Can't read JPEG file using JPEGReader
Hi there, I was wondering if anybody else has this problem. If I use either ImageReaderFactory.Make(null, inputstream) and actually give it the input stream of a file that I know is a JPEG, it return null. If I try reader = new JPEGReader() reader.verifySignature(null, new BufferedInputStream(FileInputStream)); it returns false, indicating that the input doesn't match the epected input of a JPEG File If I try the same with the GIFReader adn a GIF File, ti works fine ImageReaderFactory.Make(null, inputstream) where inputstream is that of a gif file return a GIfReader reader = new GIFReader() reader.verifiySignature(null, new BufferedInputStream(new FileInputStream(gifFile))); return true I can then procedd to get the dimensions of the image Can anyone suggest what I might be doing wrong, or a workaroudn for this problem Regards Steve - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

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 crit: 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.

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: PDFRenderer.
You just want to convert SVG to PDF? Then it's MUCH easier if you just used FOP's PDF transcoder. The transcoder is a Batik plug-in that adds PDF output support. The URL below is an example Java class I recently added to demonstrate converting SVG to PDF using the PDF transcoder. The PDF transcoder is included in Batik's current distribution (Version 1.5beta4).

pdf file creation
I'm running fop .20.5rc2 from the command line, and my xml file has over 600 invoice elements to process. This job runs very quickly, but after that I need to create a seperate pdf for each invoice. To do that, I create an xml file for each invoice and run fop on each seperately, but this is very slow due to process overhead. Is there any way to avoid this?

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. There have been several discussions and tips on this topic in the past. On 09.04.2003 08:20:42 Hans Stoessel wrote: How can I set the density in dpi for a generated pdf file?

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: 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.
Hmm, the PDF transcoder is only for one-page documents as far as I know. I wouldn't fiddle with those Area classes. Do it with XSL-FO as Jörg suggested. Try to come up with an XSL-FO or an XSL-FO generating XSLT that puts together the layout you need. This will be a lot easier than trying to make your current approach work. From what I think you do I'd do it like this: - Create an XMLReader class (see examples/embedding/java/embedding/model/ProjectTeamXMLReader) that creates a SAX stream with your SVG documents along these lines: doc svgdoc svg:svg xmlns:svg=http://.. [..] /svg:svg /svgdoc svgdoc svg:svg xmlns:svg=http://.. [..] /svg:svg /svgdoc /doc - Write an XSLT that transforms this XML format to XSL:FO with embedded fo:instream-foreign-objects. Tip: To convert a DOM to SAX events you can use org.apache.fop.tools.DocumentReader for example. Just get back again if you need more help. Good luck!

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: 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.
