Matrix.SkewPrepend(Double, Double) Method

Definition

Prepends a skew of the specified degrees in the x and y dimensions to this Matrix structure.

public:
 void SkewPrepend(double skewX, double skewY);
public void SkewPrepend (double skewX, double skewY);
member this.SkewPrepend : double * double -> unit
Public Sub SkewPrepend (skewX As Double, skewY As Double)

Parameters

skewX
Double

The angle in the x dimension by which to skew this Matrix.

skewY
Double

The angle in the y dimension by which to skew this Matrix.

Examples

This example shows how to prepend a skew to a Matrix structure.

private Matrix skewPrependExample()
{
    
    Matrix myMatrix = new Matrix(5, 10, 15, 20, 25, 30);
    
    myMatrix.SkewPrepend(45, 180);

    // myMatrix is equal to (5, 10, 20, 30, 25, 30).
    return myMatrix;
}

Remarks

In a composite transformation, the order of individual transformations is important. For example, if you first rotate, then scale, then translate, you get a different result than if you first translate, then rotate, then scale. One reason order is significant is that transformations like rotation and scaling are done with respect to the origin of the coordinate system. Scaling an object that is centered at the origin produces a different result than scaling an object that has been moved away from the origin. Similarly, rotating an object that is centered at the origin produces a different result than rotating an object that has been moved away from the origin.
