13 Vectorization 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. related buttons and controls: Colour Number slider 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. Check box column Turn it off to exclude polylines of a specified color from the vectorization process. Real color column A fixed number of colors that is generated automatically by the color Conversion tool on the basis of the color Number value. Layer column Set a layer for the vector set of a specified color. 223
