Remove QT dependency when run from command line

[incidentist]

I want to run Trimage as a command-line tool on a server, but it complains about a lack of QT when I try. It would be great if Trimage didn't use the QT library unless it is needed.

Removing the QT library is a pretty big thing since the threading is managed with QThread, and the command-line tool is just a nice quick add-on to the main GUI. I don't see this happening soon.

Hi, guys! https://github.com/Kilian/Trimage/blob/master/src/trimage/trimage.py#L433 These two lines code (!!!) is all logic Trimage.

Even if QT is present, if $DISPLAY is not set then you get an error message "cannot connect to X server". Is it using some sort of hidden window or something when it runs in command line mode, or could this be fixed?

on CentOS 6.5 it wants to install 40Mb of data, when i run "yum install PyQt4" and im unsure if that is all that needs to be installed..

There should be a disclaimer on the site where anywhere it says CLI it's got fine print "Depends on GUI". Save so much time

I was able to get this to run on google colab by adding the command line option -platform vnc. I can't guarantee that this will work on other headless environments, but for anybody else who's wanting to get this to work in a headless environment it's worth trying this.
