| 1. A method of digitizing graphic information comprising using a processor to perform the steps of:
displaying a basic layer in a screen;
converting raster data of alphabetic information into text data;
deleting the raster data corresponding to the alphabetic information after the text conversion;
performing batch conversion into short vectors for the raster data excluding the alphabetic information;
automatically connecting the short vectors that are in contact with coordinate axes X and Y;
storing the automatically-connected polylines in element layers; and
arranging the layers for every element and automatically connecting incomplete free curves or straight-lines between two points
away from each other to form the polylines.
