IronBarcode

The C# Barcode Library

# Read and Write QR & Barcodes in .Net Applications

# Fast & Accurate using Scans or Images

# Built for the .Net Framework

Overview

Recognizes Many Different Barcode & QR Types

IronBarcode reads and generates the majority of barcode and QR standards including UPC A/E, EAN 8/13, Code 39, Code 93, Code 128, ITF, MSI, RSS 14/Expanded, Databar, CodaBar, QR, Styled QR, Data Matrix, MaxiCode, PDF417, Plessey, and Aztec. Results provide barcode data, type, page, text, and barcode image; ideal for archive or indexing systems.

Fast & Accurate Reading with Image Pre Processing

IronBarcode automatically preprocesses barcode images to improve speed and accuracy. Correcting rotation, noise, distortion and skewing to read scans or live video frames. Multi core, multi thread ready for batch processing server applications. Automatically find one or multiple barcodes in single and multi-page documents. Search for specific barcode types or document locations without the need for complex APIs.

Built for easy use in .Net Projects

Get started in minutes with a few lines of code. Built for the .Net Framework as an easy to use single DLL; without dependencies; supporting 32 & 64 bit; in any .Net Language. Use in Web, Cloud, Desktop or Console Applications; supporting Mobile & Desktop devices.

Write Barcodes & QRs to Multiple Formats

Save or Print to a file or stream, as PDF, JPG, TIFF, GIF, BMP, PNG, or HTML formats. Set colour, quality, rotation, size and text. Use the C# Barcode Programming toolbox along with IronPDF and IronOCR for a full .Net Document Library.

Iron Barcode Features

IronBarCode is a .NET library allowing developers to read and generate barcodes. This leading .Net barcode library IronBarCode supports a wide range of 1 and 2 dimensional barcodes including decorated (colored and branded) QR codes.

Barcode Reading Features

Get Started Quickly

IronBarcode.BarcodeReader Static Class API makes barcode and QR reading a 1 line task.

The QuicklyReadOneBarcode and QuicklyReadAllBarcodes methods have automatic settings which analyze your input documents and make judgement calls on all advanced settings, suitable for the majority of use cases.

This gives ease of use while providing a calculated balance of speed vs accuracy.

Read Any Image or PDF

Supports barcode reading from:

Jpeg, Jpeg2000, Png, Bmp, Tiff & Gif Image formats from files
System.Drawing.Image, System.Drawing.Bitmap Objects and System.IO.Stream
Read one or many frames from within multi-page GIF and TIFF images
Read Barcodes from PDF documents on single, multiple or all pages

IronBarcode.BarcodeReader Settings

Greater accuracy and performance

Specify the reader to scan for 1, many or all BarcodeFormats for greater accuracy and performance
Choose to specify Crop Areas within scanned document regions to increase accuracy and efficiency
BarcodeResult image objects, can be disabled to further increase performance
Automatically managed Multithreading for batch barcode scanning and and also for reading multiple pages within Multi-Frame Tiffs, Gifs and PDFs

Image Correction to Read Barcodes that other libraries can not

Document noise and contrast correction to read imperfect scans and photographs
Orientation correction which will un-rotate and remove perspective from images to make distorted barcodes readable
Repairs small (thumbnail) images or land digital noise within barcodes to make them readable
Full support of all native image formats including opacity

IronBarcode.BarcodeReader Output

Text barcode Data. (all.Net text encodings supported, default as UTF-8)
Numerica Data
Binary Data
A System.Drawing.Bitmap of the Barcode which was read

Barcode Writing Features

Developer Friendly

A fault tolerant barcode and QR writing API using the BarcodeWriter and QRCodeWriter static classes. In most cases, Barcode data can be retrieved in 2 lines of code.

Fault Tolerance

Null checking
Automatic checking, correction addition of checksums such as GTIN checksums for UPC-A and UPC-E barcodes
Aware of format lengths and will zero pad numbers to ensure valid barcodes are generated
A detailed Exception model comprising of 7 custom exception types which guides developers to solve critical issues giving detailed error messages.

Easy Encoding

Encodes text, urls, binary data (byte[], streams) and numbers depending on format support.
Static BarcodeWriter class makes creating a barcode image a 1 line code task.

Detailed Style and Layout Control

A LINQ style Fluent API for the GeneratedBarcode class allows for inline barcode styling including:

Resizing while automatically keeping valid barcode proportions.
Add margins / borders
Check final image dimensions
Recoloring barcodes and their backgrounds
Verify barcodes are readable after styling using a single method call
Add text annotations or print the barcode values automatically above or below any barcode using any installed typeface. Features automatic text sizing and positioning.
