13 Vectorization The figure illustrates a symbol template where the connecting lines are worth adding An arbitrary number of connecting lines can be specified. If the connecting lines are set in the symbol template, then only those symbols will be retrieved which have raster straight lines similar to the symbol's, with the same points and at the same angles, as on the template; their lengths can differ from the length of the connecting line set in the template. To create new vector symbol template 1 Draw vector objects, approximating raster symbols, or create them using vectorization or tracing procedures. Because of SRTL editor window is modeless, these operations can be done even this dialog is open. ÞIt is recommended to unite objects of a vector template in a named block. After vectorization with symbol recognition or after the Search and Replace operations all named blocks can easily be replaced with other graphic symbols, for example, by applying the standard procedure of block redefinition. 2 Select created objects, using standard vector selection tools. 3 To add selected vector objects as Replace item click the Add Replace Item button. The selected objects will be included as new symbol template into SRTL. The new one Replace item with corresponded to it Search item will be included into the current library. To add selected vector objects as Search item select appropriate vector Replace item in the left dialog window, because the Search item could be added only to existing Replace item. It is not possible to add vector symbol template as a Search item for a raster Replace item. Click the Add Search Item button. The selected objects will be included as new symbol template into SRTL. The new one Search item corresponding to the specified Replace item will be appeared in the left dialog window. 4 Select the newly added Search item in the left dialog window. 217
