Re: Out of Memory problem
Thanks Chris, Would appreciate ifu can explain more how shall i increase memory in my case - I am on Tomcat server andusing servlet to render the fop. I am not using fop.bat file, Which script starts my JVM - really speaking i also do not know. My servlet.jar / fop.jar and related files are inside /WEB-INF/lib directory. I am compiling all files thr ant (all class path is set in CLASSPATH) How can i increase memoryso as to get correct font and pdf in my case? regards Manisha Chris Bowditch [EMAIL PROTECTED] wrote: Manisha Sathe wrote: I am trying for one Chinese PDF.

Once i use this font then i get this error (even if it is just 2-3 pages long - sometimes at very beginning i get the 1 page report - after that even not that) I tried the the things mentined such as reduce the size of image, page sequence (do not know how to increase the JVM memory on fly) - also reset the Cache etc what ever given in docs, but still same.To increase JVM memory, just change your FOP.bat or whatever script starts your Java VM and specify command line parameter -Xmx256M. The default is 64Mb, which isnt sufficient due to the large number of glyphs in The Arial Unicode font.Chris-To unsubscribe, e-mail: [EMAIL PROTECTED]For additional commands, e-mail: [EMAIL PROTECTED]__Do You Yahoo!?Tired of spam?

RE: RE : Contributing to FOP (Re: representative example needed)
Hi there, Sorry, My goal is to post these files, however there are some work I have to do on them in order to make them look nice and clean, I really want to do that before anyone looks at them, to really get them representative, but I have had a lot of other work lately, so I havent been able to finish them up yet. For us it has really been what the transform produces that was critical. I never took the time to develop nice and efficient XSLT transforms. One example is the graphs in those PDFs, I generate those graphs with an intermediate tool that I wrote which generates SVG graphs from data and layout input in XML format. This SVG graphs is first generated as separate files, then copied into the final FO document at FO compile time, using XSLT document() function. This is a rather odd approach which I do not know how I can best present to the FOP users/developers who might be interested in seeing the solution, I am therefore thinking of moving these solutions to EXSLT instead, and use _javascript_ to compute layout and render the graph to SVG. XSLT itself is unfortunately not enough to generate these graphs. I was glad to see there where actually FOP people that was a bit interested in the work I have done with FOP, now i do not want to disappoint people by sending these XSLT transforms that is just not clean enough as of today.

Performace Barcode4j
Hi, Recently,I explored barcode4j and was successful to render barcode using that with all ur help.We suspended that project for a while and now we are into it again. Just to recap, we were using IDAutomation fonts to render barcode(EAN8) in our application,but we found it has some limitations like font strectch so we tried barcode4j and it worked great. So we want to explore abt performance as we have decided to go ahead with that, If iam not wrong,barcode4j creates an image(SVG) to render the barcode in the PDF we have noticed that it is taking more time to render the image when compared toIDAutomation fonts. is this the expected behaviour? appreciate your ideas, Thanks Jeremias Maerki [EMAIL PROTECTED] wrote: On 15.12.2004 12:11:39 kumar Bandaru wrote: Wow Wow Wow! I got the barcodes rendered.Thanks for your suggestions.I started all over again .it worked.Good to hear. :-) As Barcode4J doesn't need Fonts to render the barcode, The only way to increase the barcode size is using the and barcode:module-width ? Iam i right abt this??Yes. What are the defaults barcode4j uses for height and width ??That depends on the symbology in use. Have a look at the following linkwhere you can see the defaults for EAN-8 barcodes:http://barcode4j.krysalis.org/barcode-xml.html#EAN-8 How can i align the barcode within the cell?

Re: Performace Barcode4j
Yes, this is expected behaviour. The path from SVG via Batik to PDF is suboptimal if speed is an important issue. The SVG generation itself is very fast, but the conversion from SVG to PDF isn't. In the case of PostScript output I have a non-standard solution (i.e. doesn't work with an unmodified FOP 0.20.5) to directly embed the barcode as EPS in the generated PostScript stream. The same I have started for PDF but only the painting of the bars is implemented. No human-readable part. If performance is your biggest concern you need to resort to a barcode font. There's no faster solution at the moment.

Font and image problem
Hi, I have a strange problem.I have set some custom fonts in the userconfig.xml . In my java code I am using the org.apache.fop.configuration.Configuration.put(baseDir ,baseDir); code to set my base dir. The problem is the fonts are picked correctly but if there is any image in the xml source the transformer is not able to pick it since the above code changes the context path . Does any one have encountered similar problem ? Please help me in resolving this issue. I need both custom fonts and image .
