Hello,

Thanks for your inquiry.

I simulated a PDF file and tested the following code several times, but I did not reproduce your issue.

Code: Select all

            String input = @"SearchReplaceTemplate.pdf";
            PdfDocument doc = new PdfDocument();
            doc.LoadFromFile(input);

            PdfPageBase page = doc.Pages[0];
            PdfTextFindCollection collection = page.FindText("Spire.PDF for .NET", TextFindParameter.IgnoreCase);
            String newText = "Spire.PDF API";
            PdfTextFind find = collection.Finds[0];
            PdfBrush brush = new PdfSolidBrush(Color.DarkBlue);
            PdfTrueTypeFont font = new PdfTrueTypeFont(new Font("Arial", 15f, FontStyle.Bold));
            RectangleF rec = find.Bounds;
            page.Canvas.DrawRectangle(PdfBrushes.White, rec);
            page.Canvas.DrawString(newText, font, brush, rec);
            String result = "ReplaceFirstSearchedText_out.pdf";

            doc.SaveToFile(result);
