• 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.
Adjusting Control Points
You can modify a shape or mask directly in the Canvas. Once a shape or mask is drawn,
the Adjust Control Points tool is automatically selected.
To modify a shape’s control points in the Canvas:
1 Once the shape or mask is created, click the Select/Transform tool, and 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 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 819.
Object Geometry Controls in the Inspector
Layers 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.
When you select a single object and open the Properties tab of the Inspector, the
object’s parameters are displayed. Making changes to the values in the Properties tab
affects the selected object. If more than one object is selected in the Canvas, Timeline,
or Layers tab, the parameter values displayed in the Properties tab of the Inspector are
blank. Adjusting any parameter control affects every selected object equally.
To modify parameter values, do one of the following:
m Select a parameter value field, type a new number, then press Return.
m Drag a parameter’s slider.
