探索IronOCR的許多其他功能——為您的所有OCR需求提供理想的程式庫！

文件型別支援

多頁/幀TIFF和GIF

輕鬆處理以TIFF和GIF格式儲存的多頁文件。 IronOcr在單次操作中閱讀所有頁面或幀，節省了您手動拆分文件的複雜性。

using IronOcr;

// Instantiate IronTesseract
IronTesseract ocrTesseract = new IronTesseract();

// Import TIFF/TIF
using var imageInput = new OcrImageInput("sample.tiff");

// Perform OCR
OcrResult ocrResult = ocrTesseract.Read(imageInput);

using IronOcr;

// Instantiate IronTesseract
IronTesseract ocrTesseract = new IronTesseract();

// Import TIFF/TIF
using var imageInput = new OcrImageInput("sample.tiff");

// Perform OCR
OcrResult ocrResult = ocrTesseract.Read(imageInput);

Imports IronOcr

' Instantiate IronTesseract
Dim ocrTesseract As New IronTesseract()

' Import TIFF/TIF
Using imageInput = New OcrImageInput("sample.tiff")

    ' Perform OCR
    Dim ocrResult As OcrResult = ocrTesseract.Read(imageInput)
End Using

PDF / PDF流

從PDF文件或記憶體流中準確地直接提取文字，輕鬆處理本地和掃描的（基於圖像的）PDF。

瞭解如何使用:在.NET C#中閱讀PDF

using IronOcr;

// Instantiate IronTesseract
IronTesseract ocrTesseract = new IronTesseract();

// Add PDF
using var pdfInput = new OcrPdfInput("sample.pdf");

// Perform OCR
OcrResult ocrResult = ocrTesseract.Read(pdfInput);

using IronOcr;

// Instantiate IronTesseract
IronTesseract ocrTesseract = new IronTesseract();

// Add PDF
using var pdfInput = new OcrPdfInput("sample.pdf");

// Perform OCR
OcrResult ocrResult = ocrTesseract.Read(pdfInput);

Imports IronOcr

' Instantiate IronTesseract
Dim ocrTesseract As New IronTesseract()

' Add PDF
Using pdfInput As New OcrPdfInput("sample.pdf")
    ' Perform OCR
    Dim ocrResult As OcrResult = ocrTesseract.Read(pdfInput)
End Using

圖像（jpg, png, bmp）

IronOCR支援所有標準圖像格式，如JPG, PNG和BMP。只需提供文件路徑，IronOCR將處理剩下的部分。

瞭解如何使用:在.NET C#中閱讀圖像

using IronOcr;

// Instantiate IronTesseract
IronTesseract ocrTesseract = new IronTesseract();

// Add image
using var imageInput = new OcrImageInput("Potter.png");

// Perform OCR
OcrResult ocrResult = ocrTesseract.Read(imageInput);

using IronOcr;

// Instantiate IronTesseract
IronTesseract ocrTesseract = new IronTesseract();

// Add image
using var imageInput = new OcrImageInput("Potter.png");

// Perform OCR
OcrResult ocrResult = ocrTesseract.Read(imageInput);

Imports IronOcr

' Instantiate IronTesseract
Dim ocrTesseract As New IronTesseract()

' Add image
Using imageInput = New OcrImageInput("Potter.png")
    ' Perform OCR
    Dim ocrResult As OcrResult = ocrTesseract.Read(imageInput)
End Using

性能提升器

多執行緒Tesseract OCR

構建具有完全支援並發處理的高度可擴展、響應快速的應用程式。安全地同時在不同執行緒中處理多個文件，以進行高性能的伺服器端部署。

瞭解如何使用:在C#中使用多執行緒Tesseract OCR

using IronOcr;

var ocrTesseract = new IronTesseract();
using var ocrInput = new OcrInput();
ocrInput.LoadPdf("sample.pdf");

// Image processing is automatically multi-threaded
ocrInput.Deskew();

// OCR reading is automatically multi-threaded too
var ocrResult = ocrTesseract.Read(ocrInput);

using IronOcr;

var ocrTesseract = new IronTesseract();
using var ocrInput = new OcrInput();
ocrInput.LoadPdf("sample.pdf");

// Image processing is automatically multi-threaded
ocrInput.Deskew();

// OCR reading is automatically multi-threaded too
var ocrResult = ocrTesseract.Read(ocrInput);

Imports IronOcr

Dim ocrTesseract = New IronTesseract()
Using ocrInput = New OcrInput()
    ocrInput.LoadPdf("sample.pdf")

    ' Image processing is automatically multi-threaded
    ocrInput.Deskew()

    ' OCR reading is automatically multi-threaded too
    Dim ocrResult = ocrTesseract.Read(ocrInput)
End Using

放棄令牌

控制長時間運行的OCR任務。使用放棄令牌可優雅地中止或取消過程，這對於管理資源或實現使用者可取消的操作非常有用。

瞭解如何使用:C# Tesseract放棄令牌

using IronOcr;
using System.Threading;

// Opens a Large PDF which may need to be cancelled early
IronTesseract ocrTesseract = new IronTesseract() { Language = OcrLanguage.English };
using var ocrInput = new OcrInput();
ocrInput.LoadPdf("sample.pdf");

// Starts a read on the PDF using IronOCR
OcrReadTask ocrRead = ocrTesseract.ReadAsync(ocrInput);
Thread.Sleep(1000); // Time passes...

