Class BackgroundMBLayer

Object

MBLayer

BackgroundMBLayer

public class BackgroundMBLayer
extends MBLayer

The background color or pattern of the map.

MBLayer wrapper around a JSONObject representation of a "background" type latyer. All methods act as accessors on provided JSON layer, no other state is maintained. This allows modifications to be made cleanly with out chance of side-effect.

• get methods: access the json directly
• query methods: provide logic / transforms to GeoTools classes as required.

Optional string. Name of image in sprite to use for drawing an image background. For seamless patterns, image width and height must be a factor of two (2, 4, 8, ..., 512).

Returns:

Name of image in sprite to use for drawing an image background, or null if not defined.
