示例
此示例更新 InkAnalyzer (theInkAnalyzer) 的已更新区域，并在准备移动笔画集合 selectedStrokes 的过程中清除该分析器的缓存。
' Update the analyzer's dirty region to include the original
' bounding box of the strokes that are moving.
Me.theInkAnalyzer.DirtyRegion.Union(Me.selectedStrokes.GetBoundingBox())
' Clear the analyzer's cache for each stroke that is moving.
Dim theStroke As Microsoft.Ink.Stroke
For Each theStroke In Me.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(
this.selectedStrokes.GetBoundingBox());
// Clear the analyzer's cache for each stroke that is moving.
foreach (Microsoft.Ink.Stroke theStroke in this.selectedStrokes)
{
this.theInkAnalyzer.ClearStrokeData(theStroke);
}
