+ | ==== Layer Attributes ==== | ||
+ | |||
+ | The layer attributes((Currently, only the layer name is the only layer specific attribute returned.)) are returned in a second table. This table has the following format. | ||
+ | |||
+ | ^ Column Name ^ Key or Data? ^ Column Type ^ Description ^ | ||
+ | | "Layer_Index" | Key | Real | The index of the corresponding layer | | ||
+ | | "Layer_Name" | Key | String | The name of the corresponding layer | | ||
