you just need bigger pockets.

It's highly likely that I'm misunderstanding the problem/question here,
(especially since I've been using IDL object graphics for a whole hour
now) but, wouldn't the following code work?
xsize=29.7
ysize=21.0
;landscape
;set up a half scale window
oWindow = OBJ_NEW('IDLgrWindow', dimensions=[xsize/2.0, ysize/2.0],units=2)
oView = OBJ_NEW('IDLgrView',color=[200,200,200],$
LOCATION=[xsize/8.0,ysize/8.0], $
DIMENSIONS=[xsize/4.0,ysize/4.0],$
UNITS=2)
OScene = OBJ_NEW('IDLgrScene')
oScene->Add, oView
oModel = OBJ_NEW('IDLgrModel')
oView->Add, oModel
oText = OBJ_NEW('IDLgrText','Hello World',ALIGNMENT=0.5)
;yes, I know....
oModel->Add, oText
OWindow->Draw, oScene
c=obj_new('IDLgrClipboard',dimensions=[xsize,ysize], units=2)
oview->getproperty,dimensions=old_dimensions, $
location=old_location, $
units=old_units
oView->setproperty, dimensions=[xsize/2.,ysize/2.], $
location=[xsize/4.,ysize/4.], $
units=2
c->draw,/post,/vector,file='test.ps',oScene
oview->setproperty,dimensions=old_dimensions, $
location=old_location, $
units=old_units
wait,1
OBJ_DESTROY, oWindow
OBJ_DESTROY, oScene
obj_destroy,c
;(I think IDL always produces EPS files, when you ask for
postscript, it embeds the graphics in an A4 bounded box.)
Chris.

You must be WAY younger than I am. I've had to get new
glasses (again) so I can read my pocket German dictionary. :-(
Cheers,
David
P.S. It was either glasses or a halogen lamp to throw
enough light on the subject. The oven mitts to handle
the lamp is what swung the decision towards the glasses.
My oldest said he wouldn't drink beer with me if I went
to the bier garten mit my oven mitts. :-)

I've done this to shoehorn figures into a form I want. However
I make a 1 page latex article, and use all the includegraphics tex commands
to resize, rotate, position, etc (and add captions if desired).
[then latex and dvips the latex file, which creates a nice postscript file,
which I've put into other latex files.]
Cheers,
bob
PS for instance, I've used this to shrink a 4ft by 3ft poster into
a nice letter sized postscript file (although I don't do this anymore)

Let us know. You are not the only one looking for a solution here.

Slim to none.
Actually, I have a new strategy now that I have actually spent a few
minutes looking at PostScript. Since I can create an EPS, I should be
able to embed this EPS in another postscript file rather than convert
the EPS to PS. So just create a an empty PostScript file, include the
EPS, and throw in some translate and rotate commands. It's an idea at
least.

Prayer I think might be your best bet. :-)
How much PostScript do you know? In addition to the things
ps2eps does, you will have to find and change the BoundingBox
and PageBoundingBox tags, as well as the PageOrientation tag.
For a minimum. Probably a lot of other stuff as well.
You might be able to fake most of it by creating a PostScript
and encapsulated Postscript file and looking at the output
in a text editor. Judicious cut and paste might work...after
a while.
Maybe it would be easier to mock up a Microsoft Word
document and insert the EPS file using Active X components.
Just a suggestion. :-)
Cheers,
David
P.S. This whole PostScript situation is getting to be
a real bother. You write code for your display (always
24-bit these days, Hello!) and you have to write it
differently for 8-bit displays. I spent the afternoon
re-working my color tools to handle this situation
more transparently (testing now), but it is *still*
a bother. Sigh...

Okay, I think I got confused again between EPS and PS. It's been a long
day. I just realized that by its very nature an EPS file wouldn't know
anything with regards to what it's being printed on. It needs to be
included into something else in order to be printed. Do I have this
right? If so, my original question doesn't really apply, does it?
