Заметки
The writing box provides a margin of error to users who write outside the drawn box. Use the DrawnBoxTop, DrawnBoxLeft, DrawnBoxBottom, and DrawnBoxRight properties to set the drawn box.
The WritingBoxLeft property throws an ArgumentOutOfRangeException if you try to set it to a value less that AnalysisRegion.MinXY or greater than AnalysisRegion.MaxXY.
