| Graphic | | public class Graphic implements Marshallable(Code) | | A Graphic is a "graphic symbol" with an inherent shape, color, and size. Graphics can either be
referenced from an external URL in a common format (such as GIF or SVG) or may be derived from a
Mark. Multiple external URLs may be referenced with the semantic that they all provide the same
graphic in different formats. The "hot spot" to use for rendering at a point or the start and
finish handle points to use for rendering a graphic along a line must either be inherent in the
external format or are system- dependent. 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 is 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. The
default if neither an ExternalURL nor a Mark is specified is to use the default Mark with a size
of 6 pixels. The size is in pixels and the rotation is in degrees clockwise, with 0 (default)
meaning no rotation. In the case that a Graphic is derived from a font-glyph Mark, the Size
specified here will be used for the final rendering. Allowed CssParameters are "opacity", "size",
and "rotation".

| Graphic | | protected Graphic(Object[] marksAndExtGraphics, ParameterValueType opacity, ParameterValueType size, ParameterValueType rotation)(Code) | | Creates a new Graphic instance.
Parameters:
marksAndExtGraphics - the image will be based upon these
Parameters:
opacity - opacity that the resulting image will have
Parameters:
size - image height will be scaled to this value, respecting the proportions
Parameters:
rotation - image will be rotated clockwise for positive values, negative values result inanti-clockwise rotation |
| Graphic | | protected Graphic(ParameterValueType opacity, ParameterValueType size, ParameterValueType rotation)(Code) | | Creates a new Graphic instance based on the default Mark: a square.
Parameters:
opacity - opacity that the resulting image will have
Parameters:
size - image height will be scaled to this value, respecting the proportions
Parameters:
rotation - image will be rotated clockwise for positive values, negative values result inanti-clockwise rotation |
| Graphic | | protected Graphic()(Code) | | Creates a new Graphic instance based on the default Mark: a square.

| addMarksAndExtGraphic | | public void addMarksAndExtGraphic(Object object)(Code) | | Adds an Object to an object-array that enables the access to the stored
ExternalGraphic and Mark -instances.
Parameters:
object - to be used as basis for the resulting image |
| exportAsXML | | public String exportAsXML()(Code) | | exports the content of the Graphic as XML formated String
xml representation of the Graphic |
| getAsImage | | public BufferedImage getAsImage(Feature feature) throws FilterEvaluationException(Code) | | Returns a BufferedImage representing this object. The image respects the
'Opacity', 'Size' and 'Rotation' parameters. If the 'Size'-parameter is omitted, the height
of the first ExternalGraphic is used. If there is none, the default value of 6
pixels is used.
the BufferedImage ready to be painted
throws:
FilterEvaluationException - if the evaluation fails |
| getMarksAndExtGraphics | | public Object[] getMarksAndExtGraphics()(Code) | | Returns an object-array that enables the access to the stored ExternalGraphic and
Mark -instances.
contains ExternalGraphic and Mark -objects |
| getOpacity | | public ParameterValueType getOpacity()(Code) | | returns the ParameterValueType representation of opacity
the ParameterValueType representation of opacity |
| getOpacity | | public double getOpacity(Feature feature) throws FilterEvaluationException(Code) | | The Opacity element gives the opacity to use for rendering the graphic.
Parameters:
feature - specifies the Feature to be used for evaluation of the underlying'sld:ParameterValueType' the (evaluated) value of the parameter
throws:
FilterEvaluationException - if the evaluation fails or the value is invalid |
| getRotation | | public ParameterValueType getRotation()(Code) | | returns the ParameterValueType representation of rotation
the ParameterValueType representation of rotation |
| getRotation | | public double getRotation(Feature feature) throws FilterEvaluationException(Code) | | The Rotation element gives the rotation of a graphic in the clockwise direction about its
center point in radian, encoded as a floating- point number. Negative values mean
counter-clockwise rotation. The default value is 0.0 (no rotation).
Parameters:
feature - specifies the Feature to be used for evaluation of the underlying'sld:ParameterValueType' the (evaluated) value of the parameter
throws:
FilterEvaluationException - if the evaluation fails or the value is invalid |
| getSize | | public ParameterValueType getSize()(Code) | | returns the ParameterValueType representation of size
the ParameterValueType representation of size |
| getSize | | public double getSize(Feature feature) throws FilterEvaluationException(Code) | | The Size element gives the absolute size of the graphic in pixels encoded as a floating-point
number. This element is also used in other contexts than graphic size and pixel units are
still used even for font size. The default size for an object is context-dependent. Negative
values are not allowed.
Parameters:
feature - specifies the Feature to be used for evaluation of the underlying'sld:ParameterValueType' the (evaluated) value of the parameter
throws:
FilterEvaluationException - if the evaluation fails or the value is invalid |
| removeMarksAndExtGraphic | | public void removeMarksAndExtGraphic(Object object)(Code) | | Removes an Object from an object-array that enables the access to the stored
ExternalGraphic and Mark -instances.
Parameters:
object - to be used as basis for the resulting image |
| setAsImage | | public void setAsImage(BufferedImage bufferedImage)(Code) | | Sets a BufferedImage representing this object. The image respects the 'Opacity',
'Size' and 'Rotation' parameters.
Parameters:
bufferedImage - BufferedImage to be set |
| setMarksAndExtGraphics | | public void setMarksAndExtGraphics(Object[] object)(Code) | | Sets the ExternalGraphic/ Mark-instances that the image
will be based on.
Parameters:
object - to be used as basis for the resulting image |
| setOpacity | | public void setOpacity(double opacity)(Code) | | The Opacity element gives the opacity of to use for rendering the graphic.
Parameters:
opacity - Opacity to be set for the graphic |
