+## How to contribute
+
+As an open source project, we welcome new contributors and appreciate your help.
+
+Before you start working on an unresolved issue or try to implement a new feature, please contact us via the Discussions. We will then discuss the best way to realize your proposal and figure out how we can help you to get started quickly.
+
+If you are only requesting a small change in the code, you may attach a patch file to the corresponding issue, but it is best to create a pull request on Github. Make sure that your patch is derived from the latest version in our **master** repository, otherwise we might be unable to apply it. Important is to keep pull requests simple with one feature in each. Please follow our code and style conventions.
+
+Also please keep the pull request commits squashed, in order to avoid the clutter in repository and have only the finally changed files together. One way is described [here](http://gitready.com/advanced/2009/02/10/squashing-commits-with-rebase.html).
+
+Regarding code make sure your IDE uses UTF-8 encoding, for indentation 4 spaces (no tabs) and follow the conventions you already see in the code.
+
+Please note that the VTM project is licenced under the [GNU LGPL3 licence](http://www.gnu.org/licenses/lgpl.html). Thus, all your contributions are going to be published under this license.

+# RenderTheme
+
+This article describes how to use XML-based render-themes to style maps.
+
+## Introduction
+
+A render-theme is an XML file which contains rules and rendering instructions. Such files can be used to customize the visual style of the rendered map. The vtm map library comes with built-in render-themes similar to the [Osmarender](http://wiki.openstreetmap.org/wiki/Osmarender) style. External render-theme files are also supported and can be activated via the `map.setTheme(ThemeLoader.load(File))` method at runtime.
+
+Syntax and semantics of render-theme files are similar but not identical to [Osmarender rules](http://wiki.openstreetmap.org/wiki/Osmarender/Rules). A formal render-theme description exists as an *XML schema document*, it can be found in the [repository](https://github.com/mapsforge/vtm/blob/master/resources/rendertheme.xsd).
+
+It is always recommended to study the [default](https://github.com/mapsforge/vtm/blob/master/vtm-themes/resources/assets/vtm/default.xml) built-in render theme.
+
+## Rules
+
+A rule element `<m/>` (_match_) has several attributes to specify which map elements the rule matches. Non of them is required.
+
+|**Attribute**|**Valid values**|**Description**|**Default**|
+|-------------|----------------|---------------|------------|
+|e|<ul><li>node</li><li>way</li><li>any</li></ul>|Defines which map element type will be matched.|*any*|
+|k|[string](http://www.w3.org/TR/xmlschema-2/#string)|The key of the tile source tag. <ul><li>A vertical bar "`\|`" can be used to specify multiple keys.</li>|any key|
+|v|[string](http://www.w3.org/TR/xmlschema-2/#string)|The value of the tile source tag. <ul><li>A vertical bar "`\|`" can be used to specify multiple values.</li><li>A minus sign "`-`" excludes the other values after "`\|`". It never works alone.</li><li>A tilde "`~`" matches if the map element does not have a tag with the specified key.</li>|any value|
+|closed|<ul><li>yes</li><li>no</li><li>any</li></ul>|Defines which ways will be matched. A way is considered as closed if its first node and its last node are equal.|*any*|
+|select|<ul><li>first</li><li>when-matched</li><li>any</li></ul>|<ul><li>Only add the first matching sub-rule in this rule section (the others are ignored)</li><li>Select all matches of the enclosing rule section</li><li>Select all (whether it was matched or not)</li></ul>|*any*|
+|zoom-min|[unsigned byte](http://www.w3.org/TR/xmlschema-2/#unsignedByte)|The minimum zoom level on which the rule will be matched.|*0*|
+|zoom-max|[unsigned byte](http://www.w3.org/TR/xmlschema-2/#unsignedByte)|The maximum zoom level on which the rule will be matched.|*127*|
+
+Rules can be nested to any level of depth. This can be used to define rendering instructions which depend on multiple rules. It may also be used to structure complex declarations and to avoid redundancy:
+
+```xml
+<m e="way" closed="no">
+    <m k="highway" v="motorway">
+        <m k="tunnel" v="true|yes">
+            …
+        </m>
+        <m k="tunnel" v="~|no|false">
+            …
+        </m>
+    </m>
+</m>
+```
+
+
+Here is an example how to use the `select` attribute. The symbol is shown. The **bold** caption isn't visible cause only the first matched sub-rule is considered. The _italic_ caption is displayed as it was selected by the first sub-rule.
