I should mention that my goal is to have a single .ps file which
contains my plot and any annotations. I've included the
'instructions' from the annotation.pro help file.
Thanks again,
John K.
Choose "Objects only" to save only the annotation objects. Use this
mode to combine the annotations with PostScript commands that have
already been output to obtain the highest resolution. To use this
procedure, take the following steps:
1) Open the PostScript device and create the plot over which you
wish your annotations to appear. Be sure that it has the same aspect
ratio as does you drawing window. For example, if you have a 640 x
512 drawing window, and you wish to make your PostScript drawing 4
inches wide, the PostScript height or YSIZE must be set to 4.0 * 512 /
640 = 3.2 inches, e.g. DEVICE, XSIZE=4, YSIZE=3.2, /INCHES.
2) Select the window system as your plot device, and re-execute the
commands that produced the background you wish to annotate.
3) Call ANNOTATE, make your annotations, and then use this option to
output the PostScript. The PostScript device is not closed upon.
completion, as it is with the other two PostScript output options.
