SLDStyleFactory

public SLDStyleFactory()

Method Detail

getRenderingHints

public RenderingHints getRenderingHints()

The factory builds a fair number of buffered images to deal with external graphics that need resizing and the like. This hints will be used in those drawing operations.

setRenderingHints

public void setRenderingHints(RenderingHints renderingHints)

isLineOptimizationEnabled

public boolean isLineOptimizationEnabled()

Enabled by default, this optimization speeds up line rendering when the line width is less than 1.5 pixels when antialiasing is disblaed. Unfortunately it also prevents fine line width control when antialiasing is enabled. Given that the optimization has been hard coded for more than six years, we give the user control on this one since turning this off will change the rendering of all existing styles using thin line widths.

setLineOptimizationEnabled

public void setLineOptimizationEnabled(boolean lineOptimizationEnabled)

isVectorRenderingEnabled

public boolean isVectorRenderingEnabled()

Indicates whether vector rendering should be preferred when painting graphic fills (e.g., using a Mark as stipple) or vector Graphic objects such as SVG ExternalGraphics. The default behavior is to be disabled, meaning that graphic fills are painted as raster images using Java TexturePaint, and SVGs are rendered to a BufferedImage prior to painting on the target Graphics. This common behavior is faster and more suitable for on-screen rendering. Enabling this flag is recommended for rendering to off-screen Graphics such as when printing, cases in which the full quality of the original data should normally be preserved.

setVectorRenderingEnabled

public void setVectorRenderingEnabled(boolean vectorRenderingEnabled)

Sets whether vector rendering should be preferred when painting graphic fills (see isVectorRenderingEnabled() for more details).

Parameters:

vectorRenderingEnabled - a boolean value indicating whether vector rendering should be enabled or not.

getHitRatio

public double getHitRatio()

getHits

public long getHits()

getRequests

public long getRequests()

createStyle

public Style2D createStyle(Object drawMe,
                           Symbolizer symbolizer)

Creates a rendered style

Makes use of a symbolizer cache based on identity to avoid recomputing over and over the same style object and to reduce memory usage. The same Style2D object will be returned by subsequent calls using the same feature independent symbolizer with the same scaleRange.

Parameters:

drawMe - The feature

symbolizer - The SLD symbolizer

Returns:

A rendered style equivalent to the symbolizer

createStyle

public Style2D createStyle(Object drawMe,
                           Symbolizer symbolizer,
                           Range scaleRange)

Creates a rendered style

Makes use of a symbolizer cache based on identity to avoid recomputing over and over the same style object and to reduce memory usage. The same Style2D object will be returned by subsequent calls using the same feature independent symbolizer with the same scaleRange.

Parameters:

drawMe - The feature

symbolizer - The SLD symbolizer

scaleRange - The scale range in which the feature should be painted according to the symbolizer

Returns:

A rendered style equivalent to the symbolizer

createDynamicStyle

public Style2D createDynamicStyle(SimpleFeature f,
                                  Symbolizer symbolizer,
                                  Range scaleRange)

Creates a rendered style

Parameters:

f - The feature

symbolizer - The SLD symbolizer

scaleRange - The scale range in which the feature should be painted according to the symbolizer

Returns:

A rendered style equivalent to the symbolizer

Throws:

UnsupportedOperationException - if an unknown symbolizer is passed to this method

evaluateDashArray

public static float[] evaluateDashArray(Stroke stroke,
                                        Object feature)
                                 throws NumberFormatException

Throws:

NumberFormatException

getPaint

protected Paint getPaint(Fill fill,
                         Object feature,
                         Symbolizer symbolizer)

getComposite

protected Composite getComposite(Fill fill,
                                 Object feature)

Computes the Composite equivalent to the opacity in the SLD Fill

Parameters:

fill -

feature -

lookUpJoin

public static int lookUpJoin(String joinType)

DOCUMENT ME!

Parameters:

joinType - DOCUMENT ME!

Returns:

DOCUMENT ME!

lookUpCap

public static int lookUpCap(String capType)

DOCUMENT ME!

Parameters:

capType - DOCUMENT ME!

Returns:

DOCUMENT ME!

getComposite

public static Composite getComposite(Map<String,String> options)
