Migrating from 1.0.0. version
| Loading map |
- The map initialization code need to produce in the createVisicomMap () function.
You should independently determine this function (see example).
- Class VMapEngine replaced by VMap.
|
| Coordinates |
- Classes VPoint and VGeoPoint were removed from the engine. The system works only with geographical coordinates.
- The coordinates for all objects are transferred by structure {lng:
30.5112, lat:
50.4550}; (see
examples).
If your database is stored the local coordinates, they must be recalculated to the geographical coordinates.
It's carried out in two ways:
- By using XMLAPI 1.0.1
You must use the loc2geo method (see documentation)
- By using Maps API 1.0.0
You must use the VPoint.convertToGeoPoint() function (see documentation)
|
| Zoom levels |
- The zoom levels have changed slightly since change the projection of the map display.
But for the ukraine_ru (ua, en) database remained the same 12 zoom levels.
If you want to use the 18 zoom levels of the world you necessary to use the map world_ru (ua, en).
At the moment maps is only for the Ukraine and Belorussia.
|
| Adding/removing objects |
- From the VMap and
VLayer classes are removed by addMarker() and addPolyline() methods, etc.
Adding and deleting any object can be perform by add(obj) and remove(obj) functions.
|
| Working with events |
- Instead the VEvents object you must use appropriate methods of classes
VMap, VMarker
(see example).
|
| Markers |
- Using the marker has not significantly changed, but there are some features.
To open the information window you must execute the following code:
// the information window should already be set for the marker
marker.info(),visible(true);
map.repaint();
Hiding:
marker.info(),visible(false);
map.repaint();
- Also, information windows are simple objects, they can be added on the map without marker.
var info = new VInfoWindow({lng: ..., lat: ...}, "Текст");
map.add(info);
map.repaint();
If you add the information window by this example, it will always be displayed on the screen
Some behavior can be programmed using options (see description).
|
| Graphics |
- The VPolyline and VPolygone classes replaced by the VLine
and VArea
Using these classes has not significantly changed.
Parameters:
<html
xmlns:v=
"urn:schemas-microsoft-com:vml">
and the styles block
v\:* { behavior: url(#default#VML) }
are added automatically.
|
| Calculation of the route and remote services |
- These services are available only to registered users
(see description).
- In the new API version the calculation of the route available as supplement to the engine.
To do this, connect the JavaScript file from our server
(see. description).
- To calculate the route use the method of class
VRemoteCall.request().
All requests are considered as requests to XMLAPI method
getRoute.
|
| Others changes in the classes and methods |
- VBounds.
Instead, use VRect
- VMapEngine.resizeViewport().
Use method VMap.repaint().
This also checks the size of the map window.
