示例1: Complement_Region_Example
public void Complement_Region_Example(PaintEventArgs e)
{
// Create the first rectangle and draw it to the screen in black.
Rectangle regionRect = new Rectangle(20, 20, 100, 100);
e.Graphics.DrawRectangle(Pens.Black, regionRect);
// Create the second rectangle and draw it to the screen in red.
Rectangle complementRect = new Rectangle(90, 30, 100, 100);
e.Graphics.DrawRectangle(Pens.Red, complementRect);
// Create a region from the first rectangle.
Region myRegion = new Region(regionRect);
// Create a complement region.
Region complementRegion = new Region(complementRect);
// Get the complement of myRegion when combined with
// complementRegion.
myRegion.Complement(complementRegion);
// Fill the complement area with blue.
SolidBrush myBrush = new SolidBrush(Color.Blue);
e.Graphics.FillRegion(myBrush, myRegion);
}示例2: Complement_RectF_Example
public void Complement_RectF_Example(PaintEventArgs e)
{
// Create the first rectangle and draw it to the screen in black.
Rectangle regionRect = new Rectangle(20, 20, 100, 100);
e.Graphics.DrawRectangle(Pens.Black, regionRect);
// Create the second rectangle and draw it to the screen in red.
RectangleF complementRect = new RectangleF(90, 30, 100, 100);
e.Graphics.DrawRectangle(Pens.Red,
Rectangle.Round(complementRect));
// Create a region using the first rectangle.
Region myRegion = new Region(regionRect);
// Get the complement of the region combined with the second
// rectangle.
myRegion.Complement(complementRect);
// Fill the complement area with blue.
SolidBrush myBrush = new SolidBrush(Color.Blue);
e.Graphics.FillRegion(myBrush, myRegion);
}示例3: Complement_Path_Example
public void Complement_Path_Example(PaintEventArgs e)
{
// Create the first rectangle and draw it to the screen in black.
Rectangle regionRect = new Rectangle(20, 20, 100, 100);
e.Graphics.DrawRectangle(Pens.Black, regionRect);
// Create the second rectangle and draw it to the screen in red.
Rectangle complementRect = new Rectangle(90, 30, 100, 100);
e.Graphics.DrawRectangle(Pens.Red, complementRect);
// Create a graphics path and add the second rectangle to it.
GraphicsPath complementPath = new GraphicsPath();
complementPath.AddRectangle(complementRect);
// Create a region using the first rectangle.
Region myRegion = new Region(regionRect);
// Get the complement of myRegion when combined with
// complementPath.
myRegion.Complement(complementPath);
// Fill the complement area with blue.
SolidBrush myBrush = new SolidBrush(Color.Blue);
e.Graphics.FillRegion(myBrush, myRegion);
