Here is the code and output
import pyfprint
x = pyfprint.discover_devices()[0]
y=x.enroll_finger()

Output: swig/python detected a memory leak of type 'struct fp_print_data *', no destructor found.

I'm using pyfprint these days but I don't kown how to use the 'save_to_disk' method in pyfprint. I've already used 'save_to_file' method that saved an image. But I couldn't read the saved images, how could I get there ? Any help ?

Did this wrapper includes or has a way around to generate from image a xyt file?
https://github.com/freedesktop/libfprint/blob/master/libfprint/fpi-img.c#L313

I want to compare a single fingerprint minutiaei or file vs a database using bozorth3 algorithm. But i need to generate .xyt file in order to use the algorithm for comparing

https://www.nist.gov/services-resources/software/nist-biometric-image-software-nbis

Any help/suggestions?

Thanks in advance!

Hi there, I would like to incorporate your code into a project. For ease of deployment and portability, would it be possible to simply put the project into a folder and import it from there? I am familiar with Python, but I've never worked with Cython so I don't know where to start with this. I noticed there was an AUR package but unfortunately it is broken.

some segmentation fault onthe process of reading the fingerprint.
the same function using the C library doesn't gave me any errors.
