Installation

IronQR Library

Installing the IronQR library is quick and easy. You can install the package using the following command:

PM > Install-Package IronQR

Install-Package IronQR

Alternatively, download directly from the official IronQR NuGet website.

Once installed, you can get started by adding using IronQR; to the top of your C# code.

IronQR.Slim Library

The IronQR.Slim contains both QR Generation and basic QR Reading capabilities. The IronQR package provides advanced custom Machine Learning Models and adapters to use it with IronQR.Slim. If you prefer to use IronQR without the increased package size and improved accuracy of the ML model, you can also use IronQR.Slim alone.

This choice will not affect generating/writing QR Codes, but note that reading will not utilize the advanced detection model. You can use the following command to install just the basic Slim version:

PM > Install-Package IronQR.Slim

Install-Package IronQR.Slim

Code Examples

Generate QR Code Example

using IronQr;
using IronSoftware.Drawing;

// Create a QR Code object
QrCode myQr = QrWriter.Write("hello world");

// Save QR Code as a Bitmap
AnyBitmap qrImage = myQr.Save();

// Save QR Code Bitmap as File
qrImage.SaveAs("qr.png");

using IronQr;
using IronSoftware.Drawing;

// Create a QR Code object
QrCode myQr = QrWriter.Write("hello world");

// Save QR Code as a Bitmap
AnyBitmap qrImage = myQr.Save();

// Save QR Code Bitmap as File
qrImage.SaveAs("qr.png");

Imports IronQr
Imports IronSoftware.Drawing

' Create a QR Code object
Dim myQr As QrCode = QrWriter.Write("hello world")

' Save QR Code as a Bitmap
Dim qrImage As AnyBitmap = myQr.Save()

' Save QR Code Bitmap as File
qrImage.SaveAs("qr.png")

Imports IronQr
Imports IronSoftware.Drawing

' Create a QR Code object
Dim myQr As QrCode = QrWriter.Write("hello world")

' Save QR Code as a Bitmap
Dim qrImage As AnyBitmap = myQr.Save()

' Save QR Code Bitmap as File
qrImage.SaveAs("qr.png")

Read QR Code Example

using IronQr;
using IronSoftware.Drawing;
using System.Collections.Generic;

// Open the asset to read a QR Code from
var inputBmp = AnyBitmap.FromFile("IMAGE_TO_READ.png");

// Load the asset into QrImageInput
QrImageInput imageInput = new QrImageInput(inputBmp);

// Create a QR Reader object
QrReader reader = new QrReader();

// Read the Input an get all embedded QR Codes
IEnumerable<QrResult> results = reader.Read(imageInput);

using IronQr;
using IronSoftware.Drawing;
using System.Collections.Generic;

// Open the asset to read a QR Code from
var inputBmp = AnyBitmap.FromFile("IMAGE_TO_READ.png");

// Load the asset into QrImageInput
QrImageInput imageInput = new QrImageInput(inputBmp);

// Create a QR Reader object
QrReader reader = new QrReader();

// Read the Input an get all embedded QR Codes
IEnumerable<QrResult> results = reader.Read(imageInput);

Imports IronQr
Imports IronSoftware.Drawing
Imports System.Collections.Generic

' Open the asset to read a QR Code from
Dim inputBmp = AnyBitmap.FromFile("IMAGE_TO_READ.png")

' Load the asset into QrImageInput
Dim imageInput As New QrImageInput(inputBmp)

' Create a QR Reader object
Dim reader As New QrReader()

' Read the Input an get all embedded QR Codes
Dim results As IEnumerable(Of QrResult) = reader.Read(imageInput)

Imports IronQr
Imports IronSoftware.Drawing
Imports System.Collections.Generic

' Open the asset to read a QR Code from
Dim inputBmp = AnyBitmap.FromFile("IMAGE_TO_READ.png")

' Load the asset into QrImageInput
Dim imageInput As New QrImageInput(inputBmp)

' Create a QR Reader object
Dim reader As New QrReader()

' Read the Input an get all embedded QR Codes
Dim results As IEnumerable(Of QrResult) = reader.Read(imageInput)
