Summary | Specifies the field of view of a QuickTime VR movie. | ||||||
Introduced | 1.0 | ||||||
Changes | This property was deprecated in version 8.1.0 due to the retirement of the QuickTime player implementation. In order to support 64-bit on Mac we have been required to switch to using AVFoundation on Mac, which does not support QTVR. In addition, the Windows player object is now based on DirectShow, as Apple have dropped support for the QuickTime libraries previously used. | ||||||

Description | Use the zoom property to find out how much of a QuickTime VR movie the user can see at one time. The user can change the field of view of a QuickTime VR movie using the navigational controls in the player; a handler can change the view by setting the player's zoom property. The zoom specifies the angle of the viewer's field of view, in degrees. (Think of a camera with a zoom lens.) As the zoom increases, more of the scene can be seen. As the zoom decreases, the edges of the scene are no longer visible, but the center of the scene is shown in greater detail. A zoom of zero corresponds to the closest detailed view of a single point; a zoom of 90 corresponds to a wide-angle view of the scene. The zoom is limited by the player's constraints property. If you specify a zoom greater than the range permitted by the constraints, the zoom is set to the highest permitted value. If you specify a zoom less than the range permitted by the constraints, the zoom is set to the lowest permitted value. If the player does not contain a QuickTime VR movie, its zoom property is zero. | ||||||
