canvas postscript options

I save the canvas image to a postscript file. I have tried different
options but inspection of the generated "EPS" file through gv or
display reveal that the canvas postscript options seem not to affect
the daved eps image at all. Here is my simple code:

$plot(canvas) postscript -file $filname \
-rotate $OrientFlag \
-width $print_box_width \
-height $print_box_height \
-pagewidth 400 \
-pageheight 500 \
-x 0.0 \
-y 0.0
# -pagewidth $print_box_width
# -pageheight $print_box_height
# -pageanchor s
#
where print_box_width = 900 = print_box_height.
The hope is to scale the generated eps image according to the
Ghostscript needs
(http://www.cs.wisc.edu/~ghost/doc/AFPL/6.50/Use.htm#Switches)
But the produced eps image does not get scaled at all no matter all my
attempts with changing the canvas postscript options.
The reason to do taht is that it's well known taht the EPS files
generated by Tcl/Tk are huge (postscript level 3). To workaround this
problem in environments where many EPS images have to be kept on disk
and disk space is being saturated, here they postprocess the Tk
generated EPS file through the Adobe Distiller accoding to the
following steps: eps -> pdf -> ps
But this transformation crops the original eps image that you can at

and the resulting PS image is trimmed and also the texts are messed up
as you can see at:

My question for whoever is amenable to help is three-folded ...
Are there canvas postscript options that can help solve this conversion
problem maybe generating an EPS image that is "compatible" with the
Abobe Distiller ?
How can I have Tk to generate a scaled image .... what are the golden
rules to do that ?
Is there any way to generate a PS level-1 (more compact) file from
saving the Tk canvas image ?

Thank you very much and Happy New Year,
Maura
