public CameraControlForLiveStream(ADBase adBase)

Method Details

startAcquiring

public void startAcquiring()
                    throws DeviceException

Start acquiring data

Set the ImageMode to CONTINUOUS for live stream.

Specified by:

startAcquiring in interface CameraControl

Overrides:

startAcquiring in class EpicsCameraControl

Throws:

DeviceException

setAcquireTime

public void setAcquireTime(double acquiretime)
                    throws DeviceException

Set acquire (exposure) time

Set the acquire period to the same as the acquire time (exposure time). Of course each detector will have a different physical 'readout' time so the period will always be longer but it should be up to the specific AD driver to manage this itself and adjust the period accordingly.

Specified by:

setAcquireTime in interface CameraControl

Overrides:

setAcquireTime in class EpicsCameraControl

Parameters:

acquiretime - in seconds

Throws:

DeviceException

setContinuousImageMode

public void setContinuousImageMode(int continuousImageMode)

setStreamTriggerMode

public void setStreamTriggerMode(Integer streamTriggerMode)
