GigE Vision Functions

The following RTX64 Vision functions can be used to discover, query, and retrieve frames from GigE Vision cameras. See the RtGigEVision sample for an example of how to use GigEVision APIs to control and receive data from a GigE Vision Camera.

Function Name	Description
RtGVClose	Closes all RtGigEVision resources.
RtGVCloseCameraControl	Closes the control channel on a camera.
RtGVCloseCameraStream	Stops a camera from sending images.
RtGVCloseReceiveStream	Closes the receive stream associated with the specified camera. Frames will no longer be received from the camera, even if it continues to send them.
RtGVCloseStream	Combines the functionality of both RtGVCloseCameraStream and RtGVCloseReceiveStream.
RtGVEnumerateCameras	Enumerates the discovered cameras on the network.
RtGVGetAcquisitionMode	Retrieves the currently configured acquisition mode of a camera.
RtGVGetCameraID	Retrieves the ID of a camera.
RtGVGetFrameHeight	Retrieves the currently configured frame height of a camera.
RtGVGetFrameMaxHeight	Retrieves the maximum frame height supported by a camera.
RtGVGetFrameMaxWidth	Retrieves the maximum frame width supported by a camera.
RtGVGetFrameNumberOfChannels	Retrieves the number of channels currently configured on a camera.
RtGVGetFrameOffsetX	Retrieves the frame X offset from the specified camera.
RtGVGetFrameOffsetY	Retrieves the frame Y offset from the specified camera.
RtGVGetFramePixelDepth	Retrieves the number of bits-per-pixel currently configured on a camera.
RtGVGetFramePixelFormat	Retrieves the currently configured pixel format on a camera.
RtGVGetFrameWidth	Retrieves the currently configured frame width of a camera.
RtGVGetManufacturerName	Retrieves the manufacturer name of a camera.
RtGVGetPayloadSize	Retrieves the currently configured pixel format on a camera.
RtGVGetLastStreamError	Retrieves the last error that occurred in the stream associated with the specified camera.
RtGVGrabFrame	Retrieves a frame from a camera.
RtGVInitCameraControl	Starts a control channel with a camera, which allows you to query and control the camera for such uses as retrieving the width of the image on the camera (using RtGVGetFrameWidth), or starting an image stream on the camera (using RtGVStartStream or RtGVStartCameraStream).
RtGVInitialize	Initializes RtGigEVision resources.
RtGVIsGEVStatusCode	Determines whether the given error code is a GEV Status Code sent by a camera.
RtGVSendTrigger	Sends a trigger to a camera, causing it to send a frame.
RtGVSetCameraCameraAcquisitionMode	Sets the acquisition mode on the specified camera.
RtGVSetFrameHeight	Sets the frame height of a camera.
RtGVSetFramePixelFormat	Sets the pixel format on a specified camera.
RtGVSetFrameWidth	Sets the frame width of a specified camera.
RtGVSetFrameOffsetX	Sets the frame X offset on the specified camera.
RtGVSetFrameOffsetY	Sets the frame Y offset on the specified camera.
RtGVStartCameraStream	Starts a stream on a camera, sending frames to the specified IP Address.
RtGVStartReceiveStream	Starts a receive stream for receiving frames from a camera.
RtGVStartStream	Combines the functionality of both RtGVStartCameraStream and RtGVStartReceiveStream.
RtGVWaitForFrame	Waits for the first packet of a frame to be received.
