Description property

Prototype

String Description

Comments

This is a read only property that returns a textual representation of the FireiXFixedStreamFormat. The

text contains the pixel format and the resolution of the streaming format. A typical description would look

like:

Y_MONO, 160 X 120

It is also the same value returned by the Description property of the FireiXStreamFormat from which

this FireiXFixedStreamFormat was derived from.

Visual Basic 6.0 syntax

Dim Description As String

Description = Fixed.Description

C++ syntax

BSTR Description;

HRESULT hr = pIFixed->get_Description(&Description);

IsFrameRateSupported method

Prototype

Boolean IsFrameRateSupported(IN FireiXFrameRate FrameRate)

Comments

This method will return True if the supplied FireiXFrameRate is both available in this

FireiXFixedStreamFormat and acceptable by the camera and the current conditions of the 1394 bus.

A frame rate may not be available on a given Fixed streaming format, as defined in the IIDC spec. It may also

not be supported by the camera; these are static conditions. There are dynamic conditions though, such as

the isochronous speed of the bus the camera is connected to, limited by both hardware and software. Some

frame rates may require a higher isochronous speed than what is available currently, and even though the

camera may support the frame rate, it might not be currently achievable. In all those cases,

IsFrameRateSupported will return False.

Visual Basic 6.0 syntax

Dim Supported As Boolean

Supported = Fixed.IsFrameRateSupported fps30

C++ syntax

VARIANT_BOOL bSupported;

HRESULT hr = pIFixed->IsFrameRateSupported(fps30, &bSupported);
