Tesseract 5 for .NET

VB C#

using IronOcr;
using System;

var ocrTesseract = new IronTesseract();

// This is done by default and can be omitted:
// ocrTesseract.Configuration.TesseractVersion = TesseractVersion.Tesseract5;

using var ocrInput = new OcrInput();
ocrInput.LoadImage(@"images\image.png");
var ocrResult = ocrTesseract.Read(ocrInput);
Console.WriteLine(ocrResult.Text);

Imports IronOcr
Imports System

Private ocrTesseract = New IronTesseract()

' This is done by default and can be omitted:

Private ocrInput = New OcrInput()
ocrInput.LoadImage("images\image.png")

Tesseract 5 for .NET

With digital documents being the standard in modern enterprises and international business, having an OCR engine that depicts and extracts international languages is a key component to success in manipulating documents.

Tesseract 5 is the most advanced library known in any language at the time. However, it comes with a few caveats: It is not easily implemented and can be considered hard to use due to the higher barrier to entry.

However, IronOcr bridges that gap, allowing developers, both beginners and veterans, to utilize Tesseract 5 in a simple library. Furthermore, IronOCR is the only known .NET library for Tesseract 5 OCR, with cross-compatibility for .NET Framework, Standard, Core, Xamarin, and Mono.

5-Step Code to Use Tesseract 5

var ocrTesseract = new IronTesseract();
using var ocrInput = new OcrInput();
ocrInput.LoadImage(@"images\image.png");
var ocrResult = ocrTesseract.Read(ocrInput);
Console.WriteLine(ocrResult.Text);

This step-by-step code demonstrates how to implement IronOCR with Tesseract 5:

// Step 1: Initialize an instance of IronTesseract
// This creates a new instance of the IronTesseract class, which will be used 
// to perform Optical Character Recognition (OCR) on image files.
var ocrTesseract = new IronTesseract();

// Step 2: Create and manage an OcrInput object
// The using keyword ensures that the OcrInput object is properly disposed of 
// after use, thus managing resources efficiently.
using var ocrInput = new OcrInput();

// Step 3: Load an image into the OCR input object
// This line loads the image located at the specified path into the ocrInput 
// object, preparing it for OCR processing.
ocrInput.LoadImage(@"images\image.png");

// Step 4: Perform the OCR operation
// The Read method processes the image and returns an OcrResult object containing 
// the recognized text data from the image.
var ocrResult = ocrTesseract.Read(ocrInput);

// Step 5: Output the extracted text
// This line accesses the Text property of the OcrResult object, which contains 
// the recognized text, and prints it to the console.
Console.WriteLine(ocrResult.Text);

// Step 1: Initialize an instance of IronTesseract
// This creates a new instance of the IronTesseract class, which will be used 
// to perform Optical Character Recognition (OCR) on image files.
var ocrTesseract = new IronTesseract();

// Step 2: Create and manage an OcrInput object
// The using keyword ensures that the OcrInput object is properly disposed of 
// after use, thus managing resources efficiently.
using var ocrInput = new OcrInput();

// Step 3: Load an image into the OCR input object
// This line loads the image located at the specified path into the ocrInput 
// object, preparing it for OCR processing.
ocrInput.LoadImage(@"images\image.png");

// Step 4: Perform the OCR operation
// The Read method processes the image and returns an OcrResult object containing 
// the recognized text data from the image.
var ocrResult = ocrTesseract.Read(ocrInput);

// Step 5: Output the extracted text
// This line accesses the Text property of the OcrResult object, which contains 
// the recognized text, and prints it to the console.
Console.WriteLine(ocrResult.Text);

' Step 1: Initialize an instance of IronTesseract
' This creates a new instance of the IronTesseract class, which will be used 
' to perform Optical Character Recognition (OCR) on image files.
Dim ocrTesseract = New IronTesseract()

' Step 2: Create and manage an OcrInput object
' The using keyword ensures that the OcrInput object is properly disposed of 
' after use, thus managing resources efficiently.
Dim ocrInput As New OcrInput()

' Step 3: Load an image into the OCR input object
' This line loads the image located at the specified path into the ocrInput 
' object, preparing it for OCR processing.
ocrInput.LoadImage("images\image.png")

' Step 4: Perform the OCR operation
' The Read method processes the image and returns an OcrResult object containing 
' the recognized text data from the image.
Dim ocrResult = ocrTesseract.Read(ocrInput)

' Step 5: Output the extracted text
' This line accesses the Text property of the OcrResult object, which contains 
' the recognized text, and prints it to the console.
Console.WriteLine(ocrResult.Text)
