Convert PowerPoint Presentations to SWF Flash in .NET

Convert Presentations to Flash

The Save method exposed by Presentation class can be used to convert the whole presentation into SWF document.  You can also include comments in generated SWF by using SWFOptions class and INotesCommentsLayoutingOptions interface. The following example shows how to convert a presentation into SWF document by using options provided by SWFOptions class.

// Instantiate a Presentation object that represents a presentation file
using (Presentation presentation = new Presentation("HelloWorld.pptx"))
{
    SwfOptions swfOptions = new SwfOptions();
    swfOptions.ViewerIncluded = false;


    INotesCommentsLayoutingOptions notesOptions = swfOptions.NotesCommentsLayouting;
    notesOptions.NotesPosition = NotesPositions.BottomFull;

    // Saving presentation and notes pages
    presentation.Save("SaveAsSwf_out.swf", SaveFormat.Swf, swfOptions);
    swfOptions.ViewerIncluded = true;
    presentation.Save("SaveNotes_out.swf", SaveFormat.Swf, swfOptions);
}

FAQ

Can I include hidden slides in the SWF?

Yes. Enable the ShowHiddenSlides option in SwfOptions. By default, hidden slides are not exported.

How can I control compression and the final SWF size?

Use the Compressed flag (enabled by default) and adjust JpegQuality to balance file size and image fidelity.

What is ‘ViewerIncluded’ for, and when should I disable it?

ViewerIncluded adds an embedded player UI (navigation controls, panels, search). Disable it if you plan to use your own player or need a bare SWF frame without UI.

What happens if a source font is missing on the export machine?

Aspose.Slides will substitute the font you specify via DefaultRegularFont in SwfOptions to avoid an unintended fallback.
