LineLayer
Welcome to the mapmyindia-map-react-native-beta wiki!
| Prop | Type | Default | Required | Description |
|---|---|---|---|---|
| id | string |
none |
false |
A string that uniquely identifies the source in the style to which it is added. |
| sourceID | string |
MapboxGL.StyleSource.DefaultSourceID |
false |
The source from which to obtain the data to style. If the source has not yet been added to the current style, the behavior is undefined. |
| sourceLayerID | string |
none |
false |
Identifier of the layer within the source identified by the sourceID property from which the receiver obtains the data to style. |
| aboveLayerID | string |
none |
false |
Inserts a layer above aboveLayerID. |
| belowLayerID | string |
none |
false |
Inserts a layer below belowLayerID |
| layerIndex | number |
none |
false |
Inserts a layer at a specified index |
| filter | array |
none |
false |
Filter only the features in the source layer that satisfy a condition that you define |
| minZoomLevel | number |
none |
false |
The minimum zoom level at which the layer gets parsed and appears. |
| maxZoomLevel | number |
none |
false |
The maximum zoom level at which the layer gets parsed and appears. |
| style | union |
none |
false |

lineCap
The display of line endings.
enum
butt
butt - A cap with a squared-off end which is drawn to the exact endpoint of the line.
round - A cap with a rounded end which is drawn beyond the endpoint of the line at a radius of one-half of the line's width and centered on the endpoint of the line.
square - A cap with a squared-off end which is drawn beyond the endpoint of the line at a distance of one-half of the line's width.
Parameters: zoom
lineJoin
The display of lines when joining.
enum
miter
bevel - A join with a squared-off end which is drawn beyond the endpoint of the line at a distance of one-half of the line's width.
round - A join with a rounded end which is drawn beyond the endpoint of the line at a radius of one-half of the line's width and centered on the endpoint of the line.
miter - A join with a sharp, angled corner which is drawn with the outer sides beyond the endpoint of the path until they meet.
camera
Parameters: zoom, feature
lineMiterLimit
Used to automatically convert miter joins to bevel joins for sharp angles.
number
2
Parameters: zoom
lineRoundLimit
Used to automatically convert round joins to miter joins for shallow angles.
number
1.05
Parameters: zoom
visibility
Whether this layer is displayed.
enum
visible
visible - The layer is shown.
none - The layer is not shown.
lineOpacity
The opacity at which the line will be drawn.
number
1
0
1
Parameters: zoom, feature, feature-state
lineColor
The color with which the line will be drawn.
color
#000000
linePattern
Parameters: zoom, feature, feature-state
lineTranslate
The geometry's offset. Values are [x, y] where negatives indicate left and up, respectively.
array<number>
[0,0]
pixels
Parameters: zoom
lineTranslateAnchor
Controls the frame of reference for lineTranslate.
enum
map
map - The line is translated relative to the map.
viewport - The line is translated relative to the viewport.
lineTranslate
Parameters: zoom
lineWidth
Stroke thickness.
number
1
pixels
0
camera
Parameters: zoom, feature, feature-state
lineGapWidth
Draws a line casing outside of a line's actual path. Value indicates the width of the inner gap.
number
0
pixels
0
Parameters: zoom, feature, feature-state
lineOffset
The line's offset. For linear features, a positive value offsets the line to the right, relative to the direction of the line, and a negative value to the left. For polygon features, a positive value results in an inset, and a negative value results in an outset.
number
0
pixels
Parameters: zoom, feature, feature-state
lineBlur
Blur applied to the line, in pixels.
number
0
pixels
0
Parameters: zoom, feature, feature-state
lineDasharray
Specifies the lengths of the alternating dashes and gaps that form the dash pattern. The lengths are later scaled by the line width. To convert a dash length to pixels, multiply the length by the current line width. Note that GeoJSON sources with lineMetrics: true specified won't render dashed lines to the expected scale. Also note that zoomDependent expressions will be evaluated only at integer zoom levels.
array<number>
line widths
0
linePattern
Parameters: zoom
linePattern
Name of image in sprite to use for drawing image lines. For seamless patterns, image width must be a factor of two (2, 4, 8, ..., 512). Note that zoomDependent expressions will be evaluated only at integer zoom levels.
string
Parameters: zoom, feature
lineGradient
Defines a gradient with which to color a line feature. Can only be used with GeoJSON sources that specify "lineMetrics": true.
color
lineDasharray, linePattern
Parameters: line-progress
