Getting Drawing Images (or URLs) for Non-Picture Marker Symbols

AdamPfister — Thu, 20 May 2010 00:09:06 GMT

Is there any way to make a request for a layer's drawing information and get back the actual image (or url) for a Simple Marker/Line/Polygon/etc symbol? This is easily done for a Picture Marker because the url is returned but for any other type, only the marker information is returned.

I'm trying to use this information to create a dynamic legend TOC so I would need some image to use unless there is a way to construct the graphic from the info and turn that into an image?

For example. This returns a nice image url to use:
http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Fire/Sheep/MapServer/0?f=pjson

This, however, only returns the graphic information:
http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Fire/Sheep/MapServer/1?f=pjson

What request is sent while using the Template Picker? That returns an image for Simple Symbols....

Thanks,
Adam

Did you ever figure this out? I'm attempting something similar and not having much luck.

Thanks!

I ended up using the esri.symbol.getShapeDescriptors() method. I followed the sample code here, http://help.arcgis.com/en/webapi/javascript/arcgis/help/jsapi/namespace_symbol.htm, to get it working correctly.

Good luck!
