Class figPac.fEllipticalArc 

java.lang.Object
   |
   +----figPac.fEllipticalArc
public class fEllipticalArc
extends Object
implements fElement, fInteractive, MouseListener, MouseMotionListener, ItemListener
This class draws an elliptical arc. WARNING: fEllipticalArc works only for horizontal x axes and vertical y axes. Otherwise you should use fCurve with the curve pEllipse.

Variable Index

o a
o ARC
o b
o CHORD
o defaultFillColor
The default color used to fill the curve on the screen.
o defaultPsFillColor
The default PostScript command used to color in the curve in PostScript when the fEnv variable useColorPs is "true".
o defaultPsFillGray
Controls the default density used to fill the curve in postscript.
o endAngle
o fillColor
The color used to fill the curve on the screen.
o FILLED
o psFillColor
The PostScript command used to color in the curve in PostScript when the fEnv variable useColorPs is "true".
o psFillGray
Controls the density used to fill the curve in postscript.
o startAngle
o type
The type determines whether the arc itself is plotted, whether and how it is closed and whether or not it is filled.
o WEDGE
o x
o y

Constructor Index

o fEllipticalArc()
o fEllipticalArc(double, double, double, double, double, double)
Creates an elliptical arc whose center is given by the first two arguments, whose semiaxes are given by the third and fourth arguments and whose initial and final angles are given by the final arguments.
o fEllipticalArc(double, double, double, double, double, double, long)
Creates an elliptical arc whose center is given by the first two arguments, whose semiaxes are given by the third and fourth arguments and whose initial and final angles are given by the fifth and sixth arguments and whose type is given by the last argument.

Variables

o x 
 public double x
o y 
 public double y
o a 
 public double a
o b 
 public double b
o startAngle 
 public double startAngle
o endAngle 
 public double endAngle
o ARC 
 public static long ARC
o FILLED 
 public static long FILLED
o CHORD 
 public static long CHORD
o WEDGE 
 public static long WEDGE
o type 
 public long type
The type determines whether the arc itself is plotted, whether and how it is closed and whether or not it is filled. To determine the value of type, start with type=0. If you wish to plot the arc add fEllipticalArc.ARC. If you wish to close it to form a chord or wedge add fEllipticalArc.CHORD or fEllipticalArc.WEDGE, respectively. If you wish to fill the arc add fEllipticalArc.FILLED. NOTE: at the present time this is fully implemented only in postscript. For screen rendering, the only options that work are ARC and FILLED, with the latter producing a filled wedge.

o defaultFillColor 
 public Color defaultFillColor
The default color used to fill the curve on the screen.

o fillColor 
 public Color fillColor
The color used to fill the curve on the screen.

o defaultPsFillGray 
 public double defaultPsFillGray
Controls the default density used to fill the curve in postscript. Black=0, white=1.

o psFillGray 
 public double psFillGray
Controls the density used to fill the curve in postscript. Black=0, white=1.

o defaultPsFillColor 
 public String defaultPsFillColor
The default PostScript command used to color in the curve in PostScript when the fEnv variable useColorPs is "true".

o psFillColor 
 public String psFillColor
The PostScript command used to color in the curve in PostScript when the fEnv variable useColorPs is "true".
