Constructor Detail

GrappaShape

public GrappaShape(int type,
                   double x,
                   double y,
                   double width,

                   boolean diagonalsArg,
                   java.lang.Object extra)

Constructs a new GrappaShape object. The winding rule for this path is defaulted (from Grappa.windingRule).

Parameters:

type - the shape specifier (.e.g., EGG_SHAPE).

x - the x-coordinate of the polygon center point.

y - the y-coordinate of the polygon center point.

width - the overall width of the polygon bounding box.

height - the overall height of the polygon bounding box.

sidesArg - the number of sides of the polygon.

peripheriesArg - the number of peripheries (outlines) of the polygon.

distortionArg - a distortion factor applied to the polygon shape, when non-zero

skewArg - a skewing factor applied to the polygon shape, when non-zero

orientationArg - an orientation angle in radians.

roundedArg - a directive to round the corners.

diagonalsArg - a directive to draw catercorners at the vertices.

extra - used only with the record shape at present, it provides a string of tuples giving interior partition information.
