QM_SkewMatrix

QM_SkewMatrix(matrixRec; skewH; skewV; anchorH; anchorV):error
	matrixRec	Array real	Matrix record
	skewH	Real	Horizontal skew amount
	skewV	Real	Vertical skew amount
	anchorH	Real	Horizontal coordinate of the anchor point
	anchorV	Real	Vertical coordinate of the anchor point
	error	Longint	Error result

Adds a skew transformation to a matrix record.

Parameter matrixRec specifies the matrix. It must be declared as a 3 x 3 array of reals. QMedia updates and returns the contents matrixRec with the specified scaling operation.

Parameters skewH and skewV specify the horizontal and vertical skew values respectively.

Parameters anchorH and anchorV specify the horizontal and vertical coordinates of the anchor point.
