comment: elm_map_convert_canvas_into_geo() -> should rename to be more efl strict oo like: elm_map_canvas_to_geo_convert() while i'm at it: elm_map_utils_rotate_coord() should be elm_map_utils_coord_rotate() could you fix this? :) > After consideration, I think that elm_map_utils_size_get() and > elm_map_utils_region_get() is not needed for users. because only > functions related to geographic coordinates are only concern of users. > And converting func. from canvas to geo is needed for finding exact > geo-coordinates in canvas area. > So, I have modified patches. > > Anyway, no one may interested in elm_maps... > Please review this patch....plz... > > 2012/1/2 Bluezery <ohpo...@gmail.com>: > > Hi, > > > > In my point of view, elm_map did not consider zooming & rotation by > > using Evas_Map initially. > > There are no problems if you use only elm_map_zoom_set().
