Constructor Detail

JSkyCanvas

public JSkyCanvas(ResourceSupplying prop)

Calls the superconstructor with no arguments.

Parameters:

ra - Right ascension of the center of projection, degrees.

de - Declination of the center of projection, degrees.

width - Field-of-view width in degrees.

height - Field-of-view height in degrees.

Method Detail

setComposedProperties

public void setComposedProperties(ResourceSupplying prop)

Sets the composed properties of this component. Defaults the preferred size, the centerdraw toggle, the field-of-view and the B&W drawing.

Specified by:

setComposedProperties in interface ResourceAware

Overrides:

setComposedProperties in class JFitsCanvas

init

public void init()

Adds the grid and constellation drawing info.

Specified by:

init in interface Initializable

Overrides:

init in class JFitsCanvas

addMark

private void addMark()

Adds the central mark.

toggleUseCatalogColor

public Action toggleUseCatalogColor()

Toggles black&white drawing.

toggleCenterDraw

public Action toggleCenterDraw()

Toggles black&white drawing.

setSection

public void setSection(double ra,
                       double de,

                       double ys)

Sets a new center of the sky chart. Catalogs are not updated, but all entries are deleted.

Parameters:

ra - Right ascension of center, degrees.

de - Declination of center, degrees.

xs - Field width in degrees.

ys - Field height in degrees.

addCatalog

Adds a catalog. Additionally, the shapes list is prepared to allow fast painting of the component. The star list had to be added prior to a call to this method.

Parameters:

cat - The catalog to add

usebv - If true, the catalog is split into different colors using the b-v of the stars.

removeCatalog

public boolean removeCatalog(String name)

Removes a catalog by name. Each shapes catalog that has a starting value like the catalog name is removed.

Returns:

True if the catalog was present.

removeFrom

private boolean removeFrom(String name,
                           Map<String,?> catalogs)

Removes a catalog by name. Each shapes catalog that has a starting value like the catalog name is removed.

Returns:

True if the catalog was present.

isEmpty

public boolean isEmpty()

Returns true if all drawable objects have no entries.

Overrides:

isEmpty in class JNormalizedCanvas

drawShapes

protected void drawShapes(Graphics2D g2d,
                          AffineTransform af)

We draw ourselfes by also showing the catalogs.
