I can't seem to find any 15.0 documentation or examples for TWAIN scanning.

It seems much of the API has changed so I'm a bit lost on how to continue. For example, session.IsAvailable is gone.

The scanner we are planning on using is the fujitsu fi-4030-c. We want to write a user interface (and to suppres the TWAIN UI) so the user can:

1.) Select "Black and White" (tiff bi-tonal at 240 dpi.) or "Color" (png 24 color at 180 dpi).

2.) Select between the "ADF" or "Flatbed" (I've been having a difficult time forcing the scanner to use the flatbed).

Any example code for accomplishing these objectives would be appreciated (again 15.0 code is non-existent).

IsAvailable still exists in LEADTOOLS 15. Which programming interface are you using (C++ classes, Dot NET classes, etc.)?

About choosing color resolution (pixel depth) before scanning, use the ICAP_PIXELTYPE capability.

About the feeder, set CAP_FEEDERENABLED to True to enable using the document feeder, or false to disable it (and use the flatbed).

For more details about any of these capabilities, please refer to the Twain specification v1.9 (from http://www.twain.org)

If you want more help with our implementation, please specify which programming interface and programming language you're using.

The IsAvailable method is still there in v15 in the TwainSession class.  Are you having any problems using it?

Also, were you able to use the capabilities described above?
