iPublicRuntimeSettings

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

Typedefs

@interface iPublicRuntimeSettings

Attributes

terminatePhase

Sets the phase to stop the barcode reading algorithm.

EnumTerminatePhase terminatePhase

Value range

Any one of the EnumTerminatePhase Enumeration items.

Default value

EnumTerminatePhaseRecognized

Remark

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

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.

NSInteger timeout

Value range

[0, 0x7fffffff]

Default value

10000

Remark

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.

NSInteger timeout

Value range

[1, 4]

Default value

4

Remark 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.

NSInteger expectedBarcodesCount

Value range

[0, 0x7fffffff]

Default value

0

Remark

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.

NSInteger barcodeFormatIds

Value range

A combined value of EnumBarcodeFormat Enumeration items

Default value

EnumBarcodeFormatALL

Remark

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, EnumBarcodeFormat2

barcodeFormatIds_2

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

NSInteger barcodeFormatIds_2

Value range

A combined value of EnumBarcodeFormat2 Enumeration items.

Default value

EnumBarcodeFormat2NULL

Remark

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.

pdfRasterDPI

Sets the output image resolution.

NSInteger pdfRasterDPI

Value range

[100, 600]

Default value

300

Remark

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.

NSInteger scaleDownThreshold

Value range

[512, 0x7fffffff]

Default value

2300

Remark

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.

NSArray* binarizationModes[8]

Value range

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

Default value

[EnumBinarizationModeLocalBlock, EnumBinarizationModeSkip, EnumBinarizationModeSkip, EnumBinarizationModeSkip, EnumBinarizationModeSkip, EnumBinarizationModeSkip, EnumBinarizationModeSkip, EnumBinarizationModeSkip]

Remark

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

EnumBinarizationMode

localizationModes

Sets the mode and priority for localization algorithms.

NSArray* localizationModes[8]

Value range

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

Default value

[EnumLocalizationModeConnectedBlocks, EnumLocalizationModeScanDirectly, EnumLocalizationModeStatistics, EnumLocalizationModeLines, EnumLocalizationModeSkip, EnumLocalizationModeSkip, EnumLocalizationModeSkip, EnumLocalizationModeSkip]

Remark

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

EnumLocalizationMode

furtherModes

Sets further modes.

iFurtherModes furtherModes

deblurLevel

Sets the degree of blurriness of the barcode.

NSInteger deblurLevel

Value range

[0, 9]

Default value

9

Remark

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

Sets which types of intermediate result to be kept for further reference. Intermediate result types can be combined.

NSInteger intermediateResultTypes

Value range

A combined value of EnumIntermediateResultType Enumeration items

Default value

0

NSInteger minBarcodeTextLength

Value range

[0, 0x7fffffff]

Default value

0

Remark

0: means no limitation on the barcode text length.

minResultConfidence

The minimum confidence of the result.

NSInteger minResultConfidence

Default value

0

Remark 0: means no limitation on the result confidence.
