IP - Input scaling point
IP [ P1X, P1Y [,P2X, P2Y]] [;]
P1X ; X coordinate of P1 P1Y ; Y coordinate of P1
P2X ; X coordinate of P2 P2Y ; Y coordinate of P2
The coordinate values used are absolute values in graphics units.
Sets the location of the scaling points(P1, P2).
Coordinate values for P1X, P1Y, P2X and P2Y are given as integer numbers.
The IP instruction is ignored when the set coordinates are outside the print area.
Using this instruction without a parameter field initializes the scaling points(P1, P2).
P2X and P2Y may be omitted. (If P2X and P2Y are omitted, P2 is set automatically so as not to alter the distance
between P1 and P2).
SC - Scale
SC Xmin, Xmax, Ymin, Ymax
Xmin ; X coordinate of P1 Xmax ; X coordinate of P2
Ymin ; Y coordinate of P1 Ymax ; Y coordinate of P2
Sets the scale for the coordinates the user wants to establish.
Coordinate values for Xmin, Xmax, Ymin and Ymax are given as real numbers.
Using this instruction without a parameter field turns the scaling off.
The technical terms user unit and graphics unit as used in this manual are defined as follows;
User unit : the unit of the coordinates set by the SC instruction
Graphics unit : the unit (1/1016 of an inch) of the coordinates not set by the SC
instruction
