## Styles
* `visibility`
* `fillAntialias`
* `fillOpacity`
* `fillColor`
* `fillOutlineColor`

* `fillPattern`
### `visibility`
Whether this layer is displayed.
- Type
-
enum
- Default Value
visible- Supported Values
-
-
visible: The layer is shown.
-
none: The layer is not shown.
### `fillAntialias`
Whether or not the fill should be antialiased.
- Type
-
boolean
- Default Value
true- Expression Parameters
zoom
### `fillOpacity`
The opacity of the entire fill layer. In contrast to the `fillColor`, this value will also affect the 1px stroke around the fill, if the stroke is used.
- Type
-
number
- Default Value
1- Minimum
0- Maximum
1- Expression Parameters
zoom, feature, feature-state
### `fillOpacityTransition`
The transition affecting any changes to this layer’s fillOpacity property.
- Type
-
{ duration, delay }
- Units
-
milliseconds
- Default Value
-
{duration: 300, delay: 0}
### `fillColor`
The color of the filled part of this layer. This color can be specified as `rgba` with an alpha component and the color's opacity will not affect the opacity of the 1px stroke, if it is used.
- Type
-
color
- Default Value
#000000- Disabled By
fillPattern- Expression Parameters
zoom, feature, feature-state
### `fillColorTransition`
The transition affecting any changes to this layer’s fillColor property.
- Type
-
{ duration, delay }
- Units
-
milliseconds
- Default Value
-
{duration: 300, delay: 0}
### `fillOutlineColor`
The outline color of the fill. Matches the value of `fillColor` if unspecified.
- Type
-
color
- Disabled By
fillPattern- Expression Parameters
zoom, feature, feature-state
### `fillOutlineColorTransition`
The transition affecting any changes to this layer’s fillOutlineColor property.
- Type
-
{ duration, delay }
- Units
-
milliseconds
- Default Value
-
{duration: 300, delay: 0}
### `fillTranslate`
The geometry's offset. Values are [x, y] where negatives indicate left and up, respectively.
- Type
-
array
- Default Value
[0,0]- Units
pixels- Expression Parameters
zoom
### `fillTranslateTransition`
The transition affecting any changes to this layer’s fillTranslate property.
- Type
-
{ duration, delay }
- Units
-
milliseconds
- Default Value
-
{duration: 300, delay: 0}
### `fillTranslateAnchor`
Controls the frame of reference for `fillTranslate`.
- Type
-
enum
- Default Value
map- Supported Values
-
-
map: The fill is translated relative to the map.
-
viewport: The fill is translated relative to the viewport.
- Requires
fillTranslate- Expression Parameters
zoom
### `fillPattern`
Name of image in sprite to use for drawing image fills. For seamless patterns, image width and height must be a factor of two (2, 4, 8, ..., 512). Note that zoomDependent expressions will be evaluated only at integer zoom levels.
- Type
-
resolvedImage
- Expression Parameters
zoom, feature
### `fillPatternTransition`
The transition affecting any changes to this layer’s fillPattern property.
- Type
-
{ duration, delay }
- Units
-
milliseconds
- Default Value
-
{duration: 300, delay: 0}
