Or perhaps drawing the surrounding parts from a lower resolution upscaled? That way, slight movements of the screen wouldn't necessitate a redraw.
The black isn't fun, especially when we're just making slight adjustments; if it's necessary, we'll understand.
The impact would be 9 times the amount of memory required, and 9 times the amount of CPU time to render a view. The cost-benefit ratio is not worthwhile, in my opinion, especially when the black is only ever visible when you're manually panning (i.e. not Auto-Center).

If I don't use auto download on the map and go to the middle of sweden, and go to manage maps to download a map for the area manually, and just press ok, it won't download a map for the area, but rather one quite a bit west of the location, in the atlantic. If you change the "E" to a "W" in the Longitude for both top left and bottom right it will download for the right area however. This bug was there in 1.4 as well, and possibly earlier versions. Its easier to see at the more zoomed in zoom levels, as if you go too far out you might get the area you are trying to get as well as the individual images cover larger areas. I think this affects a large portion of europe, possibly everything east of the point of the W/E switch. If you use auto download it will get the correct location each time.
Interesting. I never noticed this before. I'll see if I can reproduce it and find a fix. Thanks.

Not at the moment. Unfortunately, there is a lot of code that relies on "0" being the minimum zoom. In order to support zoom levels below 0, I have to change all that code. It may happen some day, but it probably won't be soon.

Hmm. I can't reproduce this. Maemo Mapper starts fine for me when in offline mode, even with auto-download on. Are you able to reproduce the problem, or did it just happen the one time?

You shouldn't have to restart your device after upgrading Maemo Mapper.

I think I still have those buttons mapped to, e.g., "Pan East" instead of "Pan Right." I'll fix that.

It seems it only happened the once. I cannot reproduce and I have not rebooted the N800 since installing MM 2.0 :)

OK thats great, in a moment I thought that might be why I had the crash when in offline mode but as I cannot repeat :)

Re: Maemo Mapper v2.0
 
Well, I just ran 2.0 on the interstate for 300 miles. The new features are quite cool, especially the map rotation. But, it's a big drop in stability versus 1.4 (certaintly understandable ;)). I had more than a dozen crashes over the whole trip (which is a bit of a pain at 80mph :D), now, since I was cruising down the interstate, I couldn't really say for sure but I think it may have failed on map downloads. I pre-cached along the route before I left this morning, but I may have gone out of the cached zoomed levels and I don't think it liked trying to fetch over the EDGE connection on my phone.

Okay, cool, but I'd suggest that your project is bigger than you think it is. I've used Maemo-Mapper extensively, and to great benefit, both with and without GPS. But I've never used it in a car (yet). Manually is the only way I pan. Frankly, I'd be willing to eat a much larger delay from time to time instead of rebuilding the screen every time I pan. Maybe not 2400x1440, but but perhaps 1312x992?

Anyway, thanks again, and congratulations on your release.

I understand completely. It is such a minor thing to me that I cant even consider it a "gripe" by any means.

Thanks again for an excellent product and your response.

The zoomsteps below 0 also affects the usability of MM in the car. In my optinion you can't use MM while driving because of the concentration which is needed for the small maps (even on zoom step 0). too bad. the new release is a large step in the right direction. so, i hoped to sell my tomtom because of the new release. but this has to wait until the maps are larger...

another thing are the black areas while moving the maps. as mentioned, this is not just really annoying but it really slows you down while moving. you could move by far faster with the old method. so perhaps you can add an option to choose the old method or the new one for navigating.

there is another question: perhaps this is because of the new moving method, but the new map database seems to be much slower than the pure maps system. so, why was this changed?

a cool thing is, that you can choose indiviual icons for pois. but can you use a general replacement for poi icons if you didn't select an indiviual icon, so that we never have to see the ugly purple squares? ;)

besides my moaning and groaning, excellent work :)
