RE: png vs. jpg
Hi Luis, I went to the page you provided (ImageLoaderRawPNG) and noticed in the config for application/pdf I searched for xmlhandler and cannot find any reference to this tag (other than the page you gave). I'm generating PDFs using embedded FOP (which include a small SVG image). As a test, I generated a PDF with the tag in the FOP config and then without and I noticed no (obvious) difference in timing/memory. Is this tag necessary...what does it do? Thanks in advance,Bernard. Date: Wed, 16 Oct 2013 23:44:52 +0100 From: lmpmberna...@gmail.com To: fop-users@xmlgraphics.apache.org Subject: Re: png vs. jpg Yes, there is a difference. By default FOP uses a "native" image loader for JPG but not for PNG. There is however a native image loader for PNG too, which you can enable in the configuration file. See http://wiki.apache.org/xmlgraphics-fop/HowTo/ImageLoaderRawPNG for more info. Try it and I expect that you will see a performance improvement.

RE: Memory usage and page numbering...
Having now done a few runs using JVM Monitor on both Ubuntu 32 bit and 64 bit, I've found that the heap memory is slightly less when page numbers with totals are used compared to no page numbers at all.

Date: Fri, 9 Aug 2013 15:20:15 +1000 Hi, I have a Java desktop application, using embedded FOP to create PDFs from a data XML file and an XSLT file. I wanted to see how much memory is being used, given the point about memory usage, page numbers and page totals (http://xmlgraphics.apache.org/fop/1.1/running.html#memory). My PDF reports have a "page N of TOTAL" at the bottom right of each page and I wanted to see the memory usage and compare to no page numbers and just page numbers without totals. I also used the two variations for page number totals (XSL 1.0 and XSL 1.1). To work out the memory usage I computed the difference when calling Runtime.getRuntime().freeMemory() at the start and end of the render process. I ran each render variation 5 times from a shell script and each render kicked off a separate JVM to avoid any caching. Regardless of whether I had page numbers or not, and page totals or not, it seemed the result is that there is no difference between having page numbers/totals or not. Sometimes the memory usage was 50 MB and sometimes 200 MB. I then used the sample code and data files from embedded FOP, http://svn.apache.org/viewvc/xmlgraphics/fop/tags/fop-1_1/examples/embedding/. I modified the data XML file to contain lots of entries, giving a data file size of about 1 MB. I also modified the XLST file to include pages numbers and then also page totals. Again, I noticed no difference in memory usage. Given the varying values for memory usage I'm seeing, I assume my quick and dirty method is inadequate. I expected variation, but mostly to see far less memory usage when no page totals were used, but that's not the case. Has anyone seen similar results? Does using page totals really use THAT much more memory compared to not using page totals? Thanks in advance,Bernard.

RE: Getting a list of font names without the memory hit...
Thanks Chris - simplest solution is often the best: String fonts[] = GraphicsEnvironment.getLocalGraphicsEnvironment().getAvailableFontFamilyNames(); Getting a list of fonts this way does NOT appear to impact memory at all...so much better! I don't have the tag in my config file, so I assume the cache is on by default. I did a test run of creating a PDF: With no present: memory used 111 MBWith false present: memory used 330 MB I think I'll stick with the default!

RE: Getting a list of font names without the memory hit...
I've done some more digging/testing and noticed that when I get the fonts
map...
FontInfo fontInfo = new FontInfo();configurator.setupFontInfo( documentHandler,
fontInfo );Map fonts = fontInfo.getFonts();
(the above essentially comes straight out of listfonts() and its subcalls)
the fontInfo.getFonts() was returning a Collections.unmodifiableMap(this.fonts)
which I initially thought was the memory hog. Well it sort of is, but it is
not the main culprit.
Noticing that this.fonts is private, I used reflection to access the this.fonts
directly (so no copy took place) and still the memory was excessive
(essentially little difference to what I've initially seen).
On digging deeper, the big memory hit is happening within
configurator.setupFontInfo( documentHandler, fontInfo );.
Let me back up and ask a couple of sanity questions...first, to reiterate: my
desktop Java application allows a user to create PDF reports (from XML and XSL)
by making direct Java calls to FOP (that is, I do NOT invoke FOP from the
command line).
1) I want the user to be able to choose the name of a font for a given report.
Should I be getting the font names by calling FontListGenerator.listFonts()?
2) I noticed in the guts of configurator.setupFontInfo(), there is a font
cache file which is written. Is it possible to get the fonts names from this
file instead?
In short, I am not fussed on how I get the font names so long as the memory
doesn't go through the roof!

