I'm having a problem drawing this graphic:
point_wrong.png

For some reason I'm getting two points instead of just the one.

The code for it:
Code:
Private Function RoundedPoint(ByVal Rect As Rectangle, ByVal CornerSize As Integer) As GraphicsPath
        Dim _GraphicsPath As New Drawing2D.GraphicsPath()

       

        _GraphicsPath.AddArc(New Rectangle(40, 0, CornerSize, CornerSize), 180, 90)
        _GraphicsPath.AddLine(CornerSize, 0, (Rect.Width + 40) - CornerSize, 0)

        _GraphicsPath.AddArc(New Rectangle(Rect.Width - CornerSize, 0, CornerSize, CornerSize), -90, 90)
        _GraphicsPath.AddLine(Rect.Width, CornerSize, (Rect.Width + 40), Rect.Height - CornerSize)

        _GraphicsPath.AddArc(New Rectangle(Rect.Width - CornerSize, Rect.Height - CornerSize, CornerSize, CornerSize), 0, 90)
        _GraphicsPath.AddLine((Rect.Width + 40) - CornerSize, Rect.Height, CornerSize, Rect.Height)

        _GraphicsPath.AddArc(New Rectangle(40, Rect.Height - CornerSize, CornerSize, CornerSize), 90, 90)

        'Create Point
        Dim CenterPoint As Point = New Point(Rect.X, Rect.Height / 2)
        Dim Point3 As Integer = Rect.Height / 3
        _GraphicsPath.AddLine(40, Rect.Height - Point3, 0, CenterPoint.Y)
        _GraphicsPath.AddLine(0, CenterPoint.Y, 40, Point3)

        Return _GraphicsPath
    End Function
If I comment out the point part the shape is correct, jut a rounded rectangle with no points. What am I doing that is causing the wrong point?

Hi Sorwen,

I am not compleet sure but I think this is the line where it goes wrong.

_GraphicsPath.AddLine(Rect.Width, CornerSize, (Rect.Width + 40), Rect.Height - CornerSize)

You want to go down, but the X values are diffrent and should be the same.
(Rect.Width + 40) Should be Rect.Width

Good luck,

Ernst Jan
 
You were right. Thank you. I had been looking at the code so long I never noticed it. I also learned that technically I can remove all the +40. As long as the arcs are in the correct spot when it fills the shape it ignores any overage. I left all of the correct ones in just to be on the safe side though.

Hi Sorwen,

Glad to be of some help to you.
