Detailed Description

The standard path class.

Constructor & Destructor Documentation

Outline() [1/2]

CartoTypeCore::Outline::Outline

(

const MPath &

aPath

)

Creates an Outline from a path object.

Outline() [2/2]

CartoTypeCore::Outline::Outline

(

const Rect &

aRect

)

Creates an Outline from a rectangle.

Member Function Documentation

AppendContour() [1/3]

Contour & CartoTypeCore::Outline::AppendContour ( )

inline

Appends a new empty contour to the outline and returns it.

AppendContour() [2/3]

void CartoTypeCore::Outline::AppendContour ( const MContour &  aContour )

inline

Appends a contour to the outline.

AppendContour() [3/3]

void CartoTypeCore::Outline::AppendContour ( Contour &&  aContour )

inline

Appends a contour.

begin() [1/2]

std::vector< Contour >::iterator CartoTypeCore::Outline::begin ( )

inline

Returns an iterator to the start of the vector of contours.

begin() [2/2]

std::vector< Contour >::const_iterator CartoTypeCore::Outline::begin ( ) const

inline

Returns a constant iterator to the start of the vector of contours.

Clear()

void CartoTypeCore::Outline::Clear ( )

inline

Clears the outline by removing all contours.

ContourByIndex() [1/2]

Contour & CartoTypeCore::Outline::ContourByIndex ( size_t  aIndex )

inline

Return a non-constant reference to a contour, selected by its index.

ContourByIndex() [2/2]

ContourView CartoTypeCore::Outline::ContourByIndex ( size_t  aIndex ) const

inlineoverridevirtual

Returns the contour indexed by aIndex.

Implements CartoTypeCore::MPath.

Contours()

size_t CartoTypeCore::Outline::Contours ( ) const

inlineoverridevirtual

Returns the number of contours.

Implements CartoTypeCore::MPath.

end() [1/2]

std::vector< Contour >::iterator CartoTypeCore::Outline::end ( )

inline

Returns an iterator to the end of the vector of contours.

end() [2/2]

std::vector< Contour >::const_iterator CartoTypeCore::Outline::end ( ) const

inline

Returns a constant iterator to the end of the vector of contours.

LatLongToMapCoordinates()

void CartoTypeCore::Outline::LatLongToMapCoordinates	(	const Projection &	aProjection,
		int32_t	aLatLongFractionalBits = 16
	)

Project an outline from degrees lat/long to map coordinates using the supplied projection. The input point format is degrees in fixed point form with a number of fractional bits determined by aLatLongFractionalBits (default = 16).

MapCoordinatesToLatLong()

void CartoTypeCore::Outline::MapCoordinatesToLatLong	(	const Projection &	aProjection,
		int32_t	aLatLongFractionalBits = 16
	)

Project an outline to degrees lat/long using the inverse of the supplied projection. The output point format is degrees in fixed point form with a number of fractional bits determined by aLatLongFractionalBits (default = 16).

MayHaveCurves()

bool CartoTypeCore::Outline::MayHaveCurves ( ) const

inlineoverridevirtual

Returns true if the path may have off-curve points.

Implements CartoTypeCore::MPath.

operator=() [1/2]

Outline & CartoTypeCore::Outline::operator=

(

const MPath &

aPath

)

Sets this outline to a path object.

operator=() [2/2]

Outline & CartoTypeCore::Outline::operator=

(

const Rect &

aRect

)

Sets this outline to a rectangle.

Read()

Outline CartoTypeCore::Outline::Read ( InputStream &  aInput )

static

Reads a serialized outline from a stream.

ReadFromXml()

Outline CartoTypeCore::Outline::ReadFromXml ( InputStream &  aInput )

static

Reads an outline from XML.

See also

MPath::WriteAsXml for the format.

RemoveData()

void CartoTypeCore::Outline::RemoveData ( std::vector< Contour > &  aDest )

inline

Removes the vector of contours and puts it into aDest.
