Just remember if you turn on scale symbols you must also set the reference scale for the map IMap::ReferenceScale or the ScaleSymbols property is meaningless. | |

If I draw with a size of 25 on a foot-dimensioned map, the marker is 25 feet across, which renders as a varying number of pixels depending upon the map zoom level. What I want is a constant number of pixels independent of map zoom. I was told this wasn't possible with IGraphicsContainer, and I needed to create a FeatureLayer with ScaleSymbols turned off. | |

| Aug 11, 2016 at 14:14 | comment | added | Jeff Dege | I tried that, but the markers scaled to the map - they drew at a fixed size relative to the map, and scaled in size as the map zoomed in and out. | |

Typically this is done using IGraphicsContainer to add IMarkerElements to the map. See "Add Graphic to Map" here

And I need the locations of these markers and labels is determined by code, rather than in a geodatabase, shapefile, etc. | |
