示例1: SetSigmaBellShapeExample
Public Sub SetSigmaBellShapeExample(ByVal e As PaintEventArgs)
' Create a graphics path and add a rectangle.
Dim myPath As New GraphicsPath
Dim rect As New Rectangle(100, 20, 100, 50)
myPath.AddRectangle(rect)
' Get the path's array of points.
Dim myPathPointArray As PointF() = myPath.PathPoints
' Create a path gradient brush.
Dim myPGBrush As New PathGradientBrush(myPathPointArray)
' Set the color span.
myPGBrush.CenterColor = Color.Red
Dim mySurroundColor As Color() = {Color.Blue}
myPGBrush.SurroundColors = mySurroundColor
' Draw the brush to the screen prior to blend.
e.Graphics.FillRectangle(myPGBrush, 10, 10, 200, 200)
' Set the Blend factors.
myPGBrush.SetSigmaBellShape(0.5F, 1.0F)
' Move the brush down by 100 by applying the translate
' transform to the brush.
myPGBrush.TranslateTransform(0, 100, MatrixOrder.Append)
' Draw the brush to the screen again after setting the
' blend and applying the transform.
e.Graphics.FillRectangle(myPGBrush, 10, 10, 300, 300)
