jquery - pdf417 Javascript Reading / Decoding -

I have been added to decoding / reading PDF 417 (Driving License) for a web based application.

Input: Image of driving license. (400-600 dpi)

Processing: PDF 417 Detecting / analyzing data

Output: Pardes PDF 417 data.

Limitations: Its a web based app: Running through IE, Chrome, Safari. I can not install anything on the local machine

So I am checking for a few days and I have not found a good way to do this work. Ideally, the entire decoding will be on the client machine using Javascript / junkie. However I have not got any script / library that can do this. I've found that only the other option was probably a Java servlet or a php extension; Both of which are not ideal because upload time is going to push me on the allocation of my time

Does anyone have a Javascript or JQuery library that can handle it?

Or maybe there is a better way of incorporating this functionality which I am not seeing?

My contribution is two times. First of all (good news!) I'm 100% sure you want to get CVATat using Javascript. Chrome / Firefox is probably OK but it is Safari (6+) and IE (IE10 +). Source:

Secondly, I hope my contribution to solve this problem is very far away, though I believe that I have not come with the PDF 417 image reading algorithm which will be the last part of the puzzle .

OK, we go here: a) Javascript (running on client machines) to present a GUI user to file them from your local file system Allows to choose (one image of your driving license) and then ... b) Bring it into the Javascript app (without including all servers or java); And ... C) ... Javascript, it interprets the dark / light pattern of pars and PDF 417 barcodes in which it extrapolates encoded 'siltext' human-readable data. I have not said Java as an alternative to the Java applet, it seems that the permission to run in Chrome will never be allowed, though Java has a good image data handling package that has been sorted properly.

Understanding and A) code is required

HTML forms allow the programmer to use the file upload field for many years. You'll need:

  & lt; Input type = "file" id = "myFileInput" & gt;  

Understanding and code required for B

Additionally, JavaScript will require the use of (most important) in favor of those things HTML5 Flimmer API (View) ... Viz-A-Vis:

  var Reader = New File Reader (); // ... and ... reader.readAsDataURL (file);   
 Where  readAsDataURL ()  is giving you base64-encode binary data that is going to work for you when it comes to slotting in  < Code> var ing = new image (); Example of an image instantiated with  i.e.  src  to  data: image / gif; You can at least display a driver's license in your webpage, with base64, * data *  set. Later I put a new image in the dom as the option to carry this new instant image and describe it as the alternative to display through the 2D reference of canvas, but we come in a minute. All the discussions I have ever discussed can be seen in an action on all blogs. TeamTreehouse.com's Code Pen Demo () Also, for a more start-up friendly talk-through,  FileReader ()  you want to watch this video (), but be patient, as you can about image uploads In and 5mins30secs only mentioned in the performance has been mentioned. / P>

 This is where I came without flak because I did not really manage to find you right after Done, but I found out the UPC format barcode: (demo =). I'm not sure, but I think the data has been filled with data from  new image ()  (once sent to  src ) to get this toobe  FileReader ()  API) and use it on a canvas 2D reference. This proves that this can be done, but to write the algorithm, to understand how to explain the data, PDF417 should understand: I have found these links as useful starting locations 
 
 
 
 
 
 Good luck!
