I will improve Scan QR function in later version

[Sneezry]

jsqrcode works well at most of time, however, it fails in decoding sometimes. I will improve the lib in later version.

Maybe we need some computer vision knowledge.

I have solved LazarSoft/jsqrcode#41, however, I still need more images to test. Please post any qr code we fail to decode.

I have several codes that AWS produces that can't be scanned.

[bkalar09]

Another that wont scan.

Hi @bkalar09

Which version extension do you use? I can scan both of them with version 4.13

[bkalar09]

4.13

[Sneezry]

Strange :-S

I have tested several times, and it works all the time~

[bkalar09]

I'm working on a screen shot of it in action

[Sneezry]

I guess I know what the problem is... Is your display a retina one or do you zoom in or out your browser?

[bkalar09]

Here it is.

[bkalar09]

I am using a ThinkVision Pro 2840m. I don't zoom either.

[bkalar09]

My chrome version is Version "42.0.2311.135 m". The window I am using is "pinned" to the right side of the monitor. I am only using half of the screen for this instance of chrome.

[bkalar09]

My resolution is 3840 x 2160.

[Sneezry]

OK, I think I know how to solve your issue, we fail to locate the qr code under some retina displays.

I'm working on this now, please wait for a moment before I solve this :-)

Thanks for your feedback

[Sneezry]

@bkalar09 version 4.14 now is available in web store, please update your extension and feedback further, thanks :-)

@Sneezry For some reason it's not updating for me yet, however I am having the same problem with 4.13 if I scan twice. It works the first time but not the second time it doesn't scan correctly. It doesn't even draw the box on the screen when I drag the mouse.

[bkalar09]

That worked. Thanks

[multiwebinc]

It finally updated for me, but I still have the same problem.

Here's a screencast of what I mean: http://youtu.be/qvz8_n16Qas

I don't know how to make the resolution higher on Youtube, sorry for the bad quality.

Here's the original file (2MB) in case you want it: http://www.filedropper.com/out-1

@multiwebinc I watched the video, and I understand the problem you meet.

I think that is another issue about mouse event listening, I have created a new issue(#14) to track it.

Scan QR works fine now.
