IronTesseract OCR 类为C#和.NET开发者提供了精细控制，以将OCR（图像和PDF到文本）功能添加到他们的应用程序中，并根据各自的具体用例微调性能。
通过设定变量，并结合实际案例，可以实现速度和准确性之间的完美平衡。 设置包括：DetectWhiteTextOnDarkBackgrounds 和 InputImageType。
using IronOcr;
using System;
var ocrTesseract = new IronTesseract();
using var ocrInput = new OcrInput();
ocrInput.LoadImage(@"images\image.png");
ocrInput.Deskew();
ocrInput.DeNoise();
ocrInput.Despeckle();
ocrInput.EnhanceResolution(225);
ocrInput.Sharpen();
ocrInput.Erode();
ocrInput.Dilate();
ocrInput.Scale(200);
var ocrResult = ocrTesseract.Read(ocrInput);
Console.WriteLine(ocrResult.Text);
