Map viewer

<< < (3/3)

gbl08ma:
On my concept of map plugin, the user would put map files (and folders) on a specific folder of the DAP filesystem.
Then there could be a specific map index format for the plugin, but I think that parsing the locations file generated by GMapCatcher would be enough for now. If a specific map format is created someday, the plugin could act as a viewer and be able to "play" map indexes (and even route A-B instructions).

The navigation on the maps on iPods would be made with the four directional keys (to move left, right, up and down), and the scrollwheel to zoom, like on PNG viewer.

The biggest challenge on this plugin is putting the images together in the correct order with the correct zoom, be able to go to X,Y coordinates, and having a usable speed (PNG viewer is somewhat slow at decoding files). And in the future, it would also be nice if we could search for certain locations (villages, roads, streets).

Well, it seems I'm gonna checkout the SVN of Rockbox to see what I can do... wish me good luck and good work. Obviously if someone wants to join the work, they are greatly welcome :)

Chronon:
It would be a good idea, once you have posted a patch, to post a link here so that others can easily see what you have done and contribute if they want to.

gbl08ma:
Right now I got a whole bunch of ideas and no code yet :)

I'm setting up the development evironment, firstly I tried using Cygwin, but things were way too slow and gave lots of errors so now I just downloaded the VMWare disk image with the Rockbox development environment already setup... the problem is that I don't like using VMWare, so I'm going to use VirtualBox. But... the VirtualBox version I had installed is too outdated and has a problem reading the VMDK file... :)

Conclusion: I'm waiting for VirtualBox download to finish in order to read correctly (hopefully) the disk image, and when that finishes I'll need to set up the virtual machine (X settings, timezone, etc.). So, most likely I won't be able to code anything today, but to save time I'm already investigating how the map images are stored and organized. Fortunately everything seems to be done with numeric folders and files which makes pretty easy reading them on a DAP and showing them accordingly.
