2 In the Canvas, drag one of the eight handles around the edge of the object to crop it:
 Drag the top, left, right, or bottom handle to only crop that side.
 Drag one of the four corner handles to crop both corresponding sides
simultaneously.
 Press Shift while you drag to constrain corner edge cropping to the aspect ratio of
the object.
Note: If an object is corner-pinned, you can no longer enable the Crop mode in the
Canvas (onscreen controls). You can still crop a corner-pinned object by adjusting its
Crop parameter settings in the Properties tab of the Inspector.
Additionally, the crop area and the image can be manipulated separately.
To move the crop area while keeping the underlying image in place:
m Press Command and Option while you drag inside the crop area.
To move the image while keeping the crop area in place:
m Press Command while you drag inside the crop area.
Adjusting Control Points
You can modify a shape or mask directly in the Canvas.
To modify a shape’s control points in the Canvas:
1 Once the shape or mask is created, click and hold the Select/Transform tool, then
choose the Adjust Control Points tool from the pop-up menu.
Note: You can also double-click the shape, or Control-click the object, then choose Edit
Points from the shortcut menu to enter the Adjust Control Points mode.
The object’s control points become active.
2 In the Canvas, drag the points to modify the shape of the object.
For more information on working with shapes and masks, see “ Using Shapes and
Masks ” on page 997.
Object Geometry Controls in the Inspector
Groups and objects have the same geometric parameters in the Properties tab of the
Inspector. Manipulating a Canvas transform control also changes the corresponding
parameter in the Properties tab of the Inspector. If you want to transform an object
more precisely than the onscreen controls allow, you can change that parameter’s
value directly.
