pkoretic / pdf417-generator Goto Github PK

Hi there,

Our app is trying to encode the following delimited string in a barcode using the pdf417 generator and it contains a lot of accents for french words. The issue is that if there is an accent in between two repeated data items.
The generator may potentially be adding extra fields / repeating data when we are decoding it. Please see below examples.

Can you please assist with troubleshooting the issue? We have narrowed it down to when any word with an accent is in the middle of two repeated fields.

Original input string passed to the pdf 417 generator

|anything|É|anything|

Decoding the generated barcode:

|anything||anything|É|anything|

This is breaking our app because the barcodes are giving wrong data / extra data when accents is present.

Attaching the barcode generated

Thank you in advance!

Can you please publish the latest changes?

Hi, I need the fix here, #5

When I do npm install pdf417-generator@latest i get version 1.0.2

Our project is using
"pdf417-generator": "^1.0.2",

And we are facing the bc-multiply error for special chars such as Chloè

Thanks!

Hi @pkoretic in some cases we get an error
bc_multiply is not a function.

stack trace:

ERROR TypeError: r.bc_multiply is not a function

Do you have any idea what would cause the problem?

Kind regards,
Ivan

I think this is actually an issue with wkhtmltopdf, but I though you may have advice. The barcode renders fine in a normal browser, but when using wkhtmltopdf it's just blank. Any ideas?

Hi @pkoretic,

library is great, but in our case when it is used with angular application
installed like npm package, and strict mode declared we have problem
with this two variables which are not declared.

sequence = this.getInputSequences(code);
codewords = []; // array of code-words

can you add var statement before them?

Thanks!

Kind regards,
Ivan

I can see the the file locally, so it doesn't make sense to me that it's complaining about not see this file in the path listed: node_modules/pdf417-generator/lib/bcmath.js.

Can you confirm that this should work?

I'm not sure why these dependencies are not being recognized since they are part of the NPM package itself. I wouldn't think I would need to use CDN references if I have the NPM package installed. Further, the build tool seems to think it should be accessible as well. It might just be how I have the build script set up, but I would like to make sure that my expectations are right.

λ npm run build

When I attempt to create a PDF-417 barcode with a string containing more than 2000 characters, I do not receive anything back.

I have also opened an issue for the pdf417.js package.

I want the barcode bigger. Is there any way to setup it's size?
