The Code 128 Auto barcode specification is used in IDAutomation Barcode Fonts, Components and Applications to create a Code 128 Auto Barcode with automatic character set switching. Code 128 Auto generates the most area-efficient barcode symbol and easily encodes ASCII 0-126, which includes numbers, upper and lower case letters, several symbols, and the GS1 FNC-1 function. The ApplyTilde option is available in Auto mode, which enables other options such as the easy generation of GS1-128 barcodes.
- Using Code 128 Auto Barcode Fonts with a font encoder returns text formatted to the Code 128 Barcode specifications.
- Using Uni_Code128 with a Universal Barcode Font Encoder returns text formatted to the Universal Barcode Font and the GS1 DataBar Barcode Font.
- The Code128 barcode option in all Components and Applications will produce a barcode image that includes all applicable start and stop digits with checksum characters when required.
- Nat_Code128a creates a “native” barcode from pure text without installing fonts or components. These options exist in the Native Barcode Generators for Crystal Reports, Access, FileMaker, JavaScript, and Oracle Reports.
