Rectangle.Inflate Method (Size)


Enlarges this Rectangle by the specified amount.

Namespace:   System.Drawing
Assembly:  System.Drawing (in System.Drawing.dll)

public void Inflate(
	Size size


Type: System.Drawing.Size

The amount to inflate this rectangle.

This method enlarges this rectangle, not a copy of it. The rectangle is enlarged in both directions along an axis. For example, if a 50 by 50 rectangle is enlarged by 50 in the x-axis, the resultant rectangle will be 150 units long (the original 50, the 50 in the minus direction, and the 50 in the plus direction) maintaining the rectangle's geometric center.

The following example is designed for use with Windows Forms, and it requires PaintEventArgse, which is a parameter of the Paint event handler. The code creates a Rectangle and enlarges it by 50 units in both axes. The rectangle is drawn to screen before inflation (black) and after inflation (red).

public void RectangleInflateTest2(PaintEventArgs e)

    // Create a rectangle.
    Rectangle rect = new Rectangle(100, 100, 50, 50);

    // Draw the uninflated rectangle to screen.
    e.Graphics.DrawRectangle(Pens.Black, rect);

    // Set up the inflate size.
    Size inflateSize = new Size(50, 50);

    // Call Inflate.

    // Draw the inflated rectangle to screen.
    e.Graphics.DrawRectangle(Pens.Red, rect);
