- Properties specific to gglMapParameter variables
- Functions that use gglMapParameter variables
gglMapParameter (Variable type) In french: gglParamètreCarte
The type gglMapParameter type is used to define all the advanced features of a map: points, paths, etc. The characteristics of this map can be defined and modified using various WLanguage properties. Note: For more details on the declaration of this type of variable and the use of WLanguage properties, see Declaring a variable.
Params is gglMapParameter
M1 is gglMarker
M1.Latitude = 47.022356
M1.Longitude = 52.423654
M1.Color = 0x0000FF
M1.Size = gglSmall
Add(Params.Marker, M1)
Params.Format = gglJPG
Params.Border = True
Properties Properties specific to gglMapParameter variables The following properties can be used to define the characteristics of gglMapParameter variables: | | | | Property name | Type used | Effect |
|---|
| Area | gglCoordinate | Specifies the range in latitude and in longitude that must be displayed on the map. In order for this parameter to be taken into account, the <Zoom> parameter found in GglGetStaticMap must correspond to the gglAutoZoom constant. In previous versions, this property corresponds to Span. | | Border | Boolean | - True to add a border around the image,
- False to display no border.
The characteristics of the frame are as follows: blue frame, 5 pixels wide, with 55% opacity.Remark: since the switch to version 2 of Google's service, this parameter has become obsolete and is ignored. | | Format | String constant | Format of image received. This parameter can correspond to the following constants:- gglGIF (default): image in GIF format
- gglJPG: image in JPG format.
- gglJPGNonProgressive: image in non-progressive JPG format.
- gglPNG8: image in PNG 8 format
- gglPNG32: image in PNG 32 format
| | Language | Character string | Language in which the information will be displayed on the map. This parameter can correspond to "fr", "en", "de", ... | | Marker | Array of gglMarker | Markers to display on the map. The maximum number of markers that can be used is set to 50. This number is reduced if points are added (indeed, the size of the URL expected by Google limits the maximum number of markers). | | MobileDevice | Boolean | - True to retrieve a map optimized for the display on a mobile device,
- False otherwise.
| | Path | gglPath | Path to draw on the map. The drawing of the route uses the specified points (and not the streets on the map). The points are linked by a line. | | Scale | Integer | Modifies the number of pixels returned. This property is required for a display on a high-resolution screen. If the Scale property is set to 2, it returns twice as many pixels as if it were set to 1, for the same area covered and the same level of detail (map content is unchanged). Possible values: - 1 (default value),
- 2,
- 4 (available if owning a Google Maps APIs Premium Plan license).
