Method Detail

setDisplacement

public void setDisplacement(Displacement offset)

Specified by:

setDisplacement in interface Graphic

setExternalGraphics

public void setExternalGraphics(ExternalGraphic... externalGraphics)

addExternalGraphic

public void addExternalGraphic(ExternalGraphic externalGraphic)

setMarks

public void setMarks(Mark... marks)

addMark

public void addMark(Mark mark)

setGap

public void setGap(Expression gap)

Specified by:

setGap in interface Graphic

setInitialGap

public void setInitialGap(Expression initialGap)

Specified by:

setInitialGap in interface Graphic

setSymbols

public void setSymbols(Symbol... symbols)

addSymbol

public void addSymbol(Symbol symbol)

setOpacity

public void setOpacity(Expression opacity)

Description copied from interface: Graphic

Graphic opacity.

Specified by:

setOpacity in interface Graphic

Parameters:

opacity - New value of property opacity.

setSize

public void setSize(Expression size)

Description copied from interface: Graphic

Indicates the size at which the graphic should be displayed.

If this value is null the natural size of the graphic will be used; or for graphics without a natural size like SVG files 16x16 will be used.

Specified by:

setSize in interface Graphic

setRotation

public void setRotation(Expression rotation)

Description copied from interface: Graphic

This parameter defines the rotation of a graphic in the clockwise direction about its centre point in decimal degrees. The value encoded as a floating point number.

Specified by:

setRotation in interface Graphic

Parameters:

rotation - in decimal degrees

setAnchorPoint

public void setAnchorPoint(AnchorPoint anchor)

Specified by:

setAnchorPoint in interface Graphic

accept

public Object accept(TraversingStyleVisitor visitor,
                     Object data)

Description copied from interface: Graphic

Calls the visit method of a StyleVisitor

Specified by:

accept in interface Graphic

Parameters:

visitor - the style visitor

accept

public void accept(StyleVisitor visitor)

Description copied from interface: Graphic

accepts a StyleVisitor - used by xmlencoder and other packages which need to walk the style tree

Specified by:

accept in interface Graphic

Parameters:

visitor - - the visitor object

graphicalSymbols

public List<GraphicalSymbol> graphicalSymbols()

Description copied from interface: Graphic

The items in this list are either a Mark or a ExternalGraphic.

This list may be directly edited; the items are considered in order from most preferred (say an SVG file) to least preferred (a simple shape) with the intension that the system will make use of the first entry which it is capabile of displaying.

Specified by:

graphicalSymbols in interface Graphic

getAnchorPoint

public AnchorPoint getAnchorPoint()

Description copied from interface: Graphic

The AnchorPoint element of a PointSymbolizer gives the location inside of a Graphic (or label - see 11.4.4) to use for anchoring the graphic to the main-geometry point. The coordinates are given as two floating-point numbers in the AnchorPointX and AnchorPointY elements each with values between 0.0 and 1.0 inclusive. The bounding box of the graphic/label to be rendered is considered to be in a coordinate space from 0.0 (lower-left corner) to 1.0 (upper-right corner), and the anchor position is specified as a point in this space. The default point is X=0.5, Y=0.5, which is at the middle height and middle length of the graphic/label text. A system may choose different anchor points to de-conflict graphics/labels.

Specified by:

getAnchorPoint in interface Graphic

Returns:

AnchorPoint , if null should use a default point X=0.5 Y=0.5

getGap

public Expression getGap()

Specified by:

getGap in interface Graphic

getInitialGap

public Expression getInitialGap()

Specified by:

getInitialGap in interface Graphic