+
+```xml
+<m k="railway" v="halt|tram_stop" zoom-min="15" select="first">
+    <m v="tram_stop">
+        <symbol src="assets:symbols/transport/tram_stop.svg" />
+    </m>
+    <m v="tram_stop">
+        <caption style="bold" dy="20" fill="#af3a3a" k="name" size="12"/>
+    </m>
+    <m select="when-matched">
+        <caption style="italic" dy="-20" fill="#222222" k="name" size="12"/>
+    </m>
+</m>
+```
+
+## Rendering Instructions
+
+A rendering instruction specifies how a map element is drawn. Each rule element might include any number of rendering instructions. Except for labels and symbols, all rendering instructions are drawn on the map in the order of their definition.
+
+At the moment, the following rendering instructions are available:
+
+ - `area`
+ - `caption`
+ - `circle`
+ - `line`
+ - `outline`
+ - `lineSymbol`
+ - `text`
+ - `extrusion`
+ - `symbol`
+
+## Header Elements
+ 
+The following header elements can be used:
+ - `map-background`: a color value to set the color of a blank tile. This should not be used to set the color of the sea or land. Default is `#FFFFFF`.
+ - `base-stroke-width`: set the basic width of strokes. Default is `1`.
+ - `base-text-scale`: set the overall text scale. Default is `1`.
+
+```xml
+<?xml version="1.0" encoding="UTF-8"?>
+<rendertheme xmlns="http://opensciencemap.org/rendertheme" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+    xsi:schemaLocation="http://opensciencemap.org/rendertheme https://raw.githubusercontent.com/mapsforge/vtm/master/resources/rendertheme.xsd" version="1" map-background="#FFFCFA">
+    …
+</rendertheme>
+```
+
+## Texts and Captions
+
+The most common attributes for textual styling:
+
+|**Attribute**|**Valid values**|**Description**|**Default**|
+|-------------|----------------|---------------|-----------|
+|font-family|*default*, *default_bold*, *monospace*, *sans_serif*, *serif*, *thin*, *light*, *medium*, *black*, *condensed*|Set font family|*default*|
+|style|*bold*, *bold_italic*, *italic*, *normal*|Set font style|*normal*|
+|size|non negative [float](https://www.w3.org/TR/xmlschema-2/#float)|Set font size|*0*|
+|fill|[color](https://www.w3.org/TR/css-color-4)|Set fill color|*#000000*|
+|stroke|[color](https://www.w3.org/TR/css-color-4)|Set stroke color|*#000000*|
+|stroke-width|non negative [float](https://www.w3.org/TR/xmlschema-2/#float)|Set stroke width|*0*|
+|dy|[float](https://www.w3.org/TR/xmlschema-2/#float)|Offset in vertical direction|*0*|
+
+## Styles
+
+There are different possibilities to simplify and accelerate map styling or changing styles.
+
+### Style patterns
+
+If you want to use a specific style multiple times you not have to rewrite it for each text, line, area or symbol rule.
+If you define a style set an `id` and use it with `use` in your rendering instructions:
+ - `style-text`
+ - `style-line`
+ - `style-area`
+ - `style-symbol`
+ 
+This example styles all areas with the_residential_ style, which haven't the `highway` or `building` key.
+ 
+```xml
+<style-area fade="11" fill="#e8e7e3" id="residential" />
+
+<m closed="yes" e="way" k="highway|building" v="~">
+    <m v="residential|commercial|retail|farmyard">
+        <area use="residential" />
+    </m>
+</m>
+```
+
+### Stylemenus
+
+The **stylemenu** allows you to selectively turn rules on and off, in effect defining multiple layers in a map that can be controlled individually. 
