Retouching and transforming
Last updated 1/10/2010
•
To transform multiple layers, do either of the following in the Layers panel: link the layers together, or select
multiple layers by Ctrl-clicking (Windows) or Command-clicking (Mac
OS) more than one layer. In the Layers
panel, 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 panel.
•
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 panel.

Set or move the reference point for a transformation
All transformations are performed around a fixed point called the reference point. By default, this point is at the center
of the item you are transforming. However, you can change the reference point or move the center point to a different
location using the reference point locator in the options bar.
1
Choose a transformation command. 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.
Scale, rotate, skew, distort, apply perspective, or warp
1
Select what you want to transform.
2
Choose Edit > Transform
> Scale, Rotate, Skew, Distort, Perspective, or Warp.
Note: If you are transforming a shape or entire path, the Transform menu becomes the Transform Path menu. If you are
transforming multiple path segments (but not the entire path), the Transform menu becomes the Transform Points menu.
3
(Optional) In the options bar, click a square on the reference point locator
.

Do one or more of the following:
•
If you chose Scale, drag a handle on the bounding box. Press Shift as you drag a corner handle to scale
proportionately. When positioned over a handle, the pointer becomes a
double arrow.
•
If you chose Rotate, move the pointer outside the bounding border (it becomes a curved, two-sided arrow), and
then drag. Press Shift to constrain the rotation to 15° increments.
•
If you chose Skew, drag a side handle to slant the bounding box.
•
If you chose Distort, drag a corner handle to stretch the bounding box.
•
If you chose Perspective, drag a corner handle to apply perspective to the bounding box.
