Hi Everyone,

I want to find the left,right,top, bottom latitude longitude from Map,

I have used the 6.0 API MapDimentions and MapField.

By using ,

  mapDimentions.getbottom(); //it will give me the bottom coordinate. or like getleft,gettop....

but it would not change when i moved the map.

i need a box coordinate or lat lon(all four) and also it will change when map moved..

Thanks,

You use convertFieldToWorld and use the 4 corners of the screen (in pixels) to get the appropriate map lat/lon coordinates.

Hi,

No.i am not using that but i can try for that,

thanks

any other comments.

Actually i am just test the OS 6.0 MapDimention class and its getboundry Method..

Hi ,

getboundry return the

left

right

below

and

top

cordiantes but it was static..

i want to get the four corner or four side data in dynamic manner like if i am scrolling the map than that data will be change by approciate  mapfield data..

Hi jprofitt,

How should i get the 4 corners lat lon using convertFieldToWorld?

can you give me some hint or comments?

Thanks..

Here's the first corner:

//Just creating a new Coordinates object, the values don't matter
Coordinates topLeft = new Coordinates(0,0,Float.NaN);
//The field point in pixels that you want to convert, this is where you put your four corners
XYPoint coords = new XYPoint(0, 0);
convertFieldToWorld(coords, topLeft);

After this topLeft will have your latitude and longitude of the top left corner of your map. Hope this helps!

hi jprofitt

Thanks for the Help..

Can you know about the MapDimention and getboundrybox() in 6.0 ?

 it will also give me a 4 side cordiante..

it will display just +- boundry of latititude..

eg. like -76.1234 to 76 1234

it will not change when i m move the map..

Thanks...

I've only used the MapField in 5.0 so unfortunately I'm not experienced with that object/method.
