[Bug 525441] Re: Reduce memory usage


This issue is still not fixed on 3.14.0-ubuntu1. When scanning I see the
same behaviour as ametedinov describes in #8

  Reduce memory usage

Bug description:
  i just scanned a multipage document (something like 15 pages) using simple-scan. everything went like a charm and i really like the application and it's concept a lot! thanks so much, robert!
  and probably thanks to canonical, i think there is some money involved (?) :)

  however it used an impressive 750 MB of memory doing so! this was not
  actually a problem, but this clearly does not scale and for other
  hardware it would have been problematic already.

  i suppose all raw image data is kept in memory until the complete
  batch is finished, the file saved and closed, but i did not really
  investigate in detail.

  solution: memory usage should be optimized.

  best regards!
