Dividing user slices and auto slices

The Divide Slice dialog box lets you divide slices horizontally, vertically, or both. In Photoshop, you can divide only one slice; in ImageReady, you can divide multiple slices at the same time. Duplicate slices are always user slices, regardless of whether the original is a user slice or an auto slice.

Note: You cannot divide layer-based slices.

To divide slices:

1. Select a slice. In ImageReady, you can select multiple slices.
2. Do one of the following:
• (Photoshop) With the slice select tool selected, click Divide Slice in the options bar.
• (ImageReady) Choose Slices > Divide Slice(s).
• (ImageReady) Choose Divide Slice(s) from the Slice palette menu.
3. Select Preview in the Divide Slice dialog box to preview the changes.
4. In the Divide Slice dialog box, select one or both of the following options:
• Divide Horizontally Into to divide the slice lengthwise.
• Divide Vertically Into to divide the slice widthwise.
5. Define how you want to divide each selected slice:
• Select and enter a value for slices down or slices across to divide each slice evenly into the specified number of slices.
• Select and enter a value for pixels per slice to divide each slice based on the specified number of pixels. Any section of a slice that is left over is made into another slice. For example, if you divide a slice that is 100 pixels wide into three new slices each 30 pixels wide, the remaining 10-pixel-wide area becomes a new slice.
6. Click OK.
