Attempts to decode a sequence of ITF black/white lines into single digit. @param counters the counts of runs of observed black/white/black/... values

Encodes up to the first three bytes of array <var>threeBytes</var> and returns a four-byte array in Base64 notation. The actual number of significant

Sets number of layers and number of datablocks from parameter bits

Determines how closely a set of observed counts of runs of black/white values matches a given target pattern. This is reported as the ratio of the tot

Reads enough of the input stream to convert to/from Base64 and returns the next byte. @return next byte @since 1.3
