In a form I draw a graph. This graph has some distinct paths that should have differently drawn. Say AxesPath, SalesPath, CostsPath etc...

When I resize the form need I to scale every of components Paths?

Take an example:

Imports System.Drawing.Drawing2D

Public Class Form1
  Dim lineOne As GraphicsPath
  Dim lineTwo As GraphicsPath
  Dim allPaths As GraphicsPath
  Dim initSize As Size

  Public Sub New()

    ' This call is required by the designer. '
    InitializeComponent()

    initSize = Me.Size

    lineOne = New GraphicsPath()
    lineTwo = New GraphicsPath()

    lineOne.AddLine(20.0F, 20.0F, Me.initSize.Width - 20.0F, 20.0F)
    lineTwo.AddLine(0.1F, 10.0F, Me.initSize.Width - 20.0F, _ 
        Me.initSize.Height - 0.5F)
    allPaths = New GraphicsPath()
    allPaths.AddPath(lineOne, False)
    allPaths.AddPath(lineTwo, False)

    Me.ResizeRedraw = True
  End Sub

  Protected Overrides Sub OnResize(ByVal e As System.EventArgs)
    MyBase.OnResize(e)
    Dim m As New Matrix
    m.Scale(Me.Width / initSize.Width, Me.Height / initSize.Height)

    allPaths.Transform(m)

    initSize = Me.Size
  End Sub

  Protected Overrides Sub OnPaint(ByVal e As PaintEventArgs)
    MyBase.OnPaint(e)

    ' WORKS '
    ' e.Graphics.DrawPath(Pens.GreenYellow, allPaths) '

    ' DOES NOT WORK! '
    e.Graphics.DrawPath(Pens.DarkGoldenrod, lineOne)
    e.Graphics.DrawPath(Pens.DarkMagenta, lineTwo)
  End Sub
End Class
