[Theme] Voluntary

[Tapio]

John, the grid is still happening...

[john_percy]

@tapio Thanks for the report. This is a different effect and not one that appears on my device. I suspect it is resolution dependent.
Does this only happen at zoom 14? It looks like the border of a nature reserve area but the same defect is likely to happen at zoom 14 for water parks etc.
If it only happens at zoom 14 I can remove it at that zoom.

Yes exactly, only at ZL14, and in nature areas.
My screen res. is 1080x2244.
Other themes are also doing it. Elevate... Very bad in OSMap.

Thx. John, it's different now, but not gone.

Sadly I don't think there's much I can do about that which I think is due to overlapping semi transparent tiles used to show the nature reserve and similar.

OK... What I can add FZOam and ActiveRT5 do not have the issue.
Maybe you can point me to relevant code lines and I may search myself...

[john_percy]

I think the lines are to do with "protected areas" for nature reserve etc:

Code Select Expand

<rule cat="nocity" e="any" k="protect_class" v="pr_2|pr_3|pr_4|pr_5|pr_7|~" closed="yes" zoom-min="12" zoom-max="15">
<area fill="#14f0a000" />
</rule>
The area fill is semi-transparent so as not to block out the underlying features.
PS Because I can't reproduce the effect you are getting, I can't be sure whether it may be due to other semi transparent fills as well.

Hi Tapio,

In the OSMap theme there is an option "emphasise access land" which allows you to switch off the purple/gold outlines. I suspect this is caused by an issue with the underlying graphic's engine not being able to draw outlines correctly. It also looks like another element is outlining in black too...

does that help?

best regards,
Karl.

[Tapio]

IDK... with all options off, there's lines left... Will compare on PC with a decent editor, thx.

[john_percy]

It's the areas with outlines that are not being rendered correctly at this zoom level if they don't fit within a tile. In this example that's the woodland and the white area by the lake near Schrammberg. I'm afraid it's a known weakness of the implementation of the renderer.

Hmm... I am aware if this phenomenon and do relunctantly remove outlines at zoom levels below Z14, and this seems to works for all devices I have tested on so far... so I assumed it would be the same for other devices....

Does this mean outlines should be avoided for all large areas at Z14 too?  This would be a problem for my theme as outlines are a key aspect of the emulating the UK OS map style.

Is there any known workaround we could use at Z14? E.g. using delta offsets, etc?

[john_percy]

I don't know of any effective workarounds. I think this means that zoom 14 is out for outlined areas for this phone.

The latest versions of the Voluntary theme are now available in the first post in this thread.
They have been revised for the excellent V5 maps from OpenAndroMaps.

In V5 maps, hike, bike and MTB routes can be displayed and highlighted independently of each other. The highlighting can optionally be colour-coded in the Hiking and Cycling styles.

I have updated the naming conventions and file locations. If installing into Locus, please delete all earlier versions first (long press in theme manager).

I noticed it needs to reside in a subfolder under _themes (xml files cannot be directly in _themes/) - just mentioning. I think it was different before.
You always pack the unneeded windows lnk files btw 😉
