Q:

Decorative, graphical horizontal separators in Libreoffice Writer v5

Using LibreOffice Writer 5.0.3.2, I'd like to create a decorative, graphical horizontal separator between sections of text. A nearly duplicate question in the TeX StackExchange gives this example:

... though unlike that example, I will use the same image every time.
I can get a plain horizontal line by typing --- and letting AutoFormat set the "Horizontal Line" style, which uses borders to produce the line.  However I'd like to set a style that instead uses a single, elongated graphic.  (This is not the same as repeating tiny icon along a line.)
Extra points if LibreOffice comes with a set of graphics for this purpose, but otherwise I'm fine providing my own graphic.  My goal is to make this a reusable style where I don't have to "Insert > Image" and worry about anchoring and alignment every time I use this same element.

A:

Create a new style (or Modify the existing "Horizontal Line" style).
On the Area tab of paragraph settings:

Fill = Bitmap
Import Graphic... to choose the image to use (you must provide your own).
Probably want to un-check Tile and AutoFit.
(The Position, X- and Y-offset boxes only apply to tiling, so are useless unless you checked Tile.)

On the Font tab, choose a tall enough font size to fit your entire decoration. We won't actually be typing text in this style though.
To avoid an endless stack of dividers, on the Organizer tab, set the "Next style" to that of the text you want to follow the divider.

Now when you want a divider, simply insert a new line in your document and set its style to this one.
