Hi Steve, I changed it because of that screenshot and the remarks from Felix: http://gis.19327.n5.nabble.com/Overview2-branch-options-file-typo-tp5759855p... I wanted to have up to 8 levels for both the normal img and the overview map, and I found no problem with the overview map starting at level 0. I guess it would not be a problem for anyone to go back to the limit of 8 levels? Gerd Steve Ratcliffe wrote
Hi Gerd
need your help here. See screenshot from Felix at http://gis.19327.n5.nabble.com/Overview2-branch-options-file-typo-tp5759855p...
How do you think should the values look like for a configuration with - say 10 - levels, 5 in the normal maps and 5 in the overview map?
It should look like it does in the screenshot, with Zoom0=5, rather than Zoom0=0. But if you can't have a level greater than 8, then it would not be possible to have 10 levels in that case.
And what do I have to change?
I think that the overview map levels should just be LevelInfo.createFromString(levelSpec) but I see that used to be the case and then you changed it in r2592, so presumably some part of the code didn't deal with it properly. Can you recall the reason the change was made?
I don't know how to produce an overview map with other tools, and afaik I don't have one from Garmin.
A Garmin map that I own has the equivalent of
levels = 0:23, 1:21, 2:19 overview-levels = 2:17, 3:15, 4:13
The overview map also has two empty levels above those, rather than the usual one empty level.
