### 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.
