hi,
zhaochen_81:1. What is the different between document.ProcessParagraghs() and page.ProcessParagraphs()?
I have tested the scenario using Aspose.Pdf for .NET 11.0.0 and I am unable to notice any issue. As per my observations, the resultant file is properly being generated. For your reference, I have also attached the document generated over my end.zhaochen_81:2. If I use document.ProcessParagraphs(), the code will remain running and never come to an end.
zhaochen_81:1. Since I only add one page, I think there should be no difference between two methods.We are sorry for the confusion, ProcessParagraphs() method of Page class is internal method we will mark this private soon. It is recommend to use ProcessParagraphs() method of Document class.zhaochen_81:2. That is easy to reproduce this issue, only by increase for index to 20000 or more; Besides, this is a bad user experience since it will process for a very long time. And I want to know that if 20000 characters is a burden to HtmlFragment?I have tested the scenario using Aspose.Pdf for .NET 11.0.0 on Win7 64 bit with 8GB RAM and unable to replicate the issue. We will appreciate it if you please share some more details to replicate the issue.");Document pdf = new Document();
Aspose.Pdf.Page page = pdf.Pages.Add();
var builder = new StringBuilder();
builder.Append("");
for (int i = 0; i < 30000; i++)
{
builder.Append("A");
}
builder.Append("
var html = new HtmlFragment(builder.ToString());
page.Paragraphs.Add(html);
pdf.ProcessParagraphs();
pdf.Save(myDir + "HtmlFragmenttest.pdf");
We are sorry for the inconvenience caused.

Hi team,
We have tested with the new package 11.1.0 you said above, but the problem is still existing in our product, it hangs on step "document.ProcessParagraphs();". Can you please look at it again in your new build? It means a lot to us since the issue is really bad and urgent on our side.
Thanks,
Zhao
Hi Zhao,

pdf.Save(myDir + "HtmlFragmenttest.pdf");
Hi Tilal,
Thanks for checking, here is what we used to reproduc the issue, can you try this? you will find it hangs at step: document.ProcessParagraphs();
I have attached the file “test.txt”, which contains lots of characters, although in reality we may not be using as many characters as in this attachment in in our product, but we will definitely use many HtmlFragment, so this issue will happen frequently, can you try with it?
try
{
Console.WriteLine(DateTime.Now.ToString());
var pdfLicense = new License();
pdfLicense.SetLicense(“Aspose.Total.lic”);
Document document = new Document { PageInfo = { Width = PageSize.A4.Width } };
var page = document.Pages.Add();
Table pageTable = new Table();
page.Paragraphs.Add(pageTable);
var row = pageTable.Rows.Add();
var cell = row.Cells.Add();
string str = File.ReadAllText(@“C:\test.txt”);
var html = new HtmlFragment(str);
cell.Paragraphs.Add(html);
document.ProcessParagraphs();
document.Save(@“C:\TestPDF.pdf”);
Console.WriteLine(DateTime.Now.ToString());
Console.ReadLine();
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
Console.ReadLine();
}
Thanks,
Zhao
