Example

This example puts all the lines into their own paragraphs. It uses the lines from an InkAnalyzer, theInkAnalyzer; creates a new paragraph subnode for each of them; reparents the lines to those new paragraphs; and deletes the original paragraphs.

' Take each line and make it its own paragraph
Dim originalParagraphs As ContextNodeCollection = _
    theInkAnalyzer.FindNodesOfType(ContextNodeType.Paragraph)

Dim lines As ContextNodeCollection = _
    theInkAnalyzer.FindNodesOfType(ContextNodeType.Line)

For Each lineNode As ContextNode In lines
    ' Create a new paragraph
    Dim paragraph As ContextNode = lineNode.ParentNode
    Dim writingRegion As ContextNode = paragraph.ParentNode
    Dim newParagraph As ParagraphNode = CType(writingRegion.CreateSubNode(ContextNodeType.Paragraph), ParagraphNode)
    ' Reparent the line
    lineNode.Reparent(newParagraph)
Next lineNode

' Remove original paragraphs 
For Each originalParagraph As ContextNode In originalParagraphs
    Dim originalWritingRegion As ContextNode = originalParagraph.ParentNode
    originalWritingRegion.DeleteSubNode(originalParagraph)
Next originalParagraph

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