Hi @bastianraschke, Is it possible to download the saved image without scanning my finger? for example, if I have the position and the characteristics of saved fingerprint, can I download the image with those 2 data?

Cheers

update: I tried to download the saved fingerprint image but the result image is so different if I download image while scanning my finger (based on the download_image.py example file) I can see my fingerprint clearly. Any idea?

Thank you,

Hi, this is expected because you may never put the finger at the same position on the sensor. Kind regards
