A screenshot of the settings I'm pointing at in this bug report
The issue is rather simple but I never stumbled upon it before: when I set the
color scheme of the whole LibreOffice to "LibreOffice Dark", the exported PDF
will have dark background even though the page background has been set to
"none".
How I have set the color scheme:
1. LibreOffice Draw > Tools menu > Options
2. in the left-side menu click on LibreOffice > Application Colors
3. in the "Color Scheme" section and in-front of "Scheme" from the dropdown
menu select "LibreOffice Dark"
4. Click on "Apply" and then the "Ok" buttons at the bottom-right side of the
window
How I have made sure the page background is "transparent:
1. Right-click somewhere outside of any object (e.g move your mouse completely
outside of the page)
2. click on "Page Properties..."
3. in the opened window, navigate to the "Background" tab
4. click on "None"
5. Click on "Ok" button at the bottom-right side of the window
When I open the PDF in Inkscape, there is a dark rectangle at the lowest level
of the imported objects.
As far as I can understand, the logic behind a dark color scheme is not to have
the actual colors of the document messed up, but rather have a dark theme while
working on a document. In LibreOffice Writer or the LibreOffice Calc, the text
that has the color "Automatic" will be displayed with a color that has a good
contrast with the background, but when saved or exported, other people will see
those files based on their own color scheme, even in Microsoft Office. I
completely like this logic and for that reason I strongly believe this is a bug
in LibreOffice Draw.
Also note that I have defined some custom colors in the LibreOffice Dark color
theme (as the section header also clearly implies). The "Font color" is set to
"Automatic", but the "Document background" is set to a color that doesn't hurt
my eyes. Therefore, this bug might have some roots in how the Draw is parsing
the scheme. With the same color scheme, Writer and Calc work beautifully and
without any issues.
Based on my tests, this only happens in LibreOffice Draw, but I might have
missed something, so please also do your testing if needed.
