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

Linear barcode = new Linear();

barcode.Type = BarcodeType.POSTNET;

barcode.Data = "12345";

UOM

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

barcode.UOM = UnitOfMeasure.PIXEL;

Short to Tall Ratio

ShortTallRatio is the proportion of short and tall bar (Y). The default in C# POSTNET barcode is 0.4f (float).

barcode.ShortTallRatio = 0.5f;

Barcode Width & Height

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

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

barcode.BarcodeWidth = 0;

barcode.BarcodeHeigth =0;

Barcode Margin

BarcodeMargin is the white zone around the POSTNET symbol. C# POSTNET 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# POSTNET barcode is 1 (float).

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

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

barcode.TextMargin = 9;

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