[Bug 1348384] Re: evince and okular do not render eps files correctly resulting in a black background

[Jeremy Bicha]

** Description changed:

  Impact
  ==
  This Ubuntu 14.04 SRU caused a regression where some .eps files have a black 
background that makes it almost impossible to see the original content.
  
  https://launchpad.net/ubuntu/+source/libspectre/0.2.7-2ubuntu1.1
  
  This was fixed in Ubuntu 15.04 and newer releases but was not fixed in
  14.04 until now.
  
  Test Case
  =
  Use Ubuntu's default eps viewer (evince) to open these two test files.
  
  
https://bugs.launchpad.net/ubuntu/+source/libspectre/+bug/1348384/+attachment/4171120/+files/countrate.eps
  
  
https://bugs.launchpad.net/ubuntu/+source/libspectre/+bug/1242678/+attachment/3886169/+files/test.eps
  
  Rotate test.eps 4 times to ensure that the file still displays correctly
  when rotated. countrate.eps should not have a black background.
  
  Other Info
  ==
  Instead of using the fix from 15.04, 16.04 and 16.10, I chose to use the 
upstream's version of fix-document-rotation.patch included in 0.2.8 and in 
17.04. (fix-document-rotation.patch was the only change made in the original 
SRU)
+ 
+ https://cgit.freedesktop.org/libspectre/commit/?id=38bb113d
  
  Regression Potential
  
  Low. This fix is now in upstream's 0.2.8 and is in Debian and Ubuntu 17.04.
  
  By the way, the 17.04 fix was briefly broken by a ghostscript security
  fix but the 16.04/16.10 fix was not affected. For more details about
  that, see bug 1647917.
  
  Original Bug Report
  ===
  Several eps files, which previously rendered correctly, are not rendered 
correctly by evince and okular.  It looks as though something is wrong with the 
"transparency" setting, since most of the incorrectly-rendered files have a 
black background, but the figure can somewhat be made out on top of hte black 
background.  The PDF files I have tested are NOT affected.  EPS files that were 
previously viewable correctly ARE affected.

[Bug 1348384] Re: evince and okular do not render eps files correctly resulting in a black background

[Till Kamppeter]

The SRU was the simple application of an upstream patch from this
upstream bug report

https://bugs.freedesktop.org/show_bug.cgi?id=76450

I do not know anything of the internals of libspectre and even do not
have upload rights for it, as it does not belong to printing. It is used
by evince to generate certain output data formats. I only have done the
debdiff for that SRU because no one else did it. I am not maintaining
libspectre in Ubuntu.

So my suggestion is to simply remove the patch if the solution of the
current problem is urgent and no better patch from upstream is
available. But take into account that the problem of the original SRU
will reappear. Let this be a new SRU. Wait for a better upstream fix if
it is not so urgent.

In general make upstream aware of both problems and that fix of the
first problem caused the second and what is needed is a fix to solve
both problems. Do another SRU if the final fix is available.

Perhaps it will be fixed for 15.10, or 16.04, or 17.04?

[Bug 1348384] Re: evince and okular do not render eps files correctly resulting in a black background

[Christopher Mendillo]

I just did a fresh install of 14.04.2 from a newly downloaded 14.04.2
iso. This contains libspectre1_0.2.7-2ubuntu1.1_amd64 and produces the
bug.

I tried Corentin's fix to install the vanilla version, but compiling
crashed with:

dpkg-genchanges: error: cannot read ../libspectre_0.2.7-vanilla-0ubuntu1.dsc: 
No such file or directory
dpkg-buildpackage: error: dpkg-genchanges gave error exit status 2


I've gone through all of the ubuntu versions and this is what I get:

libspectre1_0.2.7-2ubuntu1_amd64 -- White background
libspectre1_0.2.7-2ubuntu1.1_amd64 -- Black background
libspectre1_0.2.7-2ubuntu2_amd64 -- Black background
libspectre1_0.2.7-2ubuntu3_amd64 -- White background

So, version 3 works for me, but that is in 14.04.2. I see GrandVizier
has a new problem in 15.04.

I've attached an example eps file that renders correctly in 14.04.2 with
libspectre1_0.2.7-2ubuntu3_amd64.

[John B.]

I know the bug status says Fix Released, but the problem is still
present on new installs of Ubuntu 14.04 (using a 14.04 image and
upgrading all packages, NOT installing from a 14.04.2 image).

