Internal Render Theme - Where is osmarender.xml

[Charles Sweeney]

I see in mapsforge/map/rendertheme/InternalRenderTheme.java that the internal render theme is:

OSMARENDER("/osmarender/", "osmarender.xml");

I can't find "/osmarender/" or "osmarender.xml"

In Android Studio my project files show:

...\app\src\main\assets\renderthemes

assets.xml
assetssvg.xml
detailed.xml
driving.xml
onlybuildings.xml
osmarendernopng.xml

Where is osmarender.xml?

I am calling the internal render theme in BasicMapViewer with:

protected XmlRenderTheme getRenderTheme() {
        return InternalRenderTheme.OSMARENDER;
    }

...so if osmarender.xml isn't in my render themes, where is it?

I want to edit it so I can change the look of the map.

Osmarender theme is in the root of Mapsforge map module under osmarender folder.

Thank you for the very quick reply, Emux.

Okay, as it's in the mapsforge library it's not very convenient for me to edit it.

So I suppose I have to use an "external" render theme.  Would that be the ones I have here?:

...\app\src\main\assets\renderthemes

Would I put my own theme in there?

How would I call it?  I currently have:

return InternalRenderTheme.OSMARENDER;

You can use an external render theme from the file system or Assets folder.
Check the Samples for examples, i.e. RenderTheme4

[Emux]

The use of render theme from file system is:
new ExternalRenderTheme(renderThemeFile);

It's important to use the proper prefix for the resources in the render theme file (assets, file, jar), depending on the situation.

Again the examples describe it better.

Thank you very much, Emux.  I'll check it out.

Android Studio is giving me errors for osmarender.xml when using the latest render theme version.

For this:

xsi:schemaLocation="http://mapsforge.org/renderTheme ../renderTheme-v4.xsd"

...I get:

"Cannot resolve file 'renderTheme-v4.xsd'"

For this:

map-background-outside="#dddddd"

...I get:

"Attribute map-background-outside is not allowed here"

I am also getting some errors like:

For this:

<symbol id="monument" src="jar:symbols/monument.svg" />

...I get:

"Attribute id is not allowed here"

For this:

<caption symbol-id="monument" k="name" position="above"...

...I get:

"Attribute symbol-id is not allowed here" and "Attribute position is not allowed here"

Otherwise it seems to be working ok but doesn't look great with all the red error highlighting.

It tries to validate the xml render theme with its schema xsd file.

Either correct the path in render theme or move accordingly the xsd.
