Hi,

 
I'm developing an application that has to save the scan settings. I'm using SaveXmlParameters and LoadXmlParameters, it seems to work fine with capabilities like resolution and color, but it doesn't work with other capabilities like dropout color.

The scanner I'm using is a Panasonic KV-S2026C.

Any idea about this problem?

Thanks in advance
 

They may be using custom settings for that functionality but do not allow those settings to be saved/loaded through normal get/set operations. 

Try using the SaveParameters and LoadParameters methods instead.  With those methods the driver provides a block of data to save/load and it may include what you need.

Thanks for your answer Glenn,

 
but i still have the same problem, I'm not able to save some capabilities... like dropout color or dynamic threasholding.

 Has anyone the same problem?

 
Best Regards.
