Annotation layers can be created by referencing a layer from a feature service. Annotation layers honor any feature templates configured in the source document.

Properties
| Property | Details |
|---|---|
| blendMode | Blend modes are used to create various effects by blending colors of top and background layers. normal blend mode is the default.Valid values: average, color, color-burn, color-dodge, darken, destination-atop, destination-in, destination-out, destination-over, difference, exclusion, hard-light, hue, invert, lighten, lighter, luminosity, minus, multiply, normal, overlay, plus, reflect, saturation, screen, soft-light, source-atop, source-in, source-out, vivid-light, xor |
| customParameters | A sequence of custom parameters appended to the URL of all requests related to a layer. |
| disablePopup | Indicates whether to allow a client to ignore popups defined by the service item. |
| effect | Effect provides various filter functions to achieve different visual effects similar to how image filters (photo apps) work. |
| enableEditing | Indicates whether a client can add, remove or update features in the layer. |
| id | A unique identifying string for the layer. |
| layerDefinition | A layerDefinition object defining the attribute schema and drawing information for the layer. See layerDefinition properties table. |
| layerType | String indicating the layer type. Valid value of this property ArcGISAnnotationLayer |
| opacity | The degree of transparency applied to the layer on the client side, where 0 is full transparency and 1 is no transparency. |
| popupInfo | A popupInfo object defining the content of popup windows when you click or query a feature. |
| refreshInterval | Refresh interval of the layer in minutes. Non-zero value indicates automatic layer refresh at the specified interval. Value of 0 indicates auto refresh is not enabled. |
| timeAnimation | Indicates whether to disable time animation if the layer supports it. |
| title | A user-friendly string title for the layer that can be used in a table of contents. |
| url | The URL to the layer. If the layer is not from a web service but rather a feature collection, then the url property is omitted. |
| visibility | Boolean property determining whether the layer is initially visible in the web map. |
| visibleLayers[] | An array of sublayer ids that should appear visible. These ids refer to subsets of the Annotation features in the AnnotationLayer, identified by their AnnotationClassId. |
layerDefinition properties
| Property | Details |
|---|---|
| barrierWeight | Optional weight of features in AnnotationLayers and DimensionLayers when considered as barriers to labeling. If not set but required, the default value is assumed to be High. Valid values:
|
| definitionExpression | SQL-based definition expression string that narrows the data to be displayed in the layer. |
| floorInfo | Contains floor-awareness information for the layer. |
| maxScale | Integer property used to determine the maximum scale at which the layer is displayed. |
| minScale | Integer property used to determine the minimum scale at which the layer is displayed. |
