You can choose options and
preset configurations in the
Auto Trace dialog box.
A To use a preset configura-
tion, select its name in the
pop-up menu. Preset configu-
rations and those you save ap-
pear in the menu.
Channel. Choose a channel of
the image to trace.
Curves or Polygons. Click an
option to set the trace meth-
od. Curves creates paths with
smooth anchor points as
needed. Polygon creates
paths without curved seg-
ments. Polygon can be better
for tracing straight lines, but
can make jagged shapes.
Curves makes segments with
fewer anchor points.
Fixed End. Aligns the trace
with the end points of the
image. Available when you
select the Curves option.
Corners. Creates corner
points that let you modify one
curve segment without affect-
ing the other. Use the Round-
Sharp slider to control the cor-
ner sensitivity. Available
when you select the
Curves option.
Smooth. Traces without
corner points when the
Corners option is off. If
Smooth and Corners are
on, angles within the speci-
fied sharpness are traced
as corner points. Available
when you select the
Curves option.
Centerline. Traces one
line through the middle of
large solid areas instead of
tracing along edges. Available
when you select the Curves
and Polygons options.
Filter. Prevents the tracing of
small, random elements, such
as tiny lines and dots. Avail-
able when you select the
Curves and Polygons options.
Invert Map. Inverts lightness
values (as in a negative image)
of the channel for tracing.
Available when you select the
Curves and Polygons options
Loose-Tight. Drag the slider
toward Tight for more exact
tracing with more anchor
points. Drag the slider toward
Loose for a looser tracing with
fewer anchor points.
Round-Sharp. Drag the slider
toward Round to get rounder
corners. Drag the slider toward
Sharp to get sharper corners.
