Embedded EPS in PDF
Hello fop-users, I have a problem if I insert a eps file in a pdf document (as external-graphic). This graphic will be inserted and Acrobat Reader naturally ignores the postscript content inside the pdf, also a postcript printer prints this document correctly, because its interpreter ignores the binary preview data. If I try to redistill this pdf file using ghostscript (to make the postscript content visible), gs complaints about this preview content and stops the rendering. A first look at the EPSReader class #verifySignature shows me that there is a correct check for binary header (0xC5D0D3C6), but the incoming streambuffer always starts with 0x37338083 (%!PS). That would be wonderful for, but it seems to be, that in the pdf, the original data (inclusive preview) is inserted ;( Has anyone an idea where I have to look, to eleminate this (bug)? -- Best regards, Torsten mailto:[EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Including images from a servlet
Hi, I'm using FOP with a servlet. The servlet generates XML which is then translated using XSL or, if the user clicks print, will take the XML and generate a PDF. In the XSL-FO I have an image that appears in the produced PDF and reference it like so: fo:external-graphic src=url(logo.jpg)/ if I do it this way though then the image is searched for in the current directory, usually the Web Server's bin directory, so I usually have to write it like so: fo:external-graphic src=url(path/to/file/logo.jpg)/ is there a way to make it search for the image in the current directory, i.e. the same one as the XSL-FO stylesheet?

You can set the base directory for which relative paths will be resolved against. This can be done using a configuration file, or set in a program.

Embeded EPS in PDF
Hello fop-user, Forget the previous mail ;) I've redirected a stream into a file and see the prob now. We don't send the eps-file to fop, but we create an 'real' postscript file which has the eps included (plus some extra listing informations). Now EPSReader only checks the first 4 byte for an binary preview header, but this header can be located at any place in the 'ps' file (one header for each included eps with preview). I don't know, whether this is conform to the postscript specification. If yes, it is necessary to scan the whole file for possibly embedded eps file(s) and to skip ALL! preview data and binary headers of all included eps files. Does anyone know, whether this is a bug (I can fix it and send a patch), or not rule conform from our side, then I remove the preview before inserting it in the postscript.

RE: Including images from a servlet
URL : unknown protocol: c
Well, 'c' is not a protocol, you should try something like :
file:C:///stylesheets/fop
or
url('file:C:///stylesheets/fop')
I'm no sure, experts will tell you more

I don't know, whether this is conform to the postscript specification. You can check yourself: http://partners.adobe.com/asn/tech/ps/technotes.jsp Look for: Encapsulated PostScript (EPS) File Format Specification Version 3.0 #5002 5/1/92 (PDF: 182 KB / 34 pages) My interpretation of the EPS specs is indeed so that all parts (EPS or preview) can be located at any place. That's what the indices and section sizes are for. But this applies to device-specific screen previews only. There are also device-independent screen previews that work with DSC comments which are, however, not supported by the EPSReader ATM. If yes, it is necessary to scan the whole file for possibly embedded eps file(s) and to skip ALL! preview data and binary headers of all included eps files. Are you talking about multi-page EPS files perhaps? I don't think there may be multiple binary headers as described in chapter 5 of the EPS 3.0 specs. Maybe you could post (or provide a link to) one of your EPS files so I can see what kind of EPS file you're talking about. I understand there are quite a few flavours. Does anyone know, whether this is a bug (I can fix it and send a patch), or not rule conform from our side, then I remove the preview before inserting it in the postscript. As indicated above I can't tell right now if it's a bug. We are certainly eager to get any patches with improvements for FOP. Simply keep in mind that if you patch FOP 0.20.5 or the maintenance branch from CVS your patch will most likely not make it into the codebase as the development focus is clearly on HEAD. Patches for HEAD are highly welcome however. But I guess you know that already. We keep talking about that all the time and it gets boring. :-) Jeremias Maerki - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
NullPointer in setupDefaultMappings in embedded FOP
I'm writing a Java application which uses embedded FOP to convert XML
to PDF. My code is based on ExampleXML2PDF (which does the XSLT
transformation internally), and I'm running FOP 0.20.5 under Java
1.4.1 on a MacOS X machine.
I get the following error:
Exception in thread main java.lang.NullPointerException
at org.apache.fop.apps.Service.providers(Driver.java:597)
at org.apache.fop.apps.Driver.setupDefaultMappings(Driver.java:319)
at org.apache.fop.apps.Driver.init(Driver.java:222)
at the point at which my code calls 'driver.setOutputStream'. Here
are some data points:
1. The XSLT stylesheet is good; using the FOP Ant task to apply
it to the input XML document produces the correct PDF output.
2. The transformation is working correctly within the application;
redirecting the output from the transform to a StreamResult
(rather than the SAXResult used to drive FOP) produces a '.fo'
document which is identical to the one produced by the Ant
Style task, and which can then be fed to Ant FOP without
problems.
3. The application is able to read the required input files and
write the required output files: no permissions or missing
directory problems.
Any suggestions as to the possible cause of this problem, and fixes
or workarounds would be very welcome. The relevant piece of my code
is shown below.
Thanks in advance,
Angus
Driver driver = new Driver();
driver.setRenderer(Driver.RENDER_PDF);
File outpath = new File(targetdirectory,getOutputFilename(file));
File tmppath = new File(targetdirectory,getTemporaryFilename(file));
try {
driver.setOutputStream(new java.io.FileOutputStream(tmppath));
Transformer transformer = compiledstylesheet.newTransformer();
transformer.transform(new StreamSource(file),
new SAXResult(driver.getContentHandler()));
}
catch (Exception e) { }
