A Viewer Preset is a collection of settings that determine how users view rich-media assets on their computer screens and mobile devices. If you are an administrator, you can create Viewer Presets. Settings are available for an array of viewer configuration options. For example, you can change the viewer display size or zoom behavior.
For instructions on creating and customizing your own HTML5 viewer presets, see the Adobe Scene7 HTML5 Viewer SDK available as a download from Adobe Developer Connection.
