; Graphics.
;
; CALLING SEQUENCE:
;
; CLIPBOARD, window_index
;
; OPTIONAL INPUTS:
;
; window_index: The window index number of the graphics window to
; copy. If absent, the current graphics window is used
; by default.
;
; KEYWORDS:
;
; All COLOR_QUAN keywords are allowed. In particular, if you are
; taking snapshots of line plots with few colors in them, you may
; get better results by calling the program with the CUBE=6 keyword
; set. Otherwise, white colors can sometimes be a bit gray.
;

; None.
;
; COMMON BLOCKS:
; None.
;
; DEPENDENCIES:

; Copies the window contents to a clipboard object.
;
; EXAMPLE:
;
; IDL> Window
; IDL> Plot, Findgen(11)
; IDL> CLIPBOARD
;
; RESTRICTIONS:
;
; May not work for all applications. Applications tested successfully
; include: Framemaker, Powerpoint, Photoshop, Excel, Microsoft Word.
; Converts 24-bit images to 2D images with color tables.
;
; MODIFICATION HISTORY:
;
; Written by: David W. Fanning, 24 October 2001.
