阿拉伯语、波斯语和乌尔都语语言包不能识别阿拉伯数字？

这是 Tesseract 语言包的一个已知问题。

以下语言包可能有助于解决阿拉伯数字的这一问题：

然后就可以使用 IronOCR 功能加载自定义语言包：

using IronOcr; var Ocr = new IronTesseract();
    Ocr.UseCustomTesseractLanguageFile("custom_tesseract_files/custom.traineddata");
    using (var Input = new OcrInput(@"images\image.png"))
    {
    var Result = Ocr.Read(Input);
    Console.WriteLine(Result.Text);
    }
using IronOcr; var Ocr = new IronTesseract();
    Ocr.UseCustomTesseractLanguageFile("custom_tesseract_files/custom.traineddata");
    using (var Input = new OcrInput(@"images\image.png"))
    {
    var Result = Ocr.Read(Input);
    Console.WriteLine(Result.Text);
    }
Imports IronOcr
Private Ocr = New IronTesseract()
	Ocr.UseCustomTesseractLanguageFile("custom_tesseract_files/custom.traineddata")
	Using Input = New OcrInput("images\image.png")
	Dim Result = Ocr.Read(Input)
	Console.WriteLine(Result.Text)
	End Using
