Member Function Documentation

◆ BeginAcquisition()

void BeginAcquisition ( )

virtual

BeginAcquisition Starts the image acquisition engine.

The camera must be initialized via a call to Init() before starting an acquisition.

Note that an error SPINNAKER_ERR_NOT_IMPLEMENTED will be thrown if an unsupported combination of stream mode and buffer ownership is set.

See also: Init()

Implements ICameraBase.

◆ DeInit()

void DeInit ( )

virtual

DeInit Disconnects camera port, resets camera back to read access and frees GenICam node map and GUI XML.

Do not call more functions that access the remote device such as WritePort/ReadPort after calling DeInit(). Events should also be unregistered before calling camera DeInit(). Otherwise an exception will be thrown in the DeInit() call and require the user to unregister events before the camera can be re-initialized again.

See also: Init(); UnregisterEventHandler(EventHandler & evtHandlerToUnregister)

Implements ICameraBase.

◆ DEPRECATED_FUNC()

DEPRECATED_FUNC	(	"Use GetDeviceID() instead."	,
		GenICam::gcstring GetUniqueID();
	)

GetUniqueID This returns a unique id string that identifies the camera.

Returns: string that uniquely identifies the camera (serial number)

◆ DiscoverMaxPacketSize()

unsigned int DiscoverMaxPacketSize ( )

virtual

DiscoverMaxPacketSize Returns the largest packet size that can be safely used on the interface that device is connected to.

Returns: The maximum packet size returned.

Implements ICameraBase.

◆ EndAcquisition()

void EndAcquisition ( )

virtual

EndAcquisition Stops the image acquisition engine.

If EndAcquisition() is called without a prior call to BeginAcquisition() an error message "Camera is not started" will be thrown. All Images that were acquired using GetNextImage() or GetNextImageSync() need to be released first using image->Release() or imageList->Release() before calling EndAcquisition(). All buffers in the input pool and output queue will be discarded when EndAcquisition() is called.

See also: Init(); BeginAcquisition(); GetNextImage( grabTimeout ); GetNextImageSync( grabTimeout ); Image::Release()

Implements ICameraBase.

◆ ForceIP()

void ForceIP ( )

virtual

ForceIP Forces the camera to be on the same subnet as its corresponding interface.

Implements ICameraBase.

GetActiveNumDataStreams Returns the number of data streams that are currently active.

Returns: The number of active data streams

Implements ICameraBase.

◆ GetBufferOwnership()

BufferOwnership GetBufferOwnership ( ) const

virtual

		uint64_t	streamIndex = `0`
	)

virtual

GetNextImage Gets the next image that was received by the transport layer.

This function will block for the specified timeout period until an image arrives. Most cameras support one stream so the default streamIndex is 0, but if a camera supports multiple streams the user can input the streamIndex to select from which stream to grab images.

See also: Init(); BeginAcquisition(); EndAcquisition()

Parameters

grabTimeout	A 64bit value that represents a timeout in milliseconds
streamIndex	The index of the stream to grab the image from

This function will block for the specified timeout period until an image arrives on all the streams.

Note: This function should not be used together with GetNextImage. Results will be undeterministic and could lead to missing or lost of images.

See also: Init(); BeginAcquisition(); EndAcquisition()

Parameters

grabTimeout A 64bit value that represents a timeout in milliseconds

Returns: a list containing the Image objects
