Constructor Details

TLcdEarthArrowIcon

public TLcdEarthArrowIcon(ALcdEarth2DVectorIcon.Parameterization aType,
 TLcdColorMap aColorMap)

Constructs a new arrow icon.

Parameters:

aType - the parameterization type

aColorMap - the mapping from strength to color

Method Details

getColorMap

public TLcdColorMap getColorMap()

Returns the mapping from strengths to colors.

Returns:

the mapping from strength to color

setColorMap

public void setColorMap(TLcdColorMap aColorMap)

Sets the mapping from strengths to colors.

Parameters:

aColorMap - the mapping from strength to color

paintIcon

public void paintIcon(Graphics aGraphics,
 int aX,
 int aY,
 double[] aParameters)

Description copied from interface: ILcdParameterizedIcon

Paint the icon at the specified location for the parameters

Specified by:

paintIcon in interface ILcdParameterizedIcon

Parameters:

aGraphics - the Graphics on which the icon is painted

aX - the x coordinate at which the icon is painted. aX is the x-coordinate of the top left corner point of the icon.

aY - the y coordinate at which the icon is painted. aY is the y-coordinate of the top left corner point of the icon.

aParameters - the parameter values

getWidth

public int getWidth(double[] aParameters)

Description copied from interface: ILcdParameterizedIcon

Returns the width of the icon for the given parameter values.

Specified by:

getWidth in interface ILcdParameterizedIcon

Parameters:

aParameters - the parameter values as passed in ILcdParameterizedIcon.paintIcon(java.awt.Graphics, int, int, double[])

Returns:

the width

getHeight

public int getHeight(double[] aParameters)

Description copied from interface: ILcdParameterizedIcon

Returns the height of the icon for the given parameter values.

Specified by:

getHeight in interface ILcdParameterizedIcon

Parameters:

aParameters - the parameter values as passed in ILcdParameterizedIcon.paintIcon(java.awt.Graphics, int, int, double[])

Returns:

the height

anchorPointSFCT

public void anchorPointSFCT(double[] aParameters,
 Point aPointSFCT)

Description copied from class: ALcdEarthParameterizedIcon

Returns the anchor point of this icon. The anchor point of an icon is the point on the icon that is attached to the underlying object. For example: a circle icon is attached to an underlying point object by its center. An arrow icon can for example be attached to its object at the start of the arrow. The x-coordinate of the anchor point typically lies between 0 and getWidth(). The y-coordinate typically lies between 0 and getHeight().

Note that implementations don't need to take the anchor point into account when implementing the paintIcon method. The coordinates passed to that method always represent the top left corner of the icon. Callers of the paint method should make sure that the anchor point is taken into account.

A good default implementation can be to use the middle of the icon:

 aPointSFCT.setLocation(getWidth(aParameters) / 2, getHeight(aParameters) / 2);
 

This method implementation provides a default anchor point: (width/2, height/2). Override this method to provide an other anchor point.

Specified by:

anchorPointSFCT in interface ILcdParameterizedIcon

Overrides:

anchorPointSFCT in class ALcdEarthParameterizedIcon

Parameters:

aParameters - the parameter values

aPointSFCT - the point that has to be moved to the location of the anchor point of this icon.

getOrientation

public double getOrientation()

Returns 0. The orientation of the wind barbs is computed based on the wind values, when they are painted.

Specified by:

getOrientation in interface ILcdOriented

Returns:

0