// Cancellation Example:
ocrRead.Cancel();
ocrRead.Wait();

using IronOcr;
using System.Threading;

// Opens a Large PDF which may need to be cancelled early
IronTesseract ocrTesseract = new IronTesseract() { Language = OcrLanguage.English };
using var ocrInput = new OcrInput();
ocrInput.LoadPdf("sample.pdf");

// Starts a read on the PDF using IronOCR
OcrReadTask ocrRead = ocrTesseract.ReadAsync(ocrInput);
Thread.Sleep(1000); // Time passes...

// Cancellation Example:
ocrRead.Cancel();
ocrRead.Wait();

Imports IronOcr
Imports System.Threading

' Opens a Large PDF which may need to be cancelled early
Dim ocrTesseract As New IronTesseract() With {.Language = OcrLanguage.English}
Using ocrInput As New OcrInput()
    ocrInput.LoadPdf("sample.pdf")

    ' Starts a read on the PDF using IronOCR
    Dim ocrRead As OcrReadTask = ocrTesseract.ReadAsync(ocrInput)
    Thread.Sleep(1000) ' Time passes...

    ' Cancellation Example:
    ocrRead.Cancel()
    ocrRead.Wait()
End Using

時間限制

防止您的應用程式在困難或損壞的文件上掛起。為任何OCR過程設置特定的時間限制，以確保更好的資源管理和系統穩定性。

瞭解如何使用:C# Tesseract時間限制

using IronOcr;

int cancel_time = 1000;

// Opens a Large PDF which may need to be cancelled early
IronTesseract ocrTesseract = new IronTesseract() { Language = OcrLanguage.English };
var ocrInput = new OcrInput();
ocrInput.LoadPdf("large-report.pdf");

// Starts a read on the PDF using IronOCR with specified cancel time
OcrReadTask ocrRead = ocrTesseract.ReadAsync(ocrInput, cancel_time);

using IronOcr;

int cancel_time = 1000;

// Opens a Large PDF which may need to be cancelled early
IronTesseract ocrTesseract = new IronTesseract() { Language = OcrLanguage.English };
var ocrInput = new OcrInput();
ocrInput.LoadPdf("large-report.pdf");

// Starts a read on the PDF using IronOCR with specified cancel time
OcrReadTask ocrRead = ocrTesseract.ReadAsync(ocrInput, cancel_time);

Imports IronOcr

Dim cancel_time As Integer = 1000

' Opens a Large PDF which may need to be cancelled early
Dim ocrTesseract As New IronTesseract() With {.Language = OcrLanguage.English}
Dim ocrInput = New OcrInput()
ocrInput.LoadPdf("large-report.pdf")

' Starts a read on the PDF using IronOCR with specified cancel time
Dim ocrRead As OcrReadTask = ocrTesseract.ReadAsync(ocrInput, cancel_time)

OCR過程跟踪

從0%到100%監控OCR操作的實時進度。這使你能夠使用進度條向使用者提供反饋或更好地估計大型工作的完成時間。

瞭解如何使用:在.NET C#中使用進程跟踪

using IronOcr;

var ocrTesseract = new IronTesseract();

// Subscribe to OcrProgress event
ocrTesseract.OcrProgress += (_, ocrProgressEventsArgs) =>
{
    Console.WriteLine("Progress(%) | Duration");
    Console.WriteLine("    " + ocrProgressEventsArgs.ProgressPercent + "%     | " + ocrProgressEventsArgs.Duration.TotalSeconds + "s");
};
using var input = new OcrInput();
input.LoadPdf("Experiences-in-Biodiversity-Research-A-Field-Course.pdf");
// Progress events will fire during the read operation
var result = ocrTesseract.Read(input);

using IronOcr;

var ocrTesseract = new IronTesseract();

// Subscribe to OcrProgress event
ocrTesseract.OcrProgress += (_, ocrProgressEventsArgs) =>
{
    Console.WriteLine("Progress(%) | Duration");
    Console.WriteLine("    " + ocrProgressEventsArgs.ProgressPercent + "%     | " + ocrProgressEventsArgs.Duration.TotalSeconds + "s");
};
using var input = new OcrInput();
input.LoadPdf("Experiences-in-Biodiversity-Research-A-Field-Course.pdf");
// Progress events will fire during the read operation
var result = ocrTesseract.Read(input);

Imports IronOcr

Dim ocrTesseract = New IronTesseract()

' Subscribe to OcrProgress event
AddHandler ocrTesseract.OcrProgress, Sub(_, ocrProgressEventsArgs)
    Console.WriteLine("Progress(%) | Duration")
    Console.WriteLine("    " & ocrProgressEventsArgs.ProgressPercent & "%     | " & ocrProgressEventsArgs.Duration.TotalSeconds & "s")
End Sub

Using input = New OcrInput()
    input.LoadPdf("Experiences-in-Biodiversity-Research-A-Field-Course.pdf")
    ' Progress events will fire during the read operation
    Dim result = ocrTesseract.Read(input)
End Using
