Problem rendering SVG graphic
Hi, I am new to fop (and SVG) so I hope this isn't a stupid question... I am trying to embed an external SVG graphic file into a fop document. I am simply using fo:external-graphic src=url(image.svg) when I run fop it falls over with a Java excecution trace. The first few lines look like... can somebody point me in the right direction here (I checked and batik is in the fop lib directory! ) Thanks!

Without actually running your code, I'd say it should be ok. What you can also try is to disable the stylesheet (by using the identity transformer and loading an XSL:FO file). This helps narrow down the possibilities for errors. Also temporarily comment out the SVG code in your stylesheet to see if it has something to do with that. I know that there is nothing wrong with the XSLT, including the SVG because if I run fop from the command line, passing it an XML file and the XSLT, it works fine. It only hangs when I run it via my application. I am guessing that maybe my application isn't setting a property which is needed, or something like that. If I comment out the SVG, my application runs fine. Does anyone know why this is happening? Regards.

Re: Problem rendering SVG
You didn't say whether setting the log level to LEVEL_DEBUG helped or not. Even if your XSLT is ok, my suggestions still apply. I've found bugs that way before. So if it's really the SVG that's having a problem check if Batik is in the classpath and if you're using the version that's coming with your FOP version.

Re: Problem rendering SVG
Hi, One more interesting point I should address. I have been running my application on a Solaris platform, where it has been crashing. However, I just tried running it on a Windows PC and it worked fine, didn't crash. I hope this is helpful to anyone who may know why this is.

Re: Problem rendering SVG
Ok, in this case take the examples/embedding/java/embedding/ExampleXML2PDF.java and adjust it to your usecase. Check if it works with that. I've tested it with your XSL snippet on my workstation and it worked. On 07.05.2003 08:22:58 Ozhan Hassan wrote: Sorry, I forgot to mention that.

Is that a headless server? In this case http://xml.apache.org/fop/faq.html#svg-headless may help. On 07.05.2003 08:45:32 Ozhan Hassan wrote: One more interesting point I should address.

Problem rendering SVG
Hi,
I am experiencing some a weird problem while trying to render some SVG.
I have a simple java program which reads in an XML file and an XSLT
stylesheet (containing some SVG) and render it out to PDF. What happens is
my terminal just frezzes, and I can't kill the process or do anything
else. The process only hangs when I run my application, i.e. if I run fop
from the command line passing it the XSLT with the SVG, it works fine.
Here is SVG from the XSLT style sheet:
xsl:template name=DisplaySvg
fo:instream-foreign-object
svg:svg xmlns:svg=http://www.w3.org/2000/svg;
width = 300 height=200 viewBox=0 0 300 200
xml:space=preserve
svg:g style=fill:white; stroke:#00
svg:line x1=0 y1=200 x2=0 y2=0/
svg:line x1=0 y1=200 x2=200 y2=200/
svg:rect x=10 y=150 width=20 height=50
style=fill:blue; stroke:#00/
svg:rect x=40 y=170 width=20 height=30
style=fill:black; stroke:#00/
svg:rect x=70 y=100 width=20 height=100
style=fill:green; stroke:#00/
svg:rect x=100 y=20 width=20 height=180
style=fill:yellow; stroke:#00/
svg:rect x=130 y=150 width=20 height=50
style=fill:red; stroke:#00/
/svg:g
/svg:svg
/fo:instream-foreign-object
/xsl:template

The my java application which does what I explained above is:

public static void main(String args[])
{
try
{
// only create the Transformer which reads the XSLT once
Transformer transformer = TransformerFactory.newInstance()
.newTransformer(new StreamSource(INPUT_DIR + INPUT_XSLT));
for(int i = 1; i = OUTPUT_SIZE; i++)
{
String fileName = INPUT_XML;
int fileLength = fileName.length();
fileName = fileName.substring(0, fileLength - 4);
String outFileName = OUTPUT_DIR + fileName + i + .pdf;
Driver driver = new Driver();
driver.setOutputStream(new
FileOutputStream(outFileName));
Logger logger = new
ConsoleLogger(ConsoleLogger.LEVEL_INFO);
MessageHandler.setScreenLogger(logger);
driver.setLogger(logger);
driver.setRenderer(Driver.RENDER_PDF);
transformer.transform(new
StreamSource(INPUT_DIR + INPUT_XML),
new SAXResult(driver.getContentHandler()));
System.out.println(* GENERATED PDF: + i +
*);
}
}
catch (javax.xml.transform.TransformerConfigurationException ex)
{
System.err.println(Exception: + ex.toString());
}
catch (javax.xml.transform.TransformerException ex)
{
System.err.println(Exception: + ex.toString());
}
catch (IOException ex)
{
System.err.println(IO Exception: + ex.toString());
}
// Everything is OK - exit
System.exit(0);
}
}

Any help would be appreciated.
