The package creates slides for on-screen presentations based on PDF features without manipulating TeX's typesetting process. The presentation flow relies on PDF's abilities to display content step by step. Features include:
Free positioning of anything anywhere in painted areas on the slide, as well as in the main text block;
Numerous attributes to control the layout and the presentation flow, from TeX's primitive dimensions to the visibility of steps;
Feature inheritance from global to local settings, with intermediate types; Basic drawing facilities to produce symbols, e.g., for list items or buttons;
Colours, transparency, shades, and pictures;
Navigation with links, pop-up menus, and customizable bookmarks;
Easy switch between presentation and handout; and PDF transitions.
Besides the traditional documentation, the distribution includes visual documentation and six demo presentations ranging from geometric abstraction to classic style to silly video game.
