Optical Character Recognition (OCR) is a technology that transforms various document formats, including scanned paper documents, PDFs, digital file, or images of printed text taken with a digital camera, into editable and searchable machine-encoded text data.IronOCR is a great OCR engine library that offers powerful OCR functionalities to developers. In this article, we will explore how to perform OCR using IronOCR with code examples with OCR Software Demo.What is IronOCR?IronOCR is a powerful .NET library designed to facilitate optical character recognition (OCR) within C# and VB.NET applications. Leveraging advanced algorithms and machine learning techniques, IronOCR can accurately extract text and content from scanned PDF files, images, and PDFs, making it easier to process, search, and analyze such files programmatically.With its straightforward API and extensive features, developers can seamlessly integrate OCR capabilities into their applications to automate data extraction, document processing, data entry, and content management tasks. Whether you're working on business, with invoices, reports, automated data extraction, a searchable PDF, or any other text-rich documents, IronOCR offers a reliable solution to handle OCR requirements efficiently.Getting Started with IronOCRBefore diving into the code examples, you need to install IronOCR via NuGet Package Manager. You can install IronOCR by running the following command in the Package Manager Console:Install-Package IronOcrInstall-Package IronOcr'INSTANT VB TODO TASK: The following line uses invalid syntax:'Install-Package IronOcr$vbLabelText $csharpLabelPerforming OCR with IronOCRBasic Text RecognitionTo perform basic text recognition using IronOCR, you can use the following code snippet:using IronOcr;using System;IronTesseract ocrTesseract = new IronTesseract();using (OcrInput ocrInput = new OcrInput("ocr.png")){ OcrResult ocrResult = ocrTesseract.Read(ocrInput); string RecognizedText = ocrResult.Text; Console.WriteLine(RecognizedText);}using IronOcr;using System;IronTesseract ocrTesseract = new IronTesseract();using (OcrInput ocrInput = new OcrInput("ocr.png")){ OcrResult ocrResult = ocrTesseract.Read(ocrInput); string RecognizedText = ocrResult.Text; Console.WriteLine(RecognizedText);}Imports IronOcrImports SystemPrivate ocrTesseract As New IronTesseract()Using ocrInput As New OcrInput("ocr.png") Dim ocrResult As OcrResult = ocrTesseract.Read(ocrInput) Dim RecognizedText As String = ocrResult.Text Console.WriteLine(RecognizedText)End The detected barcode values are then printed to the console.IronOCR can also extract text from PDFs and scanned documents. Here's a code example that demonstrates how to extract text from a PDF file using IronOCR:using IronOcr;using System;var ocrTesseract = new IronTesseract();using var ocrInput = new OcrInput();// OCR entire documentocrInput.LoadPdf("Email_Report.pdf");int[] pages = { 1, 2, 3, 4, 5 };// Alternatively OCR selected page numbersocrInput.LoadPdfPages("example.pdf", pages, Password: "password");var ocrResult = ocrTesseract.Read(ocrInput);Console.WriteLine(ocrResult.Text);using IronOcr;using System;var ocrTesseract = new IronTesseract();using var ocrInput = new OcrInput();// OCR entire documentocrInput.LoadPdf("Email_Report.pdf");int[] pages = { 1, 2, 3, 4, 5 };// Alternatively OCR selected page numbersocrInput.LoadPdfPages("example.pdf", pages, Password: "password");var ocrResult = ocrTesseract.Read(ocrInput);Console.WriteLine(ocrResult.Text);Imports IronOcrImports SystemPrivate ocrTesseract = New IronTesseract()Private ocrInput = New OcrInput()' OCR entire documentocrInput.LoadPdf("Email_Report.pdf")Dim pages() As Integer = { 1, 2, 3, 4, 5 }' Alternatively OCR selected page numbersocrInput.LoadPdfPages("example.pdf", pages, Password:= "password")Dim ocrResult = ocrTesseract.Read(ocrInput)Console.WriteLine(ocrResult.Text)$vbLabelText $csharpLabelThe code uses IronOCR to perform OCR processing on a PDF document named "Email_Report.pdf". It can OCR the entire document using LoadPdf, or specific pages from "example.pdf" using LoadPdfPages with a password. The recognized text from the OCR operation is printed to the console.ConclusionIronOCR is a powerful .NET library that offers advanced OCR software capabilities, making it easy for developers to perform OCR tasks in their applications.