Are there any plans to backport/fix this in the LTS release?

I confirm the previous post of GrandVizier.

Incredible that it has been badly fixed !

Previously totally black, the background is totally white.

Please read the ADOBE standard concerning the EPS language before
implementing some hazardous or not professional things !

My linux box is Ubuntu 15.04 (64bits) newly upgraded from 14.10.

[GrandVizier]

libspectre - 0.2.7-2ubuntu3  does not solve the problem for me. 
Rather, it replaces the original problem (black background) with another one 
(nothing displayed, completely white). 
As before, manually adding showpage at the end of the eps file renders 
correctly.
I observe the problem on Ubuntu 15.04 (upgraded form 14.10) and Kubuntu 15.04 
(fresh install).

[Bug 1348384] Re: evince and okular do not render eps files correctly resulting in a black background

[Robie Basak]

I've just spoken with Till about this on IRC.

It seems to me that there are two patches involved here. Patch 1 (fix-
document-rotation) fixed bug 1242678, but caused a regression (tracked
by this bug: bug 1348384). Marek has kindly provided patch 2 (erase-
page) that fixes this.

But patch 1 was reverted upstream, and we don't know what the current
status of this is. So patch 1 has inadvertently caused Ubuntu to diverge
from upstream, and this is what is causing the current pain.

I think that taking patch 2 is going to exacerbate the problem. Then
we'll be even further diverged from upstream, and this will make future
merges harder, which sets Ubuntu up to end up with an old version for
fear of regression.

So to avoid making the situation worse, can someone please resolve the
situation of these two bugs upstream before pushing this patch into
Ubuntu? What has upstream done about bug 1242678? Would it be better to
revert patch 1 from Ubuntu, and take what upstream has done to fix it
instead, thus avoiding this regression altogether and bring us closer to
upstream?

Finally, when preparing debdiffs, please use dep3 headers
(http://dep.debian.net/deps/dep3/) to make it easier to follow upstream
status on these patches.

Thanks.

The patch is a simplified version of the patch

reproduce the problem mentioned by Carlos and my previous patch was

Thanks a lot Corentin. The re-build of a vanilla DEB package solves the 
rendering perfectly.
Your explainations were quite clear...

Edouard

This patch fixes the problem for me. But I can not reproduce the problem
mentioned in https://bugs.freedesktop.org/show_bug.cgi?id=76450#c34 so
there are still some problems probably.

[Bug 1348384] Re: evince and okular do not render eps files correctly resulting in a black background

[Corentin SCHREIBER]

The vanilla libspectre-0.2.7 doesn't show this behavior. The patch we are 
takling about has been introduced in the master branch of the git repository 
last June, but was reverted in September:
http://cgit.freedesktop.org/libspectre

Some time between those two dates, somebody added this patch to the
debian/ubuntu version of libspectre though, and it has not yet been
reverted here.

While this gets fixed, you can get the source of the debian package,
download the vanilla libspectre, and build yourself a new .deb package
without this faulty patch (make sure that the source repositories are
enabled). I give below a script that should do this for you. There may
be a better way, but at least this one works.

# Install the tools needed to build debian packages
sudo apt-get install devscripts
# Install the dependencies of libspectre
sudo apt-get build-dep libspectre1

# Make yourself a temporary directory
mkdir ~/tmp/
cd ~/tmp/

# Download the vanilla libspectre-0.2.7
wget http://libspectre.freedesktop.org/releases/libspectre-0.2.7.tar.gz

# Download the debian source code
sudo apt-get source libspectre1

# Create a new directory with the correct code
cd libspectre-0.2.7
uupdate ../libspectre-0.2.7.tar.gz -v 0.2.7-vanilla
cd ../libspectre-0.2.7-vanilla

# Remove the debian patch
rm debian/patches/*

# Build the package
dpkg-buildpackage -us -uc -nc
# Note: fore some reason, this fails to build libspectre-dev, but we don't care

# Install it
cd ../
sudo dpkg -i libspectre1_0.2.7-vanilla*.deb

[Bug 1348384] Re: evince and okular do not render eps files correctly resulting in a black background

[Achim Bohnet]

So how's fault is it?  Is it in scope of libspectre tasks to add a dummy 
showpage for eps files?  Or have all applications that
use libspectre handle this case themself?

