1. Code-128 Introduction
Code-128 is also known as ANSI/AIM
128, ANSI/AIM Code 128, USS Code 128, Uniform Symbology Specification Code 128,
Code 128 Code Set A, Code 128 Code Set B, Code 128 Code Set C, Code 128A, Code
128B, Code 128C
Compatibility: Barcode Generator Software is compatible with ISO/IEC 15417 (Second edition 2007-06-01)
Code 128 is a very effective, high-density symbology which permits the encoding of alphanumeric data. The symbology includes a checksum digit for verification, and the bar code may also be verified character-by-character verifying the parity of each data byte. This symbology has been widely implemented in many applications where a relatively large amount of data must be encoded in a relatively small amount of space. It's specific structure also allows numeric data to be encoded at, effectively, double-density.

Code 128 Code Sets
- Code Set A (or Chars Set A) includes all of the standard upper case U.S. alphanumeric keyboard characters and punctuation characters together with the control characters, (i.e. characters with ASCII values from 0 to 95 inclusive), and seven special characters.
- Code Set B (or Chars Set B) includes all of the standard upper case alphanumeric keyboard characters and punctuation characters together with the lower case alphabetic characters (i.e. characters with ASCII values from 32 to 127 inclusive), and seven special characters.
- Code Set C (or Chars Set C) includes the set of 100 digit pairs from 00 to 99 inclusive, as well as three special characters. This allows numeric data to be encoded as two data digits per symbol character, at effectively twice the density of standard data.
Code 128 Special characters
The last seven characters of Code Sets A and B (character
values 96 - 102) and the last three characters of Code Set C (character values
100 - 102) are special non-data characters with no ASCII character equivalents,
which have particular significance to the bar code reading device.

2. Code-128 Encoding Data Scope
Code 128 Barcode for .NET, ASP.NET supports:
- all 128 characters of ASCII
3. Code-128 Property Settings
-
Set the Type property to BarcodeType.CODE128, BarcodeType.CODE128A, or BarcodeType.CODE128B, or BarcodeType.CODE128C.
- default (auto):Barcode Library will automatically switch between code sets to encode the ASCII values.
- A: Library will use the Char Set A which only supports ASCII values from 0 to 95
- B: Library will use the Char Set B which only supports ASCII values from 32 to 127
- C: Library will use the Char Set C which only supports pairs of digits
- Set the Data property with the value to encode. Type is string.
-
Setting up barcode image size:
-
Set property UOM (Unit of Measure) for properties BarWidth, BarHeight, LeftMargin and TopMargin.
Default is UnitOfMeasure.Pixel (0). Valid values are UnitOfMeasure.Pixel (0), UnitOfMeasure.CM (1), UnitOfMeasure.Inch (2). - Set the BarWidth (for bar cell width) and BarHeight (for bar cell height) properties. Both types are float.
- Set the LeftMargin and TopMargin properties, and types are both float.
- Set the Resolution property (Value is expressed in DPI - Dots per inch). This property is not working in Windows Controller, we will use end user's windows resultion.
-
Set property UOM (Unit of Measure) for properties BarWidth, BarHeight, LeftMargin and TopMargin.
-
Setting up text style in barcode image:
- Set the ShowText properties. If this value is true, barcode data will be displayed with the barcode.
- Set the TextFont property. The font used to display text in barcode image.
- Set the Format property for barcode image type. Value can be "gif", "jpg", "png", and "bmp", default is "png".
- Set BearerBars property, if you want to draw borders around barcode image. Value can be BearerBar.None (no bear bars), BearerBar.Frame (top, bottom, left, right borders drawn), BearerBar.TopBottom (only top, bottom's are drawn).
-
Set Rotate property, if you want to rotate barcode image.
Value can be
0 (RotateOrientation.BottomFacingDown),
1 (RotateOrientation.BottomFacingLeft),
2 (RotateOrientation.BottomFacingUp),
3 (RotateOrientation.BottomFacingRight) - AddCheckSum property is not applied here. Barcode Library will always add a check character between encoded data and stop character (modulo 103).
