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

Linear barcode = new Linear();

barcode.Type = BarcodeType.UPCA;

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# UPC-A barcode provides 3 options: Pixel, Cm, and Inch. The default is Pixel.

barcode.UOM = UnitOfMeasure.PIXEL;

Supplement Space

SupplementSpace is the space between the UPC-A 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 UPC-A barcode bar). The default is 0.8f (float).

barcode.SupplementSpace = 0.5f;

Barcode Width & Height

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

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

barcode.BarcodeWidth = 0;

barcode.BarcodeHeight = 0;

Barcode Margin

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

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

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