Content APIs
The Aspose.Slides for .NET API gives you the ability to access, modify, or create almost any presentation content.

Master Slides: Access and modify presentation master slides to determine the normal slide layout
Regular slides: Access and modify existing slides or create new slide types.
Cloning/copying slides: cloning or copying within a presentation or from other presentations
Fill and text area: Access from an existing presentation or create slides with areas for entering text from scratch
Headers and footers: The API supports handling headers and footers in slides
Notes in slides: Add notes to slides or access and modify notes associated with a slide
Find a shape: Find shapes on any slide using the alternate text associated with a shape
Background: The API supports working with the background associated with the master slide or with the normal slide
Test blocks: create text blocks from scratch or access and modify text in blocks without loss in formatting
Shapes : Create or modify the following shapes
- Rectangles
- Polygons
- Elips
- Grouped shapes
- Auto Shapes
Shape Series: Although the API supports a certain number of shapes, if a shape is not supported, use the serialization method by which the shape can be serialized from an existing slide.
Scope:
- Picture frame
- Audio Frame – Audio files linked or embedded in a slide via an audio frame
- Video Frames
- OLE Frame – OLE frames are managed through the use of OLE frames
- Text frames – text associated with any shape can be accessed through a text frame belonging to the shape
Tables: API supports working with tables in slides
Text Scanning: The built-in scanning method is used to scan text at the slide level or at the level of the entire presentation
Animation: Shapes can be animated.
Slideshow: Slideshow and Slide Transit are supported.

PowerPoint Formatting API Features
The API supports formatting text and shapes in a slide in a presentation document. Text is formatted using paragraphs and snippets for each text frame. Text frames associated with shapes are the basic elements of a slide.

Advanced Security
The Aspose.Slides for .NET API provides the ability to close a presentation file to protect its contents from changes. Password protection of the presentation file is also supported, including protection of the PDF file after conversion to it. And one more thing: you can set read-only access for the generated presentation and for the document properties.

Microsoft Office automation is no longer needed!
Aspose.Slides for .NET is built using managed code that does not require Microsoft Office or Microsoft PowerPoint installed on your computer in order to work with PowerPoint documents. It’s a great alternative to automation from Microsoft Office in terms of supported features, security, stability, scalability, speed, and cost.
