Constructor Detail

JFitsComponent

public JFitsComponent(JFitsCanvas fits)

Constructs a new fits component. The main initialization is done in the init method.

Method Detail

setComposedProperties

public void setComposedProperties(PropertySupplying prop)

Defaults the icon size. The super method resets the contrast and brightness values to the properties defaults.

Specified by:

setComposedProperties in interface PropertyAware

getComposedProperties

public PropertySupplying getComposedProperties()

Returns the properties of the panel and the properties of the fits canvas.

Specified by:

getComposedProperties in interface PropertyComposed

init

public void init()

Initializes the shape canvas. This includes some default setting that might be overruled in subclasses.

Specified by:

init in interface Initializable

getDisplayMap

public Map<String,Object> getDisplayMap()

getContrast

public double getContrast()

Returns the current contrast on the image in the range of -1 to +1.

setContrast

public boolean setContrast(double newcontrast)

Sets the contrast of the image. This method can destory data in a sense that this method is not totally reversable. E.g., if one sets a contrast of -1 (the minimum value allowd), all data will then have the median value. Setting a contrast of zero later will not restore the data, unless called in conjuncture with #revertFromFits.

getBrightness

public double getBrightness()

Returns the current brightness.

setBrightness

public boolean setBrightness(double newbright)

Sets the brightness of the image. This method can destory data in a sense that this method is not totally reversable. E.g., if one sets a brightness of -1 (the minimum value allowd), all data will then have zero value. Setting a brightness of zero later will not restore the data, unless called in conjuncture with #revertFromFits.

prepareToDisplay

public BufferedImage prepareToDisplay(BufferedImage src)

Rescales the image to display the new brightness and contrast.

Specified by:

prepareToDisplay in interface ImageOperation

stateChanged

public void stateChanged(ChangeEvent e)

Invoked when the contrast or brightness slider was moved. We call the brightness or contrast adjustment on the fits canvas only if the slider has come to rest.

Specified by:

stateChanged in interface ChangeListener

getCanvas

protected JFitsCanvas getCanvas()

Returns the fits canvas.

propertyChange

public void propertyChange(PropertyChangeEvent e)

Notified when the fits canvas has been reset. Adjustes the sliders.

Specified by:

propertyChange in interface PropertyChangeListener

getSaveBuffer

public BufferedImage getSaveBuffer()

Returns the buffered image from the fits canvas.

Specified by:

getSaveBuffer in interface Savable
