Change the header/footer size in a PDF
Hi,
I have a simple XSL report with header, body and footer which renders to a
PDF. My Java application passes variables to the XSL to set body-margin,
header/footer-extent and font sizes.
I set the header size (in point not mm) to be slightly larger than the font
size for text to appear in the header. This works fine - gives enough space
for the header to hold all the text.
However, if the text in the header (which is set by a user back in the
application) is "longer" than the width of the header, that text will carry
over to a next line...and so bleed into the body.
I've seen this post from a while back
http://www.nabble.com/Auto-size-header-to-fit-with-content---td4765740.html#a4765740
...but it doesn't really help. Hardcoding for line height, text height,
etc, etc is too dangerous.
I've scoured the FOP Javadoc and cannot seem to figure out if it's possible
to access the rendered PDF (as some sort of tree or data object) and work
out if the header text has wrapped. Is it possible to determine this and so
fix it?
Or is it possible to access the PDF itself and determine if wrapping has
occurred in the header?
If I can detect the header has wrapped text (or footer for that matter), I
can just increase the header by the original amount and re-render to PDF.
Thanks in advance,
Bernmeister.

Hi Bernmeister,
The one thing I see: the second parameter to evaluate, item, should not be a String but the root node of your document.

Hi Georg,
Thanks again for your help. Getting there slowly...
I believe I've managed to get to the point of getting a document back from the transformation. The code is below:
FopFactory fopFactory = FopFactory.newInstance();
FOUserAgent foUserAgent = fopFactory.newFOUserAgent();
SAXTransformerFactory saxTransformerFactory = (SAXTransformerFactory)TransformerFactory.newInstance();
TransformerHandler transformerHandler = saxTransformerFactory.newTransformerHandler( new StreamSource( m_xslStylesheet ) );
DOMResult domResult = new DOMResult();
transformerHandler.setResult( domResult );
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
BufferedOutputStream bufferedOutputStream = new BufferedOutputStream( new FileOutputStream( m_outputPDFFile ) );
Fop fop = fopFactory.newFop( MimeConstants.MIME_FOP_AREA_TREE, foUserAgent, bufferedOutputStream );
Transformer transformer = saxTransformerFactory.newTransformer();
// Set report parameters...
Set<String> xslKeys = m_xslParams.keySet();
for( String xslKey : xslKeys )
transformer.setParameter( xslKey, m_xslParams.get( xslKey ) );
Source source = new StreamSource( m_xmlData );
Result result = new SAXResult( transformerHandler );
saxTransformerFactory.newTransformer().transform( source, result );
Document document = (org.w3c.dom.Document)domResult.getNode();
XPathFactory factory = XPathFactory.newInstance();
String expression = ".//block[@id='" + "HeaderID" + "']/@bpd";
String item = "fo:block";
QName returnType = XPathConstants.NUMBER;
Object returnValue = factory.newXPath().evaluate( expression, item, returnType );
double height_in_milipoints = Double.parseDouble( (String)returnValue );
The for loop is used to set report parameters such as page size, page margins, report title, etc.
When I run the above code, I get an XPathExpressionException. Unfortunately there is no detailed message.
The snippet of my XSL file is:
<fo:static-content flow-name="xsl-region-before">
<fo:block id="HeaderID" font-family="{$header-font-family}"
font-size="{$header-font-size}" font-style="{$header-font-style}"
text-align="center"><xsl:value-of select="$report-title"/></fo:block>
</fo:static-content>
I'm not sure what I am doing wrong. When I debug the Java and inspect the "document" variable it seems to have lots of stuff - but can't actually figure out how to locate the node I want.
If easier or you prefer, send me a direct email and we can then work out how to IM each other.
Thanks again,
Bernmeister.

Hi Bernmeister,
Nope, sorry, I already send in the transformed fo file. But it hardly matters. You don't change the input, you don't change the process, you only change the output format and the result:
DOMResult domResult = new DOMResult();
handler.setResult(domResult);
Fop fop = getFopFactory().newFop(MimeConstants.MIME_FOP_AREA_TREE, foUserAgent);
And then you get the result for further processing:
return (org.w3c.dom.Document)domResult.getNode();
For the xpath stuff you create your xpath object:
XPathFactory factory=XPathFactory.newInstance();
XPath xPath=factory.newXPath();
and ask it for the height:
double height_in_milipoints = xPath.evaluate(".//block[@prod-id='"+<your id>+"']/@bpd", <your document root>, XPathConstants.NUMBER)
That should be the difference to what you already have for PDf generation.
Mit freundlichen Grüßen
Georg Datterl

I must admit I'm not too familiar with java.xml.* package - just able to render out a PDF and that's it. So I'm having difficulty following your example.
Assuming I have a template.xsl file and a data.xml file, I assumed I would have to simulate/emulate using FOP to transform the data.xml via the template.xsl into a PDF (or really a tree in memory).
In your example I follow that the xsl is passed in...but I don't see how/where the data.xml would come into it.
If this is not the right forum, any ideas where/who I should try?
Thanks again!

Hi Bernmeister,
You can do that. Take the block element, where your user can put the text in. Give it an ID. Render to the area tree. Use Xpath and the ID to find the block. Ask for ist height. Use this height/1000 (+ paddings, spaces, ...) to set the extent.

Betreff: Change the header/footer size in a PDF
Hi,
I have a simple XSL report with header, body and footer which renders to a PDF. My Java application passes variables to the XSL to set body-margin, header/footer-extent and font sizes.
I set the header size (in point not mm) to be slightly larger than the font size for text to appear in the header. This works fine - gives enough space for the header to hold all the text.
However, if the text in the header (which is set by a user back in the
application) is "longer" than the width of the header, that text will carry over to a next line...and so bleed into the body.
I've seen this post from a while back
http://www.nabble.com/Auto-size-header-to-fit-with-content---td4765740.html#a4765740
...but it doesn't really help. Hardcoding for line height, text height, etc, etc is too dangerous.
I've scoured the FOP Javadoc and cannot seem to figure out if it's possible to access the rendered PDF (as some sort of tree or data object) and work out if the header text has wrapped. Is it possible to determine this and so fix it?
Or is it possible to access the PDF itself and determine if wrapping has occurred in the header?
If I can detect the header has wrapped text (or footer for that matter), I can just increase the header by the original amount and re-render to PDF.
Thanks in advance,
Bernmeister.