The ubuntu1 ubuntu1.1 diff is here:

http://bazaar.launchpad.net/~ubuntu-branches/ubuntu/trusty/libspectre

I've subscribed Till Kamppeter to this bug, to get his attention.  He
the one that cherry picked the patch.

[Bug 1348384] Re: evince and okular do not render eps files correctly resulting in a black background

[Christopher Mendillo]

Thanks Edouard,

Yes, I can confirm that appending the showpage command to my eps files
causes them to be rendered correctly by evince and libspectre. From what
I can tell reading the latest EPS standard
(https://partners.adobe.com/public/developer/en/ps/5002.EPSF_Spec.pdf),
as you say, showpage is allowed in eps, but should be redefined by
programs that import eps. evince libspectre should do so in order to
display correctly formatted eps files that lack the superfluous showpage
command.

[Bug 1348384] Re: evince and okular do not render eps files correctly resulting in a black background

[EdouardC]

Hi all,

I'm happy to discover that this bug is registrated here. I tried many
times early in july to find some information on the web about this
problem, but I always failed.

In my case (ubuntu-14.04, 64 bits), I discovered and identified this bug
at the end of june.

It appears that it affects only the EPS files which doesn't contain the
'showpage' postscript command at the end of the file. Indeed, a work-
around of this bug is to add the 'showpage' command at the end of the
EPS file.

So, the good new is that a workaround exists and is pretty easy to do:
you can use any text editor to modify an EPS file!

Not all the EPS files are affected: for example the EPS files created
with the Matlab software already include a 'showpage' at the end, so
they are not affected by this bug.

It is worth noting that EPS files which doesn't contain the 'showpage' command 
at their end are valid. Don't answer that these EPS are not valid! The 
'showpage' command is used to eject the page and it is mandatory in PS files, 
not EPS files. Please for example the discussion in:
   http://bugs.launchpad.net/inkscape/+bug/929463
which contain the following extract of the official Adobe documentation:
quote
Redefine showpage

The showpage operator is permitted in EPS files because it is present in so
many PostScript language files. Therefore, it is reasonable for an EPS file
to use the showpage operator, although it is not necessary if the EPS file
will only be imported into another document. The application importing the
EPS file is responsible for redefining showpage. showpage may be redefined
using the following code segment:

/showpage { } def

/quote

Cheers,
EC

[Bug 1348384] Re: evince and okular do not render eps files correctly resulting in a black background

[Christopher Mendillo]

Hi John,

You can download the old package from ubuntu:
http://packages.ubuntu.com/precise/libspectre1

Install with :  sudo dpkg -i libspectre1_0.2.6-1build1_amd64.deb

Do not try and remove the newer 0.2.7 package before you install this
one, that would require you to remove a ton of stuff to satisfy
dependencies.

After installing, you can go into synaptic package manager, search for
libspectre1, click on it, then select Package-Lock Version from the
menu.  That will keep it from trying to update to the new version.

Just a workaround until the problem gets fixed, but I hope it helps.

I just checked, and the prior version of libspectre
(libspectre1_0.2.7-2ubuntu1_amd64.deb), located at:

https://launchpad.net/ubuntu/trusty/amd64/libspectre1/0.2.7-2ubuntu1

renders the eps files correctly.  Thus the bug was introduced in the
change from -ubuntu1 to -ubuntu1.1 as a result of trying to fix Bug
#1242678.

I am experiencing what appears to be the same problem. Just upgraded to
14.04 from 12.04, all of my eps files now have black backgrounds when
viewed with evince. I've attached an example eps file.

The file displays normally with ghostview.

[Christopher Mendillo]

The source of this problem is contained within the libspectre1 library.
This is the evince postscript backend. Between precise and trusty,
libspectre1 was upgraded from 0.2.6-1build1 to 0.2.7-2ubuntu1.1. I
downloaded and installed the previous version from the precise archive
and eps files now render correctly in envice and the thumbnails are
correct, too.

Update manager, of course, now wants to update me back to 0.2.7.

[John B.]

Chris,

Is there a previous version of libspectre1 from the trusty repository?
I've been running 14.04 on this machine, and feel like this is a recent
development.

I will mention that 13.10 did not have this issue either, so the
regression likely happened between the last version supplied to 13.10
and the current version in 14.04.
