Because most map image file is very big, from several MB to tens MB, it is very inconvenient to view map with ordinary image viewer, especially for embedded system like PDA and mobile phone.
This program is developed to facilitate map viewing, the basic idea behind it is:
- The big map image file is splitted into many small image files, loaded on demand to reduce memory requirement.
- The big map image file is pre-scaled too, because scaling a big image file is also a memory/CPU hungry task.
