Attributes

regionPredetectionModesIndex int
barcodeFormatIds int
barcodeFormatIds_2 int

reserved char[64]

localizationSourceType

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

DLRLocalizationSourceType tagDLRReferenceRegion::localizationSourceType

points

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

DLRPoint tagDLRReferenceRegion::points[4]
  • 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 tagDLRReferenceRegion::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 tagDLRReferenceRegion::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 tagDLRReferenceRegion::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 tagDLRReferenceRegion::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.

char tagDLRReferenceRegion::barcodeTextRegExPattern[64]
  • 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.

reserved

Reserved memory for struct. The length of this array indicates the size of the memory reserved for this struct.

char tagDLRReferenceRegion::reserved[64]
