示例1: Rectangle
Public Sub Complement_Region_Example(ByVal e As PaintEventArgs)
' Create the first rectangle and draw it to the screen in black.
Dim regionRect As New Rectangle(20, 20, 100, 100)
e.Graphics.DrawRectangle(Pens.Black, regionRect)
' Create the second rectangle and draw it to the screen in red.
Dim complementRect As New Rectangle(90, 30, 100, 100)
e.Graphics.DrawRectangle(Pens.Red, complementRect)
' create a region from the first rectangle.
Dim myRegion As New [Region](regionRect)
' Create a complement region.
Dim complementRegion As New [Region](complementRect)
' Get the complement of myRegion when combined with
' complementRegion.
myRegion.Complement(complementRegion)
' Fill the complement area with blue.
Dim myBrush As New SolidBrush(Color.Blue)
e.Graphics.FillRegion(myBrush, myRegion)
End Sub
示例2: Rectangle
Public Sub Complement_RectF_Example(ByVal e As PaintEventArgs)
' Create the first rectangle and draw it to the screen in black.
Dim regionRect As New Rectangle(20, 20, 100, 100)
e.Graphics.DrawRectangle(Pens.Black, regionRect)
' Create the second rectangle and draw it to the screen in red.
Dim complementRect As New RectangleF(90, 30, 100, 100)
e.Graphics.DrawRectangle(Pens.Red, _
Rectangle.Round(complementRect))
' Create a region using the first rectangle.
Dim myRegion As New [Region](regionRect)
' Get the complement of the region combined with the second
' rectangle.
myRegion.Complement(complementRect)
' Fill the complement area with blue.
Dim myBrush As New SolidBrush(Color.Blue)
e.Graphics.FillRegion(myBrush, myRegion)
End Sub
示例3: Rectangle
Public Sub Complement_Path_Example(ByVal e As PaintEventArgs)
' Create the first rectangle and draw it to the screen in black.
Dim regionRect As New Rectangle(20, 20, 100, 100)
e.Graphics.DrawRectangle(Pens.Black, regionRect)
' Create the second rectangle and draw it to the screen in red.
Dim complementRect As New Rectangle(90, 30, 100, 100)
e.Graphics.DrawRectangle(Pens.Red, complementRect)
' Create a graphics path and add the second rectangle to it.
Dim complementPath As New GraphicsPath
complementPath.AddRectangle(complementRect)
' Create a region using the first rectangle.
Dim myRegion As New [Region](regionRect)
' Get the complement of myRegion when combined with
' complementPath.
myRegion.Complement(complementPath)
' Fill the complement area with blue.
Dim myBrush As New SolidBrush(Color.Blue)
