该代码示例演示了如何使用 IronTesseract OCR 引擎从照片中提取文本并分析特定区域。
using IronOcr;
using IronSoftware.Drawing;
using System;
// Instantiate OCR engine
var ocr = new IronTesseract();
using var inputPhoto = new OcrInput();
inputPhoto.LoadImageFrame("ocr.tiff", 0);
// Read photo
OcrPhotoResult result = ocr.ReadPhoto(inputPhoto);
// Index number refer to region order in the page
int number = result.TextRegions[0].PageNumber;
// Extract the text in the first region
string textinregion = result.TextRegions[0].TextInRegion;
//Extract the co-ordinates of the first text region
Rectangle region = result.TextRegions[0].Region;
var output = $"Text in First Region: {textinregion}\n"
+ $"Text Region:\n"
+ $"Starting X: {region.X}\n"
+ $"Starting Y: {region.Y}\n"
+ $"Region Width: {region.Width}\n"
+ $"Region Height: {region.Height}\n"
+ $"Result Confidence: {result.Confidence}\n\n"
+ $"Full Scnned Photo Text: {result.Text}";
Console.WriteLine(output);
