Newline characters ignored in PDF output with new engine

[formsbyair]

Hi guys

We're seeing another issue with PDF output using the new engine.

The code below correctly outputs text on multiple lines if useNewEngine is false. If useNewEngine is true then the output is all on one line.

Testing with 10.10.4

Code: Select all

var document = new Spire.Doc.Document(false);
//var document = new Spire.Doc.Document(true);  //newline characters ignored

var section = document.AddSection();

var table = section.AddTable(false);
table.PreferredWidth = new PreferredWidth(WidthType.Percentage, (short)100);

var row = table.AddRow(1);
var para = row.Cells[0].AddParagraph();
para.Text = "Testing\n\nNew line";

var docXStream = new MemoryStream();

document.SaveToStream(docXStream, Spire.Doc.FileFormat.PDF);

return docXStream.ToArray();

Thanks but version 10.11.0 doesn't appear to include SPIREDOC-8751 as per https://www.e-iceblue.com/Introduce/wor ... 3aWsnZBxD8

It does include a different issue that I reported separately as per post48767.html#p48767 => SPIREDOC-8540

Hello,

Thanks for your feedback.
I did more test again with theSpire.Doc 10.11.0, I created console project with .NetFramework4.8、console project with .NetCore 3.1 and console project with .Net6.0 to test your scenario on Win10, but I didn’t reproduce your issue. I attach my result pdf document. To help us reproduce your issue, please offer the following message, thanks for your assistance in advance.

1) Application type, such as Console App, .NET Framework 4.8.
2) Your test environment, such as OS info (E.g. Windows 7, 64-bit) and region setting (E.g. China, Chinese).

Here's the code I'm using to reproduce the problem (below)

I'm running a console app with .NET Framework 4.8 in Visual Studio 2022 on Windows 11 (22H2) in region New Zealand (English)

Code: Select all

            var document = new Spire.Doc.Document(true);  //newline characters ignored

            var section = document.AddSection();

            var table = section.AddTable(false);
            table.PreferredWidth = new PreferredWidth(WidthType.Percentage, (short)100);

            var row = table.AddRow(1);
            var para = row.Cells[0].AddParagraph();
            para.Text = "Testing\n\nNew line";

            document.SaveToFile("C:\\Users\\Shaun\\Documents\\Test.pdf", Spire.Doc.FileFormat.PDF);

Hello,

Thanks for your feedback.
After more tests, I figured out why I didn’t reproduce your scenario: in my code, before saving file to PDF file, I saved the file to word document. I put my test code below. However, I have communciated with our development team, they will investigate and fix it. Sorry for the inconvenience caused.

Code: Select all

  var document = new Spire.Doc.Document();  //newline characters ignored

            var section = document.AddSection();

            var table = section.AddTable(false);
            table.PreferredWidth = new PreferredWidth(WidthType.Percentage, (short)100);

            var row = table.AddRow(1);
            var para = row.Cells[0].AddParagraph();
            para.Text = "Testing\n\nNew line";

            //This line of extra code than yours
            document.SaveToFile(@"../../output/old_result.docx", FileFormat.Docx);
            document.SaveToFile(@"../../output/222222new_result.pdf",FileFormat.PDF);

Hello,

Greeting from E-iceblue.
For the issue with the number SPIREDOC-8751, I have some information to inform you:
The issue occurs when using “\n” as a line break in your code, according to the feedback from our development team, this issue currently will not be fixed currently due to you can using “\r\n” or “\r” as a line break to avoid this issue.

Yes, using \r instead of \n works fine with the new engine, thanks for your help.
