Some Useful Examples and ScenariosOptimizing QuickTime VR Movies for Web PlaybackSample Atom Container for the QTVR FlattenerThe sample code in Listing 6-18 (page 368) creates an atom container and adds atoms to indicate an importpreview file for the flattener to use.Listing 6-18Specifying a preview file for the flattener to useBoolean yes = true;QTAtomContainer exportData;QTAtom parent;err = QTNewAtomContainer(&exportData);// create a parent for the other settings atomserr = QTInsertChild (exportData, kParentAtomIsContainer,QTVRFlattenerParentAtomType, 1, 0, 0, nil, &parent);// Add child atom to indicate we want to import the preview from a fileerr = QTInsertChild (exportData, parent, QTVRImportPreviewAtomType, 1, 0,sizeof (yes), &yes, nil);// Add child atom to tell which file to importerr = QTInsertChild (exportData, parent, QTVRImportSpecAtomType, 1, 0,sizeof (previewSpec), &previewSpec, nil);// Tell the export componentMovieExportSetSettingsFromAtomContainer (qtvrExport, exportData);Overriding the compression settings is a bit more complicated. You need to open a standard image compressiondialog component and make calls to obtain an atom container that you can then pass to the QTVR Flattenercomponent.Listing 6-19Overriding the compression settingsComponentInstance sc;QTAtomContainer compressorData;SCSpatialSettings ss;sc = OpenDefaultComponent(StandardCompressionType,StandardCompressionSubType);ss.codecType = kCinepakCodecType;ss.codec = nil;ss.depth = 0;ss.spatialQuality = codecHighQuality2012-08-14 | © 2004, 2012 Apple Inc.
