Osmose is a tool to prepare multimedia presentations. It has been tested under Mac OS X (Panther and Tiger), Linux, and Windows XP with Java 1.4.2. It allows you to print the presentations and to visualize them on the screen and on the Web in HTML (under Mac OS X, it is also easy to create PDF files from your presentations). Osmose is based on a research work that proposes a new way to create digital documents. Rather than WYSIWYG, it is a more complete way of working that articulates working on the content, adding multimedia files, and working on the style using a graphic theme.
PDFSlide is an application for displaying PDF-based presentations, such as those created by Beamer. It includes a presenter mode with current and next views. The timer view shows the current time and the elapsed presentation time. Apple Remote support is also included, which allows the presentation to be remotely controlled.
Aspose.Slides for Java is a Java component for manipulating PowerPoint presentations. It doesn't require PowerPoint and supports export to PDF, embedding and linking of audio and video frames, slide cloning, thumbnail generation, and presentation features, the ability to extract text from a presentation, and more.
