To create a slice from a selection (ImageReady)
1
Select a portion of the image.
2
Choose Select > Create Slice From Selection.
ImageReady creates a user slice based on the selection marquee. If the selection is feathered, the slice covers the full
selection (including the feathered edges). If the selection is nonrectangular, the slice covers a rectangular area large
enough to enclose the full selection.
Layer-based slices
When you create a slice from a layer, the slice area encompasses all the pixel data in the layer. If you move the layer
or edit the layer’s content, the slice area automatically adjusts to encompass the new pixels.
A layer-based slice is updated when the source layer is modified.
Layer-based slices are especially useful when you work with rollovers. If you apply an effect to the layer—such as a
drop shadow or glow—to create a rollover state, the slice automatically adjusts to encompass the new pixels.
However, do not use a layer-based slice when you plan to move the layer over a large area of the image during an
animation, because the slice dimension may exceed a useful size.
Layer-based slices are less flexible and have fewer options; however, you can convert (“promote”) a layer-based slice
or an auto slice to a user slice at any time.
To create a slice from a layer
1
Select a layer in the Layers palette.
2
Choose Layer > New Layer Based Slice.
Converting auto slices to user slices
You can move, duplicate, combine, divide, resize, delete, arrange, align, and distribute user slices. You can also apply
different optimization settings to user slices. In contrast, all auto slices in an image are linked and share the same
optimization settings. This is because auto slices are regenerated every time you create or edit a user slice or layer
based slice.
If you select an auto slice and link it to a user slice, the user slice takes on the optimization settings of the auto slice.
If you select the user slice first, however, the auto slice is
promoted
to a user slice. Unlinking promotes auto slices to
user slices. See “To link slices (ImageReady)” on page 584.
