localizationSourceType
The source type used to localize the reference region(s).
int com.dynamsoft.dlr.DLRReferenceRegion.localizationSourceType
Value Range
A value of DLRLocalizationSourceType
Enumeration items.
Default value
DLR_LST_MANUAL_SPECIFICATION
Remarks
points
Four vertexes in a clockwise direction of a quadrilateral. Index 0 represents the left-most vertex.
DLRPoint[] com.dynamsoft.dlr.DLRReferenceRegion.points
Remarks
It works only when localizationSourceType is setting to DLR_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 com.dynamsoft.dlr.DLRReferenceRegion.regionMeasuredByPercentage
Value Range
[0, 1]
Default value
1
Remarks
It works only when localizationSourceType is setting to DLR_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 com.dynamsoft.dlr.DLRReferenceRegion.regionPredetectionModesIndex
Value Range
[-1, 0x7fffffff]
Default value
-1
Remarks
It works only when localizationSourceType is setting to DLR_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 com.dynamsoft.dlr.DLRReferenceRegion.barcodeFormatIds
Value Range
A combined value of DLRBarcodeFormat
Enumeration items
Default value
DLR_BF_ALL
Remarks
Barcode formats in DLRBarcodeFormat group 1 can be combined.
It works only when localizationSourceType is setting to DLR_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 com.dynamsoft.dlr.DLRReferenceRegion.barcodeFormatIds_2
Value Range
A combined value of DLRBarcodeFormat_2
Enumeration items
Default value
DLR_BF2_NULL
Remarks
Barcode formats in DLRBarcodeFormat group 2 can be combined.
It works only when localizationSourceType is setting to DLR_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 com.dynamsoft.dlr.DLRReferenceRegion.barcodeTextRegExPattern
Remarks
It works only when localizationSourceType is setting to DLR_LST_BARCODE.
The library will localize reference region(s) based on the barcodes whose text meets current setting.
