Detailed Description

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)".

Parameters

useOld3D true or false

void geos::io::WKTWriter::setOutputDimension ( uint8_t newOutputDimension )

void geos::io::WKTWriter::setRoundingPrecision ( int p0 )

Sets the rounding precision when writing the WKT a precision of -1 disables it

Parameters

p0	the new precision to use

void geos::io::WKTWriter::setTrim ( bool p0 )

Enables/disables trimming of unnecessary decimals

Parameters

p0	the trim boolean
