Hello Theo,

a little add-on to this topic.

Yesterday I measured the exact scanning times (in grey-scale mode, 8bit,
with 300 dpi). The threshold value for icreased time consumption is
between a scan width of 1150 and 1175 pixels.

A value above 1175 takes approx. 13 (thirteen!) times more time !!!
eg. window size 1150 x 200 = 5 sec
1175 x 200 = 65 sec !!

Scanning the whole A4 sheet this way would take more then 20 min.

Or am I doing something completely wrong ?
