Detailed Description

An interface used to provide input image data for processing. API users should obtain a reference to this interface by using SDKProvider::GetFrameProvider function.

Member Function Documentation

AddFrame() [1/2]

int com.visagetechnologies.bsc.FrameProvider.AddFrame ( com.visagetechnologies.CamIL.Image  frame )

inline

Enqueues image for processing, replacing the last queued Image. When processing is triggered the engine obtaines only the last queued frame.

Parameters

newFrame

Image for processing.

Returns

sequential frame index.

AddFrame() [2/2]

int com.visagetechnologies.bsc.FrameProvider.AddFrame ( java.nio.ByteBuffer  data, int  width, int  height, com.visagetechnologies.bsc.ColorModel  model  )

inline

Enqueues image for processing, replacing the last queued Image. When processing is triggered the engine obtaines only the last queued frame.

Parameters

newFrame

Image for processing.

Returns

sequential frame index.

ReuseInputFrame()

com.visagetechnologies.CamIL.Image com.visagetechnologies.bsc.FrameProvider.ReuseInputFrame ( )

inline

Returns previous input image. Use this method to reuse memory and avoid unnecessary allocations/dealocations that could cause a performance hit.

Use this only when new frame has the same format, width and height as the returned image. If format, width or height don't match, create a new CamIL::Image.

Subscribe()

void com.visagetechnologies.bsc.FrameProvider.Subscribe ( com.visagetechnologies.fpr.IFrameObserver  observer )

inline

Subscribe to receive notifications when a new frame is ready.

Parameters

observer

Object reference to receive notifications when new frame is enqueued.

Unsubscribe()

void com.visagetechnologies.bsc.FrameProvider.Unsubscribe ( com.visagetechnologies.fpr.IFrameObserver  observer )

inline

Subscribe to stop receiving notifications.

Parameters

observer

Subscribed observer reference you wish to cancel.
