About Contexts

Much of the information that is passed between the WIA service, a WIA minidriver, and a WIA device is in the form of a context of one kind or another. These can be WIA service contexts (also known as application item contexts), property contexts, transfer contexts, or device-specific contexts. Each type of context is discussed in the following topics in this section:

Application Item Contexts

Property Contexts

Transfer Contexts

Device-Specific Contexts
