Function Documentation

◆ parse_wkt()

bool gis::srs::parse_wkt	(	gis::srid_t	srid,
		const char *	begin,
		const char *	end,
		Spatial_reference_system **	result
	)

Parse an SRS definition WKT string.

The parser understands WKT as defined by the <horz cs> specification in OGC 01-009.

If the string is successfully parsed, a new SRS object will be allocated on the heap. The caller is responsible for deleting it.

If an error occurs, no object is allocated.

Parameters

[in]	srid	Spatial reference system ID to use when reporting errors
[in]	begin	Start of WKT string in UTF-8
[in]	end	End of WKT string (one past the last byte)
[out]	result	Spatial reference system

Return values

true	An error has occurred
false	Success
