Detailed Description

Parameters giving detailed control of the perspective view.

Constructor & Destructor Documentation

TPerspectiveParam()

CartoType::TPerspectiveParam::TPerspectiveParam ( const char *  aText )

explicit

Reads a perspective parameter object from its XML form. Throws an exception if there is an error.

Member Function Documentation

operator!=()

bool CartoType::TPerspectiveParam::operator!= ( const TPerspectiveParam &  aP ) const

inline

The inequality operator.

operator<()

bool CartoType::TPerspectiveParam::operator< ( const TPerspectiveParam &  aP ) const

inline

The less-than operator.

operator==()

bool CartoType::TPerspectiveParam::operator== ( const TPerspectiveParam &  aP ) const

inline

The equality operator.

ReadFromXml()

TResult CartoType::TPerspectiveParam::ReadFromXml

(

const char *

aText

)

Reads a perspective parameter object from its XML form. Returns an error code; does not throw exceptions.

ToXml()

std::string CartoType::TPerspectiveParam::ToXml

(

)

const

Creates a string representing a perspective parameter object in XML.

Member Data Documentation

iAutoAzimuth

bool CartoType::TPerspectiveParam::iAutoAzimuth = true

If true, ignore iAzimuthDegrees and use the current map orientation.

iAutoPosition

bool CartoType::TPerspectiveParam::iAutoPosition = true

If true, ignore iPosition, and set the camera position so that the location in the center of the display is shown.

iAzimuthDegrees

double CartoType::TPerspectiveParam::iAzimuthDegrees = 0

The azimuth of the camera in degrees going clockwise, where 0 is N, 90 is E, etc.

iDeclinationDegrees

double CartoType::TPerspectiveParam::iDeclinationDegrees = 30

The declination of the camera downward from the horizontal plane. Values are clamped to the range -90...90.

iFieldOfViewDegrees

double CartoType::TPerspectiveParam::iFieldOfViewDegrees = 22.5

The camera's field of view in degrees.

iHeightInMeters

double CartoType::TPerspectiveParam::iHeightInMeters = 0

The height of the camera above the terrain. The value 0 causes a default value to be used, which is the width of the display.

iPositionDegrees

TPointFP CartoType::TPerspectiveParam::iPositionDegrees

The position of the point on the terrain below the camera, in degrees longitude (x) and latitude (y).

iRotationDegrees

double CartoType::TPerspectiveParam::iRotationDegrees = 0

The amount by which the camera is rotated about its axis, after applying the declination, in degrees going clockwise.
