[texhax] \epsfbox

[David Carlisle]

This is something very retro about this whole exchange, the usage is
so 1980's...:-) but anyway

the \vtop are doing nothing different to \vbox as in each case there
is only one nested box, and the vbox around epsbox is doing nothing at
all as that's already a box.

the hbox aligns its contents horizontally with their reference points
at the same level, the reference point of the first vtop is the
baseline of its first box which is baseline of hello, and the
reference point of the second vtop is the baseline of its first box,
which is that of the epsfbox, which is the bottom edge of the image.

you could use

\input epsf

\hbox{\vtop{\hsize5cm\noindent hallo}%
      \vtop{\null\epsfbox{fis1.ps}}}%

\bye

which puts the baseline of hello at the baseline of the null, above
the image, or use \lower to lower it a bit if that is too high.
