Class FlashLabelSymbolizer

java.lang.Object
  nl.idgis.giserver.FlashSymbolizer
      nl.idgis.giserver.FlashLabelSymbolizer

public class FlashLabelSymbolizer
extends FlashSymbolizer

The FlashLabelSymbolizer defines the context for geometry owning label presention.
The context place holder for the flash character will be filled.There is one flashcharacter(FlashText) which will be constant for all TextSymbolizer based geometries for the concerning feature. The possible label attributes which must be taking into account when position a label will be registered if possible on initiation.
Label attributes with a variable nature will be generated each time the CreateMatrix method is invoked.

Constructor Detail

FlashLabelSymbolizer

public FlashLabelSymbolizer(org.deegree.graphics.sld.Symbolizer symbolizer,
                            org.deegree.model.feature.Feature feature,
                            FlashMap map)

Constructor. The place holder will be filled with the created flash character (FlashText).

Parameters:

symbolizer - dictating (sld) symbolizer

feature - concerning feature instance

map - concerning map

Method Detail

createMatrix

public nl.idgis.flash.FlashMatrix createMatrix(double world_x_pos,
                                               double world_y_pos,
                                               FlashMap map)

Create the matrix parameter for SWF place object method. The matrix is created for the given x,y position in world coordinates. Registered label displacements will be taking into account at FlashMatrix construction.

Parameters:

world_x_pos - given position x in world coordinates

world_y_pos - given position y in world coordinates

map - concerning map

Returns:

FlashMatrix instance.

createMatrix

public nl.idgis.flash.FlashMatrix createMatrix(org.deegree.model.spatialschema.Geometry geo,
                                               FlashMap map)

Create the matrix parmeter for SWF place object method. The matrix is created for the given geometry. A position is derived from this geometry. The derivation for gemeotry which isn't a position is done by taking the the centroid as the position. This derivation may lead to extra displacements of the label w.r.t to the calculated position. Registered label displacements and the displacements from derivation geometry will be taking into account at FlashMatrix construction.

Parameters:

geo - : geometry

map - : concerning map

Returns:

FlashMatrix : new instance.

getFlashCharacter

public nl.idgis.flash.FlashCharacter getFlashCharacter()

Getter FlashText character.

Overrides:

getFlashCharacter in class FlashSymbolizer

Returns:

flash character

getColorSpaceBase

public java.awt.Color getColorSpaceBase()

Description copied from class: FlashSymbolizer

Get the color which can be used as color space base in colorTransform calculations.

Overrides:

getColorSpaceBase in class FlashSymbolizer

Returns:

Color space base , null => no base possible
