Hi, i have a question.
The question is in the example.

function test123, data, x, y, $
overplot=overplot

;; actually, there is a very complicated precess
;; but now simple case

;; Question. When keyword set "overplot=1" How can i get the "i1" property
;; (rgb_table, min_value.. and so on)?.
;; Yes, i know the esay way that overplot=i1.
;; But is this possible get the property of latest graphic(in this example, "i1")?
;;

i = image(data, x, y, $
rgb_table=rgb_table, $
overplot=overplot, $
/axis, aspect_ratio=0)
return, i
end

pro test

data = findgen(300, 300)
x = findgen(300)
y = x

i1 = image(data, x, y, rgb_table=33)

data2 = dist(300)
i2 = test123(data2, x+400, y, /overplot

end

Thanks.
