Detailed Description

Interface implemented by the barcode picker classes to control the barcode scanning process.

To scan barcodes, instantiate one of the classes implementing the ScanditSDK interface:

ScanditSDKBarcodePicker is the most flexible of the available picker classes and is able run in a separate full-screen activity as well as in a view hierarchy.
LegacyPortraitScanditSDKBarcodePicker is intended for older devices that only allow the camera to be previewed in landscape mode. It "fakes" the portrait mode by rotating all displayed controls accordingly. This picker is only able to run in full-screen in a separate activity.
ScanditSDKAutoAdjustingBarcodePicker selects between the legacy portrait picker and the more flexible standard barcode picker. If your app is using barcode scanning in a separate full-screen activity, it is recommended to use this picker.

Class Documentation

enum com::mirasense::scanditsdk::interfaces::ScanditSDK::WorkingRange

Enumerates the possible working ranges for the barcode picker.

Since: 4.1.0

Class Members
	STANDARD_RANGE	The camera tries to focus on barcodes which are close to the camera. To scan far-away codes (30-40cm+), user must tap the screen. This is the default working range and works best for most use-cases. Only change the default value if you expect the users to often scan codes which are far away.
	LONG_RANGE	The camera tries to focus on barcodes which are far from the camera. This will make it easier to scan codes that are far away but degrade performance for very close codes.
	HIGH_DENSITY

enabled Whether this mode should be enabled.

Implemented in ScanditSDKBarcodePicker.

void force2dRecognition ( boolean force )

Forces the barcode scanner to always run the 2D decoders (QR, Datamatrix, etc.), even when the 2D detector did not detect the presence of a 2D code.

This slows down the overall scanning speed, but can be useful when your application only tries to read QR codes. It is by default enabled when the micro Datamatrix mode is enabled.

By default, this is disabled.

Parameters

force boolean indicating whether this mode should be enabled.

Since: 2.0.0

Implemented in ScanditSDKBarcodePicker.

void setScanningHotSpot	(	float	x,
		float	y
	)

Sets the location in the image where barcodes are decoded with the highest priority.

This method shows a slightly different behavior depending on whether the full screen scanning is active or not. In Full screen scanning mode:

Sets the location in the image which is decoded with the highest priority when multiple barcodes are present in the image.

In restrictActiveScanningArea mode (activated with restrictActiveScanningArea(boolean)):

Changes the location of the spot where the barcode decoder actively scans for barcodes.

X and Y can be between 0 and 1, where 0/0 corresponds to the top left corner and 1/1 to the bottom right corner.

The default hotspot is set to 0.5/0.5

See also: ScanditSDKBarcodePicker.restrictActiveScanningArea(boolean); ScanditSDKBarcodePicker.setScanningHotSpotHeight(float)

Since: 1.0.0

Parameters

x	The hotspot's relative x coordinate.
y	The hotspot's relative y coordinate.

Implemented in ScanditSDKBarcodePicker.

void setScanningHotSpotHeight ( float height )

Changes the height of the area where barcodes are decoded in the camera image when restrictActiveScanningArea is activated.

The height of the active scanning area is relative to the height of the screen and has to be between 0.0 and 0.5.

This only applies if the active scanning area is restricted.

The default is 0.25

See also: ScanditSDKBarcodePicker.restrictActiveScanningArea(boolean); ScanditSDKBarcodePicker.setScanningHotSpot(float, float)

Since: 1.0.0

Parameters

height The relative height of the active scanning area.

Implemented in ScanditSDKBarcodePicker.

void restrictActiveScanningArea ( boolean restrict )

Reduces the area in which barcodes are detected and decoded.

When activated, the active scanning area is defined by setScanningHotSpotHeight(float) and setScanningHotSpot(float, float)

Parameters

restrict

Implemented in ScanditSDKBarcodePicker.

void switchTorchOn ( boolean on )

Switches the torch on or off.

If the torch button is enabled on the overlay, users can change this by clicking it.

Since: 2.0.0

Parameters

on	Whether the torch should be on.

Implemented in ScanditSDKBarcodePicker.

void setWorkingRange ( WorkingRange range )

Sets the focus working range for the barcode picker.

The working range tells the engine at which distance barcodes are to be expected. When set to STANDARD_RANGE (the default), the focus is optimized for barcodes close to the camera. When set to LONG_RANGE, the focus is optimized for far-away codes.

When using non-standard working range, it is better to directly pass the working range when constructing the barcode picker, because the camera can already start to adjust the focus at an earlier point in time.

See com.mirasense.scanditsdk.interfaces.ScanditSDK.WorkingRange for a list of possible values.

The working range hint is ignored on cameras with fixed-focus.

Since: 4.1.0

Parameters

range the working range

Implemented in ScanditSDKBarcodePicker.

void setZoom ( float zoomPercentage )

Sets the zoom to the given percentage of the max zoom possible.

Parameters

zoomPercentage The percentage of the max zoom (between 0 and 1).

Implemented in ScanditSDKBarcodePicker.

void setZoom ( int zoom )

Sets the zoom level as defined by the Android Camera.

Parameters

zoom	Zoom level (0 to max zoom)

Implemented in ScanditSDKBarcodePicker.

void setCaptureListener ( ScanditSDKCaptureListener listener )

Sets a listener object for capture events.

Parameters

listener The listener.
