Noticed your excellent barcode scanner does not recognise MaxiCode type
codes (used by UPS).

You're welcome to write support; there's nobody that can work on it
otherwise though.

I'm contributing some code for this. Here's a reader we developed to verify
our Maxicode generator (http://bfo.com/products/pdf) was correct. The code
is fairly rough but it does work, although there's no Reed Solomon
correction and it would clearly need adaptation to the zxing design, you're
welcome to it.

This is a first-shot implementation of MaxiCode support for zxing.

working:
- pure_barcode parsing
- reed solomon error correction
- decoding (modes 2 - 5, based on mike32767s code)

not yet implemented:
- detection
- parsing for skewed or rotated images

I would like to request commit rights, to commit and maintain MaxiCode
support. SVN diff is attached for review and comments. Thank you.

This is looking quite good, thanks. I can commit with a few small changes,
and give you commit access. I think that some of this won't be compatible
with J2ME, but, I think we're giving up on that. Also, is it possible to
use existing methods to find the top-left and bottom-right of a pure
barcode rather than a new method that finds all four?

... and just checking, what's the source of this code? Is any from a third-party source? I want to make sure any authors are OK with contributing this to the project under the Apache License.

Unfortunately, that is not the case. Top-left is often not leftmost, and
bottom-right is often not rightmost. Additionally, this way it also works
with slightly squished codes as long as they are not skewed or rotated
(like maxicode02.png - which I photographed and corrected the perspective
manually).

Alrighty. I'm not sure if my second reply came through here -- was wanting
to confirm that the code here is original work and OK to contribute to the
project. Looks like you built on work from the code posted earlier, which
is OK, and if you've just added your own original work, that's all set.

Yes, all set. The only code I used is the one posted by mike32767, the rest
is by me / based on code in zxing already.

I've committed a slightly changed version of your patch, mostly to make
style consistent. I will add you as a committer

I am trying to read maxicode on android but can't figure out how to use
mike's code that is if it is working. Any suggestions?

IIRC there is a decoder but no detector for Maxicode. You would have to
complete it by creating an implementation to find a Maxicode in an image.
Right now I think it works for pure synthetic images only.

find maxicode in an image using zxing?

Only if the image is synthetic -- that's what I was saying. There is no
detector for general camera images.

Has any one tried Maxicode reader on actual UPS barcode? It gives some
symbols at the end of the message that should be the weight and other
information e.g.

UPSN 220W90 07$FL:X-/,UY
JKY -M,R('3( P H6W )
0.SXI#Z%H(J

Has anyone been able to get ZXing to detect MaxiCode barcodes through the
camera? We are looking for an iOS library to scan MaxiCodes and this seems
like the closest to it.
