Request: save vector formats (SVG, EPS) in QtQr

[Se Li]

It seems that QtQr can only save PNG files. It would be great if a vector format could be created as well.

Hi,

You should be able to save in SVG, in the save dialog change the format
filter and add the svg extension to the file name

QtQR (and qr-tools) support all the same formats as qrencode. We had a bug in the supported formats detection but you could specify the extension manually in the save dialog.

I've just pushed a fix, the save dialog should now show you all the supported formats and let you choose. It may take some time for the revision 48 to be built and available in the daily PPA.

I am on Arch and have just made and tested an adapted version of https://archlinux.org/packages/extra/any/qtqr/ using revision 48. The formats are all there in the format chooser. Thanks! One thing that is not working well though is the choice of a default extension (and thus format). If I set the format chooser to SVG and enter “test“ as a filename and then save, I am informed that a file “test.png” has been created. A check confirms that it is not a misnamed SVG file. That seems counterintuitive to me. The responsible code starts at line 639 in qtqr.py I think, but I don’t know how to get the status of the format chooser in order to choose the default extension better – or how to submit change suggestions here. So, no contribution from me for now beyond this nitpicking, sorry :-)

Thanks for the tip! I've noticed it too testing the fix, it's a little
weird how we handle the format detection and the default extension. I have
a workaround but I wanted to investigate it a little further and didn't
include it with the previous fix.

Thanks again for your help

Have a nice weekend!

I've just pushed a workaround to the file extension detection. I think it is acceptable until we fix the underlying problem in qrtools, it will be a breaking change.
