Syntax | | This syntax is obsolete from version 2 of the mapping service: the Google key is not required anymore. |
Retrieving a map with configuration of centering Hide the details
<Result> = GglGetStaticMap(<Google key> , <Latitude> , <Longitude> , <Zoom> , <Image width> , <Image height> [, <Type of map> [, <Advanced parameters>]])
<Result>: Image variable Name of the Image variable containing the map. The map is returned to the specified dimensions. <Google key>: Character string (with quotes) Authentication key for the Google Maps service. This key is supplied by Google.Note: Since version 2 of the Google service, this parameter has become obsolete and it is ignored.Note: The Google key is required for an advanced use only (use with charge for more than 25000 requests per day). <Latitude>: Real Latitude of the central point of the map. <Longitude>: Real Longitude of the central point of the map. <Zoom>: Integer Zoom level. This parameter can correspond to:- an integer included between 0 (most distant zoom) and 19 (very close zoom, scale of a building for example).
- the gglAutoZoom constant. In this case, the zoom is automatically chosen according to the markers or to the area defined in <Advanced Parameters>. A WLanguage error occurs if this constant is used without <Advanced Parameters>.
<Image width>: Integer Width (in pixels) of the image of the map to retrieve. The maximum width is set to 640 pixels. This limit is defined by the Google Maps service at the date of publication of this page. <Image height>: Integer Height (in pixels) of the image of the map to retrieve. The maximum height is set to 640 pixels. This limit is defined by the Google Maps service at the date of publication of this page. <Type of map>: Optional character string constant Type of map to retrieve. This parameter can correspond to one of the following constants:
| | | gglHybrid | Combine the road map and the satellite view. | | gglMobileDevice | Map optimized for the constraints specific to the display on a Mobile device | gglRoadmap
(Default value) | Road map. | | gglSatellite | Satellite view. | | gglTerrain | Geographical map displaying the relief and the vegetation. |
<Advanced parameters>: Optional gglMapParameter variable Name of the gglMapParameter variable containing the advanced setting of the map. If this parameter is not specified, the map will be in Gif format and it will contain no marker, no path and no area. | | This syntax is obsolete from version 2 of the mapping service: the Google key is not required anymore. |

To get the key required for using the Google Maps service, go to the following address: Caution: the address of this page may have been modified since the publication date of this page. Possible error cases The Google Maps service may not be able to return a valid image according to the location or to the requested zoom. No data is returned if the limitations defined by the Google Maps service are exceeded (size of the image too large, too many points in a path, and so on). A "HttpBadRequest" error is returned. See the documentation about the gglMapParameter variables for more details.
