BarcodeReaderTaskSetting Object

In Dynamsoft Capture Vision(DCV), we use Json files to configure and organize the process tasks. The BarcodeReaderTaskSetting described in this chapter is one of the configurable tasks. If you have more strict requirements for speed or accuracy, it is highly recommended that you start by trying the barcode reader task settings.

Available Settings

All available parameters related to barcode decoding are listed here, along with a brief description.

Parameter Name	Description
`BarcodeFormatIds`	Sets which barcode format the current FormatSpecification configuration is applied to.
`BarcodeFormatSpecificationNameArray`	The names of the referenced BarcodeFormatSpecification object(s).
`BarcodeColourModes`	Sets the mode and priority for the barcode colour mode used to process the barcode zone.
`BarcodeComplementModes`	Sets the mode and priority to complement the missing parts in the barcode.
`DeblurModes`	Sets the mode and priority for deblurring.
`DeformationResistingModes`	Sets the mode and priority for deformation resisting.
`DPMCodeReadingModes`	Sets the mode and priority for DPM code reading.
`ExpectedBarcodesCount`	Sets the number of barcodes expected to be detected for each image.
`LocalizationModes`	Sets the mode and priority for barcode localization algorithms.
`MaxThreadsInOneTask`	Represents the maximum number of parallel threads that can be used on a single task.
`Name`	The name of the BarcodeReaderTaskSetting object.
`ReturnBarcodeZoneClarity`	Sets whether or not to return the clarity of the barcode zone.
`SectionImageParameterArray`	Sets image parameters for three different sections, where each section performs image processing stages with different parameters.
`StartSection`	Indicates which Section the task will start executing from.
`TerminateSetting`	Indicates where the task stops, specifically indicating a Stage under a certain Section.
`TextResultOrderModes`	Sets the mode and priority for the order of the text results returned.
`BaseBarcodeReaderTaskSettingName`	Sets the name of a BarcodeReaderTaskSetting object to be Inheritanced.

When DCV executes tasks related to barcode reading, it will process them according to the settings in the BarcodeReaderTaskSetting. Here is a sample:
