7 Storing Adaptor Information in an IMDF File

7-16

Specifying Format Information

To specify the video formats supported by a particular device in an IMDF file, use the

VideoFormat element. VideoFormat nodes must be children of Device nodes. In the

VideoFormat node, you specify the name of the format as the value of an attribute of the

element.

You can also specify format-specific property and trigger information, if necessary.

A VideoFormat node can have Property and TriggerInfo nodes as children.

(VideoFormat nodes can also have a Section node as a child — see “Defining and

Including Sections” on page 7-21.)

The following example outlines how to use the VideoFormat node. The words in italics

represent text that you define.

<Property constraint=constraint_value

deviceSpecific=true_or_false

name=property_name

readOnly=always_never_or_whileRunning

type=cell_double_int_or_string

min=minimum_value

max=maximum_value

optional=on_or_off

default=default_value>

</Property>

</TriggerInfo>

</VideoFormat>

</Device>

</ImageAcquisitionInfo>

The following table lists the tags used to specify video format information.
