Select Current Pattern Command
The Select Current Pattern command identifies the type of pattern to
be applied onto the destination.
? * v # T
This command selects which type of pattern is applied. For values 2,
3, and 4, the desired shading level, cross-hatch pattern, or
user-defined pattern number is identified by the Pattern ID command
described earlier in this chapter.
Note For selecting or changing the current pattern, the Select Current
Pattern (
?*v#T) and the Pattern ID (?*c#G) commands work
together. Sending the current pattern (Select Current Pattern
command) alone does not change the current pattern; the Pattern
ID must be sent first. However, when selecting solid white (white
rule) or solid black (black rule), only the Select Current Pattern
command is required.
Once a current pattern is selected, that pattern applies to all images
placed on the page until a new pattern is selected.
# = 0 - Solid black or foreground color
1 - Solid white
2 - Shading pattern
3 - Cross-hatch pattern
4 - User-defined pattern
Default =0
Range = 0 - 4 (values outside of range are ignored)
