PDF 417, a multi-row 2-D barcode symbology, has a unique physical structure and large data capacity.
PDF417 empowers you to encode more than 1000 alpha-numeric characters within one symbol. PDF417 is able to encode ASCII and Extended ASCII characters.
PDF417 barcode is able to encode up to 1000 alpha-numeric characters. Therefore, PDF417 barcode is a good solution for encoding large quantities of data in one symbol.
Reed Solomon algorithm is used for error checking and correcting of PDF417. The higher security level is, the larger pdf417 symbol size will be, and the less decipher error chance. If not specified, default security level of 0 will be used. This security level means automatic security selection.
You can use either Barcodesoft PDF417 Encoder or crUFLbcs.dll to encode your data on Windows PC.
Solution for MicroPDF417 barcode is also included in the package.
crUFLbcs.dll has a IPDF417 interface. IPDF417 interface has 2 methods: Encode and EncodeCR.
Encode accepts only one string parameter as input. it returns encoded codewords.
Encode(strToEncode)
EncodeCR accepts 7 parameters as input. It returns encoded codewords.
EncodeCR(strToEncode, index, MaxRow, FixedColumn, Security, CompactionMode, Truncated)
The first parameter is a string to encode.
The second parameter is a long variable. When set to zero, it returns all codewords. When set to 1, it returns the first 250 codewords. When set to 2, it returns the second 250 codewords.
The third parameter is a long variable. It sets the Max Rows of a PDF417 barcode.
The fourth parameter is a long variable. It sets the column number of a PDF417 barcode.
The fifth parameter is a long variable. It sets the security level of a PDF417 bar code. When set to zero, it means automatic security selection. Security level ranges from zero to nine.
The sixth parameter is a long variable. It sets the compaction mode of PDF417 barcode. Zero means mixed mode, 1 means Text Mode, 2 means Numeric Mode, 3 means Binary Mode.
The seventh parameter is a long variable. It sets the PDF417 to be truncated or not.
