Load Presentation document with options Leave feedback

GroupDocs.Conversion provides PresentationLoadOptions to give you control over how Microsoft PowerPoint or Open Document presentation will be converted into the target format. The following options could be set:

Like many other Microsoft Office applications PowerPoint provides the “Comments” feature to simplify the presentation review. By default, comments are not included in a converted document. The CommentsPosition property controls this: PresentationCommentsPosition.None (the default) hides comments, while Bottom or Right prints them below or to the right of each slide. To print comments to the right of each slide, use the code snippet below:

Func<LoadContext, LoadOptions> getLoadOptions = loadContext => new PresentationLoadOptions
{
    CommentsPosition = PresentationCommentsPosition.Right
};
using (Converter converter = new Converter("sample.pptx", getLoadOptions))
{
    PdfConvertOptions options = new PdfConvertOptions();
    converter.Convert("converted.pdf", options);
}

Original PowerPoint presentations may use some specific and non-standard fonts for text formatting that are not available at the time of conversion. GroupDocs.Conversion for .NET allows you to provide substitutions for missing fonts by setting the FontSubstitues collection with original/substitute font pairs.

The following code snippet shows how to convert a PPTX presentation and specify substitutions for missing fonts:

Func<LoadContext, LoadOptions> getLoadOptions = loadContext => new PresentationLoadOptions
{
    DefaultFont = "Helvetica",
    FontSubstitutes = new List<FontSubstitute>
    {
       FontSubstitute.Create("Tahoma", "Arial"),
       FontSubstitute.Create("Times New Roman", "Arial"),
    }
};
using (Converter converter = new Converter("sample.pptx", getLoadOptions))
{
    PdfConvertOptions options = new PdfConvertOptions();
    converter.Convert("converted.pdf", options);
}

Just like you can show or hide slides in a Microsoft PowerPoint presentation manually, GroupDocs.Conversion for .NET allows displaying of the hidden slides in the converted document programmatically (by default all hidden slides are excluded from the converted document). You just have to set the ShowHiddenSlides property to true.

The following code snippet shows how to convert a PPTX presentation including the hidden slides:

Func<LoadContext, LoadOptions> getLoadOptions = loadContext => new PresentationLoadOptions
{
    ShowHiddenSlides = true
};
using (Converter converter = new Converter("sample.pptx", getLoadOptions))
{
    PdfConvertOptions options = new PdfConvertOptions();
    converter.Convert("converted.pdf", options);
}

In the context of presentations, external resources typically refer to elements or materials that are not directly embedded within the presentation file itself but are instead referenced or linked to enhance the presentation’s content or functionality. These external resources can include various types of content and tools that complement the presentation. Common external resources include images, audio, video, fonts, styles, data sources, and so on.

External resources are not loaded by default. Read the Skip loading of external resources article to learn how to allow trusted resources and decide per resource with a handler in GroupDocs.Conversion for .NET.
