Abstract: A presentation application for masking portions of an object, such as the background of an image, is provided. The presentation application may provide a background removal tool that allows a user to define an initial point in the background of the object. The presentation application may establish an initial background color based on the initial point, and may compute and automatically adjust a color tolerance of the background color based on the distance that a user-controlled cursor is from the initial point. Using a seed-fill algorithm, the presentation application can select a contiguous portion of the object for masking that includes the initial point and surrounding pixels that are within the background color tolerance. To smoothen the edges of the contiguous portion, the presentation application can convert the portion to a vector graphic before making the object.

Abstract: A system for generating a structured file that includes all of the various media items need to play the corresponding media presentation is described. (Media items include, for example, images, movies, and audio files.) In one implementation, all of the various media items needed to support the presentation's playback may be collected, where after at least one of them is texturized. Texturing means converting a media item from a larger format to a smaller format. For example, a JPEG file (described in terms of scalable vector-based data) may be texturized to a PNG file (described in terms of pixel data). The items may then be organized in accordance with an event, and stored in a structured file. Once organized by event (e.g., presentation pause-points, frame transitions, effect transitions, input “click” and the like), the media items may be stored into the structured file, ready to playback the media presentation.

Abstract: A system in accordance with the present invention may include one or more processors, memory from which the processor may fetch instructions according to a clock operating at a frequency, a display device, and one or more programs stored in the memory, with instructions to create a structured file for storing data related to the media presentation, access the data related to the media presentation from the presentation application, organize the data related to the media presentation according to an event, and export the organized data related to the media presentation to the structured file. These instructions may also be executed as steps of a method and may be fetched during the execution of one or more programs stored in a computer-readable storage medium.

Abstract: A presentation application for animating objects placed on slides is provided. Using the presentation application, the user may add objects to slides of a presentation, and apply animations to the objects. The animations may include action builds (e.g., fundamental animations) and smart builds (e.g., complex combinations of action builds). The animations used in slides may be pre-processed, or may instead be rendered in real-time as the slides are being presented. The real-time rendering may be performed by graphics circuitry, such as the GPU of a video card.
