Note: If you often mask objects, you can add the Mask button to the toolbar by
choosing View > Customize Toolbar. The Mask button switches to Unmask when you
select a masked image.
To unmask an image (so that the whole image reappears):
m Select the image and choose Format > Unmask.
To crop an image using a predrawn or custom shape as a mask:
1 Insert the image you want to mask.
2 Add a shape to the slide to use for the mask.
3 Select both the image and the shape.
4 Choose Format > Mask With Shape.
5 Drag the shape to center it over the part of the image you want to feature. Drag its
selection handles to resize it.
6 Edit the mask as desired.
You can resize, rotate, and move the mask, and you can edit the contour of the mask
after double-clicking the edge of the shape. For details, see “Editing Predrawn and
Custom Shapes” on page 56.
7 Double-click the window to make the masked area invisible.
To change the portion of a masked image that’s visible:
1 Double-click the masked image.
2 Click the dotted border of the resizable window to select it.
3 Drag the selection handles to resize or Command-drag to rotate the visible portion of
the image, or drag the window to feature a different part of the image.
Grouping and Locking Objects
You can group objects together so that they can be moved, copied, resized, and
oriented as a single object. You can edit text associated with a shape or text object in
a group, but you can’t modify other attributes of individual objects in the group.
Lock objects to the canvas to avoid inadvertently moving them as you work.
To group objects:
1 Hold down the Command (or Shift) key as you select the objects you want to group
on the slide canvas.
