Programming

Animated Transitions

Animated transitions are used to add motion and effects to the transition from one page to another on a panel.
With existing panel firmware, page flip transitions occur with the new page immediately drawing over the
existing page on the screen. With animated transitions, the old page is moved, faded, or overdrawn from the
screen while the new page is drawn. These operations use the OpenGL hardware accelerator to ensure smooth
transitions.
Current panel firmware also supports animated buttons and popup page effects. This functionality is
unchanged.
In all cases, once the transition is triggered, the old page is frozen. For example, if the old page had an
animated button, the motion on that button would stop as soon as the transition is triggered. If there is motion
on the new page such as an animated button or even a popup effect, this motion will operate even while the
overall page itself is in motion as part of the transition.
Seven different classes of transitions are supported. Each transition class is described below. All of the
transition classes, with the exception of Page Curl, are commanded transitions. Once the transition is triggered,
it proceeds to completion. Page Curl can be interrupted and directed by the person touching the LCD as
described below.
Transition Classes
Slide
Slide with
bounce
Black glass
Fade
Page curl
Door with fade
Center door with
fade
The origin of the transition is the point on the LCD where the motion originates. In most cases, these locations
are the top, bottom, left and right of the screen. For example, a slide transition with a left origin will appear to
slide in from the left towards the right of the screen.
Slide, slide with bounce, door with fade and center door with fade can originate from the top, bottom, left and
right sides of the screen. Black glass can originate from the left or right. Fade does not need an origin since the
entire screen fades together. Page curl originates from the four corners of the screen: upper left, lower left,
upper right and lower right.
The transition time is the amount of time required for the transition to operate from start to finish. This value
can be specified from 0.3 seconds to 3.0 seconds in tenths of a second. If not specified, the default is 1.5
seconds.
Transition times are based on real world clock time and do not vary based on the speed of the processor or the
frame rate at which the display system is running.

The current page slides off of the screen and the new page slides in until it completely
covers the screen and stops. There is no gap between pages, so if the page
backgrounds match, this effect can give the appearance of moving around on a canvas
that is larger than the physical screen size.
This is the same as a slide transition, but with a bounce effect added when the new page
reaches the edge of the screen across from where it originated.
The existing page appears to move away from the viewer and off to the side. As soon as
it is completely off the screen, the new page moves in and toward the viewer from the
opposite edge of the screen. Both the old and new pages have a reflection on the bottom
that makes it appear that the page is sliding along black reflective glass.
The current page fades out while the new page fades in.
The existing page appears to be peeled away like a sheet of paper, revealing the new
page underneath. The new page has a shadow effect, and a faint reversed impression of
the old page can be seen through the back of the paper being flipped. This transition can
be interrupted by the user by holding a finger on the LCD and moving it around. The
corner of the paper will follow the user's finger until released, causing the transition to
proceed to completion. For the best effect, the button that triggers the page curl effect
should be placed near the corner of the screen from which the page curl will originate.
The new page moves over the existing page like a door with a hinge at the edge of the
LCD. In addition, the new page is semi-transparent, allowing the old page to be seen
through until the transition is finished, at which point the old page has faded away.
This transition operates as above, except that the hinge point is at the center of the LCD
rather than the edge.
