Class Mark

java.lang.Object
  org.deegree.graphics.sld.Mark

All Implemented Interfaces:

Marshallable

public class Mark
extends Object
implements Marshallable

A Mark takes a "shape" and applies coloring to it. The shape can be derived either from a well-known name (such as "square"), an external URL in various formats (such as, perhaps GIF), or from a glyph of a font. Multiple external formats may be used with the semantic that they all contain the equivalent shape in different formats. If an image format is used that has inherent coloring, the coloring is discarded and only the opacity channel (or equivalent) is used. A Halo, Fill, and/or Stroke is applied as appropriate for the shape's source format.

Method Detail

getWellKnownName

public String getWellKnownName()

Gives the well known name of a Mark's shape. Allowed values include at least "square", "circle", "triangle", "star", "cross", and "x", though map servers may draw a different symbol instead if they don't have a shape for all of these. Renderings of these marks may be made solid or hollow depending on Fill and Stroke parameters. The default value is "square".

Returns:

the WK-Name of the mark

setWellKnownName

public void setWellKnownName(String wellKnownName)

Sets the well known name of a Mark's shape. Allowed values include at least "square", "circle", "triangle", "star", "cross", and "x", though map servers may draw a different symbol instead if they don't have a shape for all of these. Renderings of these marks may be made solid or hollow depending on Fill and Stroke parameters. The default value is "square".

Parameters:

wellKnownName - the WK-Name of the mark

getFill

public Fill getFill()

A Fill allows area geometries to be filled. There are two types of fills: solid-color and repeated GraphicFill. In general, if a Fill element is omitted in its containing element, no fill will be rendered. The default is a solid 50%-gray (color "#808080") opaque fill.

Returns:

the fill of the mark

setFill

public void setFill(Fill fill)

sets the

Parameters:

fill - the fill of the mark

getStroke

public Stroke getStroke()

A Stroke allows a string of line segments (or any linear geometry) to be rendered. There are three basic types of strokes: solid Color, GraphicFill (stipple), and repeated GraphicStroke. A repeated graphic is plotted linearly and has its graphic symbol bended around the curves of the line string. The default is a solid black line (Color "#000000").

Returns:

the stroke of the mark

setStroke

public void setStroke(Stroke stroke)

sets

Parameters:

stroke - the stroke of the mark

getAsImage

public BufferedImage getAsImage(Feature feature,
                                int size)
                         throws FilterEvaluationException

Draws the given feature on the buffered image. The drawing values are used from the 'Fill' object (if set). or white as a default fill color and black as a stroke color. If the stroke is null the BasicStroke values (CAP_ROUND, JOIN_ROUND) will be used.

Be careful to set the buffered image first!.

Parameters:

feature -

size - DOCUMENT ME!

Returns:

The feature as a buffered image with a the 'Fill' values. or white as a default fill color and black as a stroke color.

Throws:

FilterEvaluationException

setAsImage

public void setAsImage(BufferedImage bufferedImage)

Sets the mark as an image. RThis method is not part of the sld specifications but it is added to speed up applications.

Parameters:

bufferedImage - the bufferedImage to be set for the mark
