Why Aspose.BarCode for Java?

In production, barcodes often come from scanners, mobile cameras, and PDFs. This SDK is built to keep decoding reliable when input is noisy, low-contrast, skewed, or partially damaged. Use QualitySettings presets to balance speed and tolerance, and apply targeted options when you need more resilience on difficult images.

Standards? Covered.

Aspose.BarCode for Java 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.

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

Cross-Platform Java Support

Aspose.BarCode for Java runs on any operating system that supports Java. It is compatible with JDK/JRE 1.8 and above, and fits common Java stacks for desktop apps, services, and web applications.

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
BarcodeGenerator gen = new BarcodeGenerator(EncodeTypes.QR, "1234567");
// Set generation parameters
gen.getParameters().getBarcode().getXDimension().setPixels(7);
gen.getParameters().getBorder().setColor(new Color(0xff000000, true));
gen.getParameters().getBorder().getWidth().setPixels(7);
// Generate and save Barcode image
gen.save("image.png", BarCodeImageFormat.PNG);

Type

Recognition quality

// Initialize BarCodeReader
BarCodeReader reader = new BarCodeReader("image.png", DecodeType.QR);
// Set recognition quality
reader.setQualitySettings(QualitySettings.getHighPerformance());
// Recognize barcodes and output results
BarCodeResult[] res = reader.readBarCodes();
System.out.printf("Recognized %d barcode(s)%n", res.length);
for (BarCodeResult result : res)
{
System.out.printf("%s: %s%n", result.getCodeTypeName(), result.getCodeText());
}

Barcode Power for Every Java Project

Aspose.BarCode for Java adds reliable barcode generation and recognition to Java systems of any size. It works well for enterprise apps, document workflows, and backend automation where you need consistent results and broad symbology coverage across environments.

With full control over barcode creation and decoding, you can:

Generate and recognize more than 80 barcode types
Read barcodes from raster images, PDFs, and streams
Handle rotated, skewed, and noisy images with configurable recognition settings
Customize size, resolution, colors, captions, and text rendering
Implement GS1, ECI, and postal barcode standards

Features and capabilities

Aspose.BarCode for Java 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.
