Here is a full code segment. I guess it is not working because of some missing classes but this class contains all the code regarding the gereralpath and area problem.

Basic it is part of an genetic algorithm. int dna[] is een array of integer which are trabnslate into polar coordinates, which are the edges of a "polygon".

Is p1 created just before this code? If it's a GeneralPath that you're reusing you'll need to have called reset() on it.

Also, if you could extract a full code segment that reproduces this then I can definitely help you. I just need to be able to see all the details.

Hi all

I have a problem with using the Area object. I first fill a generalpath and then making a new Area object.

But when i try to get the cooridinat back from the area object i got the coordinates in a different order and with some more. Who can seay what im doing wrong?

with regards AANT

i use the code:

//Here i make the Area object

  p1.moveTo( (float)coor[minYindex].getX(), (float)coor[minYindex].getY());
  for(int i = 0; i < pp.length; i++)
   p1.lineTo( (float)pp[i].getX(), (float)pp[i].getY());
  p1.closePath();

  Area area = new Area( p1 );
  Vector hoekpunten = new Vector();

//in the following code i try to get the coordinates back out of the area object

  PathIterator iterator = area.getPathIterator(null);
  double[] coords = new double[6];
  while( !iterator.isDone() )
  {
   switch( iterator.currentSegment(coords) )
   {
    case PathIterator.SEG_MOVETO:
    case PathIterator.SEG_LINETO:
//    case PathIterator.SEG_CLOSE:
     hoekpunten.add( new xyzPoint(coords[0],coords[1]) );
System.out.println("in decode X,Y = coor: "+coords[0]+" , "+coords[1] );
     break;
   }
   iterator.next();
  }

//The println is only because of the debugging and that why i know that the coordinates are not the the proper order and not the same number
