I am writing a java program for fingerprint recognition, and I insert the fingerprint image in the MySQL database( in a field blob), but now is the problem. How do I go back to the image of the fingerprint? where I have to print it?( I presume in a canvas). help me please is very important, thanks to all.

The blob is a array of bytes, so is the Image.

So

img -> read bytes -> store as blob

vs

blob -> read bytes -> store as img
