PPTX to HTML Conversion with Image and Css styles in Seperate folder

Aspose.Slides Product Family
1

Hi Team,

I am new to Aspose library. I have the requirement in .net platform to convert .pptx to .html and that too in the separate html page per slide. which i was able to achieve.As per the my understanding , what ever may be images in the pptx will be encrypted and using the same image in the HTML. But my requirement is that when converting .pptx to .html , there should be separate folder structure for the image and css style besides the html files. Is it possible through the Aspose library .Your support will be appreciate.

Regards,
Vishnu

@visuc9,

I have shared code snippet below. This will help you to achieve your requirements. Please share feedback with us if there is still an issue.

class ExternalResourcesHtmlController : IHtmlFormattingController, ILinkEmbedController
{
const string Header = “\n” +
“\n” +
“\n” +
“<meta http-equiv=“Content-Type” content=“text/html; charset=UTF-8”>\n” +
“<meta http-equiv=“X-UA-Compatible” content=“IE=11”>\n” +
“”;

const string UrlTemplate = @"www.example.com/resources/resource{0}.{1}";

private readonly ResponsiveHtmlController m_controller = new ResponsiveHtmlController();
private readonly Dictionary<int, string> m_resourceUrls = new Dictionary<int, string>();

public void WriteDocumentStart(IHtmlGenerator generator, IPresentation presentation)
{
    generator.AddHtml(Header);
}

void IHtmlFormattingController.WriteDocumentEnd(IHtmlGenerator generator, IPresentation presentation)
{
    ((IHtmlFormattingController) m_controller).WriteDocumentEnd(generator, presentation);
}

void IHtmlFormattingController.WriteSlideStart(IHtmlGenerator generator, ISlide slide)
{
    ((IHtmlFormattingController) m_controller).WriteSlideStart(generator, slide);
}

void IHtmlFormattingController.WriteSlideEnd(IHtmlGenerator generator, ISlide slide)
{
    ((IHtmlFormattingController) m_controller).WriteSlideEnd(generator, slide);
}

void IHtmlFormattingController.WriteShapeStart(IHtmlGenerator generator, IShape shape)
{
    ((IHtmlFormattingController) m_controller).WriteShapeStart(generator, shape);
}

void IHtmlFormattingController.WriteShapeEnd(IHtmlGenerator generator, IShape shape)
{
    ((IHtmlFormattingController) m_controller).WriteShapeEnd(generator, shape);
}

public LinkEmbedDecision GetObjectStoringLocation(
    int id,
    byte[] entityData,
    string semanticName,
    string contentType,
    string recomendedExtension)
{

    switch (contentType)
    {
        case "image/svg+xml":
        {
            return LinkEmbedDecision.Embed;
        }
        default:
        {
            string url = string.Format(UrlTemplate, id, recomendedExtension);
            m_resourceUrls.Add(id, url);
            return LinkEmbedDecision.Link;
        }
    }
}

public string GetUrl(int id, int referrer)
{
    return m_resourceUrls[id];
}

public void SaveExternal(int id, byte[] entityData)
{
    string fileName = Path.GetFileName(m_resourceUrls[id]);
            
    // upload to the correct web folder or any other actions required to store resources
            
    // example: simply store in the same folder
    // File.WriteAllBytes(fileName, entityData);
}

}

…

using (Presentation pres = new Presentation(“pres.pptx”))
{
ExternalResourcesHtmlController externalResourcesHtmlController = new ExternalResourcesHtmlController();

HtmlOptions htmlOptionsEmbed = new HtmlOptions(externalResourcesHtmlController)
{
    HtmlFormatter = HtmlFormatter.CreateCustomFormatter(externalResourcesHtmlController)
};

pres.Save("pres.html", SaveFormat.Html, htmlOptionsEmbed);

}
