We can just use a GTask to handle the detection while using the finish function to process the results to the image, so that it is more predictable when this happens and it does not depend on a thread returning. Also remove data duplication when possible, this class wasn't fully safe anyway to be used concurrently, so there's no point to copy data when not needed. Also added the hard constraint to not proceed with minutiae detection if something else is already doing this. At the same time we can mark the task to finish early on cancellation.
History
LibFPrint was originally developed as part of an academic project at the University Of Manchester.
It aimed to hide the differences between consumer fingerprint scanners and provide a single uniform API to application developers.
Goal
The ultimate goal of the FPrint project is to make fingerprint scanners widely and easily usable under common Linux environments.
