未處理的異常：System.Runtime.InteropServices.SEHException

File G7IUWBgksH related to Troubleshooting SEHException and AVX Support in IronOCR

這個問題通常會在使用較舊的 Xeon、Celeron、Pentium 或 Atom 處理器的機器上遇到，因為這些處理器缺乏 AVX 支援。

IronOcr 版本2022.8.7804新增了對非 AVX 處理器的支援，因此請升級至較後的版本。

// Example: Checking AVX support programmatically in C#
using System;

class ProcessorFeatures
{
    // Main method to check AVX support
    static void Main()
    {
        // Check if the machine's processor supports AVX
        if (IsAvxSupported())
        {
            Console.WriteLine("AVX is supported.");
        }
        else
        {
            Console.WriteLine("AVX is not supported. Consider updating IronOcr to the latest version that supports non-AVX processors.");
        }
    }

    // Function to determine if AVX is supported
    static bool IsAvxSupported()
    {
        return System.Runtime.Intrinsics.X86.Avx.IsSupported;
    }
}

// Example: Checking AVX support programmatically in C#
using System;

class ProcessorFeatures
{
    // Main method to check AVX support
    static void Main()
    {
        // Check if the machine's processor supports AVX
        if (IsAvxSupported())
        {
            Console.WriteLine("AVX is supported.");
        }
        else
        {
            Console.WriteLine("AVX is not supported. Consider updating IronOcr to the latest version that supports non-AVX processors.");
        }
    }

    // Function to determine if AVX is supported
    static bool IsAvxSupported()
    {
        return System.Runtime.Intrinsics.X86.Avx.IsSupported;
    }
}

' Example: Checking AVX support programmatically in C#
Imports System

Friend Class ProcessorFeatures
	' Main method to check AVX support
	Shared Sub Main()
		' Check if the machine's processor supports AVX
		If IsAvxSupported() Then
			Console.WriteLine("AVX is supported.")
		Else
			Console.WriteLine("AVX is not supported. Consider updating IronOcr to the latest version that supports non-AVX processors.")
		End If
	End Sub

	' Function to determine if AVX is supported

在此範例程式碼中，我們使用 System.Runtime.Intrinsics.X86.Avx.IsSupported 屬性來判斷處理器是否支援 AVX 指令。如果不支援 AVX，建議您確保使用的 IronOcr 版本包含對非 AVX 處理器的支援。
