As with everything, there are pros and cons to each approach. ImageMagick tries to do everything, which results in an ever increasing complexity of invocation. Further, if it doesn't do what you want, there's very little you can do about it. Compare that with netpbm, which is just a traditional Unix pipeline. If it doesn't do what you want, you can always add an extra transformation in the middle of the pipeline. Netpbm will often give better quality output (for example, correct gamma scaling).

I agree with you that pdftk is excellent for manipulating pdfs, but why do you say "ImageMagick is rarely the right option anyway"?

Again, I apologize for not being explicit that I was referring to the Gnome release in the upcoming Fedora version. The point was, and remains: that difference is going away, so in a relatively short time that advice will need to be updated, even though it's helpful today. -- Matthew Miller ☁☁☁ Fedora Cloud Architect ☁☁☁ -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

Yes, NetworkManager is the underlying system that takes care of automatically (*) managing the network. And there are various separate things that can be used for the user to interface with it. * To emphasise the point, for those that don't seem to get it, "automatic" means to take predetermined decisions based on provided data (i.e. DHCP, or the lack of it).

There's a difference between talking about what comes next, and just talking about something that isn't in the release yet as if it pertains to an issue someone is having with a current release. i.e. My comment about right-clicking on the icon to get to the configuration options, that seems that nobody on this list with NetworkManager configuration problems EVER bothers to bloody try out before posting messages about it not working.

The Fedora Test List is for discussing all testing of Fedora-related software, not just unreleased distros. The User list (i.e. this one) is for discussing released versions that are still supported. Note that not everyone on the Test list reads the Users list, so posting on Users when you want to comment on unreleased components is going to miss at least some of the audience who might want to read your post (and of course cross-posting is frowned on as well). poc -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

In order to get libsane-hpaio, the part of HPLIP responsible for scanning, to know where the scanner is you have to have a CUPS queue configured for the printer function of the device using the "hp" backend. All libsane-hpaio does for "network scanning" is look through the configured CUPS queues to see which ones have a device URI starting with "hp:/...".

ImageMagik PDF manipulation rotate, thumbnail, problems
I'm writing a fax document import facility. We receive faxes using Hylafax
which get converted to PDF and uploaded to a web server.
My web interface then allows the PDF documents to be split into single pages
and injected into a database.
I create the thimbnails by calling
convert -thumbnail 450 $1 ${1}.jpg
which creates a series of JPEG files one for each page.
Because some people don't know which way up to put pages into a fax machine I
also give the user the ability to invert a fax by calling
/usr/bin/convert $1 -rotate 180 $2
However, the resulting PDF file is very poor quality so I changed this to
/usr/bin/convert $1 -density 300x300 -rotate 180 $2
which fixed the quality in the PDF file which then looks as good as the
original, but is now the right way up.
My problem is then that if I use this new PDF file to create the thumbnails
using the top convert command the resulting image is still the same size, but
the whole of the contents of the page is squashed in the bottom left corner
and the rest of the image is plain while.
Can anyone help with this?
