|Thrown if the value is less than 0 or greater than 100.|
Given the random nature of the coverage, low values result in must faster performance than 100% coverage with generally the same results. A default value of 8 was derived after tests with many images. This results in accurate skew angle detection with fast speed. This property is exposed for edge cases where 8 is not sufficient. When accuracy is of utmost importance at the expense of speed, set this value to 100.
