The Snapscan backend currently treats the 1236S as if it is a 30bit
|
|
<BR>
|
|
scanner. The Afga site says its a 36bit scanner. In that case the error may
|
|
<BR>
|
|
be a simple one. In snapscan.c look for the section that sets the colour
|
|
<BR>
|
|
depth for the scanner (look for pd->depths = depths12). In that sections
|
|
<BR>
|
|
add the line "case SNAPSCAN1236S:" above the existing line "case
|
|
<BR>
|
|
PRISA620S:" and see what happens.
|
|

|
|
<P>Remember - this is just a guess!
