Why Aspose.Barcode for .NET?

The barcode library supports various settings to scan and decode damaged or distorted barcodes. It allows successfully reading barcode images with various defects, such as Gaussian noise, inverted colors, white spots, visual artifacts, colored background, and missing bars. To improve barcode readability, the API enables special methods and mechanisms, including median filtering, ‘salt-and-paper’ filtering, reducing image size, and others. Moreover, the barcode library benefits from advanced methods to decode industrial Data Matrix barcodes, read severely damaged QR codes, and even restore some data from incorrect barcodes.

Standards? Covered.

Aspose.BarCode for .NET Aspose.Barcode supports all major image formats, including vector formats like SVG and EMF, as well as PDF. Use our API to recognize files from scanners or cameras with ease. Here are all supported barcode symbologies, including 1D, 2D, postal, and composite types. Each one can be generated and recognized across all supported platforms.

Platform independence

Aspose.Barcode for .NET is designed for true platform independence, supporting all major desktop, server, and mobile operating systems — including Windows, Linux, macOS, Android, iOS, and Tizen — with compatibility across .NET Framework, .NET Core, Mono, and .NET MAUI.

Live Code Demo

Paste text → get a barcode. Drop a file → get decoded data. Both examples come with auto-generated sample code so you can copy straight into your project.

Type

Text

X-dimension

Border color

Image format

/** Initialize BarcodeGenerator */
var gen = new BarcodeGenerator(EncodeTypes.QR, "1234567");
/** Set generation parameters */
gen.Parameters.Barcode.XDimension.Pixels = 7;
gen.Parameters.Border.Color = Color.FromArgb(0xff000000);
gen.Parameters.Border.Width.Pixels = 7;
/** Generate and save Barcode image */
gen.Save("image.png", BarCodeImageFormat.Png);

Type

Recognition quality

/** Initialize BarCodeReader */
var reader = new BarCodeReader("image.png", DecodeType.QR);
/** Set recognition quality */
reader.QualitySettings = QualitySettings.HighPerformance;
/** Recognize barcodes and output results */
var res = reader.ReadBarCodes();
Console.WriteLine($"Recognized {res.Length} barcode(s)");
foreach (BarCodeResult r in res)
    Console.WriteLine($"{r.CodeTypeName}: {r.CodeText}");

Unlimited possibilities

Aspose.Barcode for .NET unlocks advanced barcode capabilities for developers across a wide range of industries. Whether you’re building enterprise systems, automating document workflows, or integrating barcode processing into desktop, mobile, or cloud apps — the API gives you full control over how barcodes are generated, styled, and decoded. Designed with flexibility and performance in mind, it seamlessly fits into complex environments and high-volume pipelines.

With a rich feature set and enterprise-grade performance, you can:

Generate and recognize over 60 barcode types
Work with PDF, SVG, EMF, and all major image formats
Detect barcodes in low-resolution or distorted images
Fine-tune appearance, size, margins, and rotation
Embed barcodes into reports, documents, or UIs with ease

Features and capabilities

Aspose.BarCode for .NET is a powerful development library to generate & recognize 1D & 2D barcodes from various image types at any angle. This API allows exporting generated barcodes to different high-quality image formats, enables modifying the appearance of generated barcodes and their parameters, such as background color, bar color, rotation angle, x-dimension, image quality, resolution, captions, size, and many others. It also provides rich barcode detecting and reading functionality and supports over 60 barcode types.
