6.2. Plot area and unit setting instructions
Instruction Function

IR Input relative scaling points
SC Scale
IW Input window
RO Rotate coordinate system
IP - Input Scaling Point

•
The coordinates used are absolute values in graphics units.
•
Sets the location of the scaling points(P1,P2).
•
Coordinate values for P1
X
,P1
Y,
P2
X
and P2
Y
are given as the integer numbers.
•
You can set P1 and P2 to be anywhere that the range of allowable coordinates permits. However, only parts
of resulting images that lie within the effective window will be printed.
•
The default location of P1 is the lower left corner and P2 is the upper right corner of the PCL picture frame.
•
Using this instruction without a parameter field initializes the scaling points(P1,P2) to the default location.
•
P2
X
and P2
Y
may be omitted. (If P2
X
and P2
Y
are omitted, P2 is set automatically so as not to alter the
distance between P1 and P2).
•
If P2x and P2y are omitted P2 is set to be in the same position relative to P1 that it was before the command
was invoked.
•
The IP command remains in effect until another IP command, an IR command or an IN command is used.
