<div>I would have to use the appropriate form of tracing, of course. I actually don't think there would be any space at the beginning of the page, but I would check to be sure.</div>
<div> </div>
<div>The following code works, but with MetaPost, you do get the whole box, so it doesn't really help. On the second page of the TeX file, I show how to shift the letters using infinite glue. With this technique, you can put anything you want anywhere on the page. Here, I use a \vbox of \vsize and an \hbox of \hsize, but more often I use boxes of zero height or width, respectively, i.e., \vbox to 0pt and \hbox to 0pt, respectively. \vss and \hss, respectively, must be used in these boxes, as in the example below. You don't need an EPS file,</div>
<div>you can just put letters, words, paragraphs, math mode material, etc., into the box, e.g., \hbox to 0pt{\hskip-1cm A\hss}.</div>

<div>%% ttemp.mp</div>

outputtemplate := "%j%3c.eps";</div>

<div>end;</div>

<div>I can't say for sure what the problem is without looking at the log file for your example, but this is an example that works (see below).</div>
<div>The 10 x 10pt rule shows that it works. The boxes containing the `a' and the `A' are taller than the letters themselves. I'd have to check to be sure</div>
<div>there's no other space in your example.</div>
<div> </div>
<div>If you want a letter to be right at the edge of the paper, you can use MetaPost to achieve this effect. If I have a moment, I can make an example.</div>
<div>At the exact edge wouldn't be useful for printing, but it would work in a dvi, ps or pdf viewer.</div>
