ImageGraphImpl

public ImageGraphImpl()

Method Detail

getId

public java.lang.String getId()

Description copied from interface: Element

Returns the id string of this element

Specified by:

getId in interface Element

Returns:

the id string

getMapping

public ImageMappingEx getMapping()

Description copied from interface: ImageGraph

Returns the mapping of this image.

Specified by:

getMapping in interface ImageGraph

Specified by:

getMapping in interface ImageGraphEx

Returns:

the mapping of this image

setMapping

public void setMapping(ImageMapping mapping)

Specified by:

setMapping in interface ImageGraph

getData

public SingleBandImageData getData()

Description copied from interface: Graph

Returns the graph data that this graph will draw.

Specified by:

getData in interface Graph

Specified by:

getData in interface ImageGraph

Returns:

setData

public void setData(SingleBandImageData data)

Specified by:

setData in interface ImageGraph

thisEffectiveColorChanged

public void thisEffectiveColorChanged()

Description copied from interface: ComponentEx

Called when setColor() or parentEffectiveColorChanged() change the effective color of this component.

Specified by:

thisEffectiveColorChanged in interface ComponentEx

mappingChanged

public void mappingChanged()

Description copied from interface: ImageGraphEx

Notify this graph that the mapping limits or LUT changed.

Specified by:

mappingChanged in interface ImageGraphEx

createCacheHolder

public java.lang.Object createCacheHolder()

Description copied from interface: IntermediateCacheEx

Create a cache holder to keep intermediate calculation result. This method is called by PlotEnvironment.commit(), before create thread-safe copy for renderers. The PlotEnvironment will keep hard reference to the returned Object. Usually the returned object is used as key of WeakHashMap.

Specified by:

createCacheHolder in interface IntermediateCacheEx

Returns:

an object to that PlotEnvironment should keep reference

copyStructure

public ComponentEx copyStructure(java.util.Map<ElementEx,ElementEx> orig2copyMap)

Description copied from interface: ElementEx

Create a structural copy of this element and put them into orig2copyMap. All properties are not copied. The parent of the copy are not set by this method.

Specified by:

copyStructure in interface ComponentEx

Specified by:

copyStructure in interface ElementEx

Overrides:

copyStructure in class ComponentImpl

Parameters:

orig2copyMap - original element to copy map

Returns:

the structural copy of this element

copyFrom

public void copyFrom(ElementEx src)

Description copied from interface: ElementEx

Copies all properties from given src to this element. Notice properties of sub-elements are not copied over.

Specified by:

copyFrom in interface ElementEx

Overrides:

copyFrom in class ComponentImpl

Parameters:

src - the src

draw

public void draw(java.awt.Graphics2D graphics)

Description copied from interface: ComponentEx

Draw this component only. All its children is not drawn.

Specified by:

draw in interface ComponentEx

Parameters:

graphics - to the Graphics2D drawing. The transformation of this component is not applied.
