Thanks, Barris.

I do have Version: ImageMagick 6.9.7-4 with convert.

Did you mean to put this in the extra flag line? >


  * To "Converter:" write :|convert -density *** -trim -quality 100
    -sharpen 0x1.0 $$i $$o|, where *** can be 200 to start with. You may
    try other values based on the results.

  * Click "Save" button.

There was no save button, I clicked ok

I opened my document. Now instead of

/error converting in a loadable format/.

I get

/error loading file into memory

What I plan to do now is to try it with Debian buster on my notebook. I 
am currently on Linux Mint Tina using my PC.
