Outputs the textual representation of a Geometry. See also WKTReader.
The WKTWriter outputs coordinates rounded to the precision model. No more than the maximum number of necessary decimal places will be output.
The Well-known Text format is defined in the OpenGIS Simple Features Specification for SQL.
A non-standard "LINEARRING" tag is used for LinearRings. The WKT spec does not define a special tag for LinearRings. The standard tag to use is "LINESTRING".
See WKTReader for parsing.
| void geos::io::WKTWriter::setOld3D | ( | bool | useOld3D ) | [inline] |
Enable old style 3D/4D WKT generation.
By default the WKBWriter produces new style 3D/4D WKT (ie. "POINT Z (10 20 30)") but if this method is used to turn on old style WKT production then the WKT will be formatted in the style "POINT (10 20 30)".
| useOld3D | true or false |
| void geos::io::WKTWriter::setRoundingPrecision | ( | int | p0 ) |
Sets the rounding precision when writing the WKT a precision of -1 disables it
| p0 | the new precision to use |
| void geos::io::WKTWriter::setTrim | ( | bool | p0 ) |
Enables/disables trimming of unnecessary decimals
| p0 | the trim boolean |
| static std::string geos::io::WKTWriter::toLineString | ( | const geom::CoordinateSequence & | seq ) | [static] |
Generates the WKT for a N-point LineString.
| seq | the sequence to outpout |
| static std::string geos::io::WKTWriter::toLineString | ( | const geom::Coordinate & | p0, |
| const geom::Coordinate & | p1 | ||
| ) | [static] |
Generates the WKT for a 2-point LineString.
| p0 | the first coordinate |
| p1 | the second coordinate |
| static std::string geos::io::WKTWriter::toPoint | ( | const geom::Coordinate & | p0 ) | [static] |
Generates the WKT for a Point.
| p0 | the point coordinate |
