[Bug]: QR only returns invalid url notification

[vanwoods]

Describe the bug

1. Alfred returns 'invalid QR code' notification after making a screenshot. No matter which QR code. QR's have a valid url.
2. Universal action also not working correct returns file name of file.

Debugger output:

I'm posting a QR code here, could you try scanning it? Based on your description, I think you didn't scan a correct address QR code.

After scanning the QR code I sent, the correct address is https://github.com/alanhg/alfred-workflows/issues/375

Hi, thnx for the quick reply!

Your QR code works fine, however when shown reversed (see screenshot) it doesn't work. And returns invalid QR code.

Is it possible to make it work to QR code's that is shown reversed (or other color combinations)?

1. I have updated the workflow.
2. You need update workflow and have a try.
3. some step is required.
   • open the workflow configuration and check this.
   • install the new package.

I believe that not everyone needs this feature, so it should be configurable. If necessary, the corresponding dependencies can be installed.

Awesome, works like a charm now.

Thanks for fixing this!

Here I'll share the principle. The workflow depends on ZBar, which does not support color-inverted images. So I have no choice but to reverse the colors of the image and then try to read it again.

so I have to brew install imagemagick
