WiseImage - User's Guide chapter.. Polylines - approximates central lines of the raster text strings with polylines. Outlines - approximates boundaries of the raster text strings by outline polylines. OCR - recognizes raster text strings and creates AutoCAD text objects. The text style used for creation of these text objects is selected from the WiseImage tab of the Options dialog box of the AutoCAD system. The algorithm uses the values of the Height Table list of the Options tab as maximum height of raster text characters of the upper case. See more information on this and other parameters that influence text recognition on page 202. Symbols Selects the algorithm for raster symbol recognition with specified samples. The algorithm only works if the algorithms Lines and Arcs and Circles are on. Setting up the algorithm is made in the Symbols tab of the same dialog box as described on page 206. Options Tab WiseImage Pro uses the information on the sizes of vector objects raster analogues, which is set in the Options tab, to define an AutoCAD object with which a given raster object should be vectorized. 200
