Properties

Property Details
alternateSymbols An array of symbol alternatives to a primary symbol. When alternative symbols are present, each symbol has minimum scale and maximum scale at which the symbol should be made visible. For any renderer that support alternate symbols, there is a primary symbol that has minimum and maximum scale defined. When rendering these renderer classes, the renderer should pick only one symbol at a given map scale for a given renderer class. The order of picking a symbol should be starting with primary symbol to check if it falls within the map's scale first before it iterates through alternate symbols in the array starting from 0. The renderer will then pick the first symbol that is visibile at current map scale. A symbol is visible if the map scale is greater than symbol's maximum scale and less than or equal to symbol's minimum scale.
description String value used to describe the drawn symbol.
label String value used to label the drawn symbol.
symbol An object used to display the value.
value String value indicating the unique value.
