WritingRegionNode Class
Assembly: Microsoft.Ink.Analysis (in microsoft.ink.analysis.dll)
A writing region has a single reading order, such as top down.
Several writing regions can coexist in the same document on the same page if they have different orientations. For example, if a user writes notes that are primarily horizontal but then scribbles a few words diagonally in a corner, the diagonal words are considered to have a different orientation. A new WritingRegion is created for that diagonal text.
A WritingRegionNode object can contain the following types of child elements:
-
Any number of ParagraphNode objects.
-
Any number of nodes with an unknown Guid value.
For more information, see conceptual topic on WritingRegion and AlignmentLevel.
The following example takes a TextBox, selectedResultsTextBox, whose Text property has previously been set to the value returned by GetRecognizedString for a WritingRegionNode, writingRegion. The user has selected some text in the TextBox. The example code marks the Strokes that corresponds to that selection.
' Find out what's been selected in the text box Dim selectionStart As Integer = selectedResultsTextBox.SelectionStart Dim selectionLength As Integer = selectedResultsTextBox.SelectionLength ' Return if no text is selected. If selectionLength = 0 Then Return End If ' Get the nodes that correspond to that range Dim selectedRegionSubNodes As ContextNodeCollection = _ writingRegion.GetNodesFromTextRange(selectionStart, selectionLength) ' Use the new start and length value to update the ' selection in the TextBox selectedResultsTextBox.SelectionStart = selectionStart selectedResultsTextBox.SelectionLength = selectionLength ' First, set all strokes to black Dim inkStroke As Stroke For Each inkStroke In writingRegion.Strokes inkStroke.DrawingAttributes = New DrawingAttributes(Color.Black) Next inkStroke ' Next, set all selected sub nodes to red Dim node As ContextNode For Each node In selectedRegionSubNodes For Each inkStroke In node.Strokes inkStroke.DrawingAttributes = New DrawingAttributes(Color.Red) Next inkStroke Next node
