Заметки

The InkAnalyzer maintains a cache for all strokes associated with the InkAnalyzer. Changes to stroke data are not automatically reflected in the cache. If stroke information changes (for example, if you move a stroke), call this method to clear old stroke data.

Примеры

This example updates the dirty region of the InkAnalyzer, named theInkAnalyzer, and clears the analyzer's cache while preparing to move the StrokeCollection, named 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);
}
