Theme developing question

[Wojtas82]

After many test I was able to display parallel lines but sometimes parts of them are missing randomly like here.

When dy is set to 0 the whole route is displayed properly...

Code Select Expand

<rule e="way" k="osmc_color" v="red">
<line stroke="#FF0000" priority="40" force-draw="1" dy="16" stroke-linejoin="round" stroke-width="1" stroke-linecap="round" />
</rule>
Here's a link to OSM
http://www.openstreetmap.org/way/184490078
Any one knows solution?

@Wojtas82,

I made the same experiences and I think, it´s beacause "dy=" ist not usable with ways at this time. It´s a part of Mapsforge or Locus.

[Menion]

you found experimental feature . DY parameter for ways is currently in testing anyway it's not yet fully working, so don't use it

[Wojtas82]

Thanks! Any estimated date of implementation Menion
? 

[Menion]

it's not so simple, so don't expect it soon. Sorry.

[Wojtas82]

Oh thats a shame. This feature gives a lot of possibilities.

[Wojtas82]

That's where I found it:
https://code.google.com/p/mapsforge/wiki/RenderthemeV4
https://code.google.com/p/mapsforge/source/browse/mapsforge-map/src/main/resources/renderTheme-v4.xsd

[Menion]

Understand. Locus anyway do not use new version of MapsForge library, but just older version 0.3 with own improvements. So some new tags won't work in Locus. Sorry.

[jusc]

Thank you
@menion for implementig "dy for ways"
and thank you
@popej for creating a map that can be used for testing this new feature.
Unfortunately the "dy"-lines sometimes are on the right, sometimes on the left, or sometimes above or below the ways.
Depends it from the direction the way is drawn?

[Menion]

yes it depends. How this may happen (on your screenshot)? Is it possible, that lines are draw in OSM data in opposite direction here?

[jusc]

Yes the north part of thy way between Bühne and Suderode is drwan from north to south. the south path from south to north.
In the theme, the icn has dy="-10" for test.

[Menion]

hmm then there is nothing I can do with it now ...

[Wojtas82]

These parallel lines look very nice Jusc. Very useful when you have a hiking route and i.e. 2 bicycle routes. You can easly follow the route you want.

[jusc]

Yess, but you see the problem? Sometimes the lines change the side of the way, because it depends on how the way is drawn, from south to north, east to west or vice versa.
I hoped I could show parallel cycle routes (icn,ncn and so on) but I fear that is not really possible.

[Wojtas82]

Yeah, exactly I also noticed it. But I don't see a solution for this one unless dy parameter is added to the whole route not the part of the road. You know what I mean? I'm not sure. Maybe google "osmapa szlaki" and check this map I heard they tried to solve this problem?
