MapInfoPosition (Function)

In french: CarteInfoPosition

Returns the coordinates (in pixels) of the point corresponding to a geographical position (latitude and longitude).

Note: This function is available in the Android emulator and in the Android simulator.

Example

// Retourne le point de la carte correspondant à la position courante de l'utilisateur
MaPosition is geoPosition
MaPosition.Latitude = 1.442951
MaPosition.Longitude = 43.604363
Trace(MapInfoPosition(CARTE_Position, MaPosition))

// Retourne le point de la carte correspondant à la position courante de l'utilisateur
MaPosition is geoPosition
MaPosition = GPSGetPosition()
IF ErrorOccurred = False THEN
	RETURN MapInfoPosition(CARTE_Position, MaPosition)
END

Syntax

<Result> = MapInfoPosition(<Map control> , <Position>)

<Result>: Character string

Coordinates of the point corresponding to the geographical position. The coordinates are returned in the following format:
<X> + TAB + <Y>

<Map control>: Control name

Name of the Map control to be used. If this parameter corresponds to an empty string (""), the Map control to which the current event belongs will be used.

<Position>: geoPosition variable

Name of a variable of type geoPosition corresponding to the geographic position whose coordinates are sought on the map.

Remarks

The coordinates returned by MapInfoPosition can correspond to a point that is not currently visible in the Map control (negative coordinates for example).
The calculation of position takes into account the zoom level in the Map control during the call to the function. The higher the zoom level is, the more precise the coordinates will be.
