New Library Creates and Manipulates PowerPoint Files

With the release of Essential Studio^® 2015 Volume 1, Syncfusion introduced the beta version of Essential Presentation, a new .NET library that can read, write, convert, and create raster images from Microsoft PowerPoint files. It provides a rich object model similar to Syncfusion’s file format libraries: XlsIO, DocIO, and PDF. This library can be used with Windows Forms, WPF, ASP.NET, and ASP.NET MVC applications. As it does not depend on Microsoft Office or any other external software, this library can be used on the server side without any difficulty. Keep in mind that this version of Essential Presentation supports only PowerPoint 2007-2013 (.pptx) files.

Key features of Essential Presentation

• Opens and saves PowerPoint (.pptx) files from and to streams.
• Sends output to a client browser.
• Accesses and modifies a PowerPoint presentation’s document properties.
• Creates and manipulates charts within a PowerPoint file.
• Creates and manipulates bulleted lists, numbered lists, tables, shapes, pictures, etc.
• Exports a single slide or an entire PowerPoint presentation to PDF.
• Renders a slide or an entire presentation as an image.

Note: Since this version of Essential Presentation is in beta, it does not have some features found in Microsoft PowerPoint such as WordArt, SmartArt, slide notes, master-slide editing, animations, transitions, comments, headers, footers, OLE objects, handouts, equations, and built-in themes.

Experience the magic of Syncfusion’s C# PowerPoint Library. Witness your ideas come to life with its Microsoft PowerPoint-like editing, conversion, and formatting options.

How can I get started?

In order to create and modify a PowerPoint presentation, you need to know how the elements are organized in Essential Presentation’s document object model (DOM). The following figure illustrates this DOM.

• IPresentation – An instance of IPresentation represents an entire PowerPoint presentation file. It is the root element in Essential Presentation’s DOM. This presentation instance contains the slide collections present in the PowerPoint presentation file.
• ISlide – An instance of ISlide represents a single slide within a PowerPoint presentation, which in turn contains a collection of shapes. All the elements present within a slide are enclosed in a shape.
• IOfficeChart – IOfficeChart represents a chart present within a slide. Through this instance, you can customize the chart.
• ITable – An instance of ITable represents a table within a slide. A table instance contains a collection of rows.
• IRow – An IRow instance represents a single row in a table. Each row contains a collection of cells.
• ICell – An ICell instance represents a single cell within a row. A cell contains an instance of ITextBody, through which you can to add or modify the textual content of a slide.
• ITextBody – ITextBody represents a container for textual content. It can contain a collection of paragraphs.
• IParagraph – An IParagraph instance represents a paragraph. Paragraphs can only be added into text boxes and auto-shapes. A paragraph contains a collection of text parts.
• ITextPart – A text part is similar to <span> in HTML. An instance of ITextPart holds textual content of similar character-level formatting.
• IPicture – The IPicture interface represents a picture or image in a slide.
