User-Defined Pattern Graphics
In addition to the eight shading patterns and six cross-hatch patterns,
users can design their own patterns (area fill). These user-defined
patterns are downloaded to the printer and controlled using three
new commands:

User-Defined Pattern Implementation
To create a user pattern, a user defines a binary raster data image
as a base pattern. This base pattern is downloaded to the printer
using the User-Defined Pattern command. Prior to downloading the
pattern, a Pattern ID command is sent to assign the user pattern an
ID number. This ID number is used to select the pattern for printing
and for pattern management.
To apply the pattern to an image, the printer duplicates or tiles (like
placing ceramic tiles) the pattern across and down the page. This
pattern can be applied to any image, or used as rectangular area fill.
Figure 13-6 User-Defined Base Pattern Example
A user-defined pattern may be applied to any image in the same
manner as the internal (cross-hatch or shade) patterns.
