IronOCR 能读取方程式吗？

IronOCR 使用 Tesseract 4/5，开箱即用，读取方程式的效果应该相当不错，不过您可能需要尝试一下更详细的配置选项：

探索 Tesseract 配置变量

您还可以向 IronOCR 添加自定义语言包：了解自定义语言包

此外，还有一个 EQU 方程式检测语言包： EQU 语言包

// 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

在上面的例子中，IronOCR 使用 Tesseract OCR 引擎从图像文件中读取方程式。为了提高识别精度，加载了自定义的方程式语言包 ( equ )。 ReadEquations方法接受包含方程式的图像的文件路径，执行 OCR，并输出识别出的文本。
