Visually check the quality of the recognized objects, their color and degree of
conformity to the raster image. Re-customize parameters if necessary.
To see lines of different colors on separate layers, switch on the Separate by color
checkbox.
Set the color Number value (usually 1-2 colors more than the real number). The
program automatically defines the table of colors and casts the color of an object to
the nearest one. By switching on/off the Export to Layer checkbox located at the
beginning of every color table string, all objects of this color can be checked
visually.
After defining the correct number of colors it is possible to define another target
color and a layer for each real color.
If there is no need to export a line of a certain color, then switch off the Export
checkbox at the beginning of this string.

The Separate by color section tries to automatically
reduce the colors of all raster lines to a fixed number
(Real color column). Only the number of the colors to
reduce to need to be set (usually, 1-2 colors more than
the real number). Because the color of a raster line can
slightly vary from its beginning to its end after vectorizing
vector polylines of two different colors are produced
whereas the actual color is the same.
Turn it off to exclude polylines of a specified color from the
vectorization process.
A fixed number of colors that is generated automatically
by the color Conversion tool on the basis of the color
Number value.
Set a layer for the vector set of a specified color.
