Camera scan datamatrix focus/area scan #570

Closed DigitalVanilla closed 1 year ago

DigitalVanilla commented 2 years ago

Howdy,

I have one question: I use the whole camera frame to scan around 30fps for a sequence of datamatrix codes as fast as possible, but I did notice that if the datamatrix is in the middle of the screen the decoder can "decode', but if the datamatrix (always in focus though) is slightly offset to the center of the screen, it does not works. If the code use the whole area given to scan for any code, why does it works only in the center of it and not like 10 pixels away from the right for example?

Thanks
