The code requires a 6 digit article number (digits 0-9). // The check digit is calculated by Zint. EAN-2 and EAN-5 add- on // symbols can be added using the + character as with UPC-A. In // addition Zint also supports Number System 1 encoding by entering a // 7-digit article number stating with the digit 1. test "UPCE", BarcodeGeneratorMBS.BarcodeUpcE, "1123456" // European Article Number (EN 797) 6.1.4.1 EAN-2, EAN-5, EAN-8 and EAN-13 // The EAN system is used in retail across Europe and includes // standards for EAN-2 and EAN-5 add-on codes, EAN-8 and EAN-13 which // encode 2, 5, 7 or 12 digit numbers respectively. Zint will decide // which symbology to use depending on the length of the input data. // In addition EAN-2 and EAN-5 add-on symbols can be added using the + // symbol as with UPC symbols. test "EAN", BarcodeGeneratorMBS.BarcodeEanx, "54321" test "EAN", BarcodeGeneratorMBS.BarcodeEanx, "7432365+54321" // Standard Code 39 was developed in 1974 by Intermec. // Input data can be of any length and supports the characters 0-9, A- // Z, dash (-), full stop (.), space, asterisk (*), dollar ($), slash // (/), plus (+) and percent (%). The standard does not require a // check digit but a modulo-43 check digit can be added if required by // setting Option2 = 1. test "Code39", BarcodeGeneratorMBS.BarcodeCode39, "CODE39" // PDF417 (ISO 15438) // Heavily used in the parcel industry, the PDF417 symbology can // encode a vast amount of data into a small space. Zint supports // encoding up to the ISO standard maximum symbol size of 925 // codewords which (at error correction level 0) allows a maximum data // size of 1850 text characters, or 2710 digits. The width of the // generated PDF417 symbol can be specified at the command line using // the Option2 with a number between 1 and 30, and the amount of check // digit information can be specified by using the Option1 property // with a number between 0 and 8 where the number of codewords used // for check information is determined by 2(value + 1). The default // level of check information is determined by the amount of data // being encoded. International text support is provided using the // Latin-1 character set as described in Appendix A. A separate // symbology ID can be used to encode Health Industry Barcode (HIBC) // data which adds a leading '+' character and a modulo-49 check digit // to the encoded data. test "PDF417", BarcodeGeneratorMBS.BarcodePdf417, "Hello World, Just a test. 123" // 6.6.1 Data Matrix (ISO 16022) Also known as Semacode this symbology // was developed in 1989 by Acuity CiMatrix in partnership with the US // DoD and NASA. The symbol can encode a large amount of data in a // small area. Data Matrix can encode any characters in the Latin-1 // set and can also encode GS1 data. The size of the generated symbol // can also be adjusted using Option2. A separate symbology ID can be // used to encode Health Industry Barcode (HIBC) data which adds a // leading '+' character and a modulo-49 check digit to the encoded // data. Note that only ECC200 encoding is supported, the older // standards have now been removed from Zint. An extra feature is // available for Data Matrix symbols which allows Zint to // automatically resize the symbol as required but also prevents Zint // from using rectangular symbols. To set this mode at the command // line use Option3 = OptionSquare. test "DataMatrix", BarcodeGeneratorMBS.BarcodeDatamatrix, "Hello World" // QR Code // Also known as Quick Response Code this symbology was developed by // Denso.
