A Graphic is a "graphic symbol" with an inherent shape, color(s), and possibly size. A "graphic" can be very informally defined as "a little picture" and can be of either a raster or vector-graphic source type. The term "graphic" is used since the term "symbol" is similar to "Symbolizer" which is used in a different context in SE.

Since:

GeoAPI 2.2

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`Object`	`accept(StyleVisitor visitor, Object extraData)`	Calls the visit method of a StyleVisitor
`AnchorPoint`	`getAnchorPoint()`	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.
`Displacement`	`getDisplacement()`	The Displacement gives the X and Y displacements from the "hot-spot" point.
`Expression`	`getOpacity()`	Indicates the level of translucency as a floating point number whose value is between 0.0 and 1.0 (inclusive).
`Expression`	`getRotation()`	Returns the expression that will be used to calculate the rotation of the graphic when it is drawn.
`Expression`	`getSize()`	The Size element gives the absolute size of the graphic in uoms encoded as a floating- point number.
`List<GraphicalSymbol>`	`graphicalSymbols()`	Returns the list of external image files or marks that comprise this graphic.

- Method Detail
  - graphicalSymbols
```
@XmlElement("ExternalGraphic,Mark")
List<GraphicalSymbol> graphicalSymbols()
```
    Returns the list of external image files or marks that comprise this graphic. All elements of the list must be instances of either Mark or ExternalGraphic.
    
    Returns:
    
    List of Marks or ExternalGraphics; if empty it is to be treated a single default Mark.
  - getOpacity
```
@XmlParameter("stroke-opacity")
Expression getOpacity()
```
    Indicates the level of translucency as a floating point number whose value is between 0.0 and 1.0 (inclusive). A value of zero means completely transparent. A value of 1.0 means completely opaque. If null, the default value is 1.0, totally opaque.
    
    Returns:
    
    expression
  - getSize
```
@XmlParameter("Size")
Expression getSize()
```
    The Size element gives the absolute size of the graphic in uoms encoded as a floating- point number. The default size for an object is context-dependent. Negative values are not allowed. The default size of an image format (such as GIF) is the inherent size of the image. The default size of a format without an inherent size (such as SVG which are not specially marked) is defined to be 16 pixels in height and the corresponding aspect in width. If a size is specified, the height of the graphic will be scaled to that size and the corresponding aspect will be used for the width. An expected common use case will be for image graphics to be on the order of 200 pixels in linear size and to be scaled to lower sizes. On systems that can resample these graphic images "smoothly," the results will be visually pleasing.
    
    Returns:
    
    Expression
  - getRotation
```
@XmlParameter("Rotation")
Expression getRotation()
```
    Returns the expression that will be used to calculate the rotation of the graphic when it is drawn.
    The Rotation element gives the rotation of a graphic in the clockwise direction about its center point in decimal degrees, encoded as a floating-point number. Negative values mean counter-clockwise rotation. The default value is 0.0 (no rotation). Note that there is no connection between source geometry types and rotations; the point used for plotting has no inherent direction. Also, the point within the graphic about which it is rotated is format dependent. If a format does not include an inherent rotation point, then the point of rotation should be the centroid.
    
    Returns:
    
    Expression
  - getAnchorPoint
```
@XmlParameter("AnchorPoint")
AnchorPoint getAnchorPoint()
```
    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.
    
    Returns:
    
    AnchorPoint , if null should use a default point X=0.5 Y=0.5
  - getDisplacement
```
@XmlParameter("Displacement")
Displacement getDisplacement()
```
    The Displacement gives the X and Y displacements from the "hot-spot" point. This element may be used to avoid over-plotting of multiple graphic symbols used as part of the same point symbol. The displacements are in units of measure above and to the right of the point. The default displacement is X=0, Y=0.
    If Displacement is used in conjunction with Size and/or Rotation then the graphic symbol shall be scaled and/or rotated before it is displaced.s
    
    Returns:
    
    Displacement
  - accept
```
@Extension
Object accept(StyleVisitor visitor,
              Object extraData)
```
    Calls the visit method of a StyleVisitor
    Please note StlyeVisitor has methods to directly visit a Graphic, GraphicLegend, or GraphicFill or GraphicStroke; please call the most appropriate method.
    
    Parameters:
    
    visitor - the style visitor
