Feature #368 done

[juliansteenbakker]

First of all thank you for your contribution. I have checked it, however i think it would be best if we can leave the current implementation in place, and add this as an optional feature. Otherwise this would be quite a breaking change. I think the best would be to just leave the cutOutSize in place, and to either accept this, OR the separate scan area width and height.

What do you think about this?

[OrangeSofter]

At the moment, the constructor has a cutOutSize parameter, so backward compatibility is not broken.
It is assumed that either cutOutSize or cutOutWidth and cutOutHeight will be passed to the constructor, otherwise an exception is thrown
Are you saying you need to create a second constructor?

[juliansteenbakker]

My fault, i thought this removes all references to cutOutSize but it doesn't. Thanks !
