Remarks

This property determines whether a barcode is duplicated in another location in the image.

LEADTOOLS provides a number of functions to let you work with duplicated barcodes. They let you:

  • Find the number of duplicates of a specific barcode
  • Determine whether a specific barcode is duplicated
  • Get the index of the first duplicated barcode
  • Get the index of a subsequent barcode

To determine whether a barcode is duplicated, use the IsDuplicated property. If a barcode is duplicated, the DuplicatedIndex property will return the index of the first barcode in the array after the specified barcode, which is a duplicate of the specified barcode. The DuplicateCount property will get the total number of barcodes duplicated for the current barcode.

If you know the index of a barcode within an array, use the IndexDuplicate property to get the next instance of a duplicated barcode.

Target Platforms: Microsoft .NET Framework 3.0, Windows XP, Windows Server 2003 family, Windows Server 2008 family
