6 Defining Device-Specific Properties

6-4

Determine the device the user wants to establish a connection with, specified by

device ID.

Determine the format the user wants to use with the device, specified by format

name (or the path of a camera file). To get format information, retrieve the

IDeviceFormat object associated with the format from the IDeviceInfo object.

Create any device-specific properties. You create a property object appropriate to the

data type of the property and store the property object in the device-specific property

container — see “Creating Device Properties” on page 6-5.

Find all trigger configurations supported by the device and store the information in

the ITriggerInfo object — see “Supporting Hardware Triggers” on page 5-27.

There are several ways your adaptor can determine this property, source, and trigger

information:

• By querying the device SDK at run-time

• By reading information from an imaging device file (IMDF). If you know the device

information in advance, you can store it in an IMDF file using an XML-based markup

language. This section describes how to read information from an IMDF file. To

learn how to create an IMDF file, see “Using the IMDF Markup Language” on page

7-2.

• A mixture of both methods.
