RuntimeSettings

interface RuntimeSettings

• barcodeFormatIds: number | EnumBarcodeFormat

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

  let runtimeSettings = await reader.getRuntimeSettings();
  runtimeSettings.barcodeFormatIds = Dynamsoft.DBR.EnumBarcodeFormat.BF_ONED | Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
  await reader.updateRuntimeSettings(runtimeSettings);
  

  
  

• barcodeFormatIds_2: number | EnumBarcodeFormat_2

  Sets the formats of the barcode in BarcodeFormat group 2 to be read. Barcode formats in BarcodeFormat group 1 can be combined.

  
  

• deblurLevel: number

  Sets the degree of blurriness of the barcode.

  
  

• expectedBarcodesCount: number

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

  
  

• localizationModes: number[] | EnumLocalizationMode[]

  Sets the mode and priority for localization algorithms.

  
  

• minResultConfidence: number

  
  

• region: RegionDefinition | RegionDefinition[]

  Sets the region definition including the regionTop, regionLeft, regionRight, regionBottom and regionMeasuredByPercentage.

  // Use a region of center 50% width and 50% height
  let runtimeSettings = await reader.getRuntimeSettings();
  runtimeSettings.region.regionLeft = 25;
  runtimeSettings.region.regionTop = 25;
  runtimeSettings.region.regionRight = 75;
  runtimeSettings.region.regionBottom = 75;
  runtimeSettings.region.regionMeasuredByPercentage = true;
  await reader.updateRuntimeSettings(runtimeSettings);
  

  Experimental feature:

  In BarcodeScanner, region can be an array. For example region = [r0, r1, r2], 0th frame use r0, 1st use r1, 2nd use r2, 3rd use r0, and then loop like this.

  let runtimeSettings = await reader.getRuntimeSettings();
  runtimeSettings.region = [
    null, // full image
    {regionLeft:25,regionTop:25,regionRight:75,regionBottom:75,regionMeasuredByPercentage:true}, // center 50% 
    {regionLeft:5,regionTop:45,regionRight:95,regionBottom:55,regionMeasuredByPercentage:true}, // width 90%, height 10% 
  ];
  await reader.updateRuntimeSettings(runtimeSettings);
  

  
  

• resultCoordinateType: number | EnumResultCoordinateType

  
  

• timeout: number

  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.
