#219956 — downgrade ghostscript to get convert etc working

It seems convert doesn't work on Debian Buster, I get an error for
this command

  convert -composite $bg $fg -gravity center comp.png
  
namely this message: "convert-im6.q16: no images defined `comp.png'
@ error/convert.c/ConvertImageCommand/3258."

I heard the solution is downgrade ghostscript but
'aptitude versions' only shows one version, 9.27 (or
9.27~dfsg-2+deb10u3).

Do I need to add additional sources or how do
I downgrade to a version that doesn't have the bug?

TIA

The solution is *not* to downgrade: It is a security-related change.

The solution is therefore to fix the Postscript code.

That said, if you insist on doing a potentially dangerous _workaround_ 
then there's https://snapshot.debian.org/

OK, but here they say:

    Debian Buster (10) just came into Soft Freeze stage, after Full
    freeze it will be too late and this newly introduced bug will
    not be fixed for Debian Buster ...

    Have you tried downgrading from GS 9.26 to 9.23 or 9.24. I have
    heard of issues with 9.26 ...

Hello,

I have not tried this and do not use imagemagick directly (it is
installed as a dependance on my system): perhaps you can deinstall
imagemagick and install graphicsmagick-imagemagick-compat instead?

(Sorry, Emmanuel, my mistake, I dit click on "answer" and sent tp you a
private mail)

Couldn't he just edit the policy.xml file? Or is this unrelated to
the "not authorized" error I've seen elsewhere.

If the newer version (currently v9.50 in bullseye (testing)) would solve 
the problem, then you may want to ask if someone could place this newer 
version from bullseye into the buster-backports repository. Afterwards 
you could install the backported version 9.50 from there without hassle. 
This would be the Debian way to follow first. Only if not succeeding 
this way, then think about tinkering.

More information on this concept can be found here:
https://backports.debian.org/
The corresponding mailing list is this one:
https://lists.debian.org/debian-backports/

Good luck! Marco.

Above advice is sensible in general.

For this particular issue, look into upgrading _other_ parts of the 
command chain than Ghostscript, however (as per my previous post).

#219983

Has this problem been mentioned in the BTS, you think? I found
this [1] but no one seems to match this situation exactly what
I can see (?)

Can any of you guys reproduce it? I'm on buster [2] with
imagemagick 6.9 [3]

command:

  convert -composite bg.png fg.png -gravity center out.png

error message:

  convert-im6.q16: no images defined `comp.png' @ error/convert.c/ConvertImageCommand/3258.

No.

For gravity to work, I had to place it first, otherwise I get
northwest. I just used a couple of screenshots and a couple
of PDFs, placing the smaller on the larger each time.

PS your kernel is out-of-date.
