Rendering GIF images to PDF?
Hi, I have been evaluating FOP for the past couple of weeks. Basically, I have a java wrapper program which calls the FOP libraries, which reads in an XSLT style sheet and an XML file with data, then produces PDF for each XML file read in. I have set my program to read in 1000 XML files and produce 1000 PDFs. The sole purpose of this is to get some performance timings on different operating systems/machines. One of the tests I ran consisted of producing PDFs which where 4 pages long, that contained a large table, somet text formatting, some SVG and two GIF images. Comparing this test on the Windows 2000 environment to the Windows XP environment came as a shock. The test on Windows 2000 completed in around 7 minutes, whereas on Windows XP it was closer to 20 minutes. The Windows 2000 machine has a P4 1.8Ghz CPU, 256mb RAM. The Windows XP machine much more powerful, a P4 3 Ghz, 1Gb RAM. This is why these results were disturbing. Does anyone know why GIFs take so long to render under Windows XP? My guess is, as GIF is patented, Windows 2000 seems to easily convert the GIF into another format prior to rendering (maybe using a windows tool). However, in XP, this tool may no longer be present, hence the process maybe follows another path which seems to be more expensive? I don't know, this is just a guess. Also note that under XP, the CPU usage while running this hovers around the 20% mark. I tried converting the GIFs to JPGs and the test completed in 4 minutes under XP (CPU usage was close to 100%), so I am certain the problem lies with GIFs alone. Could anyone please help me out here with some insight? Regards, Ozhan - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

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
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.

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:

{
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.

Class Transformer not found

On Fri, 2 May 2003, Jeremias Maerki wrote: Class Transformer not found simply means that JAXP is not in your classpath during compilation. You need to make sure that xml-apis.jar (which contains JAXP) is also in your classpath. I already have xml-apis.jar in my classpath. Basically, I include all the jar files from the /lib directory in my class path. Which libraries do I need to import to use the Transformer object? Is there anything else which I am missing?
