BitmapFrameSource

Defined in package com.scandit.datacapture.core.source

BitmapFrameSource

class BitmapFrameSource : FrameSource

Added in version 6.3.0

Emits a frame from the provided Bitmap.

To emit the frame set this object as the frame source for the DataCaptureContext and turn it on by changing the desired state to FrameSourceState.ON. This frame source will turn off automatically after the frame is emitted.

Note

This frame source emits a single image and turns off again. To feed a continuous stream of frames from a camera your application owns, use SequenceFrameSource instead — see Sequence Frame Source.

fromJson(json)

fun ImageFrameSource.fromJson(json: String): BitmapFrameSource?

Added in version 6.14.0

Constructs a new BitmapFrameSource from the provided JSON, which should have the format {“image”:”<base64>”}, where <base64> is the Base64 encoding of a ARGB_8888 bitmap.

of(bitmap)

fun ImageFrameSource.of(bitmap: Bitmap): BitmapFrameSource

Added in version 6.3.0

Constructs a new BitmapFrameSource from the provided Bitmap. This Bitmap is required to have config ARGB_8888.

desiredState

val desiredState: FrameSourceState

Added in version 6.3.0

Implemented from FrameSource. See FrameSource.desiredState.

currentState

val currentState: FrameSourceState

Added in version 6.3.0

Implemented from FrameSource. See FrameSource.currentState.

addListener(listener)

fun addListener(listener: FrameSourceListener)

Added in version 6.3.0

Implemented from FrameSource. See FrameSource.addListener().

removeListener(listener)

fun removeListener(listener: FrameSourceListener)

Added in version 6.3.0

Implemented from FrameSource. See FrameSource.removeListener().

switchToDesiredState(desiredState, whenDone)

fun switchToDesiredState(desiredState: FrameSourceState,
        whenDone: Callback<Boolean>?)

Added in version 6.3.0

Implemented from FrameSource. See FrameSource.switchToDesiredState().
