Ryan,

Here's a procedure that uses import (from ImageMagick) to capture
a top level base. It helps to know the title of the base widget
as well as the widget id - then it is entirely automatic.
Otherwise you'll need to select the window with the mouse. (does
anyone know how to get the title of a base widget in IDL?)

Note that the type of file that you are capturing to is
determined by the extension of the filename: .ps for postscript,
.pdf for pdf, .jpg for jpeg, and so on.

Hope this helps, Mike

pro import_tlb, widget_id, filename, title=title
;; Bring the widget to the front:
widget_control, widget_id, iconify=0

;; If we know the window title, then capture it directly, otherwise
;; use what the user selects:
if n_elements(title) eq 1 then begin
cmnd = 'import -screen -window "' + title + '" ' + filename
endif else begin
cmnd = 'import -screen ' + filename
endelse
spawn, cmnd, result
print, result
end
