Map Widget Release

I made a new April resolution to start blogging reguarly again. The first step of that long journey begins now.

OpenStreetMap GPS Mapping Widget - 0.3

I just released v0.3 of osm-gps-map, the easy to use Gtk+ mapping widget. Highlights for this release include;

  • A new major contributor, Alberto Mardegan, who worked on many of the new features of this release. Thanks a lot Alberto!
  • Draw map tracks with Cairo by default.
  • Interpolate between zoom levels while waiting for a tile to download.
  • Stop using GET_PRIVATE, and cache priv* for performance.
  • Keep an extra border of images offscreen for smoother scrolling at the edges of the map.
  • Keep the last N tiles in memory to improve render performance (previously they were loaded from disk)
  • Add some new api; osm_gps_set_center, osm_gps_map_scroll.

Conduit Hacking

Hacking on Conduit continues, with much happyness for two reasons;

  • GNOME has moved to git! Wahoo! I owe the sysadmin team many beers, except for Jc2k who I know could not handle them anyway.
  • Conduit got a SOC project, congratulations Alexandre!
  • Work is ongoing to merge in the new configuration and settings serialization code.
  • More on this later, I promise…

    What would be interesting is a comparison with libchamplain. On features but also on goals. It looks like both projects share the same goal. And it would be cool to see Cairo tracks in libchamplain :-)

    Cool. Can we supply suggestions for May’s resolution? :-)

    If so, mine is: attend TVIC again and head over to the Christchurch Creative Space sessions: http://chchspace.nztech.org/

    Hi John,

    I’d like to use your widget to enable tagging photos with GPS coordinates in this: http://launchpad.net/phraymd

    Do you have a minimal python sample I could check out? (I couldn’t find one in the source but may have missed it…)

    cheers
    Damien

    Hi Damien,
    I’ve written a simple python app that does geotagging using this widget:
