Is 400x240 a hardware limitation? Or would it be possible to use e.g. 800x480?

Besides, I'm eagerly waiting for python plugins!
Which device are you running on?

I just tried the link you gave and other than needing to hold the N900 quite a long way back (as the barcode that was displayed was rather large on my monitor) it all seemed to work fine.

I did a rough count, and the barcode I scanned was only something like 60x60 elements (probably 64, though I've not checked the QR spec recently to see what the required sizes are), which should be easy to decode.

Also, iirc internally mBarcode uses a frame size of 640x480 on the N900 and this size of frame should also be saved in the history list/exported to file (though if it's not, please let me know and I'll check). The thumbnail that is actually presented to the user is smaller afaicr.


I'll try to get PythonQT packaged up this evening when I have a few minutes spare