+
+To make use of style menus, you will first need to group the elements of your map into categories by attaching a **cat** element to them.
+
+```xml
+<m cat="areas" e="way" k="landuse" v="landfill|quarry" zoom-min="14">
+```
+
+The same cat tag can be given to as many elements as you like, but each element can only have one cat tag.
+However, this does not limit your ability to group elements, as in the style definitions, multiple categories can be combined into one layer. 
+
+You can think about the cat tag as a switch that switches all elements in the rendertheme below it either on or off. If a category is turned off, all elements below it become invisible. If a category is turned on, all elements below become visible (unless they are themselves controlled via a category which is turned off).
+
+Layers are combinations of categories that can be toggled on and off together and other layers (via **overlay**) that can be toggled on and off individually. In general, categories are not visible to a map user, but layers are. To make layers more user friendly, they can be named with the name tag in various languages.
+
+```xml
+<layer id="public_transport" visible="true">
+    <name lang="de" value="Öffentlicher Verkehr"/>
+    <name lang="en" value="Public Transport"/>
+    <name lang="es" value="Transporte público"/>
+    <name lang="fr" value="Transport public"/>
+    <cat id="public_transport"/>
+    <cat id="rail"/>
+</layer>
+```
+
+A set of layer definitions makes up a style:
+
+```xml
+<stylemenu id="r4menu" defaultvalue="terrain" defaultlang="en">
+    <layer id="shopping" visible="true">
+        <name lang="de" value="Shopping"/>
+        <name lang="en" value="Shopping"/>
+        <name lang="es" value="Tiendas"/>
+        <name lang="fr" value="Shopping"/>
+        <cat id="shopping"/>
+    </layer>
+
+    <layer id="terrain" visible="true">
+        <name lang="de" value="Topographischer Hintergrund"/>
+        <name lang="en" value="Topographic Colours"/>
+        <name lang="es" value="Colores topográficos"/>
+        <name lang="fr" value="Couleurs topographiques"/>
+        <cat id="topo"/>
+    </layer>
+</stylemenu>
+```
+
+The **visible** attribute is meant to indicate which of the layers are visible in the user interface. Layers where visible is set to false should not be seen by a user, and are thus useful to build base-layers of common categories from which then user-visible layers can be inherited, like this:
+
+```xml
+<layer id="base">
+    <cat id="roads"/>
+    <cat id="waterbodies"/>
+    <cat id="landuse"/>
+    <cat id="places"/>
+    <overlay id="emergency"/>
+    <overlay id="food"/>
+</layer>
+
+<layer id="simple" parent="base" visible="true">
+    <name lang="de" value="Auto"/>
+    <name lang="en" value="Driving"/>
+    <name lang="es" value="Conducción"/>
+    <name lang="fr" value="Conduite"/>
+    <cat id="transport"/>
+    <cat id="barrier"/>
+    <cat id="driving"/>
+    <overlay id="parking"/>
+    <overlay id="shopping"/>
+</layer>
+
+<layer id="standard" parent="base" visible="true">
+    <name lang="de" value="Stadt"/>
+    <name lang="en" value="City"/>
+    <name lang="es" value="City"/>
+    <name lang="fr" value="Ville"/>
+    <cat id="areas"/>
+    <overlay id="tourism"/>
+    <overlay id="sports"/>
+    <overlay id="amenities"/>
+    <overlay id="buildings"/>
+    <overlay id="public_transport"/>
+    <overlay id="accommodation"/>
+    <overlay id="shopping"/>
+</layer>
+```
+
+To turn layers on by default, add the **enabled=true** attribute. In this case, buildings should be by default visible, while parking related elements not:
+
+```xml
+<layer id="parking">
+    <name lang="de" value="Parkplätze"/>
+    <name lang="en" value="Parking"/>
+    <name lang="es" value="Aparcamiento"/>
+    <name lang="fr" value="Parking"/>
+    <cat id="parking"/>
+</layer>
+
+<layer enabled="true" id="buildings">
+    <name lang="de" value="Gebäude"/>
+    <name lang="en" value="Buildings"/>
+    <name lang="es" value="Edificios"/>
+    <name lang="fr" value="Bâtiments"/>
+    <cat id="buildings"/>
+</layer>
+```
+
+#### Map Integration
+
+The [Playground](https://github.com/mapsforge/vtm/blob/master/vtm-playground/src/org/oscim/test/MapsforgeStyleTest.java) and [Android](https://github.com/mapsforge/vtm/blob/master/vtm-android-example/src/org/oscim/android/test/MapsforgeStyleActivity.java) Samples app have a completely worked style menu.
