Barcode Reader SDK (Developer Updated List)

Published April 19, 2023

Introduction

A barcode is an image that can be read by machines. Initially, barcodes used different lengths of parallel lines and spacings to represent data. Various specialized optical scanners, known as barcode readers, can detect these linear or one-dimensional (1D) barcodes. Later, "matrix codes" were developed for two-dimensional (2D) variations that do not use bars, but instead utilize rectangles, dots, hexagons, and other designs. 2D barcodes can be scanned using specialized multi-configuration 2D optical readers. It is also possible to photograph a 2D barcode while it is being broken down and decoded using image processing software on a digital camera connected to a computer. Mobile devices with built-in cameras, such as smartphones, can also perform this type of 2D barcode scanning with the help of specialized application software.

In this article, we will explore the top five Barcode generator SDKs:

Scandit Barcode SDK

IronBarcode

Using .NET apps and web pages with IronBarcode, programmers can read and create barcodes/QR codes. IronBarcode only requires one line of code to scan or generate QR codes. The bulk of barcode and QR standards can be read and written using this .NET Barcode library. To know more the IronBarcode can visit the link here.

Code 39/93/128, UPC A/E, EAN 8/13, ITF, RSS 14 / Expanded, Databar, CodaBar, Aztec, Data Matrix, PDF417, MaxiCode, USPS, MSI, Plessey, , and Normal QR are a few of the more well-known formats that IronBarcode supports. IronBarcode can generate barcodes as text, binary data, page, and image files.

The following is a summary of IronBarcode's API features:

The majority of barcode types and QR standards, such as UPC A/E, EAN 8/13, Code 39/93/128, ITF, MSI, RSS 14/Expanded, Databar, and CodaB, are read and written by IronBarcode.
Aztec, MaxiCode, PDF417, PDF417 Styled, Data Matrix, and QR. The findings' barcode data, type, page, text, and barcode image are ideal for indexing or archiving systems.
Improved reading efficiency and precision, IronBarcode preprocesses barcode images instantly. The precision and speed of reading are enhanced by image pre-processing. It can detect scans or live video frames and correct rotation, noise, distortion, and skewing. Batch processing server programs have access to multiple cores and processes. Find one or more barcodes automatically in single and multi-page texts, without having to use difficult APIs. We can search for particular barcode types or document locations.
When used with .NET projects, get up and running fast with just a few lines of code. It has no dependencies, supports 32- and 64-bit architectures, and can be used with any .NET or .NET core languages because it was created as a unique DLL for the .NET Framework. It supports console, desktop, cloud, and web apps on both desktop and mobile platforms.
For a variety of file and stream types, such as PDF, JPG, TIFF, GIF, BMP, PNG, and HTML, you can create barcodes and QR codes. Our works can also be saved and printed in file or stream forms. The text's rotation, height, color, and quality can all be altered.

Create Barcode Using IronBarcode

IronBarcode enables the creation of barcode labels that can be saved in a variety of image formats. We can also specify the type of barcode we want to create. Below is a sample code for creating barcodes:


    var MyBarCode = BarcodeWriter.CreateBarcode("123",BarcodeEncoding.Code128)
    MyBarCode.AddAnnotationTextBelowBarcode("123");
    MyBarCode.SaveAsImage("BarCode.jpeg");


    var MyBarCode = BarcodeWriter.CreateBarcode("123",BarcodeEncoding.Code128)
    MyBarCode.AddAnnotationTextBelowBarcode("123");
    MyBarCode.SaveAsImage("BarCode.jpeg");

Dim MyBarCode = BarcodeWriter.CreateBarcode("123",BarcodeEncoding.Code128) MyBarCode.AddAnnotationTextBelowBarcode("123")
	MyBarCode.SaveAsImage("BarCode.jpeg")

VB C#

There is a static method named CreateBarcode in the BarcodeWriter class of the IronBarcode namespace. The CreateBarcode function requires two string values to be sent as parameters, one for each type of barcode. Additionally, it is optional to specify the height and width of the bars when using the CreateBarcode function to generate barcodes.

After receiving the parameters, the function will return the barcode object, which in turn provides various barcode attributes that can be modified, as demonstrated in the example code mentioned above. One of the features is AddAnnotationTextBelowBarcode, which allows us to add text below or above the barcode labels. If needed, the barcode text can also be made invisible. In the aforementioned code, the JPEG encoder is utilized for handling barcodes. The generated QR codes can be saved in various image formats and printed in high resolution without sacrificing image clarity.

In addition to image files, we can also export barcodes in HTML format. Different image formats can be used to create and save different types of barcodes. Furthermore, we can read multiple barcodes from a single barcode image.


    var QRWithLogo = QRCodeWriter.CreateQrCodeWithLogo("Hello World", "logo.png", 500);
    QRWithLogo.ChangeBarCodeColor(System.Drawing.Color.DarkGreen);
    QRWithLogo.SaveAsJpeg("Logoqr.jpeg");


    var QRWithLogo = QRCodeWriter.CreateQrCodeWithLogo("Hello World", "logo.png", 500);
    QRWithLogo.ChangeBarCodeColor(System.Drawing.Color.DarkGreen);
    QRWithLogo.SaveAsJpeg("Logoqr.jpeg");

Dim QRWithLogo = QRCodeWriter.CreateQrCodeWithLogo("Hello World", "logo.png", 500)
	QRWithLogo.ChangeBarCodeColor(System.Drawing.Color.DarkGreen)
	QRWithLogo.SaveAsJpeg("Logoqr.jpeg")

VB C#

The above-mentioned example illustrates how we can use the image embedded within a QR code to create a barcode using the CreateQrCodeWithLogo function. Furthermore, we are utilizing the ChangeBarCodeColor function, which enables us to modify the color of the barcode or QR code. These capabilities of IronBarcode can be particularly useful when creating unique barcodes for business purposes, allowing for customization and differentiation.

Conclusion

The aforementioned four SDKs do not provide options for creating barcodes and have limitations in barcode reading. They also require registration for trial licenses and have expensive costs, with unclear documentation.

On the other hand, IronBarcode is one of the best libraries for generating and recognizing barcodes. It is efficient and compatible with various operating systems. It supports multiple barcode types and allows for customization of barcode attributes such as wording, color, line width, and height. It comes with an unlimited license, allowing for use in multiple applications. It also offers excellent customer service. You can find licensing information here.
