Commented by mlmcl on 2015-10-17 17:20 UTC This is a little vague. If you're using the twaincsscan app, then you'll probably be best off using the driver UI built into the vendor's TWAIN driver. If it supports DAT_CUSTOMDSDATA, then you can save snapshots of your changes, and use those when you want to scan.

If you're looking to program with TWAIN CS, then I recommend running the twaincstst app. Once you've opened the driver you want to use, try selecting DG_CONTROL / DAT_CAPABILITY / MSG_GETCURRENT for ICAP_XRESOLUTION, ICAP_SUPPORTEDSIZES and CAP_FEEDERENABLED. The data returned is a CSV representation of the underlying TWAIN structures.

You can refer to the TWAIN Specification at twain.org for more information about those structures.
