Ink.GetBoundingBox Method

Returns the bounding Rectangle Leave Site that contains all of the Stroke objects in the Ink object.

Definition

Visual Basic .NET Public Function GetBoundingBox() As Rectangle
C# public Rectangle GetBoundingBox();
Managed C++ public: Rectangle* GetBoundingBox();

Return Value

System.Drawing.Rectangle. Returns the Rectangle Leave Site that defines the bounding box of the Strokes collection in the Ink object.

Remarks

The bounding Rectangle Leave Site is in ink space coordinates.

When the bounding box is affected by the pen width, then this width is scaled appropriately for the Renderer object's view transform. To do this, the pen width is multiplied by the square root of the determinant of the view transform.

Note: If you have not set the pen width explicitly, it is 53 by default. You must multiply the pen width by the square root of the determinant to yield the correct bounding box. The height and width of the bounding box are expanded by half this amount in each direction. Consider an example in which the pen width is 53, the square root of the determinant is 50, and the bounding box is (0, 0, 1000, 1000). The pen width adjustment to the bounding box in each direction is calculated as (53 * 50) / 2, and the right and bottom sides are incremented by one. This results in a rendered bounding box of (-1325, -1325, 2326, 2326).

Note: The bounding Rectangle Leave Site that this method returns is a copy of the bounding box of the Strokes collection of the Ink object. Altering the Rectangle Leave Site that this method returns has no affect on the bounding box of the original Ink object.

Examples

[C#]

This C# example returns the bounding Rectangle Leave Site that contains the Strokes collection in an Ink object. The Ink object is associated with an InkCollector object, theInkCollector.

Rectangle theBoundingBox = theInkCollector.Ink.GetBoundingBox();

[Visual Basic .NET]

This Microsoft® Visual Basic® .NET example returns the bounding Rectangle Leave Site that contains the Strokes collection in an Ink object. The Ink object is associated with an InkCollector object, theInkCollector.

Dim theBoundingBox As Rectangle = _
    theInkCollector.Ink.GetBoundingBox()
