The Marquee Tool
The Marquee tool helps you select part of an object in the shape of a rect-
angle, circle, or other shape. This tool is useful for cropping objects or pictures
to a standard shape.

2. On the Stack, click the object of which you want to make a partial selec
-
tion.
3. On the toolbar, click the Marquee Tool button .
4. If the Marquee Tool options palette is not visible in the workspace, click
the Selection button on the toolbar.
5. To keep the edges of the selection smooth, select the Anti-aliased check
box on the Marquee Tool options palette.
6. On the Marquee Tool options palette, click a shape for the marquee
selection.
7. To keep the marquee shape in a specific proportion, click Shape propor
-
tions on the Marquee Tool options palette, and then enter a height and
width.
8. On the Marquee Tool options palette, choose whether you want to make
a new selection

current selection
.
9. Drag the marquee pointer diagonally across the area you want to select.

picture), click Feather on the Marquee Tool options palette, enter the
number of pixels that you want feathered around the edge, and then click

Anti-aliasing a
selection
Anti-aliasing means
that pixels on the edge
of the selection can
be partially selected.
This technique helps to
smooth the transition
between the selection
and the surrounding
area. Anti-aliasing is
useful when creating
composites.
Feathering a
selection
Like anti-aliasing,
feathering a selection
helps to smooth its
edges. But where anti-
aliasing only affects
pixels directly on the
selection border, you
can feather a border
of up to 250 pixels
around the edge of the
selected area.