在當前的數位時代，將以圖像為基礎的內容轉換為易於閱讀、可編輯和可搜尋的文字。 這在像存檔紙質文件、從圖像中提取關鍵信息或數位化印刷材料等情境中特別重要。 光學字符識別(光學字符識別)技術提供了一種解決方案來自動化此轉換過程。 一個非常可靠且高效的工具是IronOCR，這是一個強大的 .NET OCR 庫。本文將解釋如何使用圖片轉換成文字IronOCR，並探討此轉換如何省時、減少錯誤以及簡化數據提取、歸檔和文件處理等流程。如何將圖片轉換為文字下載 C# 庫以進行 OCR 工作建立一個新的 `IronTesseract实例使用 ` 加載您的圖像OcrImageInput\使用`讀取圖像的內容OcrRead\將 OCR 結果導出到文字檔案中為什麼要將圖片轉換為文字？您可能想將圖片轉換為文字的原因有很多，包括：資料提取： 從掃描的文件和圖像中提取文字，用於歸檔或數據處理目的。編輯掃描內容： 編輯或更新先前已掃描文件中的文字，省去手動重新輸入內容的時間。提升可及性：將印刷材料轉換為數位文本，使其可供螢幕閱讀器或文字轉語音應用程式使用。自動化： 透過從發票、收據或名片中讀取文字來自動化資料輸入和處理。如何開始將圖像轉換為文字在我们探讨如何利用IronOCR强大的图像转文字功能从图像中提取文字之前，让我们先了解一下使用在线工具的一般分步流程，docsumo. 線上 OCR 工具是對於那些想要執行簡單或偶發 OCR 任務的人來說，是一個有用的選擇，因為它們不需要任何手動設置。 當然，如果您需要定期執行 OCR 任務，那麼擁有一個強大的 OCR 工具，例如 IronOCR，可能會對您更有幫助。導航至線上OCR工具上傳您的圖片並開始提取過程將結果數據下載為文本文件步驟一：導航至在線OCR工具要開始使用光學字符識別（OCR）技術從圖像文件中提取文字，我們首先需要導航到我們想要使用的在線圖像OCR工具。第 2 步：上傳您的圖片並開始提取過程現在，通過點擊“上傳文件”按鈕，我們可以上傳我們想要提取文字的圖像文件。 工具將立即開始處理圖像。步驟三：將結果數據下載為文本文件現在圖像已完成處理，我們可以將提取的文字下載為新的文本檔，以便進一步使用或操作。您也可以查看檔案，突出顯示各個部分以查看其內含的文字。 這可能特別有用，若您只想查看某些部分中的文本。 然後，您仍然可以將文本下載為文本檔、XLS 或 JSON。開始使用IronOCRIronOCR是一個多功能的 .NET 庫，允許您對圖像執行 OCR 操作。 提供廣泛功能，可以處理各種文件格式(例如 PNG、JPEG、TIFF 和 PDF)，進行圖像校正，掃描專業文件(護照、車牌等)，提供掃描文件的高級信息，轉換掃描文件，並突出顯示文字。安裝 IronOCR 函式庫在使用 IronOCR 開始讀取圖片之前，您需要先安裝它，如果您的專案中尚未安裝。 您可以在 Visual Studio 中使用 NuGet 輕鬆安裝 IronOCR。 打開 NuGet 套件管理器控制台，並運行以下命令：Install-Package IronOcr或者，您可以通過在解決方案包管理器頁面中搜索 IronOCR，來安裝 IronOCR。要在程式碼中使用IronOCR，請確保在程式碼頂部有適當的導入語句：using IronOcr;using IronOcr;Imports IronOcr$vbLabelText $csharpLabel將圖片轉換為文字：基礎範例首先，讓我們看看使用IronOCR進行基本的圖像轉文本範例。 這是任何 OCR 工具的核心功能，針對此示例，我們將使用我們用於在線工具的 PNG 文件。 在此範例中，我們首先實例化了IronTesseract類別並將其分配給變數 'ocr'。 然後我們使用OcrImageInputclass 以提供的圖像文件創建新的 OcrImageInput 對象。 最後，該讀取** 方法用於從圖像中讀取文本並返回一個[OcrResult](/csharp/ocr/object-reference/api/IronOcr.OcrResult.html)物件。 然後，我們可以存取擷取的文字並將其顯示在控制台上使用[ocrResult.Text**](/csharp/ocr/object-reference/api/IronOcr.OcrResult.html#IronOcr_OcrResult_Text).using IronOcr;IronTesseract ocr = new IronTesseract();using OcrImageInput

IronOcrPrivate ocr As New IronTesseract()Private OcrImageInput As usingPrivate ocrResult As OcrResult = ocr.Read(image)Console.WriteLine(ocrResult.Text)$vbLabelText $csharpLabel提高光學字符識別準確度可以通过优化图像和配置语言、图像分辨率以及图像中的噪声级别等选项来提高OCR性能。 以下是您可以如何微調OCR，以提高從需要通過以下方式提高質量的圖像中提取文本的準確性：去噪()**和銳化()方法：using IronOcrIronTesseract ocr = new IronTesseract();using OcrImageInput image = new OcrImageInput("example.png");image.DeNoise();image.Sharpen();OcrResult ocrResult = ocr.Read(image);Console.WriteLine(ocrResult.Text);using IronOcrIronTesseract ocr = new IronTesseract();using

Using$vbLabelText $csharpLabel匯出提取的文本現在我們知道圖像轉文字過程的基本知識，讓我們來看看如何將生成的文字匯出以供日後使用。 在這個例子中，我們將使用與之前相同的過程來加載圖像並掃描它。 然後，使用 File.WriteAllText("output.txt"，ocrResult.Text)我們創建一個名為 output.txt** 的新文本檔案，並將提取的文本保存到該檔案中。using IronOcr;IronTesseract ocr = new IronTesseract();using OcrImageInput image = new OcrImageInput("example.png");OcrResult ocrResult =
