Rectangle.Inflate Method (Size)

Inflates 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 inflates this rectangle, not a copy of it. The inflation along an axis is in two directions (minus direction and plus direction). For example, if a 50 by 50 rectangle is inflated 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 PaintEventArgs e, which is a parameter of the Paint event handler. The code creates a Rectangle and inflates 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);
