I'm using ArcGIS 10 and the .NET SDK. For each feature in a feature layer, is there a way to selectively flip the feature horizontally? I want to loop through the features, and for each feature decide whether to horizontally flip the feature or not. The features are point symbols. I know how to access to the IFeature interface of each feature. Where do I go from here? Do I need to add a representation rule to the features that I want to flip? Would that work on a per feature basis? Thanks for any help.
