Add HTML content to slides
Overview
Bring HTML content into a presentation when your application already has formatted text or a fragment to reuse. The slide-level import can create slide objects for content such as text, lists, links, tables and pictures. Choose the import level that matches the fragment.
Usage example
This C# example imports a self-contained HTML fragment containing a heading and bold text through slide-level HTML import. It removes the initial blank slide, then saves import-html.pptx and a PNG preview of the imported slide. No website or external resource is fetched.
using System;
using System.Drawing;
using Aspose.Slides;
using Aspose.Slides.Export;
using var presentation = new Presentation();
var html = "<html><body><h1>Quarterly report</h1><p>Revenue is <b>growing</b>.</p></body></html>";
presentation.Slides.RemoveAt(0);
presentation.Slides.AddFromHtml(html);
presentation.Save("import-html.pptx", SaveFormat.Pptx);
using var image = presentation.Slides[0].GetImage(1f, 1f);
image.Save("import-html.png", Aspose.Slides.ImageFormat.Png);
FAQ
Which import path should I use for an HTML table?
Use slide-level HTML import when you need a table object. Paragraph-level import handles text and can flatten table cells into paragraphs.
Can I import an HTML fragment rather than a whole website?
Yes. Supply a self-contained HTML string or stream. Pick slide-level import when the fragment should become slide objects; text-frame import is useful for formatted text inside an existing shape.
What should I do with linked images or stylesheets?
Make resource locations resolvable through the import’s base URI and resource resolver, or supply self-contained content. Check the imported output rather than assuming browser layout or every web feature is preserved.
