Setting EAN-8 Barcode Size in C#

C# EAN-8 barcode provides a set of barcode size settings to specify you EAN-8 barcodes. Please download C# barcode component and install, copy those following code to your Visual Studio:

Linear barcode = new Linear();

barcode.Type = BarcodeType.EAN8;

barcode.Data = "1234567";

Modify your EAN-8 barcodes by setting those following properties:


UOM is short for Unit of Measure, which is the unit of measure for all size related settings in the library. C# EAN-8 barcode provides 3 options: Pixel, Cm, and Inch. The default is Pixel.

barcode.UOM = UnitOfMeasure.PIXEL;

Supplement Space

SupplementSpace is the space between the EAN-8 barcodes and supplemental data. The default is 15 (float).

barcode.SupplementSpace = 19;

Supplement Height

SupplementHeight is the height of the supplement data bar module. It is the N percent of Y (module height of EAN-8 barcode bar). The default is 0.8f (float).

barcode.SupplementSpace = 0.5f;

Barcode Width & Height

BarcodeWidth is the EAN-8 barcode image width. The default in C# EAN-8 barcode is 0 (float).

BarcodeHeight is the EAN-8 barcode image height. The default in C# EAN-8 barcode is 0 (float).

barcode.BarcodeWidth = 0;

barcode.BarcodeHeight = 0;

Notice: if your setting is smaller than the barcode required minimum width and height, the library will automatically reset to barcode minimum width. Or you may enable AutoResize to automatically resize your EAN-8 barcode image.

Barcode Margin

BarcodeMargin is the white zone around the EAN-8 symbol. C# EAN-8 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# EAN-8 barcode is 1 (float).

Y is the height of barcode bar module. The default in C# EAN-8 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# EAN-8 barcode is 6 (float).

TextFont is the font style of human-readable text. The default in C# EAN-8 barcode is new Font ("Arial", 9f, FontStyle.Regular).

barcode.TextMargin = 9;

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