چگونه یک PII اتوماتیک یا خط لوله ویرایش کلمات کلیدی با .NET بسازیم

List<string> piiList = new List<string>(File.ReadAllLines("pii_keywords.txt"));
string[] files = Directory.GetFiles("./input", "*.png");

RecognitionSettings settings = new RecognitionSettings();
settings.Language = Language.English;
AsposeOcr ocr = new AsposeOcr();
foreach (string file in files)
{
    foreach (string pii in piiList)
    {
        bool found = ocr.ImageHasText(file, pii, settings);
        if (found)
        {
            // Proceed to redact in Step 3
        }
    }
}

// Example using System.Drawing to overlay black box (simplified)
using (var image = new Bitmap(file))
{
    using (var g = Graphics.FromImage(image))
    {
        // Locate/estimate bounding box for found term (requires mapping OCR region, see docs/API)
        // g.FillRectangle(Brushes.Black, x, y, width, height);
    }
    image.Save($"./redacted/redacted_{Path.GetFileName(file)}");
}

File.AppendAllText("redaction_log.csv", $"{file},{pii},redacted\n");

                        // Save redacted copy
                        image.Save($"./redacted/redacted_{Path.GetFileName(file)}");
                    }
                    File.AppendAllText("redaction_log.csv", $"{file},{pii},redacted\n");