+When a rendertheme is parsed, the style menu definitons are parsed and a callback is made into the application giving it access to the stylemenu definitions. 
+
+On Android, the stylemenus can thus be converted into standard Android settings, providing a seamless integration of the rendertheme definitions that do not require changes every time the rendertheme changes. There is an example on how to do this in the Samples app of Mapsforge, see the [Settings.java](https://github.com/mapsforge/mapsforge/blob/master/mapsforge-samples-android/src/main/java/org/mapsforge/samples/android/Settings.java) file in Mapsforge repository.
+
+## Priorities
+
+Labels and icons are drawn in order of priority. The default (and highest) priority is 0, so anything with a priority higher than 0 will only be drawn if the space is not yet taken up or has a lower priority value than its colliding elements.
+
+_VTM priorities have the opposite meaning to the Mapsforge render-theme priorities._
+
+```xml
+<m e="node" k="place" v="town" zoom-min="8">
+    <caption priority="2" k="name" style="bold" size="14" fill="#333380" stroke="#FFFFFF" stroke-width="2.0"/>
+</m>
+<m e="node" k="place" v="city" zoom-min="6" zoom-max="6">
+    <caption priority="0" k="name" style="bold" size="11" fill="#333380" stroke="#FFFFFF" stroke-width="2.0"/>
+</m>
+```
+
+## Symbols
+
+Symbols can be either defined in the raster PNG format or as vector graphics in SVG format. VTM uses libraries for [Android](https://github.com/BigBadaboom/androidsvg) and [Java](https://github.com/blackears/svgSalamander) that support a large subset of the [Tiny SVG](http://www.w3.org/TR/SVGTiny12/index.html) specification.
+
+### SVG Scaling
+
+SVG resources can be automatically scaled to accommodate different device resolutions.
+
+The options available are:
+
+- If no size is given, a svg is rendered to a 20x20px multiplied by the device scale factor and any user adjustments.
+- symbol-percent: the svg is rendered as a percentage size of its default size. This is the best way to make certain svg smaller or bigger than others.
+- symbol-width and/or symbol-height: additional parameters give the absolute pixel size for the symbol, again adjusted by the scale factors. If only one dimension is set, the other is calculated from aspect ratio.
+
+### SVG Icon Design 
+
+If you want to know how to design your own icons, you can have a look at Google's [Material Design](https://material.io/design/iconography/system-icons.html) conventions.
+To keep SVG sizes down, it is advisable to make use of the reuse facilities within SVG files and to remove any unneccessary comments and metadata.

+### Desktop
+
+To run the desktop samples can use the Gradle `run` task.
+
+e.g. for `vtm-playground` can change the [mainClassName](../vtm-playground/build.gradle) to run each sample and pass args:
+```groovy
+./gradlew :vtm-playground:run -Pargs=/path/to/map
+```
+
+To create a standalone executable jar, adapt the main class in [build gradle](../vtm-playground/build.gradle), then run:
+```groovy
+./gradlew :vtm-playground:fatJar
+```
+The jar file can be found in `build/libs` folder. Depending on the main class, pass args on execution via command line:
+```
+java -jar vtm-playground-master-SNAPSHOT-jar-with-dependencies.jar /path/to/map
+```
+
+To change the libGDX backend can replace the dependency: `vtm-desktop-lwjgl` or `vtm-desktop-lwjgl3`.

