The valueof nmust be non-negative; if necessary it is truncatedto the value
of (logicalpage width) -(x coordinate of cursor). It will clip all raster rows
longerthan the specified width, evenif n=O.Itwill padany row shorter than
thespecified widthwith zeros. The area maps to eitheropaque ortransparent
depending on the source transparency mode.
Thedefault value is thewidth or length ofthe logical page, depending on the
orientation.The command is ignored when received between start and end

Print shopscall lines of any thickness rules. Aprinted line in fact is arec-
tangulararea with one “skinny”dimension, from oneto many dotsthick. We
will use the word “rules” too, to avoid confusion with the lines used to
measure pages.
You follow these three steps when you use rule and pattern graphics:
1)Definethe dimensions you need.
2)Choose the graphics pattern you want to fill in those dimensions.
3) Print the pattern.
Remember to send the following rule or pattern commands in thatorder.
