4-Scan uses 2 algorithms:
- In the mode „simple“ Potrace(TM) is active.
Potrace is a project developed by Peter Seliger.
This algorithm is fast and perfect for most images.
It does not trace multi-colored images and it does not provide a centerline mode.
- the „enhanced“ mode of 4-Scan uses Autotrace.
Autotrace developed by Martin Weber.
It uses more parameters to trace images in bad quality.
Multi-colored images are supported and a centerline mode is integrated.
Both alorithms support 64 bit processors.
