Slide Show

Table of Contents

    Description

    The Slide Show collection reproduces the Ken Burns effect. Typically used with images, this effect automatically displays elements one at a time. For each element, a slow pan and zoom occurs, followed by a fading transition into the next element.

    Unlike with all other collections, the Slide Show collection cannot embed buttons and does not support the "pop out" effect. It is meant to be used solely as a display technique. If you are in need of a more interactive collection that can display one element at a time, see the Flip Chart collection.

    Collection appearance

    • Display duration: defines the time during which an item is visible
    • Transition duration: defines how much of the Display duration should remain when the fade effect begins. This fade effect is used to replace the current item with the next item.

    Animation effect

    • Type of zoom: indicate whether the zoom effect for each item should always be a zoom in, always be a zoom out, or randomly chosen from one item to the next.
    • Min possible zoom: indicate the smallest potential zoom factor for any item. A zoom factor of 1 is equivalent to no zoom at all. For each item, the actual zoom factor is randomly chosen between the min and max zoom factors set here.
    • Max possible zoom: indicate the largest potential zoom factor for any item. The max possible zoom factor for an item is 5 - that is, 5 times the original size. For each item, the actual zoom factor is randomly chosen between the min and max zoom factors set here.
    • Min possible translation: indicate the smallest possible distance the pan effect should travel from the center of each item. The min possible value is 0, which means there should be no panning at all. For each item, the actual translation value is randomly chosen between the min and max translation values set here.
    • Max possible translation: indicate the largest possible distance the pan effect should travel from the center of each item. The max possible value is 1, meaning the pan should extend all the way to the edge of the displayed item. For each item, the actual translation value is randomly chosen between the min and max translation values set here.
    • Min possible angle: indicate the lower-bound compass direction in which the pan effect (the translation) should move. The smallest possible value, -180°, represents a West direction while 0° represents East. Movement through negative values from -180° to 0° means movement from West through South to East. For each item, the actual direction is randomly chosen between the min and max angles set here.
    • Max possible angle: indicate the upper-bound compass direction in which the pan effect (the translation) should move. The largest possible value, 180°, represents a West direction (identical to -180°) while 0° represents East. Movement through positive values from 180° to 0° means movement from West through North to East. For each item, the actual direction is randomly chosen between the min and max angles set here.

    Animation effect guidance

    • To eliminate zoom entirely, set both Min possible zoom and Max possible zoom to 1.
    • To eliminate pan entirely, set Min possible translation and Max possible translation to 0.
    • To eliminate random pan directions, set Min possible angle and Max possible angle to the same value. For example setting both Min and Max angles to
      • 0° ensures the pan direction will always be due East
      • 90° ensures the pan direction will always be due North.
      • -90° ensures the pan direction will always be due South
      • 180° or -180° (they represent the same point) ensures the pan direction will always be due West
    • A zoom out starts at a randomly selected zoom factor and moves out towards a zoom factor of 1. A zoom in starts at a zoom factor of 1 and then moves in towards a randomly selected zoom factor.
