the pixel origin should be at the top left right?
How can I assume the screen size then?
if (0,0) is the center, screenWidth and screenHeight would be where?
I was assuming that:
mymap.getProjection().fromPixels(0, 0) would give me the top left
mymap.getProjection().fromPixels(screenwidth, screenheight) would give
me the bottom right
and from there I could take the latitude and longitude of each
corner.. is that possible?
For example:
GeoPoint X = mapView.getProjection.fromPixeis(0,0);
GeoPoint Y = mapView.getProjection.fromPixeis(screenWidth,screenHeight);
X.getLatitude(); Would give me the top latitude
Y.getLatitude(); Would give me the bottom latitude
X.getLongitude(); Would give me the left longitude
Y.getLongitude(); Would give me the right longitude
And with those values I have the area of the screen with the
boundaries latitude/longitude wise which is the values that I need to
perform my algorithm.

I don't see a problem there, except that the pixel origin appears to
be at the center of the map view!
