Filling with Patterns
The procedure for applying patterns to text, raster images, and
rectangular areas is essentially the same, except that for text and
raster images the Current Pattern (
?*v#T) command is used, and for
rectangular areas the Fill Rectangular Area (
?*c#P) command is
used. The procedures below describe how to fill with PCL and
HP-GL/2 patterns.
Patterns for Text and Raster Images
Use the following general procedure to fill text and raster images with
a non-solid pattern.
1 Specify the Pattern ID (
?*c#G) command. For HP-defined
patterns, select an ID that specifies the desired pattern.
2 Download the pattern (
?*c#W). This step is for user-defined
patterns only. The downloaded pattern adopts the current
pattern ID.
3 Apply the pattern to all subsequent text and raster images.
Specify the current pattern type (
?*v#T).
Patterns for Rectangles
Use the following general procedure to apply a non-solid pattern to
rectangular areas.
1 Specify the Pattern ID (
?*c#G). For HP-defined patterns, select
an ID that matches an HP-defined pattern.
2 Download the pattern (
?*c#W). This step is for user-defined
patterns only. The downloaded pattern adopts the current
pattern ID.
3 Define the rectangle. Position the cursor and specify the
rectangle size (
?*c#A, ?*c#B or ?*c#H, ?*c#V).
4 Apply the pattern to the rectangle. Send the Fill Rectangular Area
command (
?*c#P).
HP-GL/2 Patterns
PCL patterns can be used in HP-GL/2 mode, but HP-GL/2 patterns
cannot be used in PCL mode. Using HP-GL/2, patterns are
downloaded using the RF (Raster Fill) command, and applied using
the FT (Fill Type) or SV (Screened Vectors) commands.
