MACROMEDIA FREEHAND 10-USING FREEHAND Use Manual page 162

You can import bitmap artwork into FreeHand and then use the Trace tool to
create paths that follow the outlines of all or part of the artwork. You can trace all
of an image within the selection marquee, or you can trace just an area of
contiguous color within the image. The Trace tool traces any objects, including
FreeHand graphics, bitmap images, and text.
When scanning images to be traced in FreeHand, it is recommended that you use a
scan resolution between 300 and 600 dots per inch (dpi). Scanning at a resolution
higher than 600 dpi results in too many points. In addition, high-resolution
bitmap images require more RAM than lower-resolution images. If RAM is
limited, FreeHand uses the lowest allowable resolution setting when tracing.
When tracing bitmap and vector graphics, the default settings for the Trace tool
provide good results without using excessive system memory. Before tracing, you
should confirm the Trace Tool dialog box settings. The Trace tool's settings are
saved to the FreeHand Preferences file when you quit FreeHand.
FreeHand lets you choose several ways to convert color when tracing an object.
You can make the following conversions when tracing:
•
You can trace a color image to an RGB or CMYK color object.
•
You can trace a grayscale image to a grayscale object.
•
You can trace a color image as a grayscale object.
