Re: FOP memory consumption
On 2002.05.01 16:34 Bernd Brandstetter wrote: So, I have two questions/suggestions: 1) Wouldn't it be possible to let FOP create the output in two steps like for instance (La)TeX does. Doing a dry run first only to calculate the page references, store them somewhere, and then produce the actual output in a second run. As outlined on this page this is the approach that we are heading for: http://xml.apache.org/fop/design/optimise.html This should make any size document possible. 2) Are there plans to port FOP to C/C++ sometime? I guess that at least part of the memory consumption is to be blamed on Java and IIRC the underlying Xerces and Xalan are already available as C++ versions, so why not FOP? The issue of implementing FOP is not about the language. Since using java means we already have a large number of services available and reduced debugging effort then this is a logical choice (this doesn't prevent other choices). The issue is dealing with the large number of elements, properties and layout issues. Once the real problem is solved then it will be a more relevant question.
Page Sequencing to conserve memory
I'm pretty new to XSL-FO and FOP and having problems with serious memory usage on 500-1000 page docuements using tables as a reporting tool. Being that I populate the data into the page sequence from my XML data file, does anybody know of a way to end the page sequence after a screen full of data and start a new page sequence. I restrict my data in the XML to placing a screen full between FormFeed/FormFeed tags. Ideally I would like to end the page sequence when hitting a /FormFeed and start a new page sequence for an open FormFeed all within my stylesheet. Any ideas?

Re: [ERROR]: Don't know what to do with
I'm glad I'm not the only one with this problem. Interesting you noticed a problem when using it on Windows ME (i'm using that OS myself). I just found Fop 0.20.1 works exactly as expected, but Fop 0.20.3 still gives me that strange error. I'm not sure how the OS could possibly affect a java program's ability to run though. Anyway, I'd much prefer to use 0.20.3, but I'll have to use the older version too until an update is made or something is figured out. Thank you all. I'm going to poke around the Apache site now and figure out who to e-mail about the missing jimi-1.0.jar the way Windows ME affects 0.20.3.

OutOfMemory - What worked for me.
Hi guys, I had been having the memory issue over the last number of days. My fix that has worked and probably been posted before was to split up the pages of my file using a correct implementation of page sequences. Previously I had been pumping all data into one page sequence and breaking it using page breaks but FOP simply kept loading this into memory until eventually it ran out. Now I just load a page sequence at a time and this allows the garbage collector to run once all available memory has been allocated and thus free up memory used by earlier pages. As long as there is enough memory for a single page you shouldn't need much more as the collector can free this once the page has been rendered.

Re: I get a mysterious NoClassDefFoundError
Devon- Check J.Pietschmann's reply to your problem. He explains why your original command wasn't working, and why Jimi isn't included in the FOP download. I believe you can just download Jimi from the Sun site if you want it, but I've been running with the batch file as is, with no problems. It appears that if you specify a bad classpath, it's simply ignored, rather than bringing everything to a halt. -Jeff L'eau [EMAIL PROTECTED]To: [EMAIL PROTECTED] o.com cc: Subject: Re: I get a mysterious NoClassDefFoundError 05/02/2002 04:24 AM Please respond to fop-user AAhh i see. Thanx. I ignored That batch file, because it had the jimi.jar in it's path, and since that jar didn't come with my download I assumed that batch was for something totally different. Any idea where I can get a copy of the jimi.jar? I'm thinking that if I simply have that, it will solve all my problems.

Re: Memory consumption with large images in FOP
J.Pietschmann- Thanks for your help. I think I may be running out of memory when viewing the PDF. I'll do some playing around on my end, but your explanations should help a lot. Thanks again, -Jeff J.Pietschman n To: [EMAIL PROTECTED] [EMAIL PROTECTED]cc: oo.de Subject: Re: Memory consumption with large images in FOP 05/01/2002 06:00 PM Please respond to fop-user [EMAIL PROTECTED] wrote: the resulting PDF has a black rectangle, where the image should be. In PDF, images are rendered at 1/72 inch per pixel, or roughly 3.53 cm per 100 pixel. Higher resolution images are scaled down during rendering, you may see a resampling artifact, or simply a bug (probably in the PDF viewer). Be aware that the PDF viewer will have to decompress your 4k*5k pixel images at 3 bytes per pixel, resulting in allocating nearly 60 MB or more. It is also possible that you run into an arithmetic overflow or some similar problem. Is there a limit to the resolution of raster images FOP (or PDFs in general) can handle, or this perhaps a problem with memory? In theory, there is no limit, at least not directly imposed by FOP. FOP will, however, hold the file in memory, decompressed for some formats. It appears the images contained within a PDF are compressed. Does anyone know if this compression is JPEG, and if so, does FOP just dump a given JPEG into the PDF file, or does it uncompress the original JPEG in memory, and then recompress it to go into the PDF? For JPEG images, the file is dumped into the PDF basically unchanged. Finally, I haven't found a definitive list of the image types allowed in an external-graphic src attribute. Does anyone know where I might find such a list. From the sources: GIF, BMP, EPS and JPEG are supported natively, in part through standard Java mechanisms. There are not necessarily all subformats supported (BMP has at least a dozen, some very obscure, and there are a few exotic JPEG subformats as well). SVG is supported through Batik. FOP can take advantage of the Jimi image library and of JAI. Jimi is no longer distributed with FOP because of license reasons, you can get it yourself (there are instructions in the docs), but for some odd reasons it may be possible that you'll have to rebuild FOP from the sources, even though this is very easy nowadays. Jimi supports: AFP (dunno), BMP, CUR (MS Windows cursor?), GIF, ICO (Windows icons), PCX, PICT (dunno), PNG, PSD (dunno), Sun raster (used by Sun), TGA, TIFF and XBM (X Windows bitmap). JAI is an interface specification, FOP will support whatever your JAI conformant implementation supports if you drop it in (may require rebuild). This list is not authoritative, apply usual disclaimers. J.Pietschmann
RE: OutOfMemory - What worked for me.
This is great if you have logical page breaks. Only one of our reports has any logical page breaks however. So I can insert new page-sequences every 1000 rows or so. But unless I start counting rows and trying to guess at when a cell wraps, I have no way of preventing page breaks that leave awkward-looking partially filled pages.

Re: Basic-link problem in JSPs
Ralf Steppacher wrote: Are you, by any chance, using disable-output-escaping somewhere? Yes, but somewhere else in the stylesheet producing the fo document. It doesn't matter where. Do not use d-o-e if you expect your style sheet to work with short-circuit XSLT processor applications. XSLT doesn't del with tags, it uses a tree of nodes for input and output. What you think of as creating single tags is still plain text until serialization. A serialization never happens if the result is fed right into the XML consumer by using a DOM tree or a SAX event stream. Behaviour does not change if I comment out the two lines (that do not work with embedded fop either). If you delete the d-o-e stuff, dump the tree and check with the command line application, what happens? J.Pietschmann

On Win95/98/ME, the command processor feeds the whole command

the command line. Either there is a bug in the parser, or the
command processor appends some ugly invisible character. It's

the JRE doesn't count the \r as white space and passes it as
