TextTable
public TextTable(CoverageTable cov,
TileDirectory tile)
throws FormatException
- Construct a TextTable for reading VPF text features.
- Parameters:
cov - the CoverageTable for the tiletile - the tile to parse
- Throws:
FormatException - if something goes wrong reading the text
getCoordinates
public CoordFloatString getCoordinates(java.util.List<java.lang.Object> textprim)
- Returns the coordinate string for the text primitive
