localizationSourceType
The source type used to localize the reference region(s).
Value Range
A value of DLRLocalizationSourceType Enumeration items.
Default value
DLR_LST_MANUAL_SPECIFICATION
points
Four vertices in a clockwise direction of a quadrilateral. Index 0 represents the left-most vertex.
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.
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.
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.
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.
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.
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.
