BinarizergetBlackRow in class Binarizery - The row to fetch, which must be in [0, bitmap height)row - An optional preallocated array. If null or too small, it will be ignored.
If used, the Binarizer will call BitArray.clear(). Always use the returned object.NotFoundException - if row can't be binarizedpublic BitMatrix getBlackMatrix() throws NotFoundException
