We all know that exists \externalfigure[...][...]
Now, suppose I'm able to make a buffer with raw data,
something like
\Raw{<89>PNG^M
^Z
^@^@^@^MIHDR^@^@^@
^@^@^@
^H^B^@^@^@^BPXê^@^@^@^AsRGB^@(R)Î^\é^@^@^@

...
(it's a black png 10x10 pixel, in attach.)
How can I use it with, let's say
\internalfigure[\Raw][...] ?
Of course, write it down to a temp file and then use
\externalfigure[temp][..],
but I would like to avoid this way .
you mean that the bytes should become an image?
yes, exactly so
...
well, you can try some pdf magic using inline image date in hex format
or so, but i never looked into that
a little suggestion .....?
