Code 128 Characters Encoding in C#

Code 128 Encode Character Set

Code 128 barcode encodes the following characters

All 128 Full ASCII characters
Extended ASCII characters
4 non-data function characters
4 code set selection characters
3 Start characters and 1 Stop character

Code 128 Code Set

Code 128 barcode has three unique data character code sets. Each code set includes a subset of the full ASCII character set together with various special characters.

Code Sets A
Code Sets B
Code Sets C

Code 128 Special Characters

Code 128 has four Function Characters (FNC), four Code Set selection characters, three Start characters and one Stop character.

The Function Characters define instructions to the bar code reading device to allow for special operations and applications.

FNC1: It is for GS1 system. You can find more information about GS1-128 in C#
FNC2: It is for message append.
FNC3: It instructs the bar code reader to interpret the data from the symbol containing the FNC3 character as instructions for initialization or reprogramming of the bar code reader.
FNC4: It is used to represent an extended character set (byte values 128 to 255 in ISO/IEC 8859-1 by default)

Code 128 Check Digit

Code 128 barcode contains a mandatory check digit (checksum) character, which is using module 103 (mod 103).

The Code 128 check digit character will not be displayed in the human readable interpretation (barcode text), and it will not be returned by the barcode reader device also.

How to calculate Code 128 barcode size (image width and height) using C#.NET

Using C# Code 128 generator, you can change the Code 128 barcode dimension size through the following barcode properties:

UOM: Unit of measure. You can choose PIXEL, CM or INCH.
X: Width of narrow element. The mimumum bar width is defined by the application specification
Y: Bar module height.
LeftMargin, RightMargin: Quiet zone. the minimum width of quiet zone is 10X.

How to create a Code 128 barcode PNG image using C#.NET

C#.NET users can easily create single or multiple Code 128 image(s) independently, or you can draw and add Code 128 barcodes on various image files including popular formats like JPG, JPEG, BMP, PNG, and GIF.

Users only need to load your local image and draw Code 128 barcode on the image (after specifying location and Code 128 settings), then the barcode is drawn on the picture!

Below are the steps and C# sample source code to create a Code 128 barcode png image using C#.NET.
