Re: [docbook-apps] Header out of alignment - space before graphic

["Colin Shapiro" <cmshapiro@gmail.com>]

Hi Paul,

I have had this problem before, where I had to set the font-size to 0pt to prevent unwanted space before and after images.

All that it requires is an fo:block with this property:

<fo:block font-size="0pt"/>

If you're customizing the header.content template, simply surround the desired content with one of these fo:blocks; i.e:

<xsl:template name="header.content">
  ...
  <xsl:when test="$sequence = 'first'">
    <fo:block font-size="0pt">
      ...content...
    </fo:block>
  </xsl:when>
  ...
</xsl:template>

I think that will be all that is necessary... by specifying font-size="0pt" on a block within a header table cell, I don't think you will actually need to do anything to the table-cell itself.  If you find that this doesn't work, however, and you'd like to try customizing the table-cell itself, then search 
pagesetup.xsl for the template called header.table.  Copy it to your customization layer, and work with it as necessary.

I hope that helps.

Hi Bob,

Only got back to this problem now.... I tried your suggestion, and the
result is at
http://img175.imageshack.us/my.php?image=headerwithcolorle3.png . It just
seems that something is forcing space before (and indeed, a small amount of
space after) the left-hand graphic. (The yellow and blue colors indicate the
left-most and right-most cells in the header table, respectively, while the
left-hand pink indicates the background of the graphic). Nothing in the .fo
file seemed to indicates where this space is from.

Then I remembered an answer you gave to a previous question I had about
unwanted space before graphics
(http://www.nabble.com/forum/ViewPost.jtp?post=9620007&framed=y)  so I
edited the .fo and, for the header cell containing the graphic, set both
line-height and font-size to zero. That works! Result is here:

Unfortunately, I have _no_ idea how to do this in my custom layer.  The
instructions at
http://www.sagehill.net/docbookxsl/PrintHeaders.html#PrintHeadersText don't
seem to indicate that such a problem might happen, and only describes how to
specify the content of the cells, and not the attributes of the cells
themselves. Any ideas? Is there perhaps a setting in my custom layer which
is causing this problem?

Thanks,

P.
