Problem with big images
Opened this issue · 7 comments
Hi,
I have the following problem:
If I scan a big images the browser (Mobile Safari )will crash. Desktop Browser like the latest Firefox runs often into a Timeout exception.
Do you know any best practice to avoid this error? Otherwise, I will try to shrink the picture before it will be parsed by your QR Code scanner.
The code works pretty fine for smaller images.
Image info:
Image 1: 1,8MB, 3264_2448 // error
Image 2: 1,67 MB 2592_1935 // error
Thanks!

Tobi, did you get past this? I just started with the code this evening and this is the last step before it's fully functional for me.
Any help is appreciated.
Hi,
long time no see. :). This was a limitation of iPhone 3GS and below. It works quite fine with iPhone 4S and later or Samsung Galaxy S3 and later.
Thanks for your reply.
Interesting because it crashes my mobile Safari on my iPhone 4S. Any thoughts as to why it wouldn't work for me?

Hi,
Works like a charm when selecting a small QR code from the pict library... But I can't make it work with a picture of a QR code taken directly with my iphone... Either safari crashes, either I got a "error decoding QR Code" message...
How did you solve it?
Anyone has a code snippet to share maybe? :D
Same thing happens to me. Big == breaks.

I've also seen this. Related?
Looks like I have the same problem here.
I can decode QR codes as long as the string encoded is not longer than 300-some characters.
For longer strings I get an error (on my implementation) and an "error decoding QR code" in the web.
For example, working QR of a string 300 characters long:
and the qr of a sightly longer string:
