Rect.Inflate Method (Rect, Size)

 

Returns the rectangle that results from expanding the specified rectangle by the specified Size, in all directions.

Namespace:   System.Windows
Assembly:  WindowsBase (in WindowsBase.dll)

public static Rect Inflate(
	Rect rect,
	Size size
)

Parameters

rect
Type: System.Windows.Rect

The Rect structure to modify.

size
Type: System.Windows.Size

Specifies the amount to expand the rectangle. The Size structure's Width property specifies the amount to increase the rectangle's Left and Right properties. The Size structure's Height property specifies the amount to increase the rectangle's Top and Bottom properties.

Return Value

Type: System.Windows.Rect

The resulting rectangle.

Exception Condition
InvalidOperationException

rect is an Rect.Empty rectangle.

The Width of the resulting rectangle is increased by twice the Width of the specified Size structure, because both the left and right sides of the rectangle are inflated. Likewise, the Height of the resulting rectangle is increased by twice the Height of the specified Size structure.

The following example shows how to use the Inflate(Rect, Size) method to change the size of a rectangle.

private Size inflateExample3()
{
    // Initialize new rectangle.
    Rect myRectangle = new Rect();

    // The Location property specifies the coordinates of the upper left-hand 
    // corner of the rectangle. 
    myRectangle.Location = new Point(10, 5);

    // Set the Size property of the rectangle with a width of 200
    // and a height of 50.
    myRectangle.Size = new Size(200, 50);

    // Use the static Inflate method to return an expanded version of myRectangle1.   
    // The size of myRectangle2 is 240,110. Note: Width of the resulting rectangle is increased 
    // by twice the Width of the specified Size structure, because both the left and right 
    // sides of the rectangle are inflated. Likewise, the Height of the resulting 
    // rectangle is increased by twice the Height of the specified Size structure.
    Rect myRectangle2 = Rect.Inflate(myRectangle, new Size(20, 30));

    return myRectangle2.Size;

}
