[ka-Map-users] GeoCordinate

[jerome.teisseire at free.fr]

I want to show the coordinate of each tile, in debug mode,
in tile.php :
 /* debugging stuff */
                if ($bDebug)
                {
  imagestring ( $oTile, 3, 10, 30, "minx:"($real_minx)." miny
".($real_miny)."maxx:"($real_maxx)." maxy ".($real_maxy)", $black );

How can i calculate the real coordinate ? real_minx, real_miny ...
