-GPX Viewer upports starting/pausing, stopping and adding waypoints by automation with [[https://play.google.com/store/apps/details?id=net.dinglisch.android.taskerm|Tasker app]].
+GPX Viewer supports generating custom color and text icons for waypoints defined in gpx or kml files.
-This how to will explain how this could be automated with Tasker app:
-  - In Tasker add new task and add new action **System** -> **Send Intent** with these parameters:
+In gpx files you can define in <wpt> tag <extensions> tag, then <gpxwpx:WaypointExtension> tag into which you need to add <gpxwpx:icon> tag. These tags are not included in the gpx schema, so we are providing schema for this on this url: https://www.vecturagames.com/xmlschemas/GpxWaypointExtensionv1.xsd. Example:
-  Send Intent [
+  <wpt>
-    Action: android.intent.action.RUN
+    ...
-    Cat: None
+    <extensions>
-    Mime Type:
+      <gpxwpx:WaypointExtension>
-    Data:
+        <gpxwpx:icon>...</gpxwpx:icon>
-    Extra: android.intent.extra.TEXT:TRACK_RECORDING_ACTION_START_PAUSE
+      </gpxwpx:WaypointExtension>
-    Extra:
+    </extensions>
-    Extra:
+    ...
-    Package: com.vecturagames.android.app.gpxviewer.pro
+  </wpt>
-    Class:
-    Target: Activity ]
-For starting track recording add **android.intent.extra.TEXT** with parameter **TRACK_RECORDING_ACTION_START_PAUSE**, for stopping track recording change it to **TRACK_RECORDING_ACTION_STOP** and for adding waypoint change it to **TRACK_RECORDING_ACTION_WAYPOINT**.
+Inside <gpxwpx:icon> and </gpxwpx:icon> tags instead of ... you can write functions:
+  * **color_marker(color)** - instead of color you need to write the color in RGB format, for example #aab51c
+  * **text_marker(string)** - instead of string you need to write a maximum of three characters and a minimum one character, for example 100
+Example for **color_marker(color)**:
+  <wpt>
+    ...
+    <extensions>
+      <gpxwpx:WaypointExtension>
+        <gpxwpx:icon>color_marker(#aab51c)</gpxwpx:icon>
+      </gpxwpx:WaypointExtension>
+    </extensions>
+    ...
+  </wpt>

+Example for **text_marker(string)**:
+  <wpt>
+    ...
+    <extensions>
+      <gpxwpx:WaypointExtension>
+        <gpxwpx:icon>text_marker(100)</gpxwpx:icon>
+      </gpxwpx:WaypointExtension>
+    </extensions>
