In Libreoffice Writer:
Currently there is a Character style checkbox named “Outline” under “Font Effects” .
That effect will convert the filler of the character into white, while only a thin black “character-border” will stay.
I want exactly the opposite:
Having the standard black filler to stay in each character, while only providing an additional “character border” which has a white color.
The purpose of this is to ensure that the characters are easily readable - because I want to stamp them on another PDF.
