Custom Line Spacing Became Smaller after Converting PPTX to HTML5 in C#

Aspose.Slides Product Family

Hi,

We are using Aspose.Slides.NET.22.4.0 and we noticed that when having custom line spacing, the text does not look ok, as is in the input file, after converting the Pptx to Html5. This issue does not reproduce when converting to Html.

This is the code I am using:

        using (Presentation presentation = new Presentation(pptxInputFilePath))
        {
            HtmlOptions options = new HtmlOptions
            {
                HtmlFormatter = HtmlFormatter.CreateDocumentFormatter("", false)
            };
            presentation.Save($"{folderName}\\{fileName}_svg.html", SaveFormat.Html, options);


            presentation.Save($"{folderName}\\{fileName}_html5.html", SaveFormat.Html5, new Html5Options
            {
                AnimateShapes = false,
                AnimateTransitions = false
            });
        }

I am attaching the input file and the output files created after conversion to both Html5 and Html.

Thank you!

@SriranjiniNv,
The issue has a normal priority. The problem is waiting for an investigation. An issue resolution was preliminary estimated for 2022’Q4.

Hello,
this basically means that the new export option to HTML5 is unusable till end of this year - there are other issues reported on the same.

#7

@SriranjiniNv,
There is chance that some plans, roadmap or priorities will be changed, and the issue will be resolved sooner, but I don’t have any additional information yet.

#8

Hello,
are there any news on this issue? We cannot use latest version of the library till the HTML conversion issues are solved.

@SriranjiniNv,
The issue has not been resolved yet. Unfortunately, I don’t have any additional information.
