Examples of java.awt.geom.PathIterator.currentSegment()

java.awt.geom.PathIterator.currentSegment()
Returns the coordinates and type of the current path segment in the iteration. The return value is the path-segment type: SEG_MOVETO, SEG_LINETO, SEG_QUADTO, SEG_CUBICTO, or SEG_CLOSE. A float array of length 6 must be passed in and can be used to store the coordinates of the point(s). Each point is stored as a pair of float x,y coordinates. SEG_MOVETO and SEG_LINETO types returns one point, SEG_QUADTO returns two points, SEG_CUBICTO returns 3 points and SEG_CLOSE does not return any points. @param coords an array that holds the data returned fromthis method @return the path-segment type of the current path segment. @see #SEG_MOVETO @see #SEG_LINETO @see #SEG_QUADTO @see #SEG_CUBICTO @see #SEG_CLOSE
