Help to change the area of Scan

[markolino85]

Hello,
i am an appasionate of Android programming.
I use this library and it's work fine, so in my code when i tap a button the scanner start :

IntentIntegrator integrator = new IntentIntegrator(this);
                integrator.setOrientationLocked(true);
                integrator.setPrompt("any strings");
                integrator.setCaptureActivity(ActivityCaptureCustom.class);
                integrator.initiateScan();

And of course i handle the result.
I've need to have the rectangle of scanner smaller, how to change it's height and width ?
Is it possible?
Thanks a lot
