Article

Specifies the globally unique identifier (GUID) for getting the point array that represents the midline on an ink word.

Namespace: System.Windows.Ink
Assembly: IAWinFX (in IAWinFX.dll)

Syntax

'Declaration
Public Shared ReadOnly Midline As Guid
'Usage
Dim value As Guid 

value = PropertyGuidsForContextNodes.Midline

public static readonly Guid Midline

public:
static initonly Guid Midline

public static final var Midline : Guid

Remarks

The Midline field represents the midline on a ContextNode of type InkWord. A midline is the imaginary horizontal lines with which the top of the main body of each character, excluding extenders, is aligned. For example, the midline for the Latin letter "d" is the top of the circle.

Examples

The following example checks for an existing Midline in the ContainsPropertyData method of an AnalysisHintNode. If the Midline field exists, it is converted to a point array to populate myMidline.

' Get the line where the top of each character is aligned on an ink word 
If myAnalysisHintNode.ContainsPropertyData( _
   PropertyGuidsForContextNodes.Midline) Then 

    Dim myMidline As Integer() = _
        CType(myAnalysisHintNode.GetPropertyData( _
        PropertyGuidsForContextNodes.Midline), Integer())
End If

// Get the line where the top of each character is aligned on an ink word 
if (myAnalysisHintNode.ContainsPropertyData(
    PropertyGuidsForContextNodes.Midline))
{
    int[] myMidline =
        (int[])myAnalysisHintNode.GetPropertyData(
        PropertyGuidsForContextNodes.Midline);
}
