Programming

Overview

You can program the MVP-9000i, using the commands in this section, to perform a wide variety of operations using Send
Commands and variable text commands.
A device must f irst be def ined in the NetLinx programming language with values for the Device: Port: System (in all
programming examples - Panel is used in place of these values and represents all Modero panels).
NOTE: Verify you are using the latest NetLinx Master and Modero f irmware, as well as the latest version of NetLinx Studio and TPD4.

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 This transition operates as above, except that the hinge point is at the center of the LCD rather than the edge.
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.
Since the transitions require OpenGL hardware acceleration, they are not seen by the user on a VNC connection. When a transition
is triggered, the user will see a normal page flip to the new page on the VNC connection, while the animated transition occurs as
expected on the panel.
MVP-9000i - Instruction Manual
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.
