该代码示例演示了如何使用 IronTesseract OCR 引擎从截图中提取文本。
using IronOcr;
using System;
using System.Linq;
// Instantiate OCR engine
var ocr = new IronTesseract();
using var inputScreenshot = new OcrInput();
inputScreenshot.LoadImage("screenshotOCR.png");
// Perform OCR
OcrPhotoResult result = ocr.ReadScreenShot(inputScreenshot);
// Output screenshot information
Console.WriteLine(result.Text);
Console.WriteLine(result.TextRegions.First().Region.X);
Console.WriteLine(result.TextRegions.Last().Region.Width);
Console.WriteLine(result.Confidence);
Imports IronOcr

Imports System.Linq
' Instantiate OCR engine
Dim ocr = New IronTesseract()
Using inputScreenshot = New OcrInput()
inputScreenshot.LoadImage("screenshotOCR.png")
' Perform OCR
Dim result As OcrPhotoResult = ocr.ReadScreenShot(inputScreenshot)
' Output screenshot information
Console.WriteLine(result.Text)
Console.WriteLine(result.TextRegions.First().Region.X)
Console.WriteLine(result.TextRegions.Last().Region.Width)
Console.WriteLine(result.Confidence)
End UsingImports IronOcr
