This takes an array holding the values of the PDF 417 @param input a byte array of information with 0 is black, and 1 is white @return BitMatrix of t

Computes the start and end of a region of pixels, either horizontally or vertically, that could be part of a Data Matrix barcode. @param fixedDimensi

<p>Estimates module size based on two finder patterns -- it uses {@link #sizeOfBlackWhiteBlackRunBothWays(int, int, int, int)} to figure the width of

Given a count of black/white/black pixels just seen and an end position, figures the location of the center of this black/white/black run.

Computes the UPC/EAN checksum on a string of digits, and reports whether the checksum is correct or not. @param s string of digits to check @return t

Combines this object's current estimate of a finder pattern position and module size with a new estimate. It returns a new {@code FinderPattern} conta

Expands a UPC-E value back into its full, equivalent UPC-A code value. @param upce UPC-E code as string of digits @return equivalent UPC-A code as st

Because we scan horizontally to detect the start and stop patterns, the vertical component of the codeword coordinates will be slightly wrong if there

<p>Decodes given set of received codewords, which include both data and error-correction codewords. Really, this means it uses Reed-Solomon to detect

Attempts to decode a single UPC/EAN-encoded digit. @param row row of black/white values to decode @param counters the counts of runs of observed blac

We're going to examine rows from the middle outward, searching alternately above and below the middle, and farther out each time. rowStep is the numbe

@return 2 to the power of a in GF(size)

Method added by PHIL. [Thanks, PHIL. -Rob] This pads the buffer without closing the stream. @throws java.io.IOException if there's an error.

@return birthday formatted as yyyyMMdd (e.g. 19780917)

Converts the message to a byte array using the default encoding (cp437) as defined by the specification @param msg the message @return the byte array

Translate the symbol into a codeword. @param symbol @return the codeword corresponding to the symbol.
