ConstructorOptions

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. Default value - 1.0

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. Default value - 1.0

Color to be used as alpha.

Threshold for color-to-alpha. Default value - 0.004

The contrast of this layer. 1.0 uses the unmodified imagery color. Less than 1.0 reduces the contrast while greater than 1.0 increases it. 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. Default value - 1.0

Cartographic rectangle for cutting out a portion of this ImageryLayer.

The alpha blending value of this layer on the day 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. Default value - 1.0

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). The function is passed the current frame state, this layer, and the x, y, and level coordinates of the imagery tile for which the gamma is required, and it is expected to return the gamma value to use for the tile. The function is executed for every frame and for every tile, so it must be fast. Default value - 1.0

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 hue 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. Default value - 0.0

The texture minification filter to apply to this layer. Possible values are TextureMagnificationFilter.LINEAR and TextureMagnificationFilter.NEAREST. Default value - TextureMagnificationFilter.LINEAR

The maximum anisotropy level to use for texture filtering. If this parameter is not specified, the maximum anisotropy supported by the WebGL stack will be used. Larger values make the imagery look better in horizon views. Default value - maximum supported

The maximum terrain level-of-detail at which to show this imagery layer, or undefined to show it at all levels. Level zero is the least-detailed level.

The texture minification filter to apply to this layer. Possible values are TextureMinificationFilter.LINEAR and TextureMinificationFilter.NEAREST. Default value - TextureMinificationFilter.LINEAR

The minimum terrain level-of-detail at which to show this imagery layer, or undefined to show it at all levels. Level zero is the least-detailed level.

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. Default value - 1.0

The rectangle of the layer. This rectangle can limit the visible portion of the imagery provider. Default value - imageryProvider.rectangle

The saturation of this layer. 1.0 uses the unmodified imagery color. Less than 1.0 reduces the saturation while greater than 1.0 increases it. 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. Default value - 1.0

True if the layer is shown; otherwise, false. Default value - true

The SplitDirection split to apply to this layer. Default value - SplitDirection.NONE
