if (cachingHint == CachingHint.Cache)
{
    // Get the minimum and maximum relative sizes for regenerating the tiled brush.
    double minimum = RenderOptions.GetCacheInvalidationThresholdMinimum(drawingBrush);
    double maximum = RenderOptions.GetCacheInvalidationThresholdMaximum(drawingBrush);

    // Perform action based on cache values...
}

' Get the caching hint option for the brush.
Dim cachingHintOpt As CachingHint = RenderOptions.GetCachingHint(drawingBrush)
