Drawing2D.GraphicsPath

[rbulph]

Does the GraphicsPath have any method for determining whether a given point is within a certain distance of any point on the path? This would seem quite a natural facility for it to provide, but I can't see it anywhere. In its absence it looks as if I will have to call the Flatten method and then test for each pair of points as if they were a short line.

Easy:

 

Public Class Form1
   Dim gp As Drawing2D.GraphicsPath

   Private Sub Form1_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles Me.Paint

       gp = New Drawing2D.GraphicsPath
       gp.AddArc(New Rectangle(50, 50, 200, 200), 0, 145)
       gp.AddLine(gp.GetLastPoint, New Point(100, 100))

       e.Graphics.DrawPath(Pens.Blue, gp)

   End Sub

   Private Sub Form1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseMove
       Dim hp As New Pen(Color.Black, 6)    'Thickness of hypothetical pen is subjective, but 6 seems about right.
       If gp.IsOutlineVisible(e.Location, hp) Then
           Me.Cursor = Cursors.Cross
       Else
           Me.Cursor = Cursors.Default
       End If
   End Sub

End Class
