Determining the size of a path drawn image

[Napivo1972]

I use the following Paint Event to draw a vector graphics image.

 

   Private Sub Form1_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles MyBase.Paint
       Dim p As New Pen(Color.Black, 1)
       e.Graphics.TranslateTransform(-hsb.Value * 10, -vsb.Value * 10)
       Dim m As New Matrix
       m.Scale(zoom, zoom)
       zoom = 1
       Dim t1 As Integer
       Dim pth As GraphicsPath
       For t1 = 0 To 0
           For Each pth In y(t1).gPaths
               pth.Transform(m)
               e.Graphics.DrawPath(p, pth)
           Next
       Next
       For t1 = 5 To 5
           For Each pth In y(t1).gPaths
               e.Graphics.DrawPath(p, pth)
           Next
       Next
   End Sub

 

This works great but I need to find the height and the width of the drawn picture to set the scroll bars min and max values.

 

Does any of you have an easy method to do this?

Maybe using GraphicsPath.GetBounds()?

thanks Ming_Lei You put me on the right track.

 

Dim rect As RectangleF

rect = RectangleF.Union(rect, pth.GetBounds)

 

Works like a charm