really I can't be sure as I don't fully follow what's going on!
Ideally I'd just up the amount of memory supplied to the desktop application,
but I don't have that option and besides, it just delays the problem of running
out of memory.
Thanks in advance,Bernard.
RE: Still having trouble loading fonts at runtime - suggestions?
Hi Phill, I make a call to FOP itself to find the fonts - see FOPManager::InitialiseFonts in the code from my first reply. The magic line is SortedMap fontFamilies = new FontListGenerator().listFonts( ms_fopFactory, org.apache.xmlgraphics.util.MimeConstants.MIME_PDF, fontEventListener ); I've looked at the FOP internal code and they simply squirrel through various directories, based on the current OS, to find font files. I call this code and then simply cache that information. I suspect to add a font in at runtime you'd need to configure that in the FOP configuration file - never had to do this myself.

RE: Still having trouble loading fonts at runtime - suggestions?
Hi Phill, The PropertiesManager is a class of mine which basically extends java.util.Properties and essentially reads/writes a hash table of key/value pairs. I store in the properties a list of the font names and their respective font files (as discovered via FOP). For me on Ubuntu 12.04 I get: FontList=Andale Mono,Arial,Arial Black,Bitstream Charter,Century Schoolbook L,Comic Sans MS,Courier,...FontFiles=file\:/usr/share/fonts/truetype/openoffice/opens___.ttf,file\:/usr/share/fonts/truetype/ttf-khmeros-core/KhmerOS.ttf,... I cannot remember precisely why I had to implement this "cache" but I think it had to do with supporting i18n. Originally I simply used the hard coded default fonts which FOP "provided" but I found on some non-English machines I'd get the 'square' symbol and so wanted to provide a way for a user to specify a font to use for the render. To do this I got FOP to tell me what fonts were available and present that to the user. I just cache that information so I don't have to ask FOP each time (which can take a few minutes). When I do the render I pass the font name as one of the transformer parameters: xslParams.put( "font-family", (String)m_fontName.getSelectedItem() ); where m_fontName is the selected font name in the JComboBox shown to the user.

RE: Still having trouble loading fonts at runtime - suggestions?
Hi Phillip,
I have written a desktop application which, on start up, refreshes a cache of
fonts (using FOP code) and subsequently allows the user to refresh that cache
by hitting a button (again, calls the same FOP code).
See attached.
When the application starts up I call FOPManager.refreshFonts( false );
Before allowing the user to initiate a print, I call FOPManager.isReady()
When the user forces a cache update, I call FOPManager.refreshFonts( true );
My fopConfiguration.xml is standard and doesn't do anything fancy.
Cheers,
Bernard.

Interrupt/cancel/abort a render
Hi, I'm wondering if it's possible to interrupt/cancel/abort a render once it has been started. I'm embedding FOP into a Java desktop application in a similar way which is described here: http://svn.apache.org/viewvc/xmlgraphics/fop/trunk/examples/embedding/java/embedding/ExampleXML2PDF.java?view=markup. I've looked at the API and nothing is immediately obvious. I found this old forum post (http://www.mail-archive.com/fop-user@xml.apache.org/msg05146.html) which didn't help. I am running the rendering process in a thread but not sure how I'd go about cleanly/gracefully aborting a render. Thanks, Bernard.
RE: fop not handling svn rotated text on linux
Something which happened to me (unrelated to rotating text) but I noticed a difference between the PDF viewing engines of Adobe and Ubuntu's Document Viewer. There is some bug in the way the underlying library (used by Document Viewer) does rendering - I cannot remember the specifics but the bug was there still a few months ago. So perhaps look at your PDF using Adobe PDF viewer on Linux? > Date: Fri, 24 Jun 2011 17:08:20 -0600 > From: rsarg...@xmission.com > To: fop-users@xmlgraphics.apache.org > Subject: fop not handling svn rotated text on linux > > Using fop-0.95 in this case.

