One user reported a crash when using this tool with a custom letterhead class; the class in question may be found at http://www.soe.ucsc.edu/~elm/LaTeX/ucletter.cls (though note that a simpler demonstration is attached to this report). The bug is triggered by the fact that this class loads an image during the processing of the preamble (i.e. during the processing of the .ini file) and saves it in a box. When this box is used, during the compilation of the body, pdftex crashes. This does work with ordinary (non-PDF) TeX, so the problem is specific to PDFTeX. The attachment contains a simple demonstration of the problem. Unpack it and run 'make'. ---------------------------------------------------------------------- Comment By: Reinhard Kotucha (reinhard) Date: 2007-06-26 01:26 Message: Logged In: YES user_id=4195 Martin, you probably can't do everything in a format file. However, it would be nice to be able to put graphics to a format file at least. Suppose that a web server has to generate PDF files on-the-fly, each contains a company logo. The best place place for the logo is the format file if speed matters. It would be nice if there are no restrictions.

Thanks. If you replace the PDF image by an EPS file, and use -output-format dvi, then it does work. That suggests to me that the problem is not fundamentally caused by a limitation of IniTeX. But I don't know enough about the inner workings of the \includegraphics command to be sure about that. (Perhaps PDF graphics are handled in a sufficiently different way for this to be a false comparison?) In any case, as you say, it shouldn't crash! ---------------------------------------------------------------------- Comment By: Martin Schröder (oneiros) Date: 2007-06-26 00:30 Message: Logged In: YES user_id=421 I can reproduce it, and it obviously shouldn't crash, but I'm really not shure if it's supposed to work, as the format of course will not save the picture. You can't do everything in IniTeX... ---------------------------------------------------------------------- You can respond by visiting: http://sarovar.org/tracker/?func=detail&atid=493&aid=824&group_id=106
