Hello @Fleik and welcome to the forum.
- Collabora Online Version COOLWSD : 21.11.5.2
Whoa, that one is old (~June 2022).
You probably want to upgrade to the latest 23.05 versions. I’m betting your bug is already fixed.
I tested background images in:
- COOL 23.05.6.4
- LibreOffice 7.6.4.1
and they worked. (See steps below.)
I translated your message from French->English through DeepL:
So, if I’m understanding you correctly…
In Writer, you are:
Setting a Background Image
-
Go to “Layout” tab.
-
Press “Page” button.
-
Go to “Area” tab.
-
Click “Image” button.
- (Leaving it on default settings?)
- Press OK.
Then you are:
- Saving as ODT.
- Opening ODT in LibreOffice.
And then your:
- LibreOffice doesn’t have a full background image.
I just tested all my steps, and it worked fine using the latest Collabora + LibreOffice:
