Getting and Setting Capabilities

Each TWAIN source can support a number of capabilities. These capabilities dictate the behavior of the TWAIN source. Before acquiring images from the selected TWAIN source, the user may wish to examine and change the capability settings for that source.

It is possible to check whether the scanner installed on the system supports certain capabilities. For more information, refer to "How to Find Out Whether Your Scanner Supports Certain Capabilities Using Twacker", which can be found on https://www.leadtools.com/support/forum/. Search for "How to Find Out Whether Your Scanner Supports Certain Capabilities Using Twacker".

LEADTOOLS provides both low-level and high-level functions for getting and setting capabilities. The low-level functions get and set capabilities individually. The high-level functions let the user get and set specific capabilities, either singly or in groups.