Missing render messages
Hi, Having trouble capturing all logging from a FOP render. I am using log4j and have configured it using the XML file (see the end of this post). Normally I find that all logging goes to my log file and console as per the logging level I set. However I found by accident I had mistyped an attribute in an XSL file: instead of I had I noticed on the console after doing a render (in Eclipse) the following messages (the first two were in red): [Fatal Error] pagesetup.xsl:6:16: Attribute name "n" associated with an element type "xsl:param" must be followed by the ' = ' character. file:/home/bernard/reports/pagesetup.xsl; Line #6; Column #16; org.xml.sax.SAXParseException: Attribute name "n" associated with an element type "xsl:param" must be followed by the ' = ' character. 2011-05-07 14:11:08,228 [Thread-1] PrintToPDF - PrintToPDF$PrintToPDFUsingFOP.run(PrintToPDF.java:2025) - java.lang.NullPointerException However in my log file only the third error (the exception) was present. The first two lines were NOT in the log file. My log4j configuration file is below. I've tried specifying different classes to get different levels and to coax out the error message. Even trying with all logging set to 'all' does not show the first two error messages. Any ideas on how to capture all the information from the render? http://jakarta.apache.org/log4j/";> Thanks in advance, Bernard.
Inclusing of a dynmaically generated SVG into XSL
Hi, I have a dynamically generated SVG image (using Batik included with the FOP distribution) and I want to pass the SVG (say as a bytearrayoutputstream) into the render process. The render process is typical: bufferedOutputStream = new BufferedOutputStream( new FileOutputStream( outputPDFFile ) ); fop = fopFactory.newFop( org.apache.xmlgraphics.util.MimeConstants.MIME_PDF, foUserAgent, bufferedOutputStream ); transformer = TransformerFactory.newInstance().newTransformer( new StreamSource( xslStylesheet ) ); source = new StreamSource( xmlData ); result = new SAXResult( fop.getDefaultHandler() ); transformer.transform( source, result ); I've found the following two articles which have given me a bit of an idea: http://old.nabble.com/How-to-transform-embedded-FO--td31231565.html http://old.nabble.com/Embedding-SVG-dynamically-into-fo-file-td30691616.html but I can't seem to figure out once I have my SVG as a bytearraystream what to do with it: SAXSource saxSource = new SAXSource( new InputSource( new ByteArrayInputStream( byteArrayOutputStream.toByteArray() ) ) ); Where do I put the saxSource? At the other end, what tag/block do I use in the XSL file to place the SVG? Currently I pull in an SVG file using the tag which is fine for the file version...but not sure what to do for a dynamically generated version. >From what I've read it should be possible to create an SVG on the fly and pass >it into the render process...just can't join all the dots! Thanks in advance, Bernard.
Minimising FOP footprint...
Hi, I've noticed there's a lot of 3rd party JAR files bundled with FOP 1.0, notably: avalon-framework-4.2.0.jar batik-all-1.7.jar commons-io-1.3.1.jar commons-logging-1.0.4.jar serializer-2.7.0.jar xalan-2.7.0.jar xercesImpl-2.7.1.jar xml-apis-1.3.04.jar xml-apis-ext-1.3.04.jar xmlgraphics-commons-1.3.1.jar and was wondering how many do I actually need? If "all I'm doing" is using FOP to render an XML file using XSL template to a PDF, is there a way to trim out the unwanted JARs? I can do a clean compile of my application, minus the JARs above listed in the classpath. If I can the run my application and exercise the FOP part of it, does that tell me which JARs I can drop or am I being too naive? On a somewhat related note, in doing an ANT build and setting the compiler args as follows: I get a few path warnings: [javac] warning: [path] bad path element "/lib/fop-hyph.jar": no such file or directory [javac] warning: [path] bad path element "/lib/xml-apis.jar": no such file or directory [javac] warning: [path] bad path element "/lib/xercesImpl.jar": no such file or directory [javac] warning: [path] bad path element "/lib/serializer.jar": no such file or directory [javac] warning: [path] bad path element "/lib/log4j.jar": no such file or directory So are these old manifest entries that have not been updated to the new versions? Can I safely remove these from the mainfests in the FOP JAR files? Thanks, Bernard. _ Browse profiles for FREE! Meet local singles online. http://clk.atdmt.com/NMN/go/150855801/direct/01/
RE: Referring to a image file in a JAR file
Thanks to all...managed to sort it out!
For future reference:

2) The XSL I used to refer to my image (in the same jar file as the Java code,

RE: Referring to a image file in a JAR file
I already have a URIResolver implemented to resolve the something such as
which is what the Javadoc says it's used for:
http://download.oracle.com/docs/cd/E17409_01/javase/6/docs/api/javax/xml/transform/URIResolver.html
Unfortunately, the does not trigger the call to my URI
resolver. I have tried src=url() etc with no luck. So either I've got the
wrong format of the URL or it cannot be done this way.
I don't see how to use xls:include, xsl:import and document (as per the
Javadoc) to refer to the graphic file. In your example, did you refer to
images using fo:external-graphic or using some other tag?
The other thing I noticed is I set my URIResolver on the TransformerFactory:
SAXTransformerFactory saxTransformerFactory =
(SAXTransformerFactory)TransformerFactory.newInstance();
saxTransformerFactory.setURIResolver( myURIResolver );
instead of on the foUserAgent which you did...so dunno if that makes a
difference.
