  • public class FillMBLayer
extends MBLayer
    MBLayer wrapper for "Fill" layers.

    • Constructor Detail

      • FillMBLayer

        public FillMBLayer​(JSONObject json)

    • Method Detail

      • defaultSemanticType

        protected SemanticType defaultSemanticType()

      • getFillAntialias

        public Expression getFillAntialias()
        (Optional) Whether or not the fill should be antialiased.

        Defaults to true.

        Returns:
        Whether the fill should be antialiased.

      • getFillOpacity

        public Number getFillOpacity()
                      throws MBFormatException
        (Optional) The opacity of the entire fill layer. In contrast to the fill-color, this value will also affect the 1px stroke around the fill, if the stroke is used.

        Defaults to 1.

        Returns:
        The opacity of the layer.
        Throws:
        MBFormatException - JSON provided inconsistent with specification

      • getFillColor

        public Color getFillColor()
        (Optional). 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.

        Colors are written as JSON strings in a variety of permitted formats.

        Defaults to #000000. Disabled by fill-pattern.

        Returns:
        The fill color.

      • fillColor

        public Expression fillColor()
        Access fill-color as literal or function expression, defaults to black.
        Returns:
        The fill color.

      • getFillOutlineColor

        public Color getFillOutlineColor()
        (Optional). Requires fill-antialias = true. The outline color of the fill.

        Matches the value of fill-color if unspecified. Disabled by fill-pattern.

        Returns:
        The outline color of the fill.

      • fillOutlineColor

        public Expression fillOutlineColor()
        Access fill-outline-color as literal or function expression, defaults to black.
        Returns:
        The outline color of the fill.

      • getFillTranslate

        public int[] getFillTranslate()
        (Optional) The geometry's offset. Values are [x, y] where negatives indicate left and up, respectively. Units in pixels. Defaults to 0, 0.
        Returns:
        The geometry's offset

      • fillTranslate

        public Point fillTranslate()
        Access fill-translate as Point.
        Returns:
        The geometry's offset, in pixels.

      • fillTranslateDisplacement

        public Displacement fillTranslateDisplacement()
        Processes the filter-translate into a Displacement.

        This should handle both literals and function stops: 

         filter-translate: [0,0]
 filter-translate: { property: "building-height", "stops": [[0,[0,0]],[5,[1,2]]] }
 filter-translate: [ 0, { property: "building-height", "TYPE":"exponential","stops": [[0,0],[30, 5]] }
        Returns:
        The geometry displacement

      • fillPattern

        public Expression fillPattern()
        (Optional) Name of image in a sprite to use for drawing image fills. For seamless patterns, image width and height must be a factor of two (2, 4, 8, ..., 512).
        Returns:
        name of the sprite for the fill pattern, or null if not defined.

      • hasFillPattern

        public boolean hasFillPattern()
        Returns:
        True if the layer has a fill-pattern explicitly provided.

      • transformInternal

        public List<FeatureTypeStyle> transformInternal​(MBStyle styleContext)
        Transform MBFillLayer to GeoTools FeatureTypeStyle.

        Notes:

        • stroke-width is assumed to be 1 (not specified by MapBox style)
        Specified by:
        transformInternal in class MBLayer
        Parameters:
        styleContext - The MBStyle to which this layer belongs, used as a context for things like resolving sprite and glyph names to full urls.
        Returns:
        FeatureTypeStyle

      • getType

        public String getType()
        Rendering type of this layer.
        Specified by:
        getType in class MBLayer
        Returns:
        TYPE
