Remarks
The exact definition of a paragraph is determined by the analyzing engines, but in general, a paragraph contains groups of lines that should reflow together.
A ParagraphNode object can contain any number of the following types of children:
LineNode objects.
InkBulletNode objects.
Example
The following example takes all of the LineNode objects in the ContextNode tree of an InkAnalyzer, theInkAnalyzer, and puts them in their own ParagraphNode objects.
' 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);
}
