Media Data Atom TypesPanorama TracksminPanThe minimum pan angle, in degrees. For a full panorama, the value of this field is usually 0.0.maxPanThe maximum pan angle, in degrees. For a full panorama, the value of this field is usually 360.0.minTiltThe minimum tilt angle, in degrees. For a high-resolution panorama, a typical value for this field is –42.5.maxTiltThe maximum tilt angle, in degrees. For a high-resolution panorama, a typical value for this field is +42.5.minFieldOfViewThe minimum vertical field of view, in degrees. For a high-resolution panorama, a typical value for thisfield is 5.0. The value in this field is 0 for the default minimum field of view, which is 5 percent of themaximum field of view.maxFieldOfViewThe maximum vertical field of view, in degrees. For a high-resolution panorama, a typical value for thisfield is 85.0. The value in this field is 0 for the default maximum field of view, which is maxTilt – minTilt.defaultPanThe default pan angle, in degrees.defaultTiltThe default tilt angle, in degrees.defaultFieldOfViewThe default vertical field of view, in degrees.imageSizeXThe width, in pixels, of the panorama stored in the highest resolution image track.imageSizeYThe height, in pixels, of the panorama stored in the highest resolution image track.imageNumFramesXThe number of frames into which the panoramic image is diced horizontally. The width of each frame(which is imageSizeX/imageNumFramesX) should be divisible by 4.imageNumFramesYThe number of frames into which the panoramic image is diced vertically. The height of each frame(which is imageSizeY/imageNumFramesY) should be divisible by 4.hotSpotSizeXThe width, in pixels, of the panorama stored in the highest resolution hot spot image track.hotSpotSizeYThe height, in pixels, of the panorama stored in the highest resolution hot spot image track.2012-08-14 | © 2004, 2012 Apple Inc.
