Name Type Description
options

Options.

Name Type Description
features ol.Collection.<ol.Feature> | undefined

Only features contained in this collection will be able to be translated. If not specified, all features on the map will be able to be translated.
layers undefined | Array.<ol.layer.Layer> | function

A list of layers from which features should be translated. Alternatively, a filter function can be provided. The function will be called for each layer in the map and should return true for layers that you want to be translatable. If the option is absent, all visible layers will be considered translatable.
hitTolerance number | undefined

Hit-detection tolerance. Pixels inside the radius around the given position will be checked for features. This only works for the canvas renderer and not for WebGL. Default is 0.
