ExpectedBarcodesCount

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

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.
