Examples
The following example shows how to scale a Matrix structure.
private Matrix scaleExample()
{
Matrix myMatrix = new Matrix(5, 10, 15, 20, 25, 30);
// Scale myMatrix by a horizontal factor of 2
// and a vertical factor of 4 about the origin.
// After this operation,
// myMatrix is equal to (10, 40, 30, 80, 50, 120)
myMatrix.Scale(2, 4);
return myMatrix;
}
private Matrix scaleAboutPointExample()
{
Matrix myMatrix = new Matrix(5, 10, 15, 20, 25, 30);
// Scale myMatrix by a horizontal factor of 2
// and a vertical factor of 4 about the
// point (100,100).
// After this operation,
// myMatrix is equal to (10, 40, 30, 80, -50, -180)
myMatrix.ScaleAt(2, 4, 100, 100);
return myMatrix;
