5. Choose Window > Show Vector Trace Palette. The options in this palette affect the

spline creation. Adjust the parameters if you are unable to create the spline that you

want. Since this is a floating window, you can leave it open while you work.

•The Trace Channel menu sets which channel the bitmap trace uses. Choose

Luminance, Alpha, Red, Green, or Blue.

• Trace Tolerance determines how closely the generated spline matches the actual

contour of the bitmap graphic. A smaller tolerance creates a spline with more points.

You may want to use a smaller tolerance if your graphic has complicated edges.

Alternatively, use a larger tolerance if your graphics edges are uneven. In this case a

larger tolerance can be used to give your graphic smoother edges.

• Trace Threshold sets the range of values that are used to create a particular spline

point.

•When the Invert checkbox is selected, the spline is created from the inverse of the

selection.

•When the Use Pre-Blur checkbox is selected, a blur is applied when finding the

spline edges.

• Pre-Blur Amount increases the amount of blur applied when creating the spline.

6. Use one of the following methods to create a spline of your imported still image.
