                                        java.lang.Object data)

Description copied from class: Java2Dresource

Primary calculation of image dimensions - used when HTML code is generated to render IMG's width and height Subclasses should override this method to provide correct sizes of rendered images

Overrides:

getDimensions in class Java2Dresource

Returns:

dimensions of the image to be displayed on page

getDimensions

protected java.awt.Dimension getDimensions(org.ajax4jsf.resource.ResourceContext resourceContext)

Description copied from class: Java2Dresource

Secondary calculation is used basically by getImage method

Overrides:

getDimensions in class Java2Dresource

Returns:

getGradientHeight

protected int getGradientHeight()

Returns:

the gradientHeight

getBaseColor

protected java.lang.String getBaseColor()

Returns:

the baseColor

getGradientColor

protected java.lang.String getGradientColor()

Returns:

the gradientColor

isHorizontal

protected boolean isHorizontal()

Returns:

the horizontal

drawGradient

protected void drawGradient(java.awt.Graphics2D g2d,
                            java.awt.Shape shape,
                            GradientType.BiColor colors,
                            int height)

paint

protected void paint(org.ajax4jsf.resource.ResourceContext resourceContext,
                     java.awt.Graphics2D g2d)

Description copied from class: Java2Dresource

Template method for create image as Applet-like paint.

Overrides:

paint in class Java2Dresource

Parameters:

resourceContext - - current resource context.

g2d - - graphics to paint.

paintGradient

protected void paintGradient(java.awt.Graphics2D g2d,
                             BaseGradient.Data data)

Parameters:

g2d -

data -

restoreData

protected void restoreData(BaseGradient.Data data,
                           Zipper2 zipper2)

deserializeData

protected java.lang.Object deserializeData(byte[] objectArray)

Description copied from class: InternetResourceBase

Deserialize parameters object from byte array. By default, used Java de-serialisation from ObjectOutputStream , but implementations can override this method ( togewer with getDataToStore ) for implement short version.

Overrides:

deserializeData in class InternetResourceBase

Returns:

createData

protected BaseGradient.Data createData()

saveData

protected void saveData(javax.faces.context.FacesContext context,
                        BaseGradient.Data data,

Description copied from class: InternetResourceBase

Template method to construct resource-specific data ( to store in resource URI ). If resource must store any data in session or other cache, it must be done here. Since lightweight realisation, information for restore such data muct be returned by this method.

Overrides:

getDataToStore in class InternetResourceBase

Parameters:

context - - current faces context.

data - - data for build information, usually current UIComponent

Returns:

- any Serializable object, or null.
