Almost there...
The image resolution on Windows is known and the byte array gathered is
double of widthxheight indicating it's a 16 bit grayscale image and the
following way to build image using Pillow almost works - as in the shape
of the x rayed finger is fine.
Image.frombytes('L',(1168,1562),buf,'raw','L;16B',0,1)
Only problem left if I save it back as a raw bitmap (just to see how much
size a lossless format gives) it is of half the number of bytes gathered
from which it seems it's not using full 16 bit range. The X ray quality in
turn is affected.
How to make Pillow consume all 16 bits per pixel is unclear. Whether L;16B
is right or not I am unsure.
