Re: how to add a font to generate bar codes in my pdfs?

[Raúl Herranz Serrano]

Thanks for your answer... but I have got a question:

Do I overwrite the rest of the fonts (the deafult fonts, I mean...) with the
line "Configuration.put("fonts", allFonts);"?

Thanks again!

It looks like you have the font file ready to go.  To get a barcode in the
PDF, I did the following:

1.  First, here is some sample java code to configure the fonts (you would
probably want to do this dynamically (read better):

Vector allFonts = new Vector();//you may have more than one
Vector allTrips = new Vector();

allTrips.add(new FontTriplet("fre3of9x","normal","normal"));
allTrips.add(new FontTriplet("fre3of9x","bold","normal"));
allTrips.add(new FontTriplet("fre3of9x","normal","italic"));
allTrips.add(new FontTriplet("fre3of9x","bold","italic"));
FontInfo fontInfo = new FontInfo("3OF9X","/fonts/fre3of9x.xml"
,true,allTrips,"/fonts/fre3of9x.ttf");//sample font
allFonts.add(fontInfo);

Configuration.put("fonts", allFonts);


2.  Next, create a text block that uses your barcode font family:

<fo:block font-size="10pt" color="black" font-family="fre3of9x">
112233
</fo:block>

This works for me.

Hi there!

I have the following method in a Servlet that helps me to output pdf files:


    private ByteArrayOutputStream transform(Source xmlSrc, Source xslSrc)
            throws TransformerConfigurationException, TransformerException
{
        ByteArrayOutputStream out = new ByteArrayOutputStream();
        org.apache.fop.configuration.Configuration.put("baseDir",
BASE_DIR);
        Driver driver = new Driver();
        Logger logger = new Log4JLogger(log4j);
        MessageHandler.setScreenLogger(logger);
        driver.setLogger(logger);
        driver.setRenderer(Driver.RENDER_PDF);
        driver.setOutputStream(out);
        TransformerFactory transformerFactory =
TransformerFactory.newInstance();
        Transformer transformer =
transformerFactory.newTransformer(xslSrc);
        Result res = new SAXResult(driver.getContentHandler());
        transformer.transform(xmlSrc, res);
        return out;
    }

The problem is that right now I need to generate some bar codes in my pdfs
and I have think to embed a ttf font in my pdfs that I can use to generate
those barcodes. I have the ttf font file and the xml font metrics file but
right now I don´t know what must I add to the code to be able to use this
font in my pdfs... can you help me?

Thanks a lot!!
