RtgvGetFrameOffsetY

RtgvGetFrameOffsetY retrieves the frame Y offset, in pixels, from the specified camera.

Syntax

BOOL RtgvGetFrameOffsetY(
    [in]    UINT32 cameraHandle, 
    [out]   PUINT32 pOffsetY
);

Parameters

[in] cameraHandle

The handle of the camera whose frame Y offset is being queried.

[out] pOffsetY

A pointer to the frame Y offset, in pixels, on the specified camera.

Return Values

If the function succeeds, it returns TRUE. If the function fails, it returns FALSE. Call GetLastError to obtain an error code.

Remarks

This function will fail if it is called before RtgvInitialize and RtgvInitCameraControl.

To find the camera to query, call RtgvInitialize and then call RtgvEnumerateCameras to get an RTGV_CAMERA_INFO array describing each camera found on the network, along with its handles.
