Go to the Transparency panel and click the
opacity mask thumbnail, the one that looks like
a black head against a white background.
•
Choose Edit→Paste in Place or press the keyboard
shortcut Ctrl+Shift+V (-Shift-V). Illustrator adds
the blue path to the opacity mask.
The blue path diffuses Sam’s stumpy legs but does not
entirely erase them. When rendered within an opac-
ity mask, a colored path can hide elements of your
illustration on an ink-by-ink basis, but that’s not what
we’re looking for. We want to clip the pants entirely
under the piano. Which requires black.
18. Fill the blue path with black. On the far left side of
the control panel, select black for the fi ll color and
none
(
)
for the stroke. Illustrator now clips the pants
and the bottom of the suit to the left edge of the blue
keyboard, as shown in Figure 8-20.
19.
Rename the new masking path. Note that Illustrator
has renamed the Layers panel Layers (Opacity Mask)
and it contains just one item, <Opacity Mask>. Twirl
this item open to reveal two paths, one for the piano
and the other for Sam’s head. Double-click the item
called <Path> and rename it “piano.”
20.
Exit the opacity mask. Try clicking part of the jacket
and note that Illustrator refuses to select it. This is
because editing an opacity mask amounts to a kind
of isolation mode. You can select the head and the
piano—the two paths in the
