Media Data Atom TypesMovie MediakMovieMediaRegionAtomA number of child atoms, shown below, which describe how the Movie Media Handler should resize theembedded movie. If this atom is not present, the Movie Media Handler resizes the child movie tocompletely fill the containing track’s box.kMovieMediaSpatialAdjustmentThis atom contains an OSType that indicates how the embedded movie should be scaled to fitthe track box. If this atom is not present, the default value is kMovieMediaFitFill. These modesare all based on SMIL layout options.kMovieMediaFitClipIfNecessaryIf the media is larger than the track box, it will be clipped; if it is smaller, any additional area willbe transparent.kMovieMediaFitFillThe media will be scaled to completely fill the track box.kMovieMediaFitMeetThe media is proportionally scaled so that it is entirely visible in the track box and fills the largestarea possible without changing the aspect ratio.kMovieMediaFitSliceThe media is scaled proportionally so that the smaller dimension is completely visible.kMovieMediaFitScrollNot currently implemented. It currently has the same behavior askMovieMediaFitClipIfNecessary. When implemented, it will have the behavior describedin the SMIL specification for a scrolling layout element.kMovieMediaRectangleAtomFour child atoms that define a rectangle. Not all child atoms must be present: top and left must bothappear together, width and height must both appear together. The dimensions contained in this rectangleare used in place of the track box when applying the contents of the spatial adjustment atom. If the topand left are not specified, the top and left of the containing track’s box are used. If the width and height2012-08-14 | © 2004, 2012 Apple Inc. All Rights Reserved.314
