Save eps ghostscript error

Hi,

I'm using matplotlib 0.98.5.2 on Ubuntu with Ghostscript 8.70. The following code produces the following error. Can anyone verify whether this a problem with my installation or with matplotlib?

You code works okay with the current svn.

See if changing the distiller option makes any difference
("ps.usedistiller" in the rc file).

The best would be for you to upgrade to the recent release of
matplotlib if possible.

Thanks for looking at this. I upgraded to 99.1.1 (although the tar file was named 99.1.2) and I got the same error message. When I played with the ps.usedistiller option I found it only doesn't work when I set ps.usedistiller to xpdf. With False or ghostscript it works ok but gives me output with different page sizes. AFAIK xpdf is the way to go for publication quality graphics. Do you know how I can get it to work? Is it worth trying the svn version?

Thanks,
John.

My guess is that somehow the output format of bbox device in the
recent ghostscript has changed.

What kind of output do you get when you run

gs -dBATCH -dNOPAUSE -sDEVICE=bbox test.eps

in your shell (replace "test.eps" with any eps file you have)

I get

GPL Ghostscript 8.61 (2007-11-21)
Copyright (C) 2007 Artifex Software, Inc. All rights reserved.
This software comes with NO WARRANTY: see the file PUBLIC for details.
%%BoundingBox: 71 214 541 578
%%HiResBoundingBox: 71.207998 214.811993 540.629984 577.169982

The last two lines are what matplotlib requires to work.

Meanwhile, can you test if following changes make things work?

In lib/matplotlib/backends/backend_ps.py, comment out following two
lines near the end of the function "xpdf_distill" (around line 1458 in
my code), i.e.,

if eps:
pstoeps(tmpfile, bbox)

It will not raise the error, but may give you a wrong bbox.

Regards,

Thanks for looking at this. I upgraded to 99.1.1 (although the tar file
was named 99.1.2) and I got the same error message. When I played with
the ps.usedistiller option I found it only doesn't work when I set
ps.usedistiller to xpdf. With False or ghostscript it works ok but gives
me output with different page sizes. AFAIK xpdf is the way to go for
publication quality graphics. Do you know how I can get it to work? Is
it worth trying the svn version?

Thanks,
John.

You code works okay with the current svn.

See if changing the distiller option makes any difference
("ps.usedistiller" in the rc file).

The best would be for you to upgrade to the recent release of
matplotlib if possible.

What kind of output do you get when you run

The last two lines are what matplotlib requires to work.

which looks pretty similar to me

They were at line 1363. Now it works but with the wrong bbox as you predicted.

Thanks for help so far. Any more ideas? I'll try the svn if it is just a case of checking it out and compiling.

John.

_Jae-Joon_Lee1 · January 12, 2010, 12:25am

Please try.
I don't think the current svn version will make any difference. But,
at least I can send you a patch that I think fix the problem so that
you can test it.
I'll post the patch here soon.

Thanks again for quick response. I've got the svn version and applied the patch. Now I get this error (with ps.usedistiller : xpdf):

I'm afraid that there is not much I can help anymore.

Just in case, does the same error occur when my patch is not applied?

Is it an error or just a warning? If it is an error, can you post a
full traceback? I just want to know what step causes that.

Also, are you using the usetex mode? See if turning that on and off
make any difference.

Please specify the options you're using, e.g., distiller, usetex,
