Scrollable as is is not possible, thus the term "static". You need to download another picture.

Yes,
i know that i have to download a new map.
Actually what i do not know is how to ge the coordinate of latitude and longitude of the center of the new static map that i have to download. Any idea?

Uou must known yourself which for coordinates you request the map. They are in the URL.

Hi,

I've found this JS function that could help you:

http://www.polyarc.us/adjust.js
where:

"x" is Latitude in fractional degrees
"y" is Longitude in fractional degrees
"deltaX" is positive / negative Latitude adjustment in PIXELS
"deltaY" is positive / negative Longitude adjustment in PIXELS
"z" is zoom level

Hope it helps
Pit

Hi guys,
I'm not able anymore to retrieve the code because I've lost it since I did not program anymore but I can give you an important tip which I've learned from the boat-driving-license that is:
If you have a GPS point of coordinates:
LAT alpha= 41° yyy.zz ' N
LON deltha = 012° kkk.tt' E
you can estimate that
1 Minute of degree longitude= 1 International Nautical Miles = 1852m (http://en.wikipedia.org/wiki/Nautical_mile)

Please, watch out that latitude and longitude can be written either on decimal format (41.50 °N) or in Degrees, Minutes, Seconds (Es: 41° 30' 00'' N) and you can use that equation only for minute of degree. This means that if you have the coordinates in decimal format, you first have to convert it to degree, minutes, seconds.
The second remark is that that equation is valid only for short distances so you should not use it when the zoom of the map is very out.

You can use this equation to map the movement of the map in your display.
Good luck

If you want to minimise the number of bytes downloaded, you would be better off using a proper Java ME library to display a scrolling map. e.g. look at:
http://www.developer.nokia.com/Devel...I_for_Java_ME/

If you insist on using a static mapping library for a dynamic mapping using case, you could look at:
http://www.developer.nokia.com/Commu...I_with_Java_ME

The only dynamic maps within the Map Image API rely in JavaScript, but this link may prove useful:
