Subject RE: FOP trunk error message when run from ant
Date Fri, 02 Jul 2010 12:41:30 GMT
I'm not suggesting that it wouldn't work, just that it sounds like some
ugly hack to combine the two methods, that the xconf file should be
required if you're calling FOP from a command prompt and if you're using
the classes with embedded code you could skip the xconf file and use the
proper code to import the font with the FontLoader.

In my case there's an additional benefit to using the FontLoader,
because I'm using the classes in embedded dynamic code.  I wrote a
program which puts all the data to be printed into an XML file.  It
writes the data with made up tags to specify coordinates on a page to
print each piece of text with absolute locations.  I tell it how many
characters I want to print across the page and it dynamically adjusts
the font size to fit.  I'm using a fixed point font, so I get the font
size from the TTFLoader.  It reads the font into a CustomFont which
implements FontDescriptor which extends FontMetrics which has a method
getWidth.

Eric,

In our case, we get data from database as XML, apply the reports
specific xsl-fo template (.xsl file) and generate a PDF report. That's
our requirement and the solution I mentioned works very well for us.

All we need is create FOP Factory instance, specify the configuration
file location, specify transformer (XSLT), provide source XML file and
we have what we need a PDF report.

Also we keep our application related fonts in a separate folder than
windows folder.


Regards,
Jayant

That doesn't seem right at all.  You explain how to get the fonts into
the xconf reference path then show an embedded example.  If you're using
the classes and embedding the code you don't need that.

I pull in fonts like this:
1) Create a TTFFontLoader using the font file name with URI path and a
DefaultFontResolver
2) If it's one font per file just use getFont() to create a CustomFont,
if you need to query any font details from the file
3) Build a new FontTriplet and add it into a Java ArrayList
4) Create a new EmbedFontInfo object using the FOP generated metrics
file (URI), the KerningEnabled value (can be queried from CustomFont),
the font triplet array, the font file (URI), and the sub font name (may
be null)
5) Create another Java ArrayList and add in the EmbedFontInfo
6) Generate a Renderer and pass the font ArrayList to setFontList()
7) Put the Renderer into the UserAgent (setRendererOverride) Then you
shouldn't even need the xconf file.

I suggest never referring to fonts as files which should be installed on
the client OS.  We had a program years ago running on Windows 98
referencing a Courier font that didn't come out right because somehow
the same font file had a different looking font in it on different
clients.  I avoid that problem now pulling the font from the server.

Mario,

Here's how I am using custom fonts.


In my application folder I have created a folder "MyAppFonts" and copied
all custom fonts in that folder. You can either refer to operating
systems folder such as c:\windows\fonts.

Copy fop.xconf file to your application folder and then rename to
YourAppNameConfig.xml

Open the YourAppNameConfig.xml in any editor and add you MyAppFonts
folder as shown below

      <fonts>
        <!-- embedded fonts -->
                    <!-- register all the fonts found in a directory -->
                    <directory>.\MyAppFonts</directory>

                    <!-- register all the fonts found in a directory and
all of its sub directories (use with care)
        -->
                    <directory recursive="true">.\MyAppFonts</directory>

                    <!-- automatically detect operating system installed
fonts
                    <auto-detect/>
        -->
      </fonts>


Sample java code

            // configure fopFactory as desired
            FopFactory fopFactory = FopFactory.newInstance();

            fopFactory.setUserConfig(new File( YourAppNameConfig.xml ));

            FOUserAgent foUserAgent = fopFactory.newFOUserAgent();


I am using custom font in this manner.

I hope this information helps.

Jayant
