Article
2012-10-19

Gets or sets the invisible writing area of the recognition guide in which writing can actually take place.

Namespace: Microsoft.Ink
Assembly: Microsoft.Ink (in Microsoft.Ink.dll)

Syntax

'Declaration
Public Property WritingBox As Rectangle
'Usage
Dim instance As RecognizerGuide 
Dim value As Rectangle 

value = instance.WritingBox

instance.WritingBox = value

public Rectangle WritingBox { get; set; }

public:
property Rectangle WritingBox {
    Rectangle get ();
    void set (Rectangle value);
}

public function get WritingBox () : Rectangle 
public function set WritingBox (value : Rectangle)

Property Value

Type: System.Drawing.Rectangle
The rectangular writing area of the guide box, in ink space coordinates.

Remarks

The writing box provides a margin of error to users who write outside the drawn box – the lines that are physically drawn on the tablet's screen within which users write. Use the DrawnBox property to set the drawn box.

Examples

In this example, a RecognizerContext object is instantiated, and the Guide property assigned by creating a new RecognizerGuide object.

' create a new RecognizerContext object
mRecognizerContext = New RecognizerContext()
' if the Recognizer supports LinedInput, set the Guide 
If (mRecognizerContext.Recognizer.Capabilities And RecognizerCapabilities.LinedInput) <> 0 Then 
    ' get the lower right corner in pixel units 
    Dim lowerRight As Point = New Point(mInkOverlay.AttachedControl.Width, mInkOverlay.AttachedControl.Height)
    ' convert to ink space units
    mInkOverlay.Renderer.PixelToInkSpace(Me.CreateGraphics(), lowerRight)
    ' create Rectangles 
    Dim writingBox As Rectangle = New Rectangle(0, 0, lowerRight.X, lowerRight.Y)
    Dim drawnBox As Rectangle = New Rectangle(0, 0, lowerRight.X, lowerRight.Y)
    ' shrink drawn box relative to writing box
    drawnBox.Inflate(-100, -100)
    ' create Guide with 8 rows, zero columns, and no midline 
    Dim guide As RecognizerGuide = New RecognizerGuide(8, 0, 0, writingBox, drawnBox)
    mRecognizerContext.Guide = guide
End If

// create a new RecognizerContext object
mRecognizerContext = new RecognizerContext();
// if the Recognizer supports LinedInput, set the Guide 
if ((mRecognizerContext.Recognizer.Capabilities & RecognizerCapabilities.LinedInput) != 0)
{
    // get the lower right corner in pixel units
    Point lowerRight = new Point(mInkOverlay.AttachedControl.Width, mInkOverlay.AttachedControl.Height);
    // convert to ink space units
    mInkOverlay.Renderer.PixelToInkSpace(this.CreateGraphics(), ref lowerRight);
    // create Rectangles
    Rectangle writingBox = new Rectangle(0, 0, lowerRight.X, lowerRight.Y);
    Rectangle drawnBox = new Rectangle(0, 0, lowerRight.X, lowerRight.Y);
    // shrink drawn box relative to writing box
    drawnBox.Inflate(-100, -100);
    // create Guide with 8 rows, zero columns, and no midline
    RecognizerGuide guide = new RecognizerGuide(8, 0, 0, writingBox, drawnBox);
    mRecognizerContext.Guide = guide;
}
