LazBarcodes

About

LazBarcodes is a set of controls to create 1D and 2D barcodes. The backend engine is a port of Zint at sourceforge. Some units were heavily refactored to obtain a more Pascal-like code.

The library supports the generation of 1D and 2D barcodes:

1D barcodes

• TBarcodeC11:
  • Code-11: max 121 numeric characters ('0'..'9')

• TBarcodeC128: Property BarcodeType allows to select one of the subsets:
  • bctC128: Code-128 - max 160 text characters (ASCII)
  • bctEAN128: UPC/EAN-128, also known as GS1-128] - variable length depending on "Application Identifier" to be given in square brackets.

• TBarcode2of5: Property BarcodeType allows to select one of the following subsets:
  • bctCode25Standard: Standard 2-of-5, also known as Matrix 2-of-5 - up to 80 numerical digits
  • bctCode25DataLogic: DataLogic 2-of-5 - up to 80 numerical digits
  • bctCode25IATA: IATA_2_of_5 - up to 45 numerical digits
  • bctCode25Industrial: Industrial 2-of-5 - up to 45 numerical digits
  • bctCode25Interleaved: Interleaved 2-of-5 - up to 89 numerical digits
  • bctITF14: ITF-14 - up to 13 numerical digits

• TBarcode3of9: supports the following subsets via property BarcodeType:
  • bctCode39: Code 3-of-9 (C39) - up to 74 characters: numeric, uppercase-alpha and some special characters (-. $/+%abcd).
  • bctCode39Ext: Extended Code 3-of-9 (C39+) - up to 74 characters, all ASCII characters allowed (< #128).
  • bctLOGMARS: LOGMARS - like C39, different wide bar width.
  • bctCode93: Code-93 - up to 107 characters like C39.

• TBarcodeEAN: supports the following subsets via property BarcodeType:
  • bctEAN: EAN-8 and EAN-13 - up to 13 numeric digits
  • bctEAN14: EAN-14 - up to 13 numeric digits
  • bctISBN: ISBN - 9, 10 or 13 numeric characters or 'X'
  • bctNVE18: NVE-18 - up to 25 numeric digits
  • bctUPCA: UPC-A - up to 10 numeric digits (plus 2 check digits)
  • bctUPCE: UPC-E - up to 7 numeric digits

2D barcodes

• TLazBarcodeQR: QR Code
• TLazBarcodeMicroQR: MicroQR
• TLazBarcodeAztec: Aztec Code
• TLazBarcodeAztecRun: Aztec Rune
• TLazBarcodeDataMatrix: DataMatrix

The download contains the packages "lazbarcodes" and "lazbarcodes_runtimeonly". The first one gives you visual components of the above barcodes and the second can be used just to access the ported zint code for advanced barcode generation.

• Initial development.

Dependencies / System Requirements

• None

Status: In development

Issues: None by now.

Installation

• Step 1: Compile the package "lazbarcodes_runtimeonly".
• Step 2: Install the package "lazbarcodes".

Final notes

If you need the generation of another barcode and it is present in Zint, please ask for it in the Lazarus forum or mailing lists.
