IW - Window
IW [ X1, Y1, X2, Y2 ] [;]
X
1
-Window lower left X coordinate
Y
1
-Window lower left Y coordinate
X
2
-Window upper right X coordinate
Y
2
-Window upper right Y coordinate
•
This instruction sets the window inside which drawing can be performed (the soft clip limits).
•
Coordinates are specified in current units.
•
Using this instruction with no parameters sets the window to be the same as the picture frame.
•
You can set the corners of the window to lie outside the picture frame. However, only the portion of the
image which lies within both the picture frame and the window will appear on the page.
•
If scaling is turned on with the SC command before the window is defined with the IW command, you can
move the window on the physical page by specifying different locations for P1 and P2 with the IP and IR
commands. The user unit coordinates that bound the window remain the same.
•
If an SC command is used after the IW window definition, the window is fixed on the physical page and
does not move when subsequent IP and IR commands are invoked.
•
An IW command remains in effect until another IW command is issued, until default settings are restored
with the DF command or until the printer is initialized with an IN command.

RO - Rotate coordinate system
RO [
q
][;]
q
: Angle in degrees through which the coordinate system is rotated.
•
This instruction is used to rotate the graphics coordinate system anti-clockwise.
•
Using this instruction with no parameter sets the rotation of the coordinate system to 0 degrees (default
value).
•
The pen position does not change.
•
P1 and P2 rotate with the coordinate system and retain the same coordinate values.
•
To relocate P1 and P2 at the lower left and upper right hand corners of the picture frame, use the IP or IR
commands.
•
If you have previously used an IW command, the window is also rotated. Any part of the window that
falls outside the hard clip limits will be clipped.
•
The command remains in effect until another RO command is used or until the printer is initialized with the IN
instruction.
•
Valid values of
q
are 0, 90, 180 or 270.
