I'm using the precompiled zbarimg.exe to batch decode QR codes. It's working great - thanks! I'm wondering if the process could be spead up by setting the config values to QR only? I'm unsure of the CLI syntax to do this.
I'm currently using:
zbarimg.exe -q myqr.png
What would the command look like to force QR only decoding? Would it speed the process up by much?
Thanks in advance!

You may experience some speedup by disabling unused symbologies. In general it is recommended practice (by the barcode specifications) to do so anyway.

Following the example in the manual, you enable specific symbologies by first disabling everything then re-enabling the target symbologies:
zbarimg -q -Sdis -Sqr.en myqr.png

That depends largely on the specific images you are trying to decode. In a quick test with the couple hundred images in our QR regression, I measure about 16% faster.
