Converting legacy amstex picture with \LPic to latex

Question

I am converting legacy amstex code to latex. I am stuck on vector pictures in the document.

In the "main" document, there is code like this:

\centerline{\input fig11.tex}

In the fig11.tex file, there is code, that looks like this:

%%AmSTeX
\LPic 11.8 5.0 fig11.psp 
{}{}{
\atxy 20 5 \BText{some description}
%%.....more similar \atxy commands...%%
}

and fig11.psp looks like this (with far more lines of the "same thing"):

81 LBegin
/p0 { 120 5 } def
/p1 { 140 5 } def
/p2 { 70 10 } def
LNarrow
p0 p1 2 LTextloc
p2 p3 3 LTextloc
p3 p4 4 LTextloc
p5 LDot
p6 LDot
p14 p9 LLine
p14 p10 LLine
p15 p11 LLine
p15 p12 LLine
p23 p24 LVector
p26 p25 LVector
LEnd

(It is not a legal postscript.)

Now I don't have a clue how to convert those to something LaTeX will like (it doesn't know the \LPic command, lpic.sty seems like something a bit different and I can't force it to work anyway)

edit:

oh god. It's probably this frankly bizzare thing:

...I am not sure at all what to do with it.

Answer 1

What seems to be enough at the moment:

1. first, copying the postscript special changes from lhead to all the almost-postscript .psp files
2. add first line to all the .psp files with just %!
3. Adding boundingbox to the ps files with psfixbb
4. converting the .psp files to .pdfs (since I want to use pdflatex in the first place and I don't need to edit the files anymore)
5. deleting the special changes from the lhead file, leaving the rest as-is. (with changing \special{psfile=#3} into \includegraphics{#3}), result is here
6. removing the .psp filenames and replacing them with .pdfs in the fig.tex files
