# Image to Text in C#
This repository contains sample C# source code referenced in the tutorial documentation for **IronOCR**.
https://ironsoftware.com/csharp/ocr/
## Dependancies
The Iron OCR library for .Net
```
PM > Install-Package IronOcr
```
## Example 1
Example 1 explores the **AutoOcr** Class an shows that OCR can be performed in a single line of C# code in a .Net Project
This technique works for OCR on Images, Screenshots, Scans, Photographs and PDF documents.
## Example 2
Example 2 shows the **AdvancedOcr** Class.
It also demonstrated IronOCR key feature - it is highly successful in performing OCR on low quality input images and documents.
Even with skew, rotation. text distortion and digital noise, there is only a 0.9% drop in OCR accuracy and no major loss of speed for OCR.
## Example 3
Example 3 shows how to use a **System.Drawing.Rectangle** to perform OCR on a specified region ("crop-region") of a document.
## Example 4
Example 4 shows the use af an [OCR language pack](https://ironsoftware.com/csharp/ocr/languages/) to read Arabic text in C#.
```
PM> Install-Package IronOcr.Languages.Arabic
```
