# .NET MRZ Scanner SDK
The .NET Machine-readable Zone (MRZ) Scanner SDK is a C# wrapper for [Dynamsoft Label Recognizer](https://www.dynamsoft.com/label-recognition/overview/?utm_content=nav-products), supporting **x64 Windows**, **x64 Linux**, **Android** and **iOS**. It is used to recognize MRZ information from **passport**, **Visa**, **ID card** and **travel documents**.
## License Activation
Click [here](https://www.dynamsoft.com/customer/license/trialLicense/?product=dcv&package=cross-platform) to get a trial license key.
## Supported Platforms
- Windows (x64)
- Linux (x64)
- Android
- iOS
## API
- `public static void InitLicense(string license)`: Initialize the license. It must be called before creating the MRZ scanner object.
- `public static MrzScanner Create()`: Create the MRZ scanner object.
- `public Result[]? DetectFile(string filename)`: Detect MRZ from an image file.
- `public Result[]? DetectBuffer(byte[] buffer, int width, int height, int stride, ImagePixelFormat format)`: Detect MRZ from a buffer.
- `public static string? GetVersionInfo()`: Get SDK version number.
## Usage
- Set the license key:
```csharp
MrzScanner.InitLicense("LICENSE-KEY");
```
- Initialize the MRZ scanner object:
```csharp
MrzScanner scanner = MrzScanner.Create();
```
- Detect MRZ from an image file:
```csharp
Result[]? result = scanner.DetectFile(filename);
```
- Detect MRZ from a buffer:
```csharp
Result[]? result = scanner.DetectBuffer(bytes, width, height, stride, MrzScanner.ImagePixelFormat.IPF_RGB_888);
```
- Get SDK version number:
```csharp
string? version = MrzScanner.GetVersionInfo();
```
- Parse the MRZ information:
```csharp
string[] lines = new string[_results.Length];
var index = 0;
foreach (Result result in _results)
{
lines[index++] = result.Text;
}
MrzResult info = MrzParser.Parse(lines);
```
## Quick Start
```csharp
using System;
using System.Runtime.InteropServices;
using Dynamsoft;
namespace Test
{
class Program
{
static void Main(string[] args)
{
MrzScanner.InitLicense("LICENSE-KEY");
Console.WriteLine("Version: " + MrzScanner.GetVersionInfo());
MrzScanner scanner = MrzScanner.Create();
MrzScanner.Result[]? results = scanner.DetectFile("1.png");
if (results != null)
{
foreach (MrzScanner.Result result in results)
{
Console.WriteLine(result.Text);
Console.WriteLine(result.Points[0] + ", " +result.Points[1] + ", " + result.Points[2] + ", " + result.Points[3] + ", " + result.Points[4] + ", " + result.Points[5] + ", " + result.Points[6] + ", " + result.Points[7]);
}
}
}
}
}
```
## Example
- [Command-line MRZ Scanner](https://github.com/yushulx/dotnet-mrz-sdk/tree/main/example/command-line) (**Windows & Linux**)
```bash
# DEBUG
dotnet run
# RELEASE
dotnet run --configuration Release
```
- [Command-line MRZ Scanner with OpenCVSharp Windows runtime](https://github.com/yushulx/dotnet-mrz-sdk/tree/main/example/command-line-cv). To make it work on Linux, you need to install [OpenCVSharp4.runtime.ubuntu.18.04-x64](https://www.nuget.org/packages/OpenCvSharp4.runtime.ubuntu.18.04-x64) package.
```bash
dotnet run
```
- [WinForms Desktop MRZ Scanner](https://github.com/yushulx/dotnet-mrz-sdk/tree/main/example/desktop-gui) (**Windows Only**)
```bash
dotnet run
```
- [.NET MAUI for Android and iOS](https://github.com/yushulx/dotnet-mrz-sdk/tree/main/example/MauiAndroid)
## Building NuGet Package from Source Code
