PublicRuntimeSettings

Defines a struct to configure the barcode reading runtime settings. These settings control the barcode recognition process such as which barcode types to decode.

Attributes

terminatePhase

Sets the phase to stop the barcode reading algorithm.

int com.dynamsoft.dbr.PublicRuntimeSettings.terminatePhase

Value Range
Any one of the EnumTerminatePhase Enumeration items

Default Value
TP_BARCODE_RECOGNIZED

Remarks
When the recognition result is not desired, you can set this parameter can be set to skip certain processing stages.

See Also
EnumTerminatePhase

timeout

Sets the maximum amount of time (in milliseconds) that should be spent searching for a barcode per page. It does not include the time taken to load/decode an image (TIFF, PNG, etc.) from disk into memory.

int com.dynamsoft.dbr.PublicRuntimeSettings.timeout

Value Range
[0, 0x7fffffff]

Default Value
10000

Remarks
If you want to stop reading barcodes after a certain period of time, you can use this parameter to set a timeout.

maxAlgorithmThreadCount

Sets the number of threads the image processing algorithm will use to decode barcodes.

int com.dynamsoft.dbr.PublicRuntimeSettings.timeout

Value Range
[1, 4]

Default Value
4

Remarks
To keep a balance between speed and quality, the library concurrently runs four different threads for barcode decoding by default.

expectedBarcodesCount

Sets the number of barcodes expected to be detected for each image.

int com.dynamsoft.dbr.PublicRuntimeSettings.expectedBarcodesCount

Value Range
[0, 0x7fffffff]

Default Value
0

Remarks
0: means Unknown and it will find at least one barcode. 1: try to find one barcode. If one barcode is found, the library will stop the localization process and perform barcode decoding. n: try to find n barcodes. If the library only finds m (m<n) barcode, it will try different algorithms till n barcodes are found or all algorithms are tried.

barcodeFormatIds

Sets the formats of the barcode in BarcodeFormat group 1 to be read. Barcode formats in BarcodeFormat group 1 can be combined.

int com.dynamsoft.dbr.PublicRuntimeSettings.barcodeFormatIds

Value Range
A combined value of EnumBarcodeFormat Enumeration items

Default Value
BF_ALL

Remarks
If the barcode type(s) are certain, specifying the barcode type(s) to be read will speed up the recognition process. The barcode format our library will search for is composed of BarcodeFormat group 1 and BarcodeFormat group 2, so you need to specify the barcode format in group 1 and group 2 individually.

See Also
EnumBarcodeFormat, EnumBarcodeFormat_2

barcodeFormatIds_2

Sets the formats of the barcode in BarcodeFormat group 2 to be read. Barcode formats in BarcodeFormat group 2 can be combined.

int com.dynamsoft.dbr.PublicRuntimeSettings.barcodeFormatIds_2

Value Range
A combined value of EnumBarcodeFormat_2 Enumeration items

Default Value
BF2_NULL

Remarks
If the barcode type(s) are certain, specifying the barcode type(s) to be read will speed up the recognition process. The barcode format our library will search for is composed of BarcodeFormat group 1 and BarcodeFormat group 2, so you need to specify the barcode format in group 1 and group 2 individually.

EnumBarcodeFormat, EnumBarcodeFormat_2

pdfRasterDPI

Sets the output image resolution.

int com.dynamsoft.dbr.PublicRuntimeSettings.pdfRasterDPI

Value Range
[100, 600]

Default Value
300

Remarks
When decoding barcodes from a PDF file using the DecodeFile method, the library will convert the PDF file to image(s) first, then perform barcode recognition.

scaleDownThreshold

Sets the threshold for the image shrinking.

int com.dynamsoft.dbr.PublicRuntimeSettings.scaleDownThreshold

Value Range
[512, 0x7fffffff]

Default Value
2300

Remarks
If the shorter edge size is larger than the given threshold value, the library will calculate the required height and width of the barcode image and shrink the image to that size before localization. Otherwise, the library will perform barcode localization on the original image.

binarizationModes

Sets the mode and priority for binarization.

int[] com.dynamsoft.dbr.PublicRuntimeSettings.binarizationModes

Value Range
Each array item can be any one of the EnumBinarizationMode Enumeration items.

Default Value
[BM_LOCAL_BLOCK,BM_SKIP,BM_SKIP,BM_SKIP,BM_SKIP,BM_SKIP,BM_SKIP,BM_SKIP]

Remarks
The array index represents the priority of the item. The smaller index is, the higher priority is.

See Also
EnumBinarizationMode

localizationModes

Sets the mode and priority for localization algorithms.

int[] com.dynamsoft.dbr.PublicRuntimeSettings.localizationModes

Value Range
Each array item can be any one of the EnumLocalizationMode Enumeration items.

Remarks
The array index represents the priority of the item. The smaller index is, the higher priority is.

deblurLevel

Sets the degree of blurriness of the barcode.

int com.dynamsoft.dbr.PublicRuntimeSettings.deblurLevel

Value Range
[0, 9]

Default Value
9

Remarks
If you have a blurry image, you can set this property to a larger value. The higher the value set, the more effort the library will spend to decode images, but it may also slow down the recognition process.

intermediateResultTypes
