HP PCL Graphics Commands 9-41
Chord angle - Specifies the chord angle used to draw the arc. The default chord angle is 5
o
.
The chord angle specifies, in degrees, the maximum angle created when lines from each of
the chord intersect the center point of the circle. The smaller the chord angle, the smoother
the curve.
Edge Rectangle Absolute (EA)
EA X , Y [ ; ]
This command defines and outlines a rectangle using absolute coordinates. Use the EA
command when drawing charts or schematic diagrams that require rectangles.

The EA command defines the edges of a rectangle using absolute coordinates and the
current pen, line type, and line attributes. The EA command performs an automatic pen
down. When command execution completes, the original pen location and up/down status
are restored.
The X, Y coordinates specify the opposite corner of the rectangle from the current pen
location. The current pen location is the starting point of a rectangle. Coordinates are
interpreted in current units: as user-units when scaling is on; as plotter units when scaling
is off.
The only difference between the EA command and the RA (fill rectangle absolute)
command is that the EA command produces an outlined rectangle; RA produces a filled
rectangle.
Fill Rectangle Absolute (RA)
RA X , Y [ ; ]
This command defines and fills a rectangle using absolute coordinates. Use the RA
command to fill rectangular shapes in drawings. (To outline a rectangle using absolute
coordinates, use the EA command).
