Open button to open existing library and the

Þ Since libraries are stored in separate files, these can be deleted and copied,
using standard operating system tools.
To insert a symbol template saved in an obsolete format, click the
button and choose the *.SST file. The new one Replace item with corresponded to it
Search item will be included into the current library.
Vector symbol template
Vector symbol templates are marked with
templates are used for recognizing raster symbols in such commands as symbol
automatic vectorization, symbol tracing, symbol selecting and Search and Replace.
In Search and Replace vector template can be used not only for finding raster
symbols, but for vector too.
Before defining such a template for raster symbols recognition, create vector
objects resembling the raster symbols. This can be done through vectorization,
tracing or simply by drawing vector objects.
The set of such vector objects is used as a vector template. The template can
consist of any set of objects, but for recognition only objects like line, arc, circle and
polyline are used. The objects of a template can also be united in the block.
New vector template could be added to SRTL as Replace item or as Search item.
When "Add Replace item" was performed, SRTL create new Replace item and
associated new Search item with the same topological structure. The Search item
could be added only to existing and selected Replace item.
Search item can have connecting lines. The setting of connecting lines increases
the accuracy of symbols recognition, due to more exact and flexible description of
the symbol geometry.
The connecting line is a vector object included in the template. One end of the
connecting line joins the other objects in the template; the other end is free. The
length of symbol parts corresponding to connection lines can be arbitrary.
