The projection determines the\n * coordinate system of the center, and its units determine the units of the\n * resolution (projection units per pixel). The default projection is\n * Web Mercator (EPSG:3857).\n *\n * ### The view states\n *\n * A View is determined by three states: `center`, `resolution`,\n * and `rotation`. Each state has a corresponding getter and setter, e.g.\n * `getCenter` and `setCenter` for the `center` state.\n *\n * The `zoom` state is actually not saved on the view: all computations\n * internally use the `resolution` state. Still, the `setZoom` and `getZoom`\n * methods are available, as well as `getResolutionForZoom` and\n * `getZoomForResolution` to switch from one system to the other.\n *\n * ### The constraints\n *\n * `setCenter`, `setResolution` and `setRotation` can be used to change the\n * states of the view, but any constraint defined in the constructor will\n * be applied along the way.\n *\n * A View object can have a *resolution constraint*, a *rotation constraint*\n * and a *center constraint*.\n *\n * The *resolution constraint* typically restricts min/max values and\n * snaps to specific resolutions. It is determined by the following\n * options: `resolutions`, `maxResolution`, `maxZoom` and `zoomFactor`.\n * If `resolutions` is set, the other three options are ignored. See\n * documentation for each option for more information. By default, the view\n * only has a min/max restriction and allow intermediary zoom levels when\n * pinch-zooming for example.\n *\n * The *rotation constraint* snaps to specific angles. It is determined\n * by the following options: `enableRotation` and `constrainRotation`.\n * By default rotation is allowed and its value is snapped to zero when approaching the\n * horizontal.\n *\n * The *center constraint* is determined by the `extent` option. By\n * default the view center is not constrained at all.\n *\n * ### Changing the view state\n *\n * It is important to note that `setZoom`, `setResolution`, `setCenter` and\n * `setRotation` are subject to the above mentioned constraints. As such, it\n * may sometimes not be possible to know in advance the resulting state of the\n * View. For example, calling `setResolution(10)` does not guarantee that\n * `getResolution()` will return `10`.\n *\n * A consequence of this is that, when applying a delta on the view state, one\n * should use `adjustCenter`, `adjustRotation`, `adjustZoom` and `adjustResolution`\n * rather than the corresponding setters. This will let view do its internal\n * computations. Besides, the `adjust*` methods also take an `anchor`\n * argument which allows specifying an origin for the transformation.\n *\n * ### Interacting with the view\n *\n * View constraints are usually only applied when the view is *at rest*, meaning that\n * no interaction or animation is ongoing. As such, if the user puts the view in a\n * state that is not equivalent to a constrained one (e.g. rotating the view when\n * the snap angle is 0), an animation will be triggered at the interaction end to\n * put back the view to a stable state;\n *\n * @api\n */\nclass View extends BaseObject {\n /**\n * @param {ViewOptions} [options] View options.\n */\n constructor(options) {\n super();\n\n /***\n * @type {ViewOnSignature}\n */\n this.on;\n\n /***\n * @type {ViewOnSignature}\n */\n this.once;\n\n /***\n * @type {ViewOnSignature}\n */\n this.un;\n\n options = Object.assign({}, options);\n\n /**\n * @private\n * @type {Array}\n */\n this.hints_ = [0, 0];\n\n /**\n * @private\n * @type {Array>}\n */\n this.animations_ = [];\n\n /**\n * @private\n * @type {number|undefined}\n */\n this.updateAnimationKey_;\n\n /**\n * @private\n * @const\n * @type {import(\"./proj/Projection.js\").default}\n */\n this.projection_ = createProjection(options.projection, 'EPSG:3857');\n\n /**\n * @private\n * @type {import(\"./size.js\").Size}\n */\n this.viewportSize_ = [100, 100];\n\n /**\n * @private\n * @type {import(\"./coordinate.js\").Coordinate|undefined}\n */\n this.targetCenter_ = null;\n\n /**\n * @private\n * @type {number|undefined}\n */\n this.targetResolution_;\n\n /**\n * @private\n * @type {number|undefined}\n */\n this.targetRotation_;\n\n /**\n * @private\n * @type {import(\"./coordinate.js\").Coordinate}\n */\n this.nextCenter_ = null;\n\n /**\n * @private\n * @type {number}\n */\n this.nextResolution_;\n\n /**\n * @private\n * @type {number}\n */\n this.nextRotation_;\n\n /**\n * @private\n * @type {import(\"./coordinate.js\").Coordinate|undefined}\n */\n this.cancelAnchor_ = undefined;\n\n if (options.projection) {\n disableCoordinateWarning();\n }\n if (options.center) {\n options.center = fromUserCoordinate(options.center, this.projection_);\n }\n if (options.extent) {\n options.extent = fromUserExtent(options.extent, this.projection_);\n }\n\n this.applyOptions_(options);\n }\n\n /**\n * Set up the view with the given options.\n * @param {ViewOptions} options View options.\n */\n applyOptions_(options) {\n const properties = Object.assign({}, options);\n for (const key in ViewProperty) {\n delete properties[key];\n }\n this.setProperties(properties, true);\n\n const resolutionConstraintInfo = createResolutionConstraint(options);\n\n /**\n * @private\n * @type {number}\n */\n this.maxResolution_ = resolutionConstraintInfo.maxResolution;\n\n /**\n * @private\n * @type {number}\n */\n this.minResolution_ = resolutionConstraintInfo.minResolution;\n\n /**\n * @private\n * @type {number}\n */\n this.zoomFactor_ = resolutionConstraintInfo.zoomFactor;\n\n /**\n * @private\n * @type {Array|undefined}\n */\n this.resolutions_ = options.resolutions;\n\n /**\n * @type {Array|undefined}\n * @private\n */\n this.padding_ = options.padding;\n\n /**\n * @private\n * @type {number}\n */\n this.minZoom_ = resolutionConstraintInfo.minZoom;\n\n const centerConstraint = createCenterConstraint(options);\n const resolutionConstraint = resolutionConstraintInfo.constraint;\n const rotationConstraint = createRotationConstraint(options);\n\n /**\n * @private\n * @type {Constraints}\n */\n this.constraints_ = {\n center: centerConstraint,\n resolution: resolutionConstraint,\n rotation: rotationConstraint,\n };\n\n this.setRotation(options.rotation !== undefined ? options.rotation : 0);\n this.setCenterInternal(\n options.center !== undefined ? options.center : null,\n );\n if (options.resolution !== undefined) {\n this.setResolution(options.resolution);\n } else if (options.zoom !== undefined) {\n this.setZoom(options.zoom);\n }\n }\n\n /**\n * Padding (in css pixels).\n * If the map viewport is partially covered with other content (overlays) along\n * its edges, this setting allows to shift the center of the viewport away from that\n * content.
