Important: You cannot transform the background layer. To transform it, first convert it to a regular layer. • To transform part of a layer, select the layer in the Layers palette, and then select part of the image on that layer. • To transform multiple layers, do either of the following in the Layers palette: link the layers together, or select multiple layers by Ctrl-clicking (Windows) or Command-clicking (Mac OS) more than one layer. In the Layers palette, you can also Shift-click to select continguous layers. • To transform a layer mask or a vector mask, unlink the mask and select the mask thumbnail in the Layers palette. • To transform a path or vector shape, use the Path Selection tool to select the entire path or the Direct Selection tool to select part of the path. If you select one or more points on a path, only those path segments connected to the points are transformed. • To transform a selection border, make or load a selection. Then choose Select > Transform Selection. • To transform an alpha channel, select the channel in the Channels palette. See also "Link and unlink layers" on page 284 "Select a path" on page 372 Set or move the reference point for a transformation All transformations are performed around a fixed point called the reference point.

A bounding box appears in the image. 2 Do one of the following: • In the options bar, click a square on the reference point locator . Each square represents a point on the bounding box. For example, to move the reference point to the upper left corner of the bounding box, click the top left square on the reference point locator. • In the transform bounding box that appears in the image, drag the reference point . The reference point can be outside the item you want to transform.
