We have already learned how to create links and how to modify what part of a button will be highlighted.
When you Simulate the Menu you will see that all links are highlighted with the same color and with some transparency. The Map tab on the Menu Properties is for setting these parameters.
Note: The changes to Color Map can be seen directly in Simulation. That means you can stay in Simulation mode and change the parameters with immediate results.
Any active object can be in one of the three groups 1,2 or 3 (also called E1, E2 and P). By default all buttons are set to group 3.
Each of the Button Hi-lite groups can have different color properties.
Three color groups can be used together to create an antialiased subpicture. DVD-lab will use the three groups of color to create a color fade on the edges. The edges will then appear smoother, but this will allow you to use only one color and transparency value for highlighting the buttons on the menu.
Transparency and Color
On the example below the Frame with link is also set to group 3 so the third slider will affect it.
Notice the different settings for the highlighted image. The slider is the transparency of the highlighted picture (left - fully transparent, right - opaque).
To change the color, click on the color well on left of the slider.
You will be given a palette of 16 colors to choose from.
A Button State
An active object can have 3 Hi-lite states: Normal, Selected and Activated.
Normal state is when the button is not selected. A most common setting is that in a Normal state the Hi-lite picture is fully transparent.
Selected state is when the button is selected. This is where you do most of the changes, because this is a Hi-lite state what user will see the most.
Activated state is when the user clicks on the button (press Enter on their remote). This state will briefly appear before the button goes to the link.
To change the color settings for each state, click on the left or right arrows near the State indicator:
Here are the default settings for each state and Hi-lite group
Again note, that in the Normal State all groups are fully transparent. That means you don't see any Hi-lite picture if the button is not selected. However, in some cases such as for motion menus, you may use also the Normal state.
All this may seems to be a bit overwhelming but it is really quite easy to master.
A small challenge
Here is an example of what you can do with the features we just described. By combining all the accumulated knowledge of Frames, Visibility, Groups and Color Maps you should be able to produce the buttons below (displayed as not-selected, selected and activated).
The palette is a common color set for the whole project. You can change the Palette in the menu Project - Project Properties.
