size property

The symbol size.

The measurement unit for this property is in device-independent pixels (DIPs) by default. To use meters in 3D scenes instead, set the MultilayerSymbol.sceneSizeUnit property to SymbolSizeUnits.meters. This switches the interpretation of the size from DIPs to meters.

When getting the size from a multilayer point symbol, the value reported is the largest size of all the symbol layers it contains. The symbol size is updated when its symbol layer sizes change (if there is a new largest layer size). When setting a new size at the point symbol level, the size of the largest symbol layer is given the provided value, and all the smaller layers are sized proportionately. An individual symbol layer can be given a specific size without affecting the other layers.
