Code 128, also known as ANSI/AIM 128, ANSI/AIM Code 128, USS Code 128, Uniform Symbology Specification Code 128, is a very capable linear barcode of excellent density, high reliability.

Code 128 Image Width Related Settings

W: the barcode width of Code 128. It equals to 11X (C + D/2) + 2Q + 2X. Please see BarCodeWidth.

C: the number of symbol characters (including symbol check character)

X: the width of a module bar; Xmin=1 pixel. Please see X.

Q: the width of the quiet zone; Qmin=10X. Please see Left & Right Margin.

D: the number of numeric data characters encoded in double density (Code Set C)

H: the barcode height of Code 128. Please see BarCodeHeigth.

Y: the height of a module bar. Please see Y.

Top & Bottom Margin: the height of the top & bottom margin. Please see Top & Bottom Margin.

Text Margin: the space between image bar and text. Please see TextMargin.

Text Font: the font style of human-readable text. Please see TextFont.

C# Code 128 barcode provides a set of barcode size settings to specify you Code 128 barcodes. Please download C# barcode component and install, copy those following code to your Visual Studio:

Linear barcode = new Linear();

barcode.Type = BarcodeType.CODE128;

barcode.Data = "ONBARCODE";

UOM

UOM is short for Unit of Measure, which is the unit of measure for all size related settings in the library. C# 128 barcode provides 3 options: Pixel, Cm, and Inch. The default is Pixel.

barcode.UOM = UnitOfMeasure.PIXEL;

Barcode Width & Height

BarcodeWidth is the Code 128 barcode image width. The default in C# Code 128 barcode is 0 (float).

BarcodeHeight is the Code 128 barcode image height. The default in C# Code 128 barcode is 0 (float).

barcode.BarcodeWidth = 0;

barcode.BarcodeHeigth =0;

Barcode Margin

BarcodeMargin is the white zone around the Code 128 symbol. C# Code 128 barcode provides 4 options: Left Margin, Right Margin, Top Margin and Bottom Margin. The default of these four margins are 0 (float).

barcode.TopMargin = 3;

barcode.BottomMargin = 3;

barcode.LeftMargin = 1;

barcode.RightMargin = 1;

X & Y

X is the width of barcode bar module (narrow bar). The default in C# Code 128 barcode is 1 (float).

Y is the height of barcode bar module. The default in C# Code 128 barcode is 60 (float).

barcode.X = 2;

barcode.Y = 80;

Text Margin & Font

TextMargin is the space between barcode and barcode data text. The default in C# Code 128 barcode is 6 (float).

TextFont is the font style of human-readable text. The default in C# Code 128 barcode is new Font ("Arial", 9f, FontStyle.Regular).

barcode.TextMargin = 9;

barcode.TextFont = new Font("Arial", 20f, FontStyle.Regular);
