Finger almost never match
I'm using ubuntu 20.04 laptop and bought a external fingerprint reader identified as
ELAN:Fingerprint ID 04f3:0c3d。It's in the support list. I build and install the 1.94.2 version libfprint.
fprintd-enroll works fine, but
fprintd-verify almost results in 'verify-no-match'. I use
builddir/examples for test, they generate enrolled.pgm and verify.pgm. I checks the 2 image , I think they are flip 180 degrees。Is that right？
Thanks for any help!
