Comments

This function acquires one or more images from a TWAIN source and stores them in the specified bitmap list. If the user wants to acquire one or more images and process each one individually, he or she should use the LTwain::Acquire function an provide an LTwain::BitmapCallBack function for processing each image.

The number of pages to acquire can be determined by getting the TWAIN source's capabilities. To change the number of pages to acquire, set the appropriate capability to the desired number.
