[sane-devel] snapscan & interpolation

  I have a snapscan 310, which has an optical resolution at 300dpi. Thus the xsane button only proposes resolution up to 300dpi.
But I know that with a good interpolation, one can scan with this scanner up to 1200dpi. 
Does anybody know how interpolation works?
Is it a job done by the scanner itself, or a soft post-prossessing that can be done with gimp?
Any comment welcome !
