hey,guys,I found the solution , very simple. first, a very important information of image is rgba channel and uv coordinate or xy coordinate, anyway, it like a line-ramp.
code in here:
Code

function get_sample(x, y)
   -- Image generation code goes here.
   ofx = get_sample_grayscale(x, y, OFFSETX)
   ofy = get_sample_grayscale(x, y, OFFSETY)

   adjx = get_sample_grayscale(x,y,ADJUSTX)
   adjy = get_sample_grayscale(x,y,ADJUSTY)

   dis = get_sample_grayscale(x,y,DISAPPEAR)

   pre = get_sample_grayscale(x, y, PERCENTAGE)
   r,g,b,a = get_sample_map(x+ofx*pre/dis-adjx,y+ofy*pre/dis-adjy,SOURCE)

   return r,g,b,a

end;

and I upload that to web site, but nothing reaction now..
