Moving the bounding box around

We shall look at details of how to manipulate an embedded EPS figure.

Here is the complete TEX file eq.tex producing the label: 

\nopagenumbers
\parindent=0pt
\parskip=0pt

$$ \hbox{Area} = \int_{0}^{1} f(x) \, dx $$

\bye
Here is the page produced by it, with the bounding box of the label indicated:

Here is a closeup of the label in its bounding box:

Here are the first few lines of the EPS file eq.eps produced by dvips: 

%!PS-Adobe-2.0 EPSF-2.0
%%Creator: dvipsk 5.66a Copyright 1986-97 Radical Eye Software (www.radicaleye.com)
%%Title: eq.dvi
%%BoundingBox: 264 683 349 710

Here is the figure we want to insert the label in:

Its bounding box has lower left corner (0, 0). Here is the final figure:

Here is the part of the final file setting up coordinates: 

54 40 translate
-264 -683 translate

You can also see the entire file, in its development stage:

Here are some lines to make the label more interesting: 

108 40 translate
90 rotate
1.25 1.25 scale
-264 -683 translate

and here is the new label placement:
