Yes, just put the SANE_FRAME_RGBI in sane.h and hope it<br>
|
||
will be made official later on..<br>
|
||
<p>
|
||
When I suggested this some time ago someone replied that that the RGBI<br>
|
||
term was already used in the videoworld and that this might lead to <br>
|
||
confusion. However, when doing a websearch on RGBI it does not appear<br>
|
||
to be used extensively for that (most hits where for old Commodore<br>
|
||
monitors). So in the context of scanners/imaging devices it shouldn't<br>
|
||
be too confusive.<br>

That would be a good idea if you want to batch scan hundreds of<br>
|
||
slides. But probably most people would like to get just one or a few<br>
|
||
images as quickly as possible into the Gimp. For that it would <br>
|
||
be nessacary to include the dust removal code also into the backend.<br>
