#### new Cesium.MapGISFeatureLayer(imageryProvider, options)
MapGIS/Feature/MapGISFeatureLayer.js 150

`options` | Object | optional Object with the following properties:
Name | Type | Default | Description
--- | --- | --- | ---
`rectangle` | Rectangle | `imageryProvider.rectangle` | optional The rectangle of the layer. This rectangle can limit the visible portion of the imagery provider.
`alpha` | Number | function | `1.0` | optional The alpha blending value of this layer, from 0.0 to 1.0. This can either be a simple number or a function with the signature `function(frameState, layer, x, y, level)`. The function is passed the current frame state, this layer, and the x, y, and level coordinates of the imagery tile for which the alpha is required, and it is expected to return the alpha value to use for the tile.
`nightAlpha` | Number | function | `1.0` | optional The alpha blending value of this layer on the night side of the globe, from 0.0 to 1.0. This can either be a simple number or a function with the signature `function(frameState, layer, x, y, level)`. The function is passed the current frame state, this layer, and the x, y, and level coordinates of the imagery tile for which the alpha is required, and it is expected to return the alpha value to use for the tile. This only takes effect when `enableLighting` is `true`.
`dayAlpha` | Number | function | `1.0` | optional The alpha blending value of this layer on the day side of the globe, from 0.0 to 1.0.

This only takes effect when `enableLighting` is `true`.
`brightness` | Number | function | `1.0` | optional The brightness of this layer. 1.0 uses the unmodified imagery color. Less than 1.0 makes the imagery darker while greater than 1.0 makes it brighter. This can either be a simple number or a function with the signature `function(frameState, layer, x, y, level)`. The function is passed the current frame state, this layer, and the x, y, and level coordinates of the imagery tile for which the brightness is required, and it is expected to return the brightness value to use for the tile. The function is executed for every frame and for every tile, so it must be fast.

This can either be a simple number or a function with the signature `function(frameState, layer, x, y, level)`. The function is passed the current frame state, this layer, and the x, y, and level coordinates of the imagery tile for which the contrast is required, and it is expected to return the contrast value to use for the tile. The function is executed for every frame and for every tile, so it must be fast.
`hue` | Number | function | `0.0` | optional The hue of this layer. 0.0 uses the unmodified imagery color. This can either be a simple number or a function with the signature `function(frameState, layer, x, y, level)`.

The function is passed the current frame state, this layer, and the x, y, and level coordinates of the imagery tile for which the saturation is required, and it is expected to return the contrast value to use for the tile. The function is executed for every frame and for every tile, so it must be fast.
`gamma` | Number | function | `1.0` | optional The gamma correction to apply to this layer. 1.0 uses the unmodified imagery color. This can either be a simple number or a function with the signature `function(frameState, layer, x, y, level)`.

##### Throws:

- DeveloperError : This object was destroyed, i.e., destroy() was called.
