Spire.Barcode is a free .NET component specially designed for developers. It can generate many kinds of barcode such as EAN128, Codabar, DataMatrix, PostNet and so on. It can also scan the barcode images. X dimension is the measure of the narrowest bar in a barcode. Barcodes and scanners have different X dimensions, so they must be matched. Using Spire.Barcode, it is quiet an easy job to do this.
In this document, I will introduce you how to so.
Step 1: Create a BarcodeSettings instance.
BarcodeSettings setting = new BarcodeSettings();
Step 2: Set the data to render.
setting.Data = "58465157484"; setting.Data2D = "58465157484";
Step 3: Set the type of barcode to generate.
setting.Type = BarCodeType.UPCA;
Step 4: Set the value of X dimension.
setting.Unit = GraphicsUnit.Millimeter; setting.X = 0.8F;
The property Unit specifies the measurement unit. In this sample, the measurement unit is millimeter.
Step 5: Generate barcode image using BarCodeGenerator.
BarCodeGenerator gen = new BarCodeGenerator(setting);
Image img = gen.GenerateImage();
img.Save("barcode.png");
Screenshot and Full Code:
using Spire.Barcode;
using System.Drawing;
namespace SetXDimension
{
class Program
{
static void Main(string[] args)
{
BarcodeSettings barsetting = new BarcodeSettings();
//set the x dimension
barsetting.X = 0.8f;
barsetting.Unit = GraphicsUnit.Millimeter;
barsetting.HasBorder = true;
barsetting.BorderWidth = 0.5F;
//set the data
barsetting.Data = "58465157484";
barsetting.Data2D = "58465157484";
//generate UPCA barcode
barsetting.Type = BarCodeType.UPCA;
BarCodeGenerator bargenerator = new BarCodeGenerator(barsetting);
Image barcodeimage = bargenerator.GenerateImage();
barcodeimage.Save("barcode.png");
System.Diagnostics.Process.Start("barcode.png");
}
}
}
