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:
' ocrTesseract.Configuration.TesseractVersion = TesseractVersion.Tesseract5;

Private ocrInput = New OcrInput()
ocrInput.LoadImage("images\image.png")
Dim ocrResult = ocrTesseract.Read(ocrInput)
Console.WriteLine(ocrResult.Text)

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 language 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 line initializes an instance of IronTesseract, a class provided by the IronOCR library. The new object, ocrTesseract, will perform Optical Character Recognition (OCR) on images.

Next, an OcrInput object, ocrInput, is created to hold the image or images for OCR processing. The using keyword ensures ocrInput is automatically disposed of when no longer needed, conserving resources.

This line loads an image file at "images\image.png" into ocrInput. This image will be the target for OCR processing.

Here, the OCR operation is performed. The Read method of ocrTesseract processes the loaded image in ocrInput and returns an OcrResult object, ocrResult, which contains the recognized text.

Finally, this line prints the extracted text to the console by accessing the Text property of ocrResult.
