public class RenderingHintsRenderPolicy
extends StandardRenderPolicy

The RenderingHintsRenderPolicy is a StandardRenderPolicy that lets you set RenderingHints on the java.awt.Graphics object before the layer is painted, and then simply paints the current graphic list. No conditions or deviations are considered. This class can be set with properties.

The properties have to look like:

 
 
  prefix.renderingHints=RENDERINGHINTS_KEY1 RENDERINGHINTS_KEY2
  prefix.RENDERINGHINTS_KEY1=RENDERINGHINTS_VALUE1
  prefix.RENDERINGHINTS_KEY2=RENDERINGHINTS_VALUE2
 
 
 

For example, for a GraticuleLayer in the properties file with a 'graticule' prefix:

 
 
  graticule.renderPolicy=textAliasing
  graticule.textAliasing.class=com.bbn.openmap.layer.policy.RenderingHintsRenderPolicy
  graticule.textAliasing.renderingHints=KEY_TEXT_ANTIALIASING
  graticule.textAliasing.KEY_TEXT_ANTIALIASING=VALUE_TEXT_ANTIALIAS_ON
 
 
 

The HintsMapBeanRepaintPolicy uses a RenderingHintsRenderPolicy with properties that look like these, where 'repaintPolicy' is the prefix for the RenderingHintsRenderPolicy:

 
 
  repaintPolicy.class=com.bbn.openmap.HintsMapBeanRepaintPolicy
  repaintPolicy.renderingHints=KEY_ANTIALIASING
  repaintPolicy.KEY_ANTIALIASING=VALUE_ANTIALIAS_ON
  repaintPolicy.KEY_RENDERING=VALUE_RENDER_SPEED
 
 
 

See the java.awt.RenderingHints javadocs for the key-value pairs that can be used.

RenderingHintsRenderPolicy

public RenderingHintsRenderPolicy(OMGraphicHandlerLayer layer)

Method Detail

setRenderingHints

public void setRenderingHints(java.awt.RenderingHints rh)

Set the RenderingHints Map that should be used on the MapBean. If null, no modifications will be set on the MapBean's Graphics object.

getRenderingHints

public java.awt.RenderingHints getRenderingHints()

Get the RenderingHints Map that should be used on the MapBean. May be null (default).

put

public void put(java.lang.Object key,
                java.lang.Object value)

Set a RenderingHint on this object.

Parameters:

key - RenderingHint KEY

value - RenderingHint VALUE

paint

public void paint(java.awt.Graphics g)

If you are going to change the Graphics object in this method, you should make a copy of it first using the Graphics.create() method so the changes won't affect other layers.

Specified by:

paint in interface RenderPolicy

Overrides:

paint in class StandardRenderPolicy

setRenderingHints

public void setRenderingHints(java.awt.Graphics g)

setProperties

public void setProperties(java.lang.String prefix,
                          java.util.Properties props)

Description copied from class: OMComponent

Sets the properties for the OMComponent.

Specified by:

setProperties in interface PropertyConsumer

Overrides:

setProperties in class OMComponent

Parameters:

prefix - the token to prefix the property names

props - the Properties object

getProperties

public java.util.Properties getProperties(java.util.Properties props)

Description copied from class: OMComponent

PropertyConsumer method, to fill in a Properties object, reflecting the current values of the OMComponent. If the component has a propertyPrefix set, the property keys should have that prefix plus a separating '.' prepended to each property key it uses for configuration.

Specified by:

getProperties in interface PropertyConsumer

Overrides:

getProperties in class OMComponent

Parameters:

props - a Properties object to load the PropertyConsumer properties into. If props equals null, then a new Properties object should be created.

Returns:

Properties object containing PropertyConsumer property values. If getList was not null, this should equal getList. Otherwise, it should be the Properties object created by the PropertyConsumer.

getPropertyInfo

public java.util.Properties getPropertyInfo(java.util.Properties props)

Description copied from class: OMComponent

Method to fill in a Properties object with values reflecting the properties able to be set on this PropertyConsumer. The key for each property should be the raw property name (without a prefix) with a value that is a String that describes what the property key represents, along with any other information about the property that would be helpful (range, default value, etc.). For Layer, this method should at least return the 'prettyName' property.

Specified by:

getPropertyInfo in interface PropertyConsumer

Overrides:

getPropertyInfo in class OMComponent

Parameters:

props - a Properties object to load the PropertyConsumer properties into. If getList equals null, then a new Properties object should be created.

Returns:

Properties object containing PropertyConsumer property values. If getList was not null, this should equal getList. Otherwise, it should be the Properties object created by the PropertyConsumer.
