bool UCamPanTiltDevice::isPantiltSupported ( )

inline

Get pan supported flag for this camera. NB! the flag is set when camera is opened

References pantiltSupported.

Referenced by UComCamSml::setCamDevice(), and UComCamSml::setFromCam().

bool UCamPanTiltDevice::isPantiltValid ( )

inline

Get pan tilt information valid. The flag is only valid if pan-tilt is supported NB! the flag is set when camera is opened

References pantiltValid.

bool UCamPanTiltDevice::pantiltSetPosition	(	bool	relative,
		int	pan,
		int	tilt
	)

Set pan and tilt position (must be within range). Returns true if call succeded

Referenced by UCamPool::findDevices(), getTiltPos(), and UComCamSml::setCamDevice().

bool UCamPanTiltDevice::pantiltUpdatePosition ( )

Global function to update the camera position from the camera. Returns true if position is updated. In not, then pan-tilt is most likely not supported.
