vfvpick − Selects features from a VisionX vector format file

vfvpick [if=infile] [f=list] [ff=infile] [of=ofile] [-v]

vfvpick selects features from a VisionX vector format file based on a text file or command line argument specifying the desired features. The text file (if=) should contain the name of the desired features, one per line. Lines starting with # are ignored. Only the first word in the line is used. If a command line argument (f=) is specified, the names of the features must be separated by commas. The names of the features are matched with the elements in the text header of the vector format file; only those matching features are output. Description information is provided in the output if present in the input file.
