I've noticed that while scanning using openDIAS, the scanner can pause for half a second. Sometime this happens a dozen times over one page, which is rather annoying. So I've put some time aside to investigate and resolve the issue.
It turns out that the order that the scanner parameters are set, can have a significant affect on the performance of a scanning run - who knew? Anyway this issue is resolved, but....
While investigating the above, I've done some re factoring in the scanning modules which I think will make the addition of colour* scanning easier than I'd thought., so I'm going to have a bash at introducing the option of colour scans.
