<para>Page headers in print output use a three column table
|
||
|
|
to position text at the left, center, and right side of
|
||
|
|
the header on the page.
|
||
|
|
This parameter lets you specify the relative sizes of the
|
||
|
|
three columns. The default value is
|
||
|
|
"1 1 1".</para>
|
||
|
|
|
||
|
|
<para>The parameter value must be three numbers, separated
|
||
|
|
by white space. The first number represents the relative
|
||
|
|
width of the inside header for
|
||
|
|
double-sided output. The second number is the relative
|
||
|
|
width of the center header. The third number is the
|
||
|
|
relative width of the outside header for
|
||
|
|
double-sided output.
|
||
|
|
</para>
|
||
|
|
<para>For single-sided output, the first number is the
|
||
|
|
relative width of left header for left-to-right
|
||
|
|
text direction, or the right header for right-to-left
|
||
|
|
text direction.
|
||
|
|
The third number is the
|
||
|
|
relative width of right header for left-to-right
|
||
|
|
text direction, or the left header for right-to-left
|
||
|
|
text direction.</para>
|
||
|
|
|
||
|
|
<para>The numbers are used to specify the column widths
|
||
|
|
for the table that makes up the header area.
|
||
|
|
In the FO output, this looks like:
|
||
|
|
</para>
|
||
|
|
|
||
|
|
<programlisting>
|
||
|
|
<fo:table-column column-number="1"
|
||
|
|
column-width="proportional-column-width(1)"/>
|
||
|
|
</programlisting>
|
||
|
|
|
||
|
|
<para>
|
||
|
|
The <literal>proportional-column-width()</literal>
|
||
|
|
function computes a column width by dividing its
|
||
|
|
argument by the total of the arguments for all the columns, and
|
||
|
|
then multiplying the result by the width of the whole table
|
||
|
|
(assuming all the column specs use the function).
|
||
|
|
Its argument can be any positive integer or floating point number.
|
||
|
|
Zero is an acceptable value, although some FO processors
|
||
|
|
may warn about it, in which case using a very small number might
|
||
|
|
be more satisfactory.
|
||
|
|
</para>
|
||
|
|
|
||
|
|
<para>For example, the value "1 2 1" means the center
|
||
|
|
header should have twice the width of the other areas.
|
||
|
|
A value of "0 0 1" means the entire header area
|
||
|
|
is reserved for the right (or outside) header text.
|
||
|
|
Note that to keep the center area centered on
|
||
|
|
the page, the left and right values must be
|
||
|
|
the same. A specification like "1 2 3" means the
|
||
|
|
center area is no longer centered on the page
|
||
|
|
since the right area is three times the width of the left area.
