Manual de control remoto universal urc11a. Hi,
We are integrate pdf417 in our project to scan US driving license but it is not scanning though it is in pdf417 format. any lead or should we purchase license for it ?

Thanks,
Bhavin

Hello Bhavin,
can you please tell us more about the conditions, device and barcode? Are lighting conditions good? Which device are you using? Is PDF417 barcode large (i.e. contains more than 10 columns). For scanning large barcodes, device with high quality camera is required (at least 720p, preferably 1080p video resolution).

Can you please send us the high resolution images/scans of barcode you are trying to scan so we can identify the problem.

Thank you for your report,
Nenad

Hi DoDoENT,

It is scanning successfully in iphone using same image and I am getting data like this:
https://gist.github.com/lanetteam-bhavin/9134757

Is anyway to decode this data ?

Thanks,
Bhavin.

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 here).

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

Hi Nenad,

I am able to scan with the barcode you regenerated.
And I got the data like this:
https://gist.github.com/lanetteam-bhavin/9134757

Is there any way to decode this data?

Thanks,
Bhavin

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 visit http://pdf417.mobi/

Best regards,
Nenad

Hello Nenad,

Thank you very much for your help and let me know once the parser is being available to purchase.

Best regards,
Bhavin

@DoDoENT can you explain how it is you regenerated the same barcode for @lanetteam-bhavin? Was it through any sort of image manipulation (sharpening, etc?)

@rmhrisk I used this barcode generator
