_layer

_layer( o )

_layer internal class used to store map layers within a map. Map layers track visibility of the layer in the user interface. Parameters are passed as an object with the following attributes: name - string, the name of the layer visible - boolean, the current state of the layer (true is visible) opacity - integer, between 0 (transparent) and 100 (opaque), controls opacity of the layer as a whole imageformat - string, the format to request the tiles in for this layer. Can be used to optimize file sizes for different layer types by using GIF for images with fewer colours and JPEG or PNG24 for high-colour layers (such as raster imagery). queryable - boolean, is the layer queryable? This is different from the layer being included in queries. bQueryable marks a layer as being capable of being queried. The layer also has to have it's query state turned on using setQueryable scales - array to containing the layer visibility for each scale force - force layer ***************************************************************************
