EN EP, Edge Polygon 21-21
EP, Edge Polygon
This command outlines the polygon currently stored in the polygon
buffer. Use EP to edge polygons that you defined in polygon mode
and with the Fill Rectangle and Wedge Commands (RA, RR, and
WG).
EP [;]
The EP command outlines any polygon that is currently in the
polygon buffer. This includes wedges and rectangles defined using
the EA, ER, EW, RA, RR, and WG commands. EP accesses the data
in the polygon buffer, but does not clear the buffer or change the data
in any way.
The EP command only edges between points that were defined with
the pen down, using the current pen, line type and attributes. When
the command execution is complete, the original pen location and
up/down status are restored.
The following example creates a shape in polygon mode, then uses
EP to outline it.
Table 21-10 Example: Using the EP Command
?E Reset the printer.
?%0B Enter HP-GL/2 mode.
IN; Initialize HP-GL/2 mode.
SP1; Select pen number 1 (black).
PA2000,10; Specify absolute plotting and move to
position (2000,10).
PM0;PD10,2000,10,10,
2000,10;PM1;
Enter polygon mode, store a pen down
command, and then store points
(10,2000), (10,10), and (2000,10).
Close the polygon.
PU610,610; CI500;PM2; While still in polygon mode, lift the pen
and move to (610,610). Draw a circle
with a diameter of 500 plu, then close
the current subpolygon and exit polygon
mode.
