Parameters
Properties
Title
This parameter specifies the title to be displayed when the output feature is clicked or hovered over.
Description
This parameter specifies the description to be displayed when the output feature is clicked or hovered over.
Marker Style (for point geometries)
Marker Size
This parameter specifies the size of the selected marker symbol. If “small” is selected, a 12x12 pixel marker is displayed. “Medium” represents 18x18 pixels, and “large” represents 24x24 pixel markers.
Marker Symbol

This example shows a marker that has had its size, color, and symbol set by the MapboxStyler.
Stroke Style (for area boundaries and line geometries)
Stroke Color
This parameter specifies the pen color of the feature used to render the feature in the set color. The pen color determines the color of lines, and area boundaries. To edit this parameter, click the browse button to the right of the text field.
Stroke Opacity
Stroke opacity specifies the opacity of the pen color of the feature. A value of 1.0 is fully opaque, and 0.0 is completely transparent.
Stroke Width
Line Width specifies the width of line geometries and boundaries of area geometries.
Fill Style (for area geometries)
Polygon Fill Color
This parameter specifies the fill color for an area geometry on a feature used to render the interior feature in the set color. To edit this parameter, click the browse button to the right of the text field.
Fill Opacity
Fill Opacity specifies the opacity of the fill color for an area geometry on a feature. A value of 1.0 is fully opaque, and 0.0 is completely transparent.
