TpsPDF417 class
Declaration
property SecurityLevel: psPDF417ErrorCorrection;
psPDF417ErrorCorrection = (psPDF417AutoEC, psPDF417Error0, psPDF417Error1,
psPDF417Error2, psPDF417Error3, psPDF417Error4,
psPDF417Error5, psPDF417Error6, psPDF417Error7, psPDF417Error8);
Description
One of PDF417's most valuable features is its ability to allow correction of errors. The number of damaged codewords (NMax) which may be recovered depends on the security level.
psPDF417AutoEC - set error level automatic depend on number of used codewords
psPDF417Error0 - no error correction, NMax=0
psPDF417Error1 - NMax = 2
psPDF417Error2 - NMax = 6
psPDF417Error3 - NMax = 14
psPDF417Error4 - NMax = 30
psPDF417Error5 - NMax = 62
psPDF417Error6 - NMax = 126
psPDF417Error7 - NMax = 254
psPDF417Error8 - NMax = 510
Tip:
Use SecurityLevel=psPDF417AutoEC , this is good for print optimized barcode.
