Step 1: Set up Your Environment

Begin by creating a working directory for your project. This is where your PowerPoint presentation and HTML output files will be stored.

string presentationName = Path.Combine(dataDir, "PresentationDemo.pptx");
string outFilePath = Path.Combine(dataDir, "HTMLConversion");

Step 2: Load the PowerPoint Presentation

Now, load the PowerPoint presentation using Aspose.Slides.

using (Presentation pres = new Presentation(presentationName))
{
    string outPath = dataDir;
}

Step 3: Configure HTML Conversion Options

Next, configure the HTML conversion options. You can specify various settings, such as whether to embed images in the HTML or save them separately.

Html5Options options = new Html5Options()
{
    // Force do not save images in HTML5 document
    EmbedImages = false,
    // Set the path for external images
    OutputPath = outPath
};

Step 4: Create an Output Directory

Create a directory to store the output HTML document.

if (!Directory.Exists(outFilePath))
{
    Directory.CreateDirectory(outFilePath);
}

Step 5: Save the Presentation as HTML

Finally, save the PowerPoint presentation as an HTML file using the configured options.
