To control the colors in a tracing
1 Create a swatch library that contains the colors you want to use in the tracing. (See “To create swatch libraries” on
page 194.)
2 Make sure that the swatch library is open, and click the Tracing Options Dialog button in the Control palette.
Alternatively, choose Object > Live Trace > Tracing Options.
3 Select the swatch library name from the Palette menu, and click Trace.
Tracing options
Preset Specifies a tracing preset.
Mode Specifies a color mode for the tracing result.
Threshold Specifies a value for generating a black and white tracing result from the original image. All pixels lighter
than the Threshold value are converted to white, all pixels darker than the Threshold value are converted to black.
(This option is available only when Mode is set to Black and White.)
Palette Specifies a palette for generating a color or grayscale tracing from the original image. (This option is
available only when Mode is set to Color or Grayscale.)
To let Illustrator determine the colors in the tracing, select Automatic. To use a custom palette for the tracing, select
a swatch library name. (The swatch library must be open in order for it to appear in the Palette menu.) For additional
instructions, see “To control the colors in a tracing” on page 167.
Max Colors Specifies a maximum number of colors to use in a color or grayscale tracing result. (This option is
available only when Mode is set to Color or Grayscale and when Palette is set to Automatic.)
Output To Swatches Creates a new swatch in the Swatches palette for each color in the tracing result.
Blur Blurs the original image before generating the tracing result. Select this option to reduce small artifacts and
smooth jagged edges in the tracing result.
Resample Resamples the original image to the specified resolution before generating the tracing result. This option
is useful for speeding up the tracing process for large images but can yield degraded results.
Note: The resample resolution is not saved when you create a preset.
Fills Creates filled regions in the tracing result.
Strokes Creates stroked paths in the tracing result.
Max Stroke Weight Specifies the maximum width of features in the original image that can be stroked. Features
larger than the maximum width become outlined areas in the tracing result.
Min Stroke Length Specifies the minimum length of features in the original image that can be stroked. Features
smaller than the minimum length are omitted from the tracing result.
Path Fitting Controls the distance between the traced shape and the original pixel shape. Lower values create a
tighter path fitting; higher values create a looser path fitting.
Minimum Area Specifies the smallest feature in the original image that will be traced. For example, a value of 4
specifies that features smaller than 2 pixels wide by 2 pixels high will be omitted from the tracing result.
Corner Angle Specifies the sharpness of a turn in the original image that is considered a corner anchor point in the
tracing result. For more information on the difference between a corner anchor point and a smooth anchor point,
see “About paths” on page 144.
