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 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.
