  Define range of position coordinates

  Posted by Terje Lundgren on October 4, 2007 at 9:41 am

  I want to create an expression that limits the position values of a layer to a defined range of coordinates.

  The range of both x and y should be 0-200.

  x = value[0] ;
  y = value[1] ;

  if (x > 0){
  [x, y];}
  else{ [0,y];}
  // Locks x as expected on the left

  if (x < 200){ [x, y];} else{ [200 , y ];} // When this line is added the layer is locked on the right, but the previous if-statement is ignored. Additional code for the y values is needed. Any help appreciated.

  One way:

  x = clamp(value[0],0,200);
  y = clamp(value[1],0,200);
  [x,y]
