                 boolean largeArcFlag,
                 boolean sweepFlag)

Constructor.

Parameters:

fromx - x coordinate of the origin point.

fromy - y coordinate of the origin point.

tox - x coordinate of the target point.

toy - y coordinate of the target point.

xradius - radius of the ellipse along its x axis.

yradius - radius of the ellipse along its y axis.

xrotation - rotation (in radians) of the ellipse's x axis.

largeArcFlag - true iff the path will sweep the long way around the ellipse.

sweepFlag - true iff the path will sweep clockwise around the ellipse.

Method Detail

equals
