Issue with CODE128 BARCODE about node-dv HOT 3 CLOSED

This barcode can be read using ZXing for Android (Java). Unfortunately the zxing-cpp maintainer stepped down in mid 2013, so zxing-cpp got deprecated. The cause is likely to be:

• A difference between Code128Reader.java and Code128Reader.cpp
• ZXing's HybridBinarizer.cpp breaking the barcode

You should start by debugging this using the zxing-cpp command line interface. After this compare files (1.) line-by-line - its really easy as the port maps stunningly well. ZXing works internally more or less like this:

1. read a greyscale image
2. binarize the pixels adaptively using magical, but fast heuristics
3. (for 1D barcodes) scan the binarized matrix from mid outwards until a barcode can be decoded

Adding zBar to node-dv has already failed once (its written in C99, which ain't supported by MSVC) and its internals are a lot less clean than ZXing's.

I have checked HybridBinarizer and Code128Reader... the real differences are only:
on line 162 of Code128Reader.cpp

  {2, 1, 1, 2, 3, 2}, /* 105 */
  {2, 3, 3, 1, 1, 1}

vs

  {2, 1, 1, 2, 3, 2}, /* 105 */
  {2, 3, 3, 1, 1, 1,2}

see ZXingOBJc

I have patched and tried but same result... nothing of good
