Redmine

Hello everyone!

As per the installation documentation online, when installing Redmine you should install RMagick (and the imagemagik system package, although it's not mentioned) when installing versions prior to 4.1 to be able to export gantt charts to PNG or PDF. But when installing Redmine version 5.x you can/should use Ghostscript to enable thumbnails generation for PDF attachments in Redmine 4.1 or later.

My Redmine 5.0.3 installation has mini_magick installed, which enables the "MiniMagick available (optional)" entry in the installation info page, and it also has the "ImageMagick PDF support available (optional)" entry because I installed the ghostscrit system package, but the "ImageMagick convert available (optional)" entry is not active because I didn't install the imagemagick system package.

This is kind of confusing in my opinion and the installation docs should be updated to reflect more clearly what you get and what you don't when installing (or not) certain packages.

In the end, I installed imagemagick on my Debian 11 Bullseye for the convert command to be available (and a huge number of dependencies that come with it). Nothing wrong with that, albeit a tad less optimal maybe, but it would be great for new users to be given clearer messages regarding these optional dependencies (i.e. imagemagick and ghostscript system packages).

Thanks and keep up the good work.
