Remarks

The InkAnalyzer maintains a cache for all of the strokes associated with the InkAnalyzer. Changes to stroke data are not automatically reflected in the cache. When stroke information changes, such as when you move a stroke, call this method to clear the old stroke data.

Example

This example updates the dirty region of the InkAnalyzer, theInkAnalyzer, and clears the analyzer's cache in preparation for moving the StrokeCollection, selectedStrokes.

' Update the analyzer's dirty region to include the original
' bounding box of the strokes that are moving.
Me.theInkAnalyzer.DirtyRegion.Union(selectedStrokes.GetBounds())

' Clear the analyzer's cache for each stroke that is moving.
Dim theStroke As Stroke
For Each theStroke In selectedStrokes
    Me.theInkAnalyzer.ClearStrokeData(theStroke)
Next theStroke

// Update the analyzer's dirty region to include the original
// bounding box of the strokes that are moving.
this.theInkAnalyzer.DirtyRegion.Union(selectedStrokes.GetBounds());

// Clear the analyzer's cache for each stroke that is moving.
foreach (Stroke theStroke in selectedStrokes)
{
    this.theInkAnalyzer.ClearStrokeData(theStroke);
}
