Symbology

Sets the bar code's type, including the set of allowable characters. Selecting the appropriate bar code type depends on your requirements.

You may consider using the bar code Interleaved2of5 for encoding digits and bar Code39 for encoding the full range of ASCII characters.

The options for this property include:

  • Codabar: A discrete, self-checking symbology that can encode 16 different characters, as well as 4 additional start/stop characters.
    • Start Symbol: Gets or sets the first symbol used to code the bar code's structure.
    • Stop Symbol: Gets or sets the last symbol used to code the bar code's structure.
    • Wide Narrow Ratio: Gets or sets the density of a bar code's bars.
  • Code 11: A discrete symbology that is able to encode numbers 0 to 9, the dash (-) symbol, and start/stop characters.
  • Code128: A high-density symbology that can encode alphanumeric data. The symbology includes a checksum digit for verification. The bar code can also be verified character-by-character, allowing the parity of each data byte to be verified.
    • Character Set: Gets or sets the character set type for the bar code. The character set options include:
      • CharsetA: Includes ASCII characters 00 to 95, special characters and FNC 1.
      • CharsetB: Includes ASCII characters 32 to 127, special characters, and FNC 1.
      • CharsetC: Includes ASCII digit strings and FNC 1.
      • CharsetAuto: Uses A, B and C character sets and switches between them automatically according to bar code text.
  • Code39: Can encode 43 characters.
    • Wide Narrow Ratio: Gets or sets the density of a bar code's bars.
    • Calculate a Checksum: Gets or sets whether to calculate a checksum for the bar code.
  • Code39Extended: Can encode all 128 ASCII characters. This is accomplished by using the dollar ($), forward slash (/), percent (%), and plus (+) symbols as shift characters. These characters combined with the single character that follows indicate which Full ASCII character is to be used.

    The Code39Extended option automatically replaces all necessary characters with special symbols when required. You do not need to manually encode special characters, otherwise the result will be incorrect.

    • Wide Narrow Ratio: Gets or sets the density of a bar code's bars.
    • Calculate a Checksum: Gets or sets whether to calculate a checksum for the bar code.
  • Code93: Can represent the full ASCII character set by using combinations of 2 characters. Uses a continuous symbology and produces denser code than Code39. It also encodes 47 characters.
    • Calculate a Checksum: Gets or sets whether to calculate a checksum for the bar code.

    A checksum of a Code93 can contain characters that are not supported by this bar code symbology. For this reason, the checksum is not included in the Code93 text.

  • Code93Extended: Can encode all 128 ASCII characters. This is accomplished by using the dollar ($), forward slash (/), percent (%), and plus (+) symbols as shift characters. These characters combined with the single character that follows indicate which Full ASCII character is to be used.
    • Calculate a Checksum: Gets or sets whether to calculate a checksum for the bar code.

    A checksum of a Code93 can contain characters that are not supported by this bar code symbology. For this reason, the checksum is not included in the Code93 text.

  • CodeMSI: A continuous, non-self-checking symbology. A MSI bar code can be of any length.
