问题
I am tring to get Apache FOP to use Arial as font. So far, without luck.
In my config.xml it says:
<fonts>
<font kerning="yes" embed-url="file:///C:/Windows/Fonts/Arial.ttf" encoding-mode="auto">>
<font-triplet name="Arial" style="normal" weight="normal"/>
</font>
</fonts>
But it doesnt seem to work. When I start FOP on the command line it says font Arial normal not found.
I have tried to generate the Arial.xml file from the ttf with TTFReader in FOP but that, too, hasnt worked (even following the instructions on the fop webpage). I get the following error message:
C:\Users\xy\Desktop\FOP2>java -cp build\fop.jar;lib\avalon-framework-4.2.0.jar;lib\commons-logging-1.0.4.jar;lib\commons-io-1.3.1.jar org.apache.fop.TTFReader C:\Windows\Fonts\arial.ttf Arial.xml

Maybe Im not seeing the forrest for the trees, but I'm at a loss as to what to do.
Any suggestions?
UDPDATE:
- I downloaded a lot of xml-Files from this site: http://www.java2s.com/Code/Jar/f/Downloadfopfontmetricsjar.htm (which to me look a lot like the xml-files that were already in fop. so I assume they are in the correct format)
I put them in the folder fop/src/codegen
I also put the arial.tff there
in the file fop/conf/xconf it says
<fonts>
<directory>C:\Windows\Fonts</directory>
<!-- embedded fonts -->
<!--
This information must exactly match the font specified
in the fo file. Otherwise it will use a default font.
For example,
<fo:inline font-family="Arial" font-weight="bold" font-style="normal">
Arial-normal-normal font
</fo:inline>
for the font triplet specified by:
<font-triplet name="Arial" style="normal" weight="bold"/>
If you do not want to embed the font in the pdf document
then do not include the "embed-url" attribute.
The font will be needed where the document is viewed
for it to be displayed properly.
possible styles: normal | italic | oblique | backslant
possible weights: normal | bold | 100 | 200 | 300 | 400
| 500 | 600 | 700 | 800 | 900
(normal = 400, bold = 700)
-->
<font metrics-url="C:\Users\z003a5bp\Desktop\FOP2\src\codegen\fonts\arial.xml" kerning="yes" embed-url="C:\Users\z003a5bp\Desktop\FOP2\src\codegen\fonts\arial.ttf">
<font-triplet name="Arial" style="normal" weight="normal"/>
<!-- <font-triplet name="ArialMT" style="normal" weight="normal"/> -->
</font>
<!-- <font metrics-url="arialb.xml" kerning="yes" embed-url="arialb.ttf">
<font-triplet name="Arial" style="normal" weight="bold"/>
<font-triplet name="ArialMT" style="normal" weight="bold"/> -->
<auto-detect/>
</fonts>
So ive got auto-detec and specified a directory for the fonts and embedded arial - stil I get error messages like "glyph xyz is not included in Helvetica" although nowhere in my stylesheets does it say font-family Helvetica. The pdfs are displayed in Times New Roman...
++ UPDATE ++
Okay...
my fop.xconf file says this now:
<fop version="1.0">
<base>.</base>
<source-resolution>72</source-resolution>
<target-resolution>72</target-resolution>
<default-page-settings height="11in" width="8.26in"/>
<renderers>
<renderer mime="application/pdf">
<filterList>
<value>flate</value>
</filterList>
<fonts>
<font metrics-url="file:///C:/Users/z003a5bp/Desktop/FOP2/src/codegen/fonts/arial.xml"
kerning="yes"
embed-url="file:///C:/Users/z003a5bp/Desktop/FOP2/arial.ttf">
<font-triplet name="Arial" style="normal" weight="normal"/>
</font>
<auto-detect/>
</fonts>
</renderer>
I've added font-family="Arial" to pretty much all the elements now :D
I go to my fop directory in the command line and enter
fop -xml blabla\file.xml -xsl blabla\stylesheet.xsl -pdf output.pdf
And i get the following:

