IronOCR 能讀取方程式嗎？

IronOCR 使用 Tesseract 4/5，開箱即用，讀取方程式的效果應該相當不錯，不過您可能需要嘗試更詳細的設定選項：

探索 Tesseract 配置變數

您也可以為 IronOCR 新增自訂語言套件：了解自訂語言套件

此外，還有一個 EQU 方程式偵測語言包： EQU 語言包

// C# Example to demonstrate reading equations using IronOCR

using IronOcr; // Import the IronOcr namespace

public class EquationOcrExample
{
    public void ReadEquations(string imagePath)
    {
        // Instantiate the IronTesseract object
        var Ocr = new IronTesseract();

        // Load the custom EQU language for better equation detection
        Ocr.Language = Ocr.Languages.Add("equ");

        // Read and OCR the image containing equations
        using (var Input = new OcrInput(imagePath))
        {
            // Extract OcrResult from the image
            var Result = Ocr.Read(Input);

            // Output the contents of the OCR result as text
            System.Console.WriteLine(Result.Text);
        }
    }
}

// C# Example to demonstrate reading equations using IronOCR

using IronOcr; // Import the IronOcr namespace

public class EquationOcrExample
{
    public void ReadEquations(string imagePath)
    {
        // Instantiate the IronTesseract object
        var Ocr = new IronTesseract();

        // Load the custom EQU language for better equation detection
        Ocr.Language = Ocr.Languages.Add("equ");

        // Read and OCR the image containing equations
        using (var Input = new OcrInput(imagePath))
        {
            // Extract OcrResult from the image
            var Result = Ocr.Read(Input);

            // Output the contents of the OCR result as text
            System.Console.WriteLine(Result.Text);
        }
    }
}

' C# Example to demonstrate reading equations using IronOCR

Imports IronOcr ' Import the IronOcr namespace

Public Class EquationOcrExample
	Public Sub ReadEquations(ByVal imagePath As String)
		' Instantiate the IronTesseract object
		Dim Ocr = New IronTesseract()

		' Load the custom EQU language for better equation detection
		Ocr.Language = Ocr.Languages.Add("equ")

		' Read and OCR the image containing equations
		Using Input = New OcrInput(imagePath)
			' Extract OcrResult from the image
			Dim Result = Ocr.Read(Input)

			' Output the contents of the OCR result as text
			System.Console.WriteLine(Result.Text)
		End Using
	End Sub
End Class

在上面的範例中，IronOCR 使用 Tesseract OCR 引擎從影像檔案中讀取方程式。為了提高識別精度，載入了自訂的方程式語言包 ( equ )。 ReadEquations方法接受包含方程式的圖像的檔案路徑，執行 OCR，並輸出識別出的文字。
