metafun not working

metafun not working

[piskala upendran]

hello Taco,

I did search the result of all the files. All the
files are ok. except the MP-mpgraph.mpy and
MP-mpgraph.1. 

The mpy shows only the 

%mpochecksum : 8298

rest are all blank.


Iam also finding the error in MP-mpgraph.1

I am attaching the file.

It means both mpy and MP-mpgraph.1 files are wrong.
what should i do next. how to find the mistake?

thanks

upendran

Try to run the command
	makempy MP-mpgraph.mpo
manually. it will probably complain about missing pstoedit
command (see Hans' reply to mojca for more details).

Looks like it. The last line in the mpy file
should have been:

   endgraphictextfig;

not --cycle.

Can you try this?

   > makempy --force --noclean MP-mpgraph.mpo

The last lines in the (now kept) mpy-MP-mpgraph.tmp should be

         --cycle;
   endfig;
   end

If not, your pstoedit is broken. If yes, your makempy script
is broken.

Good luck, Taco

It seem that last pstoedit for linux is  broken.

I make MP.tex with  my old-friend 
Context.2002--still_crazy_after_all_these_years--, and pstoedit 3.33 and 
no problems.

Hello,

I have problems with this graphic too. First I noticed that I don't have 
pstoedit installed on my computer. I downloaded version 3.40 from 
http://www.pstoedit.net/pstoedit. When I now run this MP code I get a 
Windows (xp) errormessage: Unhandled exception in pstoedit.exe 
(STDDRIVERS.DLL): 0xC0000005: Access Violation. But I get the graphic 
rendered.

Any suggestions?

hmm, try on ctan:

ctan/support/pstoedit/windows

It should be an older (3.31) but good version .

cited from the webpage:

New or changed in 3.32:
...
workaround to cope with a change introduced since ghostscript 7.04.
Some new operators were added to ghostscript's internal array of
operators without increasing the maximum size of the array. This led
to the problem, that pstoedit couldn't add further operators.
...

I tried it out before reading that paragraph and I can approve: unless
you have an ancient GS, it doesn't work at all. 3.40 at least does
something even though it crashes.

but i have no problems here with gs 8.51 (all 8 versions worked ok) and pstoedit 
3.33, so how recent is your gs?

Confirm : under linux MP.tex works with pstoedit 3.33 , gs 8.51 and even 
ESP Ghostscript 7.07;
pstoedit 3.40 does not works correctly with gs 8.51 and 7.07

(Sorry Mojca, I was confused by numbers -- too much hot today -- )

I believe that the version 3.33 works, but I can't find it anywhere.
Even 3.40 is difficult to download. Usually only some polite
"bandwidth exceeded" message appears. I don't know if the development
of the program is stil in progress, but they could switch to
sourceforge.

The version on CTAN is 3.31 - this is the one which doesn't work even
for simple conversions outside ConTeXt. The paragraph I posted to the
list was taken from "New or changed in 3.32". This means that version
3.31 can't cope with the old GS.

pstoedit 3.40 seems to work as well. I can make conversions from
postscript to metapost outside ConTeXt without any problem. Also the
posted example with metafun trickery works somehow. It crashes the
pstoedit program, but obviously pstoedit manages to produce the proper
output before crashing.

I sent a short email to the email mentioned on the webpage - I hope
they will answer.

seems so, this stand alone --cycle does not look good. See taco's previosu 
response.

MP.tex works after downgrading to pstoedit 3.33

I got the following answer from the author of pstoedit:

In [MikTeX]/scripts/context/perl/makempy.pl I removed -ssp [simulate 
subpaths] from the following two routines:

sub make_mp_pictures_ps
   { process ("metapost file") ;
     run ($tmpfile, "$pstoedit", "-ssp -dt -f mpost $posfile $tmpfile") }

sub make_mp_pictures_pdf
   { process ("metapost file") ;
     run ($tmpfile, "$pstoedit", "-ssp -dt -f mpost $pdffile $tmpfile") }

pstoedit now doesn't crash any more, but 'P' or 'O' for example don't 
have "holes" any more. I'll try to reinstall my cygwin or to compile the 
source of pstoedit on Linux later. If I understood correctly than this 
patch should solve the problem and -ssp should work again.

Besides that, pstoedit will move to sourceforge, so it will hopefully 
soon be possible to download it more easily than it is now :)

do you need a cygwin version on windows? there is a regular one
