Field Detail

serialVersionUID
final static long serialVersionUID(Code)
	Serialized version UID.

Constructor Detail

ImageViewer
public ImageViewer()(Code)
	Default constructor. Must be here, used during de-externalization

ImageViewer
public ImageViewer(ImageDataObject obj)(Code)
	Create a new image viewer. Parameters: obj - the data object holding the image

Method Detail

createClonedObject
protected CloneableTopComponent createClonedObject()(Code)
	Creates cloned object which uses the same underlying data object.

customZoom
public void customZoom(int fx, int fy)(Code)
	Perform zoom with specific proportion. Parameters: fx - numerator for scaled Parameters: fy - denominator for scaled

getHelpCtx
public HelpCtx getHelpCtx()(Code)
	Gets HelpContext.

getIcon
public Image getIcon()(Code)
	Overrides superclass method. Gets `Icon`.

getPersistenceType
public int getPersistenceType()(Code)
	Overriden to explicitely set persistence type of ImageViewer to PERSISTENCE_ONLY_OPENED

getSystemActions
public SystemAction[] getSystemActions()(Code)
	Overrides superclass method. Gets actions for this top component.

open
public void open(Workspace workspace)(Code)
	Docks the table into the workspace if top component is valid. (Top component may become invalid after deserialization)

preferredID
protected String preferredID()(Code)

readExternal
public void readExternal(ObjectInput in) throws IOException, ClassNotFoundException(Code)
	Deserialize this top component. Reads its data object and initializes itself in addition to common superclass behaviour. Parameters: in - the stream to deserialize from

reloadIcon
protected void reloadIcon()(Code)
	Reloads icon.

updateView
void updateView(ImageDataObject imageObj)(Code)

writeExternal
public void writeExternal(ObjectOutput out) throws IOException(Code)
	Serialize this top component. Serializes its data object in addition to common superclass behaviour. Parameters: out - the stream to serialize to

zoomIn
public void zoomIn()(Code)
	Draws zoom in scaled image.

zoomOut
public void zoomOut()(Code)
	Draws zoom out scaled image.
