This version of Aspose.Slides for .NET introduces significant enhancements to presentation processing capabilities for C# developers. Take your presentations to the next level with version 24.4 of the .NET API.

Key Highlights

• A Modernized API: We have introduced a new and modern API, that will gradually replace dependencies on System.Drawing for a more streamlined development experience.
• ZIP64 Support: This update to the C# presentation API facilitates managing larger presentations with enhanced ZIP64 format support.
• Save PPTX as XML: You can now export presentations in the PowerPoint XML presentation format for broader compatibility.
• Detect Password-Protected Macros: With the latest API version, users can identify presentations with password-protected macros for improved security awareness.
• Improved Text Extraction: While converting presentations, our API ensures accurate text extraction from group shapes.
• Enhanced PDF Conversion: Developers can now experience better rendering of charts, tables, and text in exported PDFs.

Export Presentations in XML Format in C#

Using the newly added SaveFormat.Xml enum member, you can seamlessly convert Presentations to the XML file format. Please check out the following C# code example to know more:

using (Presentation pres = new Presentation())
{
    pres.Save("pres.xml", SaveFormat.Xml);
}

Introducsing ZIP64 Support

The PptxOptions.Zip64Mode property introduced in this release lets you determine whether the PowerPoint presentation is in ZIP64 format. The below-given C# code example explains more.

using (Presentation pres = new Presentation("demo.pptx"))
{
    pres.Save("demo-zip64.pptx", SaveFormat.Pptx, new PptxOptions()
    {
        Zip64Mode = Zip64Mode.Always
    });
}

Rasterize Unsupported Font Styling

We have introduced a new property named PdfOptions.RasterizeUnsupportedFontStyles in this update. The newly added property helps determine if the unsupported font (bold) styling must be rasterized as a bitmap and saved to a PDF document. The following code sample demonstrates the property usage.

using (Presentation pres = new Presentation())
{
    pres.Save("pres.pdf", SaveFormat.Pdf, new PdfOptions
    {
        RasterizeUnsupportedFontStyles = true
    });
}
