In Example 2 I played with the Color Threshold
parameter, testing 50 and 20. As you can see the detail kicks
up many times. The problem is file size. Using a setting
of '50' results in a 30kb file. Using '25' results in a 57kb
file. The original .jpg file was only 18kb.

Example 2: Threshold 50

Example 3: Threshold 25

Finding the optimum result in this process
is less a science than an art. If your desire is to create
a vector graphic that looks very much like a bitmap you might
want to use the original bitmap. The file sizes are often
smaller and better detailed. However if you wish to create
a graphic that can be edited, animated or if you want to
create a unique graphic the 'Trace Bitmap' command can be
very useful.
