SCALE

PSC

CALL SEQUENCE

CALL PSC (FX, FY, ERRIND, XFRMT)

INPUT PARAMETERS

REAL FX, FY

Real values defining the scale factor. Each value is applied individually to the X, Y components.

OUTPUT PARAMETERS

INTEGER ERRIND

Error indicator

REAL XFRMT(3,3)

Resulting homogeneous 3 x 3 matrix.

PHIGS STATE

EFFECT

Returns a homogeneous 3 x 3 matrix to be used for the 2D scaling defined by FX, FY.

The returned matrix can be used as the transformation matrix for the SET LOCAL TRANSFORMATION MATRIX, SET GLOBAL TRANSFORMATION MATRIX and similar functions.

ERRORS

2

Ignoring function, function requires state (PHOP, *,*,*)
