Fedora 7 - missing options?

[iflower]

Been playing around with ImageMagick and the examples found on the project page there. However I seem to be missing a few command line options.

For example the examples us an options -distort with convert. Command fails with unrecognized option distort. "convert -list distort" also fails to find the option, and its not listed on the man pages of my Fedora 7 install.

Is this part of an experimental packages, and would I have to compile from ImageMagick source to get "all" options for ImageMagick?

It depends what version you are running, I think the distort options came in around 6.3.5

I have just started playin with Linux but you should be able to update your installation with "Add remove software" or yum update imagemagick ?

Ah, so thats the reason, FC7 currently have 6.3.2 as its latest version. Just have to be patient and wait then. Or upgrade to fc8 in a few weeks.

I was under the impression that distort entered ImageMagic some time ago, so thats the reason for my confusion.

You could run this and see if it is available:

Code: Select all

convert -list Command

The -distort operator is relatively new and was added late in 6.3.5, with lots of work and updates in 6.3.6. The IM in Fedora 8 should be much newer. Alturnative you can built a RPM using the very latest IM RPM sources to be right up to date. See

Before this distortions were done using a slow -fx DIY method. The examples of this is still present in a sub-page of IM Examples, until I get time to go though them properly to see how relevant they are.

At the moment I am concentrating on Resize filters and then improvements in the image resampling sub-system used by distort to try and remove the existing fuzziness that is appearing. After this I have further work in the handling of the extreme limits for tiled perspective views, before I an finally start adding more distortion methods.

Still lots to do, and it all takes time.
