(See "Storing masks in alpha channels" on page 280.) Setting the reference point 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. To set the reference point for a transformation: 1 Select a transformation command, as described in the following topics. A bounding box appears in the image. 2 In the options bar, click a square on the reference point locator . Each square represents a point on the bounding box. For example, to set the reference point to the top left corner of the bounding box, click the top left square on the reference point locator. To move the center point for the transformation: 1 Select a transformation command, as described in the following topics. A bounding box appears in the image. 2 Drag the center point.The center point can be outside the item you want to transform. Applying transformations The commands under the Transform submenu let you apply the following transformations to an item: • Scaling enlarges or reduces an item relative to its reference point.You can scale horizontally, vertically, or both horizontally and vertically. • Rotating turns an item around a reference point. By default, this point is at the center of the object; however, you can move it to another location. • Skewing lets you slant an item vertically and horizontally. • Distorting lets you stretch an item in all directions. • Applying perspective lets you apply one-point perspective to an item. In Photoshop, you can perform several commands in succession before applying the cumulative transformation. For example, you can choose Scale, drag a handle to scale, and then choose Distort, drag a handle to distort, and press Enter or Return to apply both transformations. In ImageReady, you can perform multiple types of transformations at the same time using the Transform > Numeric command. Using Help | Contents | Index Back 182
