Rect::Offset Method (Rect, Double, Double)

 

Returns a rectangle that is offset from the specified rectangle by using the specified horizontal and vertical amounts.

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

public:
static Rect Offset(
	Rect rect,
	double offsetX,
	double offsetY
)

Parameters

rect
Type: System.Windows::Rect

The rectangle to move.

offsetX
Type: System::Double

The horizontal offset for the new rectangle.

offsetY
Type: System::Double

The vertical offset for the new rectangle.

Return Value

Type: System.Windows::Rect

The resulting rectangle.

Calling this method with an empty rectangle (Rect::Empty) is not allowed.

The following example shows how to use the Offset(Rect, Double, Double) method to change the position of a rectangle.

private Point offsetExample4()
{
    // 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);

    // Create a vector to use to offset the position of the rectangle.
    Vector vector1 = new Vector(20, 30);

    // The Offset method translates the specified rectangle by the specified horizontal 
    // and vertical amounts and returns the resulting Rect. 
    // resultRect location changed from 10,5 to 30,35.
    Rect resultRect = Rect.Offset(myRectangle, 20, 30);

    // This rectangle's location changed from 10,5 to 30,35.
    return resultRect.Location;
