Which layer is activated?

[anonymous]

OSM carto but it is the same for any of them. Z13 is the largest I can reach, and if, somehow, I end up in larger (like Z12 after selecting something based on a search) then I cannot zoom in or out.

[skyper]

Does it happen with a new/empty preferences? See Help/CommandLineOptions#Javaoptions.
Do you use default imagery settings?

[grinapo]

*&^%$#@!

It was imagery.tms.min_zoom_lvl. (Took considerable time to pinpoint.) I'm not sure why it limits the slippy, but it does. Something somewhere have set it to 13; I reset it to 2 and it's great again. :-(

[grinapo]

(As a sidenote, there is imagery.generic.min_zoom_lvl but it seems not to be used for that.)

[skyper]

Strange, I tested individual min_zoom per layer, and they do not influence slippy map. Think there are some enhancements possible:

• Own/separate settings for jmapviewer
• Visibility of general settings like imagery.tms.min_zoom_lvl and imagery.generic.min_zoom_lvl in the imagery preferences

[grinapo]

It is indeed strange since (as far as I remember correctly) I have tried to find all and any zoom related settings and turn the knobs, but eventually I have started *reset* settings *en masse*, and triangulated the culprit to that one, and it was indeed 13 and setting it to 2 indeed fixed it. I'm a bit puzzled myself, too.
But definitely it is confusing if that's used for jmapviewer, and separate config sounds like a good idea. You may reopen the ticket if you feel it have its merits...

Replying to skyper:

• Visibility of general settings like imagery.tms.min_zoom_lvl and imagery.generic.min_zoom_lvl in the imagery preferences

In the settings tab under imagery preferences, there is imagery.tms.min_zoom_lvl and imagery.tms.max_zoom_lvl but no imagery.generic.min_zoom_lvl. Maybe it is not used at all.
Below is a check box to add to jmapviewer but is is not obvious what it really does. Is it the whole entry or only settings which are added? Does it change default entries as it seems to be a general setting.
