RE: Building FOP (was: [PATCH] Fix DPI for PDF Transcoder.)
From: "OBRADOVIC,PETAR (HP-Vancouver,ex1)" <[EMAIL PROTECTED]> A polite request: please dont re-use existing threads to start a new thread I am sorry if I am missing something obvious but I am not able to build the latest code after this change. It seems that "batik.jar" which is checked in "xml-fop" CVS does not contain this class (SVGAbstractTranscoderUserAgent). I looked in "xml-batik" but I didn't have any luck finding this class there either. I am Ok for now by switching back to version 1.7 of "PDFTranscoder.java". I did an update just now on both Trunk and maintenance branches. After doing a "build clean" both built successfully. I assume you are referring to the trunk 1.0Dev branch as PDFTranscoder only lives in the trunk. I checked what version I built with: 1.8 which includes the latest changes. The batik.jar in the lib directory is revision 1.11 Chris _ Use MSN Messenger to send music and pics to your friends http://www.msn.co.uk/messenger

Thanks!

necessary to manually import the

Because it is an innerclass of a baseclass.

[PATCH] Fix DPI for PDF Transcoder.
Hi all,
I've attached a patch to the PDF transcoder which changes the
UserAgent to always report a pixel to millimeter conversion
corresponding to 72dpi. This is required because this is the
default userspace of the PDFGraphics2D.
It also fixes a minor issue with how the PDF graphics is setup.

dpi
Hi all, I have a question about the dpi resolution in pdf documents generated via FOP. From previous mailings I was able to extract the following information (please correct me if I'm wrong): The resolution of text depends on the output device (monitor, printer, etc.), but the resolution for gifs and jpegs is set to 72 dpi. Is there anyway to raise this value to say 150 dpi (I would like to print the document out)? One suggestion was to simply make the graphic bigger than it needs to be or to use SVG. However, I have existing graphics in gif-format which I would like to bring into my PDF-document. Does anybody have any suggestions? I would be very thankful.

the corresponding analyzer.

RE: dpi
If you're printing a background color (not graphic), the resolution of your printer is irrelevant. By the way, most printers will lay down flat color areas by mixing CMYK (or in some cases, just CMY) as dictated by your color, and interpreted through the OS and your printer software.
