Items 1
-3
are set at Page Style dialog’s Page
tab.
Items 4
-8
are defined on tab Borders
.
Items 9
-12
are from Header
tab.
Items 14
-19
are on Border tab of the dialog available by clicking on More...
button on Header
tab of Page Style dialog.
Item 13*
is not defined explicitly; see its discussion below.
Items 4
and 14
are measured in points (pt = 1/72 in); units of other items follow user preferences (Options
▸LibreOffice Writer
▸General
).
Most of the elements are quite straightforward and obvious from the schema and their naming; possibly the not-so-obvious fact needs mentioning that border widths are added to the spacings; and that 12
= 14
+ 18
+ 13*
+ 19
+ 14
+ 15
. However, there are two options on the Header
tab, that affect items 11
, 12
, 13*
, and need additional explanation, namely:
[ ] Use dynamic spacing
[ ] AutoFit height
When both of these checkboxes are unchecked, the values of items 11
(Header spacing) and 12
(Header height) are used strictly as set. Any content of header’s text area (13*
) that doesn’t fit will be cut off.
When AutoFit height
is checked, 12
is considered minimal height of the header: if text contents doesn’t fit into 13*
that results from the set elements’ sizes, it will expand the height downwards as needed, shifting 11
downwards (height of 11
is unchanged) and decreasing main page text body height.
When both AutoFit height
and Use dynamic spacing
are checked, then the height of 12
is also minimum, and grows when 13*
needs; but when growing, initially it borrows space from 11
(header spacing), thus the total height of 11
+ 12
doesn’t change, and main page text body’s top doesn’t move. Only when header spacing is depleted, further growth of 13*
(and 12
) will start borrow space from main page text body height.
Checking Use dynamic spacing
alone doesn’t make sense, and behaves as if 12
is set to 11
+12
, and 11
is set to 0.
