ImageMagick 6 and 7, or just 7?


I just successfully installed ImageMagick 7 on Ubuntu 18.10.

What is suggested, to have both versions, 6 and 7, or just the newer 7 version?

I am a regular desktop user which works as web admin and designer, but no scripting involved. I’m also a newbie as sysadmin, so advanced scripting for my server is in the mid-term future.

Thank you for using our forum.

I might not have a very strong opinion on this one, but there is no harm to keep both versions unless your are running out of the disk space. Any chance that you may need to use the 6 version?

The version 6 is still available on your system and can be accessed via imagemagick commands with suffix -im6. So for imagemagick 6 use commands:

$ ls /usr/bin/*-im6.q16
/usr/bin/animate-im6.q16    /usr/bin/convert-im6.q16   /usr/bin/mogrify-im6.q16
/usr/bin/compare-im6.q16    /usr/bin/display-im6.q16   /usr/bin/montage-im6.q16
/usr/bin/composite-im6.q16  /usr/bin/identify-im6.q16  /usr/bin/stream-im6.q16
/usr/bin/conjure-im6.q16    /usr/bin/import-im6.q16 

For example:

$ identify-im6 --version
Version: ImageMagick 6.9.7-4 Q16 x86_64 20170114


$ identify-im6.q16 --version
Version: ImageMagick 6.9.7-4 Q16 x86_64 20170114

The bottom line is that there is not harm for keeping them both.

Hope this helps…
