;+ ; NAME: ; CLIPBOARD ; ; PURPOSE: ; ; The purpose of this program is to copy the contents of a ; graphics window to the clipboard for subsequent pasting into ; applications such as Photoshop or Powerpoint. ; ; AUTHOR: ; ; FANNING SOFTWARE CONSULTING ; David Fanning, Ph.D. ; 1645 Sheely Drive ; Fort Collins, CO 80526 USA ; Phone: 970-221-0438 ; E-mail: davidf@dfanning.com ; Coyote's Guide to IDL Programming: http://www.dfanning.com/ ; ; CATEGORY: ; ; 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. ; ; OUTPUTS: ; None. ; ; COMMON BLOCKS: ; None. ; ; DEPENDENCIES: ; ; Uses the IDLgrClipboard object introduced in IDL 5.2(?). ; ; PROCEDURE: ; ; 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. ; Added _EXTRA keyword to pass COLOR_QUAN keywords along. 28 Oct 2002.
