RecognizerGuide.Midline Property
Gets or sets the midline height. The midline height is the distance from the baseline to the midline, of the drawn box.
Namespace: Microsoft.Ink
Assembly: Microsoft.Ink (in Microsoft.Ink.dll)
Syntax
'Declaration
Public Property Midline As Integer
'Usage
Dim instance As RecognizerGuide
Dim value As Integer
value = instance.Midline
instance.Midline = value
public int Midline { get; set; }
public:
property int Midline {
int get ();
void set (int value);
}
public function get Midline () : int
public function set Midline (value : int)
Property Value
Type: System.Int32
The midline height of the guide in HIMETRIC units.
Remarks
The value is 0 if the midline is not present.
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;
}
