User Case
In addition to downloading map images from the OSM server, Locations also supports local maps, which can be downloaded through the Installer. You can also create your own maps if your city is not available. For more information, refer to the [Offline Maps] section below.
Views
- MAP view
Use the MAP view to manage Tags with options to save, edit or send. MAP view also allows users to browse maps with zoom in and zoom out for accurate locating. If you get lost while browsing, simply tap the REFRESH button to return to your current position. It's that easy.
- LIST view
LIST view is a a centralized place to view all of your Tags. The LIST view is a combination of your own saved Tags and Tags received by friends. Selecting a Tag takes you to the exact position of the Tag in the MAP view.
Architecture
Splinter is an UI application, communicating with diversity-daemon dbus interface to get all the data it needs.
What Splinter does and shows is based on and through diversity-daemon, like tag management and sharing, map downloading, gps status, etc.
Design
Splinter used EFL library to implement the UI. Sync with Diversity-daemon, Splinter has objects, world, viewport concept. There is a dbus wrapper layer for diversity daemon. In pure UI part, we have widgets like dialogs, menus, different objects like tags, map tilesets, etc.
In control part, we have a nav object for controlling the navigation, showing the tileset.
Create Offline Maps
Splinter comes with a tool called splinter-map-pack. It can be used to pack tile images downloaded from OSM server into a map package:
splinter-map-pack /tmp/diversity-maps my_map.eet
Place my_map.eet in either of the directories
/usr/share/splinter/maps /media/card/splinter-maps
and Splinter will find it automatically.
