FILI
Specifies the name of the file that contains the input vector segment to be processed.
DBVS
Specifies the input segment containing the polygon vectors from which the line layer will be created. The input vector layer can either be whole polygons or topological polygons.
FILO
Specifies the output file name.
DBSD
Specifies a descriptor for the output line segment. Descriptor may be up to 64 characters long. When nothing is specified a default description is generated.
FTYPE
Optionally specifies the output file format type, represented by a three- or four-letter code. The format type must be a GDB-recognized file type. If FILO specifies an existing file, FTYPE should not be specified since the existing file will be updated and its type won't be changed.
For a complete list of GDB-recognized file types and their codes, see GDB file formats in the Technical Reference section of the CATALYST Professional online Help.
FOPTIONS
Optionally specifies the file creation options to be applied when creating the output file. These are specific to the file format; in each case, the default of no options is allowed. FOPTIONS can be used to specify the compression schemes, file format subtypes, and other information.
Different options are available for different file types (see the FTYPE parameter). The options are described in GDB file formats in the Technical Reference section of the CATALYST Professional online Help.
For PIX format, FOPTIONS defaults to BAND.

POLY2LINE creates a line layer from a polygon layer. All of the edges of the polygons are convereted to lines with all vertices being preserved.

A line segment is built based on the polygon segment 31 in irvine.pix and is also saved to irvine.pix.
