I have some scanners which claimed to have “automatic color detection” feature.
As I know, TWAIN 2.1 support such feature. How can I:
1. know whether my scanner on hand support it (e.g. by getting capabilities like ICAP_AUTOMATICCOLORENABLED or something else)?
2. If my scanner support it, how can I enable it during scanning? Currently I set the ICAP_PIXELTYPE to BW (0), GRAY (1) or RGB (2) during scanning. Should the value be different for auto. color detection? Any other step is required?
Thanks a lot!
