The /PRINT keyword can be used in order to make a hardcopy of the
output window, creating an output postscript file named
isocont.ps in the current IDL directory. If the hardcopy must be
inserted in a camera ready publication, it may be useful to use
/NONORTH and /NOCOPYRIGHT keywords (see section 3.3).
(See Fig. 17). With this option the postscript file
will be small and the text font will be of high quality.
Another possibility is to use the PS_COLOR routine of CIA, which captures the output of a given IDL window. It can create both postscript (though larger in size than the one created with the /PRINT option) and GIF files as output.
