Class SLDs

java.lang.Object
  SLD
      net.refractions.udig.ui.graphics.SLDs

public class SLDs
extends SLD

Utility class for working with Geotools SLD objects.

This class assumes a subset of the SLD specification:

• Single Rule - matching Filter.INCLUDE
• Symbolizer lookup by name

When you start to branch out to SLD information that contains multiple rules you will need to modify this class.

Since:

0.7.0

Method Detail

textFont

public static FontData[] textFont(TextSymbolizer symbolizer)

Grabs the font from the first TextSymbolizer.

If you are using something fun like symbols you will need to do your own thing.

Parameters:

symbolizer - Text symbolizer information.

Returns:

FontData[] of the font's fill, or null if unavailable.

font

public static Font font(TextSymbolizer symbolizer)

getDefaultStyle

public static Style getDefaultStyle(StyledLayerDescriptor sld)

isSemanticTypeMatch

public static boolean isSemanticTypeMatch(FeatureTypeStyle fts,
                                          java.lang.String regex)

minScale

public static double minScale(FeatureTypeStyle fts)

Returns the min scale of the default rule, or 0 if none is set

maxScale

public static double maxScale(FeatureTypeStyle fts)

Returns the max scale of the default rule, or Double.NaN if none is set

getFeatureTypeStyle

public static FeatureTypeStyle getFeatureTypeStyle(Style s)

gets the first FeatureTypeStyle

getRasterSymbolizerRule

public static Rule getRasterSymbolizerRule(Style s)

Find the first rule which contains a rastersymbolizer, and return it

Parameters:

s - A style to search in

Returns:

a rule, or null if no raster symbolizers are found.

getPlacement

public static PointPlacement getPlacement(double horizAlign,
                                          double vertAlign,
                                          double rotation)
