Class: ViewfinderCards

ViewfinderCards()

A ViewfinderCards collection is a group of ViewfinderCardModel models that provide a location and list of layers to make visible and/or allow the user to open content in an iframe or new tab. Renamed from ZoomPresets for clarity when zoom presets were deprecated in favor of more generalized viewfinder cards in 2.37.0.

parse(resp, options) → {Array.<ViewfinderCardModel>}

Parse the configured viewfinder cards or the GeoJSON response from the LEO Network. Extended from the ZoomPresets parse method when zoom presets were deprecated in favor of more generalized viewfinder cards in 2.37.0. Applies default ordinality, labels, and icons and synthesizes legacy top-level parameters into a map type button action.

resp Array.<object> | object The configured cards passed to parse may be one of: 1. custom cards directly from a map config: a list of objects with properties like `description`, `latitude`, `longitude`, `height`, `title`, and `image` 2. the configuration for the LEO Network collection: an object with a `url` and optionally `layerIds` property 3. a GeoJSON response from the LEO Network.
options object Options for parsing the response.
Properties
Name Type Attributes Description
mapModel MapModel <optional>
 The map model that this collection is associated with, used to get all layers.

Returns:
A list of ViewfinderCardModel instances representing the parsed viewfinder cards.
Type
