Hi Bhavin,the image you have sent to us has got too low resolution to be successfully read. Based on data you've sent us, we regenerated the high resolution image of the same barcode (available ).This high resolution image can be read with device that has got 480p video preview (Samsung Galaxy Ace). If a device does not support video preview of at least 640x480 resolution (preferably 1280x720), device will not be able to read such large barcodes.
In order to successfully read the PDF417 barcode, each dot in barcode must be at least 1.5 pixels large in image.Best regards,Nenad. Hello Bhavin,if I understood correctly you were able to scan the barcode and obtain a string that is written inside barcode? Our library just scans the barcode and returns its contents. The user of the library is responsible to interpret/decode the barcode data as they wish.Please note that we are currently preparing a parser for US driver's license PDF417 format and it should be available for purchase in the following months.
Our free non-commercial version of the library just returns the data that is contained inside the barcode - it does not perform any additional parsing logic on the data. For more information about our library, please visitBest regards,Nenad.
I guess it could be possible, but since PDF417 is a 2D Barcode, it's substantially different to the other types of barcode already implemented. The current code simply passes single scanlines to the decoding engine, which is not suitable for 2D blocks. I haven't done much research on PDF417 yet, but it states that it can be scanned with 1D scanners since it's just a stack of small 1D barcodes. I suppose alignment is one of the biggest issues to solve for this type of barcode.Any suggestions where to start?
The cut off between 76 and 77 is somewhat fuzzy, I've found Squarebacks with serial numbers in the 5300's and I've found MX II's with serial numbers in the 5300's which is how I come up with the mid 5300 range. I know there are a few that say they made Squarebacks in the first few months of 77 but there. Redline mx ii serial numbers. By Year/Model. Redline Squareback. First production bike was serial number 100. A low number bike would be early 1974. By the 500-600 range somewhere begin the 1975's. 1974-1975 Front gusset had no hole 1976-1977 Front gusset had two holes. 1978-1979 MX-II - 4130 frame/fork. Used the Squareback front.

In the meantime, I'll head over to zxing and take a look at their implementation (see ). This library is no longer maintained by the original author, it's now maintained by and me. Neither of us are barcode scanning experts, it's currently out of my reach to be able to introduce a scanner for a new type of barcode and I think the same is true of Eric?We do rely on community contributions for new scanners at this moment as we've been promoted to maintainership from the status of users interested in preserving the project and merging new community PRs.For that reason, I don't see this new scanner being on the roadmap anytime soon, but this got me thinking we could put up a call for participation to the README, what do you think,? Also if you would be willing to sponsor PDF417 scanner development through a bounty, that'd be helpful in attracting potential implementors.I'm going to keep this issue open, however the official status is that we don't plan on contributing support ourselves anytime soon. I have been successful in using a mixture of QuaggaJS and js-zxing-pdf417 but it's only a hack at this point. I have need to scan code 39 and code 128 but have also added the 'upcreader' decoder because I noticed that sometimes QuaggaJS incorrectly identifies a PDF417 as a upc and, in that instance, I pass the image/context on to the pdf417 processor and it works fine.

IF there were a plugin method for telling QuaggaJS how to correctly identify a given barcode based upon the symbology, it wouldn't have to actually do the decoding but just pass on to the plugin code.in this case not a 'plugin' per se but separate js-zxing-pdf417 library.
