The Full Screen Preferences are used to control how the Full Screen Viewer behaves. The Full Screen viewer is displayed when you double-click on a thumbnail. The Full Screen Viewer cycles between all selected pictures (or all visible pictures if only one picture is selected).
Initial Size: This controls the initial size images are displayed. Once images are zoomed in/out, the current zoom ratio will stay in effect until the full screen viewer is closed.
Max. scaling factor %: This controls the maximum FotoAlbum will "stretch" a picture to try and fit the screen. This is only used when a picture is smaller than the screen and stretching may distort the look of the picture. 100% means no stretching will occur. The default is 200%.
Background color: The color displayed "behind" or around a picture.
Display Thumbnails: Whether the thumbnail bar is displayed by default. You can toggle the display of toolbar while viewing a picture full screen by using the <CTRL><T> shortcut.
Display captions: Whether the caption bar is displayed by default. You can also toggle the display of captions while in Full Screen mode by using the <CTRL><N> shortcut.
Display status bar: Controls whether the status bar is displayed. The status bar can also be toggled by using the <CTRL><Z> shortcut.
Average Colors: This option (if checked) performs a pixel averaging algorithm whenever images are resized. The effect of enabling this option is that images appear "smoother" but may take slightly longer to display.
Mouse wheel: This allows you to determine what the mouse wheel does when scrolled on the full screen viewer. You can make it either scroll between pictures or zoom in/out. Whatever option is chosen, holding down the shift key while scrolling the mouse wheel will perform the other choice.
Use Transitions: If this is checked, then the screen saver will use the chosen transition effect between each picture.
Effect: This controls which transition effect is used between pictures.
Delay: The amount of time the transition will take (0=fastest transition, 10=slowest transition).
Dissolve Prior Image: If checked, the prior image will "dissolve" away before the transition starts. The time required for the dissolve is in addition to the transition effect time.
Display Loading..: This controls whether FotoAlbum displays a little message "Loading.." on the screen whenever an image is being loaded.
Slide show delay: The number of seconds to pause between pictures when you start the slide show.
Cycle slide show: If this is checked, the slide show will run continuously (loop around). Otherwise it stops when it reaches the last picture.
