C# GS1 128 (UCC/EAN 128) barcode provides a set of barcode size settings to specify you GS1 128 (UCC/EAN 128) barcodes. Please download C# barcode component and install, copy those following code to your Visual Studio:

Linear barcode = new Linear();

barcode.Type = BarcodeType.EAN128;

barcode.Data = "(01)ONBARCODE";

Modify your GS1 128 (UCC/EAN 128) barcodes by setting those following properties:


UOM is short for Unit of Measure, which is the unit of meature for all size related settings in the library. C# GS1 128 (UCC/EAN 128) barcode provides 3 options: Pixel, Cm, and Inch. The default is Pixel.

barcode.UOM = UnitOfMeasure.PIXEL;

Barcode Width & Height

BarcodeWidth is the GS1 128 (UCC/EAN 128) barcode image width. The default in C# GS1 128 (UCC/EAN 128) barcode is 0 (float).

BarcodeHeight is the GS1 128 (UCC/EAN 128) barcode image height. The default in C# GS1 128 (UCC/EAN 128) barcode is 0 (float).

barcode.BarcodeWidth = 0;

barcode.BarcodeHeigth =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 GS1 128 (UCC/EAN 128) barcode image.
