How to generate .xyt file from image?

[aqt01]

Did this wrapper includes or has a way around to generate from image a xyt file?

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

libfprint supports the PGM format, maybe its possible to convert pgm to xyt ?
