Interface Fill

All Superinterfaces:

Fill

public interface Fill
extends Fill

The Fill object encapsulates the graphical-symbolization parameters for areas of geometries.

There are two types of fill: solid-color and repeated graphic fill.

The details of this object are taken from the OGC Styled-Layer Descriptor Report (OGC 02-070) version 1.0.0.:

 <xsd:element name="Fill">
   <xsd:annotation>
     <xsd:documentation>
       A "Fill" specifies the pattern for filling an area geometry.
       The allowed CssParameters are: "fill" (color) and "fill-opacity".
     </xsd:documentation>
   </xsd:annotation>
   <xsd:complexType>
     <xsd:sequence>
       <xsd:element ref="sld:GraphicFill" minOccurs="0"/>
       <xsd:element ref="sld:CssParameter" minOccurs="0"
                    maxOccurs="unbounded"/>
     </xsd:sequence>
   </xsd:complexType>
 </xsd:element>
 

Renderers can use this information when displaying styled features, though it must be remembered that not all renderers will be able to fully represent strokes as set out by this interface. For example, opacity may not be supported.

Notes:

• The graphical parameters and their values are derived from SVG/CSS2 standards with names and semantics which are as close as possible.

Method Detail

getColor

Expression getColor()

This parameter gives the solid color that will be used for a Fill.
The color value is RGB-encoded using two hexidecimal digits per primary-color component, in the order Red, Green, Blue, prefixed with the hash (#) sign. The hexidecimal digits beetween A and F may be in either upper or lower case. For example, full red is encoded as "#ff0000" (with no quotation marks). The default color is defined to be 50% gray ("#808080"). Note: in CSS this parameter is just called Fill and not Color.

Specified by:

getColor in interface Fill

Returns:

The color of the Fill encoded as a hexidecimal RGB value.

setColor

void setColor(Expression color)

This parameter gives the solid color that will be used for a Fill.
The color value is RGB-encoded using two hexidecimal digits per primary-color component, in the order Red, Green, Blue, prefixed with the hash (#) sign. The hexidecimal digits beetween A and F may be in either upper or lower case. For example, full red is encoded as "#ff0000" (with no quotation marks).

Parameters:

color - solid color that will be used for a Fill

getBackgroundColor

Expression getBackgroundColor()

Deprecated. value is not used, please use getColor()

This parameter gives the solid color that will be used as a background for a Fill.
The color value is RGB-encoded using two hexidecimal digits per primary-color component, in the order Red, Green, Blue, prefixed with the hash (#) sign. The hexidecimal digits beetween A and F may be in either upper or lower case. For example, full red is encoded as "#ff0000" (with no quotation marks). The default color is defined to be transparent.

Returns:

The background color of the Fill encoded as a hexidecimal RGB value.

setBackgroundColor

void setBackgroundColor(Expression backgroundColor)

Deprecated. Please use setColor( Expression )

This parameter gives the solid color that will be used as a background for a Fill.
The color value is RGB-encoded using two hexidecimal digits per primary-color component, in the order Red, Green, Blue, prefixed with the hash (#) sign. The hexidecimal digits beetween A and F may be in either upper or lower case. For example, full red is encoded as "#ff0000" (with no quotation marks).

Parameters:

backgroundColor - solid color that will be used as a background

getOpacity

Expression getOpacity()

This specifies the level of translucency to use when rendering the fill.
The value is encoded as a floating-point value between 0.0 and 1.0 with 0.0 representing totally transparent and 1.0 representing totally opaque, with a linear scale of translucency for intermediate values.
For example, "0.65" would represent 65% opacity. The default value is 1.0 (opaque).

Specified by:

getOpacity in interface Fill

Returns:

The opacity of the fill, where 0.0 is completely transparent and 1.0 is completely opaque.

setOpacity

void setOpacity(Expression opacity)

This specifies the level of translucency to use when rendering the fill.
The value is encoded as a floating-point value between 0.0 and 1.0 with 0.0 representing totally transparent and 1.0 representing totally opaque, with a linear scale of translucency for intermediate values.
For example, "0.65" would represent 65% opacity.

getGraphicFill

Graphic getGraphicFill()

This parameter indicates that a stipple-fill repeated graphic will be used and specifies the fill graphic to use.

Specified by:

getGraphicFill in interface Fill

Returns:

The graphic to use as a stipple fill. If null then no stipple fill should be used.

setGraphicFill

void setGraphicFill(Graphic graphicFill)

This parameter indicates that a stipple-fill repeated graphic will be used and specifies the fill graphic to use.
