What follows is the beginning of a postscript program to produce a certain drawing. I'd like to reduce the size to about 2" by 3", proportionally, but I know nothing about postscript programming. Could someone suggest what I might do? Thanks. If you need the whole file, let me know and I'll email it.

Thanks. >%!PS-Adobe-2.0 EPSF-1.2 >%%BoundingBox:5 40 715 530 If you want to continue knowing nothing about postscript programming (a good idea IMHO...) then you should just use one of the many programs that know how to handle EPS files. If you intend to put the drawing on a page of text, Wordperfect 5.1 would be a good choice. If you want to edit, warp, or otherwise distort the drawing or put text in circles around it, or lots of other fun stuff, CorelDraw would be a good choice, though you might still want to just save the modified output as another EPS file and let Wordperfect print it along with some normal text. If you want something free, a set of programs called "psutils" was recently posted to alt sources. It included a program called epsfit that will scale an EPS file to an arbitrary bounding box. I don't think it knows about EPS files that include the bitmap for viewing. Les Mikesell les@chinet.chi.il.us

The best way to scale to the size you want is to look at the bounding box
values of your graphic:
%%BoundingBox:5 40 715 530
These represent the lower left and upper right coordinates of your graphic.
This defines a rectange that is 710 x 490 points (where a point is 1/72").
You'll want to scale this down to a rectangle of 216 x 144 points (3" x 2").
Stick the following code at the top of the file:
/MyScale { 216 710 div 144 490 div scale } bind def
This will scale non-uniformly but ensures that the graphic is exactly
2" x 3".
If you want to scale uniformly in the X direction:
/MyScale { 216 710 div dup scale } bind def
If you want to scale uniformly in the Y direction:
/MyScale { 144 490 div dup scale } bind def
You'll probably also want to translate the picture around on the page:
X Y translate % Position on the page
MyScale % Scale to desired size
-5 -40 translate % Translate pic to lower left corner
Where X and Y are expressed in 1/72 of an inch. If you want the resulting
picture to be 1 inch from the left hand edge of the page and 2 inches
from the bottom, then X = 72 and Y = 144.
Hope this helps,
