peculiarventures / js-zxing-pdf417 Goto Github PK

Thanks for this fabulous port. Facing an issue though. Scanning the same card by clicking different images from the webcam gives different results each time. Is there a way we can do more rigorous/strict scanning for the valid barcode values?

When I access the example demo http://peculiarventures.github.io/js-zxing-pdf417/examples/zxing-pdf417-example1.html with mobile, it can't recongnize the barcode(I use the driver license card).
But it works if I upload the same picture with accessing by PC.

Hi,
It doesn't seem to scan rotated images.

Hi, I tried to decode both with mobile camera and laptop with file load. It doesnt seem to detect any pdf147 scan and returning empty Array. Implemented it same as example on github :( Please help.
`try {
console.log('trying to decode...');
source = new ZXing.BitmapLuminanceSource(ctx, img);

                  binarizer = new ZXing.Common.HybridBinarizer(source);
                  
                  bitmap = new ZXing.BinaryBitmap(binarizer);
                  
                  var decodingString = JSON.stringify(ZXing.PDF417.PDF417Reader.decode(bitmap, null, false),null,4);
                  console.log('return JSON value '+decodingString);
              } catch (err)
              {
                        console.log('Error in decoding...');
              }`

Do you have a CDN or package npm for this pdf417 barcode scanner?

This is working great with Excellent Quality Images. I am facing the Issues when I try to recognize the Barcode through Camera(Low Resolution). I came to know that the Problem is with Binarizing the low quality Images. You have any suggestions on Improving the Binarization to recognize the barcodes on low quality Images.
are you planning to work on this Improvisation.
let me know if you aware of any open sources to solve this Issue.

there is a recomended resolution or anything?

I am having problems decoding a PDF 417, others work perfect but this gives me the following error:
"ResultMetadata": { "ERROR_CORRECTION_LEVEL": "5", "PDF417_EXTRA_METADATA": { "SegmentIndex": 0, "FileId": null, "OptionalData": null, "IsLastSegment": false } },

Hi
Is there any plan to publish this library to npm?

Hi,
Is this possible?

Hi! I'm developing an interpreter for the PDF417 code from argentinian IDs. I've try this library, but none seems to work. Could it be something about colour? Size? The pictures are FullHD, scanned... Is there a way to force the "TRY HARDER" mode when invoking the decoder? Thnaks!

Hi,

I have barcode that don't seem to decode, I tried to figure out what the issue is and think its the start pattern that is not correct. There few other sites that is able to decode the barcode, so I know it can be done and I also know the barcode is not 100% according to specs.

Possible you can look at the barcode or maybe give me hint on how I can troubleshoot why start pattern not recognized.. I attach sample

Hello,

when "width" is applied to an image, recognition stops working, that is because display height and width is used instead of natural.

I am very much interested in this project. Could you guys please include a sample test page that shows how to call the correct pdf417 reader method with image as an input. Thanks
