in the previous state. You can then use the Layers
palette to make changes to the image in the new
state. You can also add an animation to a
rollover state.
The Rollover palette with three rollover states. The dark
border around the middle thumbnail indicates that
the Over state is selected.
When you save an image with rollover states as a
Web page, each rollover state is saved as a separate
image file. By default, rollover states are named
using the corresponding slice name plus the
mouse action that triggers the rollover state. When
you change the name of a slice, rollover states in
the slice are renamed.
Working with layers in rollovers
How you work with layers is an essential part of
creating rollovers. Placing the image content for a
rollover on its own layer allows you to use Layers
palette commands and options to create rollover
effects. When creating rollovers or animations,
some changes you make to a layer affect only the
active state or frame, while others affect all states
or frames. (See "Using layers to edit frames" on
page 306.)
When creating a slice for a rollover, use a layer-
based slice. This is recommended because the
dimensions of a layer's content may change in the
course of creating a rollover, and layer-based slices
automatically adjust to encompass the new pixels.
However, do not use a layer-based slice when you
plan to move the layer over a large area during an
animation, because the slice dimension may
exceed a useful size. (See "Creating layer-based
slices" on page 273.)
You can use layer styles to create instant rollover
effects. When working with layer-based slices,
you can also save the series of states as a rollover style.
(See "Applying and creating rollover styles" on
page 296.)
Using the Rollover palette
You use the Rollover palette to create and set
options for rollover states. The Rollover palette
displays thumbnails for each state of a rollover.
The first state in the Rollover palette is always the
Normal state.
To change the thumbnail view of rollover states:
Choose Palette Options from the Rollover
1
palette menu.
Select a thumbnail size.
2
3 Under Thumbnails Show, define the content of
the thumbnail:
• Current Slice to show only the current slice in
the thumbnail.
• Entire Document to show the entire image in the
thumbnail. This view is useful when creating a
secondary rollover effect.
