SCALE

PSCALE

CALL SEQUENCE

void pscale(

const Pvec	*scale_vector	/* scale vector	*/
Pint	*error_ind	/* (out) error indicator	*/
Pmatrix	result	/* (out) transformation matrix	*/

)

TYPES

typedef struct {
	Pfloat 	delta_x;	/* delta x	*/	Pfloat 	delta_y;	/* delta y	*/
} Pvec;

typedef Pfloat Pmatrix[3][3];

PHIGS STATE

EFFECT

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

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, *,*,*)
