43   \brief The SoVectorOutput class is used for setting vector output file.
44 
45   \ingroup hardcopy
46 
47   SoVectorizeAction will create an SoVectorOutput which will output
48   to stdout by default. SoVectorizeAction::getOutput() can be used to
49   fetch this output, and the user will probably want to set a
50   file to output to.
51 
52   \since Coin 2.1
53   \since TGS provides HardCopy support as a separate extension for TGS Inventor.
