Class OutputFrameBuffer

Namespace
easyar

Output frame buffer. There is an output frame input port and an output frame acquisition function, used to convert the acquisition method of output frames from asynchronous to synchronous polling, suitable for frame-by-frame rendering. OutputFrameBuffer occupies one camera buffer. Use the camera's setBufferCapacity to set no less than the number of camera buffers occupied by all components. All members of this class are thread-safe.

OutputFrameBuffer

Methods

input

Input port.

void easyar_OutputFrameBuffer_input(easyar_OutputFrameBuffer * This, easyar_OutputFrameSink * * Return)
std::shared_ptr<OutputFrameSink> input()
public @Nonnull OutputFrameSink input()
fun input(): OutputFrameSink
- (easyar_OutputFrameSink *)input
public func input() -> OutputFrameSink
public virtual OutputFrameSink input()

Returns

OutputFrameSink

bufferRequirement

The number of camera buffers occupied by the current component.

int easyar_OutputFrameBuffer_bufferRequirement(easyar_OutputFrameBuffer * This)
int bufferRequirement()
public int bufferRequirement()
fun bufferRequirement(): Int
- (int)bufferRequirement
public func bufferRequirement() -> Int32
public virtual int bufferRequirement()

Returns

Int32

signalOutput

Arrival signal output port. Can be used to connect signalInput.

void easyar_OutputFrameBuffer_signalOutput(easyar_OutputFrameBuffer * This, easyar_SignalSource * * Return)
std::shared_ptr<SignalSource> signalOutput()
public @Nonnull SignalSource signalOutput()
fun signalOutput(): SignalSource
- (easyar_SignalSource *)signalOutput
public func signalOutput() -> SignalSource
public virtual SignalSource signalOutput()

Returns

SignalSource

peek

Acquire the latest OutputFrame.

void easyar_OutputFrameBuffer_peek(easyar_OutputFrameBuffer * This, easyar_OptionalOfOutputFrame * Return)
std::optional<std::shared_ptr<OutputFrame>> peek()
public @Nullable OutputFrame peek()
fun peek(): OutputFrame?
- (easyar_OutputFrame *)peek
public func peek() -> OutputFrame?
public virtual Optional<OutputFrame> peek()

Returns

Optional<OutputFrame>

create

Create.

void easyar_OutputFrameBuffer_create(easyar_OutputFrameBuffer * * Return)
static std::shared_ptr<OutputFrameBuffer> create()
public static @Nonnull OutputFrameBuffer create()
companion object fun create(): OutputFrameBuffer
+ (easyar_OutputFrameBuffer *)create
public static func create() -> OutputFrameBuffer
public static OutputFrameBuffer create()

Returns

OutputFrameBuffer

pause

Pause output of OutputFrame. After execution, the result of peek is empty. signalOutput is unaffected.

void pause()
public void pause()
fun pause(): Unit
- (void)pause
public func pause() -> Void
public virtual void pause()

Returns

Void

resume

Resume output of OutputFrame.

void easyar_OutputFrameBuffer_resume(easyar_OutputFrameBuffer * This)
void resume()
public void resume()
fun resume(): Unit
- (void)resume
public func resume() -> Void
public virtual void resume()

Returns

Void
