Exempel

I det följande exemplet visas hur du använder cache-hints-alternativet för en DrawingBrush.

DrawingBrush drawingBrush = new DrawingBrush();
            
// Set the caching hint option for the brush.
RenderOptions.SetCachingHint(drawingBrush, CachingHint.Cache);

// Set the minimum and maximum relative sizes for regenerating the tiled brush.
// The tiled brush will be regenerated and re-cached when its size is
// 0.5x or 2x of the current cached size.
RenderOptions.SetCacheInvalidationThresholdMinimum(drawingBrush, 0.5);
RenderOptions.SetCacheInvalidationThresholdMaximum(drawingBrush, 2.0);
Dim drawingBrush As New DrawingBrush()

' Set the caching hint option for the brush.
RenderOptions.SetCachingHint(drawingBrush, CachingHint.Cache)

' Set the minimum and maximum relative sizes for regenerating the tiled brush.
' The tiled brush will be regenerated and re-cached when its size is
' 0.5x or 2x of the current cached size.
RenderOptions.SetCacheInvalidationThresholdMinimum(drawingBrush, 0.5)
RenderOptions.SetCacheInvalidationThresholdMaximum(drawingBrush, 2.0)
