Why Use a Barcode Generator?

Barcodes are used in various settings, from logistics to retail, and are invaluable for helping companies keep track of inventory, streamline delivery systems, and more. Barcodes improve data accuracy and speed, reduce errors, and boost operational efficiency, highlighting their importance in organizing and managing information across diverse fields.

Today, we will be taking a dip into the topic of barcode generation, exploring various use cases in which a barcode generator is needed, and exploring the IronBarcode library. IronBarcode is a robust tool that simplifies generating barcodes in C# projects, making it easy and efficient to create, customize, and read barcodes. By creating barcodes programmatically, you can streamline the barcode generation process, therefore raising the efficiency of your workplace.

By the end of our time together today, you will have been introduced to IronBarcode, explored some of its powerful features, and be armed with the skills you need to start using it in your workspace like a pro.

Getting Started Quickly

Create a Visual Studio Project

Start by creating a new project in Visual Studio.
1. Open Visual Studio.
2. Choose a project template (e.g., Console Application).
3. Configure project settings (name, location).
4. Select the target framework (e.g., .NET 7).

Install the IronBarcode Library

Using the NuGet package manager console, enter the following command to install the barcode library:

Install-Package Barcode

To install the library via the NuGet Package Manager window go to tools>NuGet Package Manager>Manage NuGet Packages for Solution and search for IronBarcode.

After installation, add the necessary namespace to your project:

using Ironbarcode;

Generate a Barcode from a URL

Generating barcodes from a URL can be helpful in many different work environments, from inventory management such as linking an item's barcode to that product's information, or in event management when a ticket's barcode could link to a page containing all of the event information.

This example will take you through the simple process of generating a barcode from a URL and then saving it as a PNG image.

using IronarCode;

//Generates the barcode using a URL
GeneratedBarcode barcode =   BarcodeWriter.CreateBarcode("https://ironsoftware.com/csharp/barcode/", BarcodeEncoding.Code128);

//Saves the generated barcode image as a PNG
barcode.SaveAsPng("barcode.png");

This code uses the BarcodeWriter.CreateBarcode method to generate barcode images with the specified data and encoding type then saves the barcode image as "barcode.png".

Customization and Styling

Add Annotation Text and Barcode Value to Your Barcode

You can add annotation text and barcode value to the barcode image to provide additional context.

//Generate a barcode using a URL
GeneratedBarcode barcode = BarcodeWriter.CreateBarcode("https://ironsoftware.com/csharp/barcode/", BarcodeEncoding.Code128);

//Add some annotation text above the barcode image
barcode.AddAnnotationTextAboveBarcode("This is Sample Barcode");

//Add the value text below the barcode
barcode.AddBarcodeValueTextBelowBarcode();

//Save the barcode as a PNG
barcode.SaveAsPng("annotatedBarcode.png");

The above code adds annotation text above the barcode and the barcode value below it, making the barcode more informative.

Set Dimensions

To style the barcode, specify its width and height.

//Generate the barcode and set it's width and height
GeneratedBarcode barcode = BarcodeWriter.CreateBarcode("https://ironsoftware.com/csharp/barcode/", BarcodeEncoding.Code128,600,150);
barcode.SaveAsPng("resizedBarcode.png");

This code generates a barcode with a width of 600 and a height of 150 pixels.

Change Colors

You can also customize the background and barcode colors. This can be especially helpful when you want to improve accessibility, changing the colors of the barcode can greatly improve the contrast and make it easier to see. Another reason to change the barcode colors would be to make it more visually appealing and stand out.

using IronBarCode;

//Generate the barcode and set it's dimensions
GeneratedBarcode barcode = BarcodeWriter.CreateBarcode("https://ironsoftware.com/csharp/barcode/", BarcodeEncoding.Code128,600,150);

//Change the background color
barcode.ChangeBackgroundColor(IronSoftware.Drawing.Color.DarkKhaki);
//Change the Barcode color
barcode.ChangeBarCodeColor(IronSoftware.Drawing.Color.DarkOrange, true);

//save the barcode
barcode.SaveAsPng("coloredBarcode.png");

This code changes the background color to DarkKhaki and the barcode color to DarkOrange, enhancing the visual appeal.

Reading Barcodes

To read a barcode from an image, use the following code:

var resultFromFile = BarcodeReader.Read(@"barcode.png");
            foreach (var barcodeValue in resultFromFile)
            {
                Console.WriteLine(barcodeValue);
            }

This code reads the barcode data from the image file "barcode.png" and prints the detected barcode values to the console.
