QR code in pdf

[Ashu Sindhu]

I am using IText to generate pdf. For my japanese client, I need to put QR code on the PDF.

Does anyone have worked on QR code. Can they suggest any java library which I can use to creat QR code.

I am using Servlet.

Thanks in anticipation,
Ashu Sindhu

What is a "QR code"? Is it a specific Japanese encoding?

"QR code" is some kind of barcode. Here's a link to an article that says one of iText's rivals supports it:

QR code can be said an extension for barcode. While the barcode use much more space for less number of character and does not support UTF chars like kanji or kana, the QR code support kanji,kana and takes much less space.

My application is already using IText. And we can not change Itext library now. I was wondering if there is any java library which will give me QR code as an image which I can put on PDF using Itext.

Another thing I want to ask is if that image is sufficient for reading it using QR hardware ?

Thanks,
