[fprint] How to change image size?

[Daniel Montero]

Hello, I´m currently using the image_capture application from libfprint
to send the picture to a server that does the verifcation process and
then returns an answer. I've done some tests and it seems like
the scanned area of the images taken with libfprint are smaller than
the pictures taken in a Windows enviroment. If I use my thumbs, then it works fine, but if I use any
other finger it won't work (maybe the area is too small and not enough
minutias are extracted??). So I was wondering if it's posible to
increase the total area scanned, so more parameters can be extracted.
Thank you again...
