| 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 |
| charts[] | An array of chart items of type WebChart available on the footprint layer. |
| disablePopup | Indicates whether a client should ignore popups defined in this layer |
| effect | Effect provides various filter functions to achieve different visual effects similar to how image filters (photo apps) work. |
| enableEditing | Indicates whether a client should allow feature editing for this layer. Applicable only if the layer has editing capability. |
| featureEffect | Feature Effect emphasizes or deemphasizes features that satisfy a filter using graphical effects |
| formInfo | A formInfo object defining the content of the form when you are editing a feature. |
| 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. |
| 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 window when you click a feature on the map. |
| showLabels | Labels will display if this property is set to true and the layer also has a labelingInfo property associated with it. This property can get stored in the web map config and in the item/data. |
| showLegend | Boolean value indicating whether to display the layer in the legend. Default value is true. |

|---|---|
| drawingInfo.labelingInfo[] | An object defining the properties used for labeling the layer. If working with Map Image layers, this property is only applicable if the layer is enabled with dynamic layers |
| drawingInfo.renderer | An object defined which provides the symbology for the layer. If working with Map Image layers, this property is only applicable if the layer is enabled with dynamic layers |
| drawingInfo.scaleSymbols | Boolean property indicating whether symbols should stay the same size in screen units as you zoom in. A value of false means the symbols stay the same size in screen units regardless of the map scale. |
| 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. |
