[SOLVED] Problem with okular (or ghostscript ?)

Toutatis · 04-09-2013, 04:14 AM

When opening ps files with okular (from slackware64-current, kde-4.10.2), I get blank pages and messages of this type:
------------------------------------------------------------
okular(32278)/okular (Spectre) GSRendererThread::run: Generated image does not match wanted size: [0x0] vs requested [926x1308]
QImage::scaled: Image is a null image
undefined -21
undefined -21
okular(32278)/okular (Spectre) GSRendererThread::run: Generated image does not match wanted size: [0x0] vs requested [53x75]

------------------------------------------------------------

But the ps files open correctly with gv or gsview.

Any idea ?

Are the images displayed with gv with you're files?
I can open these ps files from the link with no problem
and I have the same version.

can you do that to?

I can open 'testprinter.ps' with gv, but with okular I get only a blank page and a lot of messages like this

I have tried to reinstall okular, ghostscript, poppler, libspectre with no result.
evince shows the same as okular.
But gv, gsview, mgv (an old postcript viewer) work well.

testprinter.ps works fine here with okular, the only guess I can do is that you're probably not using a full install.

to fix this, run

Code:

slackpkg install slackware64

Thank you for your answers. All my packages are updated.

I downgraded 'ghostscript-9.07-x86_64-1' to 'ghostscript-9.05-x86_64-3' and now it works....

Just because, I downloaded testprinter.ps and opened it with Okular:

Code:

okular testprinter.ps

The file displayed all right, but the above stuff doesn't look all that good, eh? I'm using Xfce although KDE is fully installed; will wonders never cease (this is Slackware 64-bit stable).

Ghostview: no errors, works just fine, with these:

Code:

[
/var/log/packages/gv-3.7.3-x86_64-2
/var/log/packages/gvfs-1.12.3-x86_64-2

Ghostscript is at 9.06, no problems.

The problem is now solved with new ghostscript-9.07-x86_64-2 in slackware64-current.
