To create a slice with the slice tool:
1
Select the slice tool
. Any existing slices automatically display in the document
window.
2
Choose a style setting in the options bar:
•
Normal to determine slice proportions by dragging.
•
Fixed Aspect Ratio to set a height-to-width ratio. Enter whole numbers or decimals for
the aspect ratio. For example, to create a slice twice as wide as it is high, enter 2 for the
width and 1 for the height.
•
Fixed Size to specify the slice’s height and width. Enter pixel values in whole numbers.
3
Drag over the area where you want to create a slice. Shift-drag to constrain the slice to a
square. Alt-drag (Windows) or Option-drag (Mac OS) to draw from the center. Use snap to
align a new slice to a guide or another slice in the image. (See
“Moving and resizing user
slices” on page 374
.)
To create slices from guides:
1
Add guides to an image. (See
“Using guides and the grid” on page 45
.)
2
Do one of the following:
•
(Photoshop) Select the slice tool, and click Slices From Guides in the options bar.
•
(ImageReady) Choose Slices > Create Slices from Guides.
When you create slices from guides, any existing slices are deleted.
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.
Creating 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.
