Whilst evaluating Aspose.Pdf 6.2.0 for .NET, I found that adding text to PDF documents with 16 pages appears to be very slow.
Below is the code I am using and attached is the PDF:
Console.WriteLine("{0:HH:mm:ss} Started", DateTime.Now);
Document document = new Document(“Rhubarb.pdf”);
Page page = document.Pages[1];
TextBuilder pdfPageTextBuilder = new TextBuilder(page);
TextState textState = new TextState();
textState.FontSize = 10f;
textState.Font = FontRepository.FindFont(“Arial”);
textState.ForegroundColor = System.Drawing.Color.Black;
TextParagraph textParagraph = new TextParagraph();
textParagraph.AppendLine(“Test”, textState);
textParagraph.Position = new Position(50, 50);
pdfPageTextBuilder.AppendParagraph(textParagraph);
document.Save(“Populated.pdf”);
Console.WriteLine("{0:HH:mm:ss} Finished", DateTime.Now);
Console.ReadLine();
When I run this on my laptop, I see the following:
16:27:01 Started
16:27:21 Finished
So it appears to be taking 20 seconds just to add a single text item. Doing the same using PDFSharp takes a fraction of a second.
Please can you explain how I can achieve what I want? I.e. a fast way of adding text to PDF documents with 16 pages or more.