+### iOS implementation
+
+RoboVm needs the native libs / frameworks to create a build.
+
+Create a copy task into your iOS **build.gradle** and add the dependencies.
+
+```groovy
+configurations { natives }
+
+dependencies {
+    compile "org.mapsforge:vtm-ios:[CURRENT-VERSION]"
+    natives "org.mapsforge:vtm-ios:[CURRENT-VERSION]:natives"
+    ...
+}
+
+// Called every time Gradle gets executed. Takes the native dependencies of
+// the 'natives' configuration and extracts them to the proper build folders
+// so they get packed with the IPA.
+task copyNatives() {
+    file("build/native/").mkdirs();
+    configurations.natives.files.each { jar ->
+        def outputDir = null
+        if (jar.name.endsWith("natives.jar")) outputDir = file("build/native/")
+        if (outputDir != null) {
+            copy {
+                from zipTree(jar)
+                into outputDir
+            }
+        }
+    }
+}
+```
+
+Now you can configure your `robovm.xml` to implement the vtm-natives and the SVG-Framework.
+
+```xml
+<libs>
+    <lib>z</lib>
+    <lib>build/native/libvtm-jni.a</lib>  <!--vtm native -->
+</libs>
+<frameworkPaths>
+    <path>build/native</path>  <!--SVGgh framework path -->

+<frameworks>
+    <framework>SVGgh</framework> <!--SVGgh framework name -->
+    <framework>UIKit</framework>
+    <framework>OpenGLES</framework>

+    <framework>OpenAL</framework>
+    <framework>AudioToolbox</framework>
+    <framework>AVFoundation</framework>
+</frameworks>
+```
+
+Remember the implementation of a iOS framework is possible since iOS 8.
+So we must set the min iOS-Version at `Info.plist.xml`.
+
+```xml
+<dict>
+    <key>MinimumOSVersion</key>
+    <string>8.0</string>
+    ...

+`./gradlew :vtm-web-app:farmRun` will run standalone web server at port 8080.
+
+Then go to [http://localhost:8080/vtm-web-app](http://localhost:8080/vtm-web-app) in the web browser to see the map.
+
+Hold right mouse button to change view direction.
+
+#### Debugging GWT app
+
+Using GWT SuperDevMode is the recommended way for development. Debugging in IDE is often not possible.
+
+For an introduction see [GWT](http://www.gwtproject.org/articles/superdevmode.html) and [libGDX](http://www.badlogicgames.com/wordpress/?p=3073) documentations.
+
+- Serve the website as usual with `./gradlew :vtm-web-app:farmRun` command.
+
+- The codeserver must be executed on another shell.
+```bash
+export _JAVA_OPTIONS="-Xmx1024m"
+./gradlew :vtm-web-app:gwtSuperDev
+```
+
+- Open the link of codeserver: `The code server is ready at http://127.0.0.1:xxxx/`
+
+- Drag the two bookmarklets to your browser's bookmark bar.
+
+- Visit your [web page](http://localhost:8080/vtm-web-app) and click **Dev Mode On** to start development mode.
+
+- Press **F12** to open the developer tools of your browser. Now you can debug your code under **Sources**.

+ * legacy C and C++ applications to Java and to target the needs of the
+ * community who, at present, wish to do their own native rendering to canvases
+ * for performance reasons.  Standard extensions such as Java3D also require a
+ * means to access the underlying native data structures of AWT.
+ *
+ * There may be future extensions to this API depending on demand.
+ *
+ * A VM does not have to implement this API in order to pass the JCK.
+ * It is recommended, however, that this API is implemented on VMs that support

+ *
+ * Since this is a native API, any program which uses it cannot be considered
+ * 100% pure java.
