ExpectedBarcodesCount

ExpectedBarcodesCount is a parameter to control the number of barcodes expected to be detected. It is defined as below:

Value Type Value Range Default Value
int [0, 0x7fffffff] 0

Remarks

  • 0: detects at least one barcode.
  • N ( N > 0 ): detects N barcodes.
  • Dynamsoft Barcode Reader works as a loop trying different parameters to detect barcodes as many as possible. If ExpectedBarcodesCount is 0, the loop stops after a loop round finishes and detects at least one barcode. If ExpectedBarcodesCount is N, the loop stops once N barcodes are detected.
  • ExpectedBarcodesCount applies to each page when decoding a multi-page file.

ExpectedBarcodesCount is supported to be set through RuntimeSetting or JSON template.
