end-of-line wrap, perforation skip mode, or
margins. A rectangular area may extend beyond the
margins, but it will be clipped to the printable area of the
logical page. Rectangular areas are not affected by graphics
resolution (?*t#R).
Except for the absence of white pixels in the source, pattern
transparency operates the same way for rectangular area
fills as for other sources. The non-white pixels of the
pattern are poured through the entire rectangular area onto
the destination. The white bits of the pattern are either
applied or ignored, based on the pattern transparency
mode. If foreground color is used, it is applied to the
non-white bits of the pattern prior to pouring (except for
user-defined color patterns).
Note The Pixel Placement command (?*l #R) affects rules.
The commands used to print rectangular area fills are
described beginning on the next page.
