Level
Constructs a level set with specified parameters.
Parameters
the sector spanned by this level set
the origin for this level set
the geographic width and height of tiles in the first level (the lowest resolution) of the level set
the number of levels in the level set
the height in pixels of images associated with tiles in this level set, or the number of sample points in the longitudinal direction of elevation tiles associate with this leve set
the height in pixels of images associated with tiles in this level set, or the number of sample points in the latitudinal direction of elevation tiles associate with this level set
determines how many levels to skip from retrieving texture during tile pyramid subdivision
determines the lowest resolution level number. .
Throws
If any dimension is zero
Constructs a level set with parameters from a specified level set.
Parameters
source level set
Constructs a level set with parameters from a specified configuration. The configuration's sector must be non-null, its first level delta must be positive, its number of levels must be 1 or more, and its tile width and tile height must be 1 or greater.
Parameters
the configuration for this level set
