The umax scanners don`t give back any addidtional bytes. But<br>
|
||
the scanarea is given in 1/1200 inch and the calculation of<br>
|
||
pixels form this does not always match the pixels the scanner<br>
|
||
sends back. This normally happens only if the resolution is greater than 600<br>
|
||
dpi.<br>
|
||
But it is not a rounding problem.<br>
