Gernot,

Since PS does not have an ARGB filter, you need to write a program (Pascal?)
that reads ARGB and spits-out pure-and-simple hex.
This "0fe1....ff>" file can be converted to jpeg with the DCT filter and make
it ordinary text file with the SCSII85 filter in one go (e.g. by using
ghostscript 8.0).

The first step is really simple and can be done millions of ways.
From the header you need the dimensions, from the trunk you may extract
8-bit bytes for r and g and b for every pixel (forget alpha for the time
being). To convert them to hex characters, I would probably use a translation
table for speed.

At PS level there is a difference between storing the image in "currentfile"
and in a string. Until Level3 "currentfile" can be used only once. If you want
the same image twice, you have to have two of them...
However, there is no size restriction on this type of storage.

If you store the image in a string, you may use it as many times you wish, but
there is a size restriction (64 kB if I remember well).
Many compressed images (less than 1/10 of hex) but few hex images would fit.
