OGC ServerClass TLcdWMSGXYViewFactory

java.lang.Object

com.luciad.wms.server.TLcdWMSGXYViewFactory

public class TLcdWMSGXYViewFactory
extends Object

Factory class defining the methods to create and configure a new TLcdGXYViewBufferedImage to generate a map inside the WMS Server.

Extensions can be made to customize the view creation and initialization process:

• the protected method createGXYViewInstance creates TLcdGXYViewBufferedImage instances, capable of handling transparency if required (boolean parameter). Override this method to return extensions of TLcdGXYViewBufferedImage (e.g., to add a fixed logo in the corner of the map).
• the public method createGXYView
creates and customizes a TLcdGXYViewBufferedImage according to the supplied parameters. Override this method to change the configuration of TLcdGXYViewBufferedImage instances (e.g., to set a custom ILcdGXYViewLabelPainter).

Constructor Detail

TLcdWMSGXYViewFactory

public TLcdWMSGXYViewFactory()

Constructs a new TLcdWMSGXYViewFactory.

Method Detail

createGXYViewInstance

protected TLcdGXYViewBufferedImage createGXYViewInstance(boolean aTransparent)

Creates a new TLcdGXYViewBufferedImage with the given transparency setting.

For TLcdGXYViewBufferedImage objects, the transparency setting needs to be determined at creation time.

Parameters:

aTransparent - Whether the image should be capable of using transparent colors.

Returns:

a new TLcdGXYViewBufferedImage with the given transparency setting.

createGXYView

public TLcdGXYViewBufferedImage createGXYView(boolean aTransparent,
                                              int aWidth,
                                              int aHeight,
                                              ILcdBounds aWorldBounds,
                                              ILcdXYWorldReference aXYWorldReference,
                                              Color aBackgroundColor,
                                              TLcdWMSRequestContext aRequestContext)

Creates a new TLcdGXYViewBufferedImage with the given settings.

The default implementation creates a new view through createGXYViewInstance(boolean) and adjusts the following settings of the view:

• the width and height are respectively set to aWidth and aHeight,
• the background color is set to aBackgroundColor,
• the world reference is set to aXYWorldReference,
• the visible world area is set according to aWorldBounds,
• a view label placer is set.

Parameters:

aTransparent - whether the image should be capable of using transparent colors.

aWidth - the width to be used for the view.

aHeight - the height to be used for the view.

aWorldBounds - the bounds to fit on, expressed in the supplied world reference.

aXYWorldReference - the world reference to be used for the view.

aBackgroundColor - the background color to be used for the view.

aRequestContext - a container for the original request and other related request parameters.

Returns:

a new TLcdGXYViewBufferedImage initialized with the given settings.

createGXYView

public TLcdGXYViewBufferedImage createGXYView(boolean aTransparent,
                                              int aWidth,
                                              int aHeight,
                                              ILcdBounds aWorldBounds,
                                              ILcdXYWorldReference aXYWorldReference,
                                              double aRotation,
                                              Color aBackgroundColor,
                                              TLcdWMSRequestContext aRequestContext)

Creates a new TLcdGXYViewBufferedImage with the given settings.

The default implementation creates a new view through createGXYViewInstance(boolean) and adjusts the following settings of the view:

• the width and height are respectively set to aWidth and aHeight,
• the background color is set to aBackgroundColor,
• the world reference is set to aXYWorldReference,
• the visible world area is set according to aWorldBounds,
• the view rotation is set according to aRotation,
• a view label placer is set.

Parameters:

aTransparent - whether the image should be capable of using transparent colors.

aWidth - the width to be used for the view.

aHeight - the height to be used for the view.

aWorldBounds - the bounds to fit on, expressed in the supplied world reference.

aXYWorldReference - the world reference to be used for the view.

aRotation - the rotation to be used for the view, expressed in degrees.

aBackgroundColor - the background color to be used for the view.

aRequestContext - a container for the original request and other related request parameters.

Returns:

a new TLcdGXYViewBufferedImage initialized with the given settings.
