Ejemplos

En este ejemplo todas las líneas se sitúan en sus propios párrafos. Se utilizan las líneas de un objeto InkAnalyzer, theInkAnalyzer; se crea un nuevo subnodo de párrafo para cada uno de ellos; se cambia el elemento primario de las líneas para esos nuevos párrafos y se eliminan los párrafos originales.

' Take each line and make it its own paragraph
Dim originalParagraphs As ContextNodeCollection = _
    theInkAnalyzer.FindNodesOfType(Microsoft.Ink.ContextNodeType.Paragraph)
Dim lines As ContextNodeCollection = _
    theInkAnalyzer.FindNodesOfType(Microsoft.Ink.ContextNodeType.Line)
Dim lineNode As ContextNode
For Each lineNode In lines
    ' Create a new alignment level and paragraph
    Dim lineParagraph As ContextNode = lineNode.ParentNode
    Dim writingRegion As ContextNode = lineParagraph.ParentNode
    Dim newParagraph As ParagraphNode = _
        CType(writingRegion.CreateSubNode(Microsoft.Ink.ContextNodeType.Paragraph), ParagraphNode)
    ' Reparent the line
    lineNode.Reparent(newParagraph)
Next lineNode
' Remove original paragraphs and alignment nodes
Dim originalParagraph As ContextNode
For Each originalParagraph In originalParagraphs
    Dim originalAlignmentLevel As ContextNode = originalParagraph.ParentNode
    originalAlignmentLevel.DeleteSubNode(originalParagraph)
    originalAlignmentLevel.ParentNode.DeleteSubNode(originalAlignmentLevel)
Next originalParagraph

            // Take each line and make it its own paragraph
            ContextNodeCollection originalParagraphs = 
                theInkAnalyzer.FindNodesOfType(Microsoft.Ink.ContextNodeType.Paragraph);
            ContextNodeCollection lines = 
                theInkAnalyzer.FindNodesOfType(Microsoft.Ink.ContextNodeType.Line);
            foreach (ContextNode lineNode in lines)
            {
                // Create a new paragraph
                ContextNode paragraph = lineNode.ParentNode;
                ContextNode writingRegion = paragraph.ParentNode;
                ParagraphNode newParagraph = (ParagraphNode)
                    writingRegion.CreateSubNode(Microsoft.Ink.ContextNodeType.Paragraph);
                // Reparent the line
                lineNode.Reparent(newParagraph);
            }
            // Remove original paragraphs 
            foreach (ContextNode originalParagraph in originalParagraphs)
            {
                ContextNode originalWritingRegion = originalParagraph.ParentNode;
                originalWritingRegion.DeleteSubNode(originalParagraph);
            }
