HP 5961-0509 manual Example, Circle with a 500 plu radius and a 5 default, Exit polygon mode

The FP command fills between points defined with either the pen down or the pen up. The polygon is filled using the current pen, fill type, line type and attributes (if the fill type is not raster). The FP command includes an automatic pen down. When the command execution is complete, the original pen location and up/down status are restored.

The example on the next page creates a polygon composed of two subpolygons. In this case, the FP command fills alternating areas, beginning with the outside area.

Table 21-17 Example

?E	Reset the printer.
?%0B	Enter HP-GL/2 mode.
IN;	Initialize HP-GL/2 mode.
SP1;	Select pen number 1. Even though there is no
	physical pen, the SP command must be used
	to enable printing.
PA1500,1500;	Specify absolute plotting and move to
	(1500,1500).
PM0;CI1000,60;	Enter the polygon mode, store a circle with
PA1500,1500;	radius of 1000 plu and a 60° chord angle,
CI500;PM2;	store a pen move to (1500,1500), and another
	circle with a 500 plu radius and a 5° (default)
	chord angle. Close the current polygon and
	exit polygon mode.
LT4;FT3,50,45;	Select line type 4 and fill type 3. Specify a 50
	plu distance between the fill lines, and slant
	the lines at a 45° angle.
FP;	Using even-odd fill method, fill the polygon
	currently in the polygon buffer with the line
	and fill types just specified.
?%0A	Enter the PCL mode.
?E	Send a reset to end the job and eject the page.
