Значение свойства

The area that has changed since the last analysis operation.

Заметки

This property identifies the areas that need to be analyzed or reanalyzed. All of the InkAnalyzerBase methods that add, remove, or update stroke data also update the DirtyRegion property. To manually mark an area for reanalysis, use the DirtyRegion object's Union method.

The InkAnalyzerBase analyzes ink within its DirtyRegion during a call to Analyze or BackgroundAnalyze. However, the ink analyzer may expand the analysis operation to include neighboring regions.

This property may contain nonadjacent areas.

Примеры

This example performs ink analysis on an InkAnalyzerBase, theInkAnalyzerBase, if the analyzer's DirtyRegion is not empty.

' Only start ink analysis if the dirty region is not empty.
Dim theStatus As System.Windows.Ink.AnalysisCore.AnalysisStatusBase = Nothing
If Not theInkAnalyzerBase.DirtyRegion.IsEmpty Then

    ' Perform the ink analysis.
    theStatus = theInkAnalyzerBase.Analyze()

End If

// Only start ink analysis if the dirty region is not empty.
System.Windows.Ink.AnalysisCore.AnalysisStatusBase theStatus = null;
if (!theInkAnalyzerBase.DirtyRegion.IsEmpty)
{
    // Perform the ink analysis.
    theStatus = theInkAnalyzerBase.Analyze();
}
