Member Function Documentation

addPolyElem()

void Polygons::addPolyElem

(

const PolyElem &

polyelem

)

Add the PolyElem to the list of polygons. This is performed only if the current PolyElem contains at least 3 vertices.

Parameters

polyelem

create()

Polygons * Polygons::create ( )

static

createFromCSV()

Polygons * Polygons::createFromCSV ( const String &  filename, const CSVformat &  csv = CSVformat(), int  verbose = false, int  ncol_max = -1, int  nrow_max = -1  )

static

createFromDb()

Polygons * Polygons::createFromDb ( const Db *  db, double  dilate = 0., bool  verbose = false  )

static

createFromNF()

Polygons * Polygons::createFromNF ( const String &  neutralFilename, bool  verbose = false  )

static

createFromWKT()

Polygons * Polygons::createFromWKT ( const String &  filename, const CSVformat &  csv = CSVformat(), int  verbose = false, int  ncol_max = -1, int  nrow_max = -1  )

inside()

bool Polygons::inside	(	const VectorDouble &	coor,
		bool	flag_nested = false
	)		const

Check if one point belongs to a Polygons

Returns

1 if the point belongs to the Polygons; 0 otherwise

Parameters

[in]	coor	Vector of coordinates
[in]	flag_nested	Option for nested polyelems (see details)

Remarks

When coor is dimensioned to 3, the third dimension test is performed

If flag_nested=TRUE, a sample is masked off if the number of

polyelems to which it belongs is odd

If flag_nested=FALSE, a sample is masked off as soon as it

belongs to one PolyElem

	)

Reset the Polygon from a CSV file

Parameters

filename	Filename

nrow_max	Maximum number of rows

Returns

resetFromDb()

int Polygons::resetFromDb	(	const Db *	db,
		double	dilate = 0.,
		bool	verbose = false
	)

resetFromWKT()

int Polygons::resetFromWKT	(	const String &	filename,
		const CSVformat &	csv,
		int	verbose = false,
		int	ncol_max = -1,
		int	nrow_max = -1
	)

Reset the Polygon from a CSV file using WKT format (first column) exported by QGIS

Parameters

filename	Filename
csv	CSV characteristics
verbose	Verbose flag
ncol_max	Maximum number of columns
nrow_max	Maximum number of rows

Returns

setX()

void Polygons::setX	(	int	ipol,
		const VectorDouble &	x
	)

setY()

void Polygons::setY	(	int	ipol,
		const VectorDouble &	y
	)

toString()
