There were settings in my scanner drivers that would cause the machine to scan just the actual image area and fill an 8 x 11 image, eliminating the unwanted border.
I was unable to find any documentation that told me how to access those particular settings programmatically. I ended up just using the Twack application to set those properties. The drivers remember the settings via an ini file so once I set the properties, they will not be changed.
So I am sorry to say I never did come up with a way to use TWAIN to crop the images.
