Creating user slices
You can create user slices with the Slice tool or from guides.
To create a slice with the Slice tool:
- Select the Slice tool
. Any existing slices automatically display in the document window. - 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.
- 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 View > Snap To align a new slice to a guide or another slice in the image. (See Moving and resizing user slices.)
To create slices from guides:
- Add guides to an image. (See Using guides and the grid.)
- 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):
- Select a portion of the image.
- 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.
