Значение свойства

Тип: System.Int32
The number of rows in the guide box.

Заметки

Row height is determined by the size of the drawn box. To get or set the drawn box, use the DrawnBox property.

Use the values of the Columns and Rows properties to control the kind of recognition input that you use. When the Columns and Rows properties are both greater than zero, boxed input is used. The following table lists potential input modes and which values to set the Columns and Rows properties for each mode.

For this type of input	Set the Rows property to	And set the Columns property to
Free input	0	0
Vertical Lined input with 1 line	0	1
Vertical Lined input with n lines	0	n
Horizontal Lined input with 1 line	1	0
Horizontal Lined input with n lines	n	0
Boxed input with 1 box	1	1
Boxed input with 1 column of n boxes	1	n
Boxed input in a grid of boxes x rows by z columns	x	z

Примеры

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;
}
