Problems reading QR-Code

[cGiesen]

Hello,

I attached a PDF with 3 pages. On every page there is a QR-Code. In my application I create an image from avery page and ask for decode.

Page 1: the QR is not found, all other faound Page 2: all Barcode found, also the QR-Code witch is the same as on page 1 Page 3: here we find to QR codes. One ist found, the other not.

I habe really no idea, waths wrong.

Can I have some help please?

I use the example Source I found here in the readme

BTW: my handy is able to reade the codes ;) So i think, it's not a general error

Hello,

I play with my example and remove the space in front of the QR-Code on page 1. After that, the Code is found.

I think, thats not expected ;)

I don't know the code of the multiple barcode reader very well. But as far as I know it uses a very simple algorithm. I think in your case the space between two codes is too small. But I'm not sure.

Hello, I'm doing the same thing, but with no (detected) problems so far... Can you send the pdf sample to test?
