示例1: TransformVectorsExample

Public Sub TransformVectorsExample(ByVal e As PaintEventArgs)
    Dim myPen As New Pen(Color.Blue, 1)
    Dim myPen2 As New Pen(Color.Red, 1)

    ' Create an array of points.
    Dim myArray As Point() = {New Point(20, 20), New Point(120, 20), _
    New Point(120, 120), New Point(20, 120), New Point(20, 20)}

    ' Draw the Points to the screen before applying the
    ' transform.
    e.Graphics.DrawLines(myPen, myArray)

    ' Create a matrix and scale it.
    Dim myMatrix As New Matrix
    myMatrix.Scale(3, 2, MatrixOrder.Append)
    myMatrix.Translate(100, 100, MatrixOrder.Append)
    ListMatrixElementsHelper(e, myMatrix, _
    "Scaled and Translated Matrix", 6, 20)
    myMatrix.TransformVectors(myArray)

    ' Draw the Points to the screen again after applying the
    ' transform.
    e.Graphics.DrawLines(myPen2, myArray)
End Sub

' A helper function to list the contents of a matrix.
Public Sub ListMatrixElementsHelper(ByVal e As PaintEventArgs, _

ByVal y As Integer)

    ' Set up variables for drawing the array
    ' of points to the screen.
    Dim i As Integer
    Dim x As Single = 20
    Dim j As Single = 200
    Dim myFont As New Font("Arial", 8)
    Dim myBrush As New SolidBrush(Color.Black)

    ' Draw the matrix name to the screen.
    e.Graphics.DrawString(matrixName + ":  ", myFont, myBrush, x, y)

    ' Draw the set of path points and types to the screen.
    For i = 0 To numElements - 1
        e.Graphics.DrawString(matrix.Elements(i).ToString() + ", ", _
        myFont, myBrush, j, y)
        j += 30
