Why Aspose.BarCode for C++?

Real-world scans are rarely perfect. Aspose.BarCode for C++ is designed to decode barcodes from damaged or distorted images, including noise, glare, skew, low contrast, and missing elements. Tune quality settings to balance speed and tolerance, and use built-in cleanup options such as median and salt-and-pepper filtering when the input is messy.

Standards? Covered.

Aspose.BarCode for C++ 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.

Matrix / 2D Codes

QR Code, MicroQR, rMQR
Data Matrix, Industrial Data Matrix (DPM)
Aztec
Han Xin
MaxiCode
DotCode

Linear / 1D Codes

UPCA, UPCE
EAN13, EAN14, EAN8
Code 128
DataBar
ITF
Postal

Industry & Composite Codes

Native Windows, Mac and Linux Support

Aspose.BarCode for C++ is a native library for Windows, Mac and Linux. It targets x64 applications and fits common C++ toolchains, including Visual Studio and CMake builds with MSVC, GCC, or Clang.

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
auto gen = System::MakeObject<BarcodeGenerator>(EncodeTypes::QR, u"1234567");
// Set generation parameters
gen->get_Parameters()->get_Barcode()->get_XDimension()->set_Pixels(7.0f);
gen->get_Parameters()->get_Border()->set_Color(System::Drawing::Color::FromArgb((int32_t)0xff000000));
gen->get_Parameters()->get_Border()->get_Width()->set_Pixels(7.0f);
// Generate and save Barcode image
gen->Save(u"image.png", Aspose::BarCode::Generation::BarCodeImageFormat::Png);

Type

Recognition quality

// Initialize BarCodeReader
auto reader = System::MakeObject<BarCodeReader>(u"image.png", DecodeType::QR);
// Set recognition quality
reader->set_QualitySettings(QualitySettings::get_HighPerformance());
// Recognize barcodes and output results
auto res = reader->ReadBarCodes();
System::Console::WriteLine(System::String(u"Recognized ") + res->get_Length() + u"barcode(s)");
for (System::SharedPtr<BarCodeResult> r : res)
System::Console::WriteLine(r->get_CodeTypeName() + u": " + r->get_CodeText());

Fast, Native Barcode Processing

Aspose.BarCode for C++ delivers high-performance barcode generation and recognition for native applications. Build engineering tools, industrial systems, desktop utilities, or server-side services with a library designed for accuracy and efficiency. Recognition stays reliable on rotated, skewed, or low-quality images, and generation gives you precise control for print, screen, or embedded workflows.

With full support for 1D and 2D barcode standards, you can:

Generate and recognize 80+ barcode symbologies
Work with common raster formats such as PNG, JPEG, BMP, and TIFF
Read barcodes from noisy, distorted, or rotated images with high accuracy
Customize resolution, padding, orientation, captions, and text settings
Integrate barcodes into desktop apps, embedded systems, or back-end services

Features and capabilities

Aspose.BarCode for C++ 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 80 barcode types.
