I need to import text from HTML to PPtx using asp.net.
I used AddFromHtml method to add style and text into slide. Color is working fine but background-color and bullet is not working. Please let me know by which way I can implement this.
For example HTML string: "

  • ABC
"

I am using version of aspose.slide : 17.11.0

@megham,

I have created an HTML file based on sample image you have provided and it has this HTML view. Please note that Aspose.Slides support only text related tags. In your HTML view, the text, “xyz” is highlighted. Only this highlighted text color is not getting imported in Aspose.Slides paragraph. There is no issue with bullets import as well. Can you please confirm, if this is the only issue occurring on your end.

@megham,

I have used following sample code on my end using Aspose.Slides for .NET 18.1. Can you please try using the HTML file that I have shared with you and provide the generated presentation file using following code on your end.

public static void ImportHMTL()
{
    String path = @"C:\Users\Muhammad\Downloads\testdoc\";
    using (Presentation presentation = new Presentation())
    {
        // Get the first slide
        ISlide slide = presentation.Slides[0];
        // Add an autoshape of type line
        Aspose.Slides.IAutoShape ashape = slide.Shapes.AddAutoShape(ShapeType.Rectangle, 10, 10, 300, 300);
        ashape.FillFormat.FillType = FillType.Solid;
        ashape.FillFormat.SolidFillColor.Color = Color.Gray;

        // Adding text frame to the shape
        ashape.AddTextFrame("");

        // Clearing all paragraphs in added text frame
        ashape.TextFrame.Paragraphs.Clear();

        // Loading the HTML file using stream reader
        TextReader tr = new StreamReader(path + "testdoc.html");

        // Adding text from HTML stream reader in text frame
        ashape.TextFrame.Paragraphs.AddFromHtml(tr.ReadToEnd());


        presentation.Save(path+"Saved.pptx", Aspose.Slides.Export.SaveFormat.Pptx);

    }
}

Please also share the Operating system and environment details used on your end.

It does not matter if you add existing shape text frame or create a new shape with text frame. If you still find issue using shared HTML file and above code sample then please provide a working sample project and generated presentation for reference.
