AGSSymbolReferenceProperties Class Reference

Description

Symbol properties that changes how symbols behave when attached to a renderer.

AGSSymbolReferenceProperties contains conditional properties that are not used directly by the symbol but rather by the renderer to change how a symbol is visualized based on the state of the view and the data. For example, the AGSSymbolReferenceProperties::minScale and AGSSymbolReferenceProperties::maxScale properties will be used by class breaks and unique value renderers to determine if a symbol break or unique value is visible at a certain scale. Additional symbols can be assigned as alternate symbols for the renderers. This allows the map author to control which symbol is displayed at certain scales.
