* clipvgf *
* *
* This program clips elements in a VGF file based on a bounds *
* specification. By default, a simple clipping algorithm is used *
* where element points either inside or outside the polygon are kept *
* or thrown away based on an input flag. Alternatively, an exact *
* algorithm may be requested which clips precisely at the borders. *
* *
* The bound definition must be in the format: *
* bound_name|<area_tag_name>area_tag_value *
* and must be enclosed w/ quotes so the shell will ignore directives. *
* *
* Examples: *
* clipvgf input.vgf "STATE_BNDS|<STATE>WY" keep output.vgf rough *
* clipvgf input.vgf "STATE_BNDS|<STATE>WY" keep output.vgf exact *
* Where "rough" uses the simple clipping algorithm and "exact" yields *
* precise clipping at the bounds borders. *
* *
* The following element classes are not processed: *
* CLASS_WATCHES, CLASS_TRACKS, CLASS_SIGMETS *
* *
* main(argc, argv) *
* *
* Input parameters: *
* argc int number of parameters of command line *
* argv char** parameter array of command line *
* *
* Output parameters: *
* Return parameters: *
* NONE *
* *
** *
* Log: *
* D.W.Plummer/NCEP 2/02 *
* D.W.Plummer/NCEP 5/02 Added exact clipping and label moving *
* D.W.Plummer/NCEP 8/02 Account for text grouped with symbol *
* D.W.Plummer/NCEP 8/02 Create output VGF, even if it is empty *
* H. Zeng/XTRIA 02/03 converted CLASS_CIRCLE to CLASS LINES *
* D.W.Plummer/NCEP 8/03 Bug fix - add pt to closed lines *
