domain to pixel

[Bill Hibbard]

 Hi Curtis,

MouseBehavior.getScreenCoords() is essentially
the inverse of findRay() and should ddo what you
need. See visad/examples/Test35.java for an
example.

Good luck,
Bill

  Hi,

  What is the easiest method for obtaining the pixel coordinates of a
  particular point in some Data object's domain space? In the past, I
  have used MouseBehavior.findRay to go the other way (the "hard" way):
  convert from pixel coordinates to cursor coordinates, and from there
  to domain coordinates using ScalarMap ranges. But what about going
  from domain to pixel? I am mostly interested in doing so for 2D
  displays.

  Thanks,
  Curtis
