RE: Can't read JPEG file using JPEGReader
Ok I guess should explain, After much searching the only thing I could find to do what I want if FOP. I want to be able to read in either a gif or a jpeg and check the dimensions of it. AWT has to much overhead because it attempts to renderthe image. Whereas FOP seems just to reader the header information. As I can't guarantee that my application will run using JDK 1.4 I can't rely on JavaImage io classes. attached is a jpeg that wont read, I then went ahead and converted a working gif into a jpeg using Photoshop. It doesn't work either. If anyone has another suggestion to do what I want to do, they're mor than welcome. I know it's only using a small part of fop, and not using it for what fop was designed for, but it does work, If I can get it to read a jpeg.

No, and not with FOP for PDF, PostScript etc. As I explained just recently there is code in FopPrintServlet.java that does something like that but it applies to the AWT renderer only. Maybe you could try to change or subclass StreamRenderer.java to realize a similar effect for the other renderers. See the method processQueue().

RE: PDFRenderer.
Okay, this is good. I am picking up on what you are saying. I have done something similiar when I was building large XML documents with SAX. I had a class implement the SAX ContentHanlder. then parsed and stream all the XML files into the ContentHanlder which created one large XML file. So I need to create my SVG document. Parse it into FOP, that renders this into PDF. I think I got the basic idea. I will think some more on it and then try to put together some classes for testing.

Re: pdf file creation
No, not at the moment I'm afraid. This would probably involve adding a proprietary attribute on page-sequence that tells the PDF renderer to start a new PDF file. It may be easier to split the big PDF into smaller ones using some PDF post-processing tool. If your invoices have variable page counts you can use Driver.getFormattingResults() to obtain the number of pages for each page-sequence processed. You say it's very slow. You don't have to restart the JVM for each FOP run, do you? I hope this helps.

Re: Bug in Xalan2.4.1
This is probably without the bugfix. I was not aware of a severe problem with 2.4.1. Can you point me to a BugZilla entry? By the way, you're free to use a different version of Xalan. FOP uses the JAXP API to do XSL transformations so you're not even bound to Xalan. You may just have to adjust your classpath.

RE: PDFRenderer.
I have used PDF Transcoder for one page. It works very well. But what I am trying to do is create mulitple pages from 2D graphics. My test is to create a PDF document with three pages. For each page I create a SVG Document per page. Render the SVG document onto the PDF page. I don't know how to control the pages using the PDF transcoder. Also since this is for a print service for supporting 2 graphics, I have to be careful about space, cause the document printing could be 50 pages. Any advice ?

Re: HELP HELP HELP PERFORMANCE - there remains blocked on approximately page 100
Writing in uppercase (="Yelling") doesn't award you any plus points. Mostly it's the other way around. First of all, start by reading FOP's FAQ at: http://xml.apache.org/fop/faq.html It contains a lot of information to start from. And please consider providing more information on your problem when asking questions. You didn't even tell us if you got any error messages and if yes what they were. A few tips: - Break down you huge input file to see if there's a part in the big file that triggers the hang. - Comment out certain passages in your XSLT to narrow down the problem.

Re: How can I set the density of a pdf file in dpi?
PDFs don't have a density setting. Density is all about images. FOP currently doesn't do scaling of images. You'd have to do that externally. Have a look into the mailing list archives.

Re: fo:block coordinates
That's not so simple. Problem is that the FO elements get loaded into the FO tree. The FO tree is then transformed to the Area tree by FOP's layout engine. Only the Area tree has information on coordinates. So you would have to backtrack an Area to it FO element. What's your use case? Maybe there's another way.

Re: HELP HELP HELP PERFORMANCE !!!!
Have you tried to process your XML file with Xalan before , to know which one from Xallan or Fop crashes ?? Your .fo file may be pretty big.with a 2Mo xml file...depending of your xsl document. Xalan loads all document before processing so maybe it's a good idea to increase jvm heap Extract from Xalan website! You can also increase your jvm heap size with the -Xmx or -mx flag, depending on which JVM you are using (you can include both flags, and the JVM will ignore the one it doesn't understand). For example, to give your JVM 64 meg, try java -Xmx64m -mx64m Class Xavier Philippe PITHON a écrit: We start to publish large editions with FOP: countable listing, ledger... and render FOP explodes of everywhere!!! version FOP 0.20.5 xml size : approximately 2Mo.
