Algorithms behind 4-Scan

4-Scan uses 2 algorithms:

  1. 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.
  2. 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.
