Hi Rick,<br>
|
|||
|
|
<p>
|
|||
|
|
I think the only feature that can be done by hardware/firmware of the<br>
|
|||
|
|
scanner is color correction. But there is little support in the<br>
|
|||
|
|
hp-backend of SANE. Concerning color you can only select NTSC or RGB<br>
|
|||
|
|
colors and you can do some brightness/contrast/gamma corrections.<br>
|
|||
|
|
Snap-to-colors or vetorization of lineart is neither supported by the<br>
|
|||
|
|
firmware nor by the backend.<br>
|
|||
|
|
<p>
|
