DLRReferenceRegion

Stores the reference region information.

class com.dynamsoft.dlr.DLRReferenceRegion

Attributes

localizationSourceType

The source type used to localize the reference region(s).

int localizationSourceType

Value Range

A value of EnumLocalizationSourceType Enumeration items.

Default value

LST_MANUAL_SPECIFICATION

Remarks

location

Four vertexes in a clockwise direction of a quadrilateral. Index 0 represents the left-most vertex.

Quadrilateral location

Remarks

It works only when localizationSourceType is setting to LST_MANUAL_SPECIFICATION.
The library will localize reference region(s) based on the quadrilateral set by current setting.

regionMeasuredByPercentage

Whether or not to use percentage to measure the coordinate.

int regionMeasuredByPercentage

Value Range

[0, 1]

Default value

1

Remarks

It works only when localizationSourceType is setting to LST_MANUAL_SPECIFICATION.
0: not by percentage
1: by percentage
When it’s set to 1, the values of points indicate percentage (from 0 to 100); Otherwise, they indicate coordinates in pixel.

regionPredetectionModesIndex

The index of a specific region predetection mode in the regionPredetectionModes parameter.

int regionPredetectionModesIndex

Value Range

[-1, 0x7fffffff]

Default value

-1

Remarks

It works only when localizationSourceType is setting to LST_PREDETECTED_REGION.
The library will localize reference region(s) based on the detected regions from the specified region predetection mode.
-1: all region predetection modes in the regionPredetectionModes parameter

barcodeFormatIds

The formats of the barcode in BarcodeFormat group 1.

int barcodeFormatIds

Value Range

A combined value of EnumBarcodeFormat Enumeration items

Default value

BF_ALL

Remarks

Barcode formats in EnumBarcodeFormat group 1 can be combined.
It works only when localizationSourceType is setting to LST_BARCODE.
The library will localize reference region(s) based on the barcodes whose format meets current setting.

barcodeFormatIds_2

The formats of the barcode in BarcodeFormat group 2.

int barcodeFormatIds_2

Value Range

A combined value of EnumBarcodeFormat_2 Enumeration items

Default value

BF2_NULL

Remarks

Barcode formats in EnumBarcodeFormat group 2 can be combined.
It works only when localizationSourceType is setting to LST_BARCODE.
The library will localize reference region(s) based on the barcodes whose format meets current setting.

barcodeTextRegExPattern

The regular express pattern of barcode text.

String barcodeTextRegExPattern

Remarks

It works only when localizationSourceType is setting to LST_BARCODE.
The library will localize reference region(s) based on the barcodes whose text meets current setting.
