Specify the range of elongation values for judging the found region as a flaw. Elongation is calculated by dividing the length by the width, and represents how slender the found flaw is. The longer the flaw is, the larger the value becomes. The default values are 1.0 for minimum and 800.0 for maximum, and the specifiable value range is from 1.0 to 50000.0.
