xmlroff-logo-font-size

To do the deed, I added some XSL attributes to the <inline-graphic> element in my well-formed XML.  I also made an entity declaration for &xmlroff; so I wouldn’t have to repeat the markup each time (and so, having got it right once, it would be right everywhere).

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE poster [
<!ENTITY xmlroff '<inline-graphic src="xmlroff.svg" alignment-adjust="-22.5&#37;"
height="from-parent(&apos;font-size&apos;)"/>' >
]>
<poster>
<title>Using XSLT in &xmlroff; for C Code Generation and XSL FO Testing</title>
<body>
<intro>
<para>&xmlroff; (http://xmlroff.org) is a fast, free, high-quality,...

where:

  • height="from-parent(&apos;font-size&apos;)" sets the graphic height to the current font-size
  • alignment-adjust="-22.5&#37;" (where “&#37;” is the numeric reference for “%”) moves the bottom of the graphic down so the baseline of the logo text lines up with the baseline of the regular text. When the alignment-adjust value is a percentage, it is calculated relative to the height, so it remains correct when the font size changes.

The XSL attributes are just copied through when transforming to XSL FO:

<xsl:template match="inline-graphic">
  <fo:external-graphic
    src="url('{@src}')"
    xsl:use-attribute-sets="graphic-atts"
    content-height="scale-to-fit"
    content-width="scale-to-fit"
    scaling-method="resample-any-method">
    <xsl:copy-of select="@height | @width | @content-height | @content-width |
@scaling-method | @alignment-adjust"/>
  </fo:external-graphic>
</xsl:template>

The result is slightly more interesting text, but also more readable where sentences and paragraphs that started with the all-lowercase “xmlroff” now start with the xmlroff logo.

http://xmlroff.org/download/xmlroff-0.6.2.tar.gz and
http://xmlroff.org/download/libfo-examples-0.6.0.tar.gz

libfo-examples 0.6.0 adds xmlroff-gtktree as a work-in-progress
demonstration of using a GTK+ tree widget to view the FO tree with what
will eventually be a side panel showing the current FO’s properties.

xmlroff 0.6.2 really only has some changes in the header files necessary
to support libfo-examples 0.6.0.

The next xmlroff version will be 0.7.0, which will have some support for
static fo:static-content.

xmlroff 0.6.1 features SVG external graphics rendered as vectors in the Cairo backend and table column order respecting writing mode.

Thanks go to lode leroy for the Cairo fix.

Instead of my reciting the list of packages that you need to build xmlroff, I just need to tell you to install it from the ‘universe’ repository using the Synaptics package manager.

Thanks must go to W. Martin Borgert and others of the Debian XML/SGML Group for doing the packaging work so that Ubuntu could pick it up as well as to the Ubuntu folks for including it.

This release fixes some table bugs and adds linefeed-treatment and white-space-collapse properties (actually added in 0.5.3, but that release was only announced on the xmlroff-list).

Starting with a clean installed system, install the following packages (and their dependencies):

  • libtool
  • autoconf
  • automake1.9
  • libglib2.0-dev
  • libxslt1-dev
  • libcairo2-dev and/or libgnomeprint2.2-dev

In five-or-so years on SourceForge, xmlroff garnered 24 bug reports. In the couple of months since moving everything to xmlroff.org, xmlroff has already amassed over 60 Trac tickets.

It may look as if xmlroff is suddenly much buggier, but it’s due to finally having a bug reporting system that’s easy to use.

Because it’s easier to use, we use it more. There’s been tickets for moving to xmlroff.org and for pie-in-the-sky ideas like a Texinfo-XML-to-FO stylesheet as well as for common or garden bugs. Since it’s also easy to link to bug reports, there’s now more ticket numbers in the notes on test results and in commit messages.

The proliferating tickets and ticket references point to quality improving, not worsening. After all, we’ve also closed more tickets than xmlroff had bug reports while on SourceForge.
