Processor

abstract class Processor<T : VisionData?> : VisionProcessor, CameraStreamSource

Base class for all vision processors using the Vision system.

A processor will be attached to a Vision instance and will be called to process frames, allowing you to access your data here using the .getData() method. This makes it useful for tasks to access the latest data from the vision system, without needing to directly interface with the Vision instance.

Functions

clearData

open fun clearData()

Manually clear the data list.

delegate

open fun delegate(@NonNull delegateTo: Processor)

Delegate this processor to another processor.

getData

@NonNull

open fun getData(): ArrayList<T>

Get the list of vision data.

getFrameBitmap

open fun getFrameBitmap(@NonNull continuation: Continuation<out Consumer<Bitmap>>)

getId

@NonNull

abstract fun getId(): String

Unique identifier for the processor.

init

open fun init(@Nullable calibration: CameraCalibration)

Optional method to implement to access the camera calibration data.

fun init(width: Int, height: Int, @Nullable calibration: CameraCalibration)

isAttached

open fun isAttached(): Boolean

Determine whether the processor is attached to a Vision instance or is initialised.

onAttach

protected open fun onAttach()

Override this method to run any additional code that will be executed when this processor is attached (via init()) by a Vision instance.

onDrawFrame

fun onDrawFrame(@NonNull canvas: Canvas, onscreenWidth: Int, onscreenHeight: Int, scaleBmpPxToCanvasPx: Float, scaleCanvasDensity: Float, @NonNull userContext: Any)

Use onFrameDraw instead, which passes a canvas.
