To control the colors in a tracing
Create a swatch library that contains the colors you want to use in the tracing. (See "To create swatch libraries" on
1
page 194.)
Make sure that the swatch library is open, and click the Tracing Options Dialog button
2
Alternatively, choose Object > Live Trace > Tracing Options.
3 Select the swatch library name from the Palette menu, and click Trace.
Tracing options
Specifies a tracing preset.
Preset
Specifies a color mode for the tracing result.
Mode
Specifies a value for generating a black and white tracing result from the original image. All pixels lighter
Threshold
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.)
Specifies a palette for generating a color or grayscale tracing from the original image. (This option is
Palette
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.
Specifies a maximum number of colors to use in a color or grayscale tracing result. (This option is
Max Colors
available only when Mode is set to Color or Grayscale and when Palette is set to Automatic.)
Creates a new swatch in the Swatches palette for each color in the tracing result.
Output To Swatches
Blurs the original image before generating the tracing result. Select this option to reduce small artifacts and
Blur
smooth jagged edges in the tracing result.
Resamples the original image to the specified resolution before generating the tracing result. This option
Resample
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.
Creates filled regions in the tracing result.
Fills
Creates stroked paths in the tracing result.
Strokes
Specifies the maximum width of features in the original image that can be stroked. Features
Max Stroke Weight
larger than the maximum width become outlined areas in the tracing result.
Specifies the minimum length of features in the original image that can be stroked. Features
Min Stroke Length
smaller than the minimum length are omitted from the tracing result.
Controls the distance between the traced shape and the original pixel shape. Lower values create a
Path Fitting
tighter path fitting; higher values create a looser path fitting.
Specifies the smallest feature in the original image that will be traced. For example, a value of 4
Minimum Area
specifies that features smaller than 2 pixels wide by 2 pixels high will be omitted from the tracing result.
Specifies the sharpness of a turn in the original image that is considered a corner anchor point in the
Corner Angle
tracing result. For more information on the difference between a corner anchor point and a smooth anchor point,
see "About paths" on page 144.
