Custom Graphics

TalShapiro — Fri, 23 Nov 2012 07:01:45 GMT

Hello,
Hope someone could help me with the following issue -

I need to draw a pie slice Graphic in a GraphicsLayer (See attached picture). How can this be accomplished?
More generally, how are polyline/polygon Geometry MapPoints being translated to the Fill/Line symbol Path (named "Element").

Many thanks!

I also need to draw my custom Graphics such as a ring or bulleye.
How can customize the graphics?

Hi,

You can use a ControlTemplate to provide a custom symbol - see http://resources.arcgis.com/en/help/runtime-wpf/apiref/index.html?ESRI.ArcGIS.Client~ESRI.ArcGIS.Client.Symbols.Symbol.html for more information.

Cheers

Hi Mike,
Drawing a custom marker or changing attributes of a Line/Fill default Path is pretty straightforward.
My goal, however, is to generate a custom path based on some custom geometry. The path should scale by zoom in/out.

Could you advise?

Hi,

In that case you can simply programmatically build up Polyline geometries by specifying their Paths property: http://resources.arcgis.com/en/help/runtime-wpf/apiref/index.html?ESRI.ArcGIS.Client~ESRI.ArcGIS.Client.Geometry.Polyline~Paths.html.

But what if I don't need to draw a simple polyline/polygon?
I need to draw a path with an arc - see attached picture above.

The default mechanism that translates the Geometry MapPoints collection to a polyline/polygon Path doesn't seem to suite my needs.
My question is if there's a way to customize this mechanism and draw custom paths on the map.
