Rectangle.Inflate Method (Int32, Int32)

 

Enlarges this Rectangle by the specified amount.

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

public void Inflate(
	int width,
	int height
)

Parameters

width
Type: System.Int32

The amount to inflate this Rectangle horizontally.

height
Type: System.Int32

The amount to inflate this Rectangle vertically.

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.

If either x or y is negative, the Rectangle structure is deflated in the corresponding direction.

The following example creates a Rectangle structure and enlarges it by 100 units in the x-axis direction:

public void RectangleInflateTest3(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);

    // Call Inflate.
    rect.Inflate(50, 50);

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