Render hidden pages

Hidden pages are not rendered by default. In order to include them into the rendering GroupDocs.Viewer provides setRenderHiddenPages() property of the HtmlViewOptions, JpgViewOptions, PngViewOptions or PdfViewOptions class to true as shown in the example below.

This feature is supported for:

• Diagrams with hidden pages
• Presentations with hidden slides
• Spreadsheets with hidden worksheets

The following code sample shows how to render hidden pages.

    try (Viewer viewer = new Viewer("sample.pptx")) {
        HtmlViewOptions viewOptions = HtmlViewOptions.forEmbeddedResources();
        viewOptions.setRenderHiddenPages(true);
        viewer.view(viewOptions);
    }
