From C++ I want to set the following scanner parameters using TWAIN library: resolution, window position and histogram settings (shadow, highlight, gamma, max/min intensity). Is there any good example on the web which I could use as a starting point?

BTW, is there any reason to use commercial libraries based on TWAIN and not directly TWAIN - any advantage?

you can download twain specification from twain.org and start from there. this article might help too.

for your BTW question, it's a trade-off. :) it takes time, varying from days to weeks, to learn the TWAIN specification, and it takes money to buy a commercial library. also, commercial libraries usually come with some features beyond TWAIN as well as tech support. so, it kind of depends on budget and project schedule.
