未處理的例外狀況：System.Runtime.InteropServices.SEHException

File G7IUWBgksH related to IronOCR 中 SEHException 及 AVX 支援的疑難排解

此問題常見於使用較舊款 Xeon、Celeron、Pentium 或 Atom 處理器且不支援 AVX 的電腦上。

IronOCR 版本 2022.8.7804 已新增對非 AVX 處理器的支援，請升級至較新版本。

// 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#

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 指令集。若系統不支援 AVX，建議確認您使用的 IronOCR 版本是否包含對非 AVX 處理器的支援。
