Embedding Font into Apache FOP

Question

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:

Dont mind the URLs.

Answer 1

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.

Answer 2

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 -

1. 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
2. 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 -

1. create conf\fop.conf

2. Put the configuration to enable auto-detect for pdf fonts inside conf\fop.conf

3. 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.
