Originally developed by Forethought, who Microsoft bought out, PPT is the worlds most popular presentation file format. It is a very powerful tool that you can use to create presentations that include pictures, graphs, text and many other objects. Many businesses and students that have to present something will almost always do their presentation using Microsoft PowerPoint.
A large part of any presentation is how the text enters, appears and exits the screen. Entrance, emphasis, and exit of elements on a slide itself are controlled by what PowerPoint calls Custom Animations Transitions. These can be animated in a variety of ways. For example you can customise the animation to create small story boards by animating pictures to enter, exit or move. With different type of callouts, speech bubbles with edited text can be sent on and off to create speech. The overall design of a presentation can dictate how all the other slides appear and operate, this is called a master slide. Everything from design to the text on the slide can be edited using a primitive outliner.
SWF files are often pronounced Swiff files, they were developed by Macromedia which is now owned by Adobe. A SWF file is a small file that displays animated vector graphics. It can also contain text as well as raster vector graphics. It can be played in Web browsers that has the Flash plug-in installed.
SWF files are stored in files with the extension .swf and currently for historical reasons the MIME type is application/x-shockwave-flash. SWF files are binary files stored as 8-bit bytes. The latest version of SWF is SWF10. According to the Adobe development center this specification expands text capabilities with support for bidirectional text and complex scripts with the new DefineFont4 tag. The DefineBitsJPEG4 tag allows embedding JPEG images that have an alpha channel for opacity and also a smoothing filter. Adobe are always looking to enhance the SWF file format.