I had the same Problem, using FopFactory from .NET and solved it whith the java example on the Apache doc: http://xmlgraphics.apache.org/fop/1.1/embedding.html#config-external
I created a config file with this code:
<?xml version="1.0" encoding="utf-8" ?>
<fop>
<renderers>
<renderer mime="application/pdf">
<fonts>
<auto-detect/>
</fonts>
</renderer>
</renderers>
</fop>
Then added it info FopFactory:
FopFactory fopFactory = FopFactory.newInstance();
fopFactory.setUserConfig("fop.xconf");
The option "auto-detect" is for detecting all fonts on the system and it may takes a while and the output has a big size. To configure a specific font from the system, see the doc in the link above.

I had exactly the same issue (although s/Arial/Verdana/ and fwiw - fop-2.1 on Windows). After trying various things, and then taking a step back, i discovered i was making the same mistake as a number of us have -
- I was editing the supplied/example configuration file that has the non-default extension and therefore is not automatically used by fop i.e. fop.xconf
- fop.bat (or any of the other supplied platform invocation scripts) does not invoke org.apache.fop.cli.Main with -c fop.xconf, or -c with any .conf file, so any changes to fop.xconf are not used
The solution that worked for me was -
- create
conf\fop.conf Put the configuration to enable auto-detect for pdf fonts inside conf\fop.conf
Ensure you are supplying fop with the conf file i.e. call fop.bat (or other platform script) with the -c option e.g. -
fop.bat -fo path\to\fo.fo -c path\to\fop.conf -pdf path\to\output.pdf
As i was saying before, we're not alone in being caught out by this, see e.g. -
How can I embed a base14 font in a pdf
Embedded font don't work in Apache FOP
IMHO - I think we wouldn't have all got caught out by this if Apache FOP was distributed with an empty fop.conf that was already referenced in the invocation scripts.
回答3:
For historical reason, Helvetica is the default font for postscript on which FOP PDF rendering is based off. As an outcome, if you do not explicit declare a font in your XSL templates, FOP will try to use Helvetica.
So my Problem was FOP trying to embed Helvetica font when generating a PDF/A document, but Helvetica is never declared in templates nor installed on my Linux system.
Solution was simple, I mapped a substitution for Helvetica in my fopconf.xml and made LiberationSans my default font that way. Example fopconf.xml:
<fop version="1.0">
<renderers>
<renderer mime="application/pdf">
<fonts>
<!-- auto-detect operating system installed fonts -->
<auto-detect />
<!-- substitute default unfree font Helvetica with free font LiberationSans
(which is an Arial Clone, which is an Helvetica Clone) -->
<substitutions>
<substitution>
<from font-family="Helvetica" />
<to font-family="LiberationSans" />
</substitution>
</substitutions>
</fonts>
</renderer>
</renderers>
</fop>
The alternative solution for templates that do use other fonts, was setting the font-family directly on the root element like <fo:root font-family="LiberationSans">.
Hope my answer adds some additional value to this question.
[UPDATE]I might add, that I am using FOP 2.1[/UPDATE]

The "ClassNotFoundException" indicates that you have a class loading problem. Given that it's missing "org.apache.xmlgraphics.fonts.Glyphs", it means you don't have xmlgraphics-commons.jar in your classpath (or an outdated version). You'll find that in FOP's "lib" directory.
回答5:
I just thought I would add a partial solution here for people who are still wondering about this, to generate the xml file, you also need to add xmlgraph_commons-1.4.jar to the classpath.
Also, the path to the application is org.apache.fop.fonts.apps.TTFReader, not what the OP posted, at least in older versions of fop.
Here is a working export
java -cp build\fop.jar;lib\avalon-framework-4
.2.0.jar;lib\commons-logging-1.0.4.jar;lib\commons-io-1.3.1.jar;lib\xmlgraphics-
commons-1.4.jar org.apache.fop.fonts.apps.TTFReader C:\Windows\Fonts\arial.ttf A
rial.xml
