[RESOLVED] System.Windows.Media... AreaGradient ?

[boops boops]

You could make something a bit like that in WPF just by blurring a rectangle.

     Dim r As New Rectangle With {.Width = 250, .Height = 250, .Fill = Brushes.Red}
     r.Effect = New Effects.BlurEffect With {.Radius = 25, .RenderingBias = Effects.RenderingBias.Quality}
     Dim vb As New VisualBrush With {.Stretch = Stretch.None, .Visual = r}
    'use a Canvas or other control to display the resulting brush:
    Canvas1.Background = vb

result:


Admittedly, this lacks the pointy corners of your post #3 image. If those features are wanted, you could piece the triangles together using a DrawingContext, which is the WPF equivalent of a System.Drawing.Graphics object, as you did in GDI+. I don't have time now to work out the actual drawing code required now, but this should give you a rough idea of how to create the brush:

    Dim dv As New DrawingVisual
      Dim dc As DrawingContext = dv.RenderOpen
      'insert drawing instructions here
      dc.Close()
    Dim vb As New VisualBrush With {.Stretch = Stretch.None, .Visual = dv}
