I've used it with success since the perl versions (tehere has been a lyx2pdf and tex2pdf bash ones), and contributed a little (Steffen Eversand Oscar Lopez did most of the job involved in the current perl port), and yes, I have a pdf1 format associated to tex2pdf conversion :-) \format "pdf1" "pdf" "PDF (tex2pdf)" "x" "xpdf" "" \converter "latex" "pdf1" "tex2pdf $$i" "" The situations where tex2pdf gets into trouble comes mostly with latex files: use of other packages than graphicx, insertion of graphics with user-defined macros, etc. which kill the parsing for graphics names. Use with LyX seems not concerned as the latex code is clean. Another reason of failure came from unproper constructs used in \title and \author fields (used to produce pdf metadata), but again this should less happen in LyX. In addition to pdf compilation, and with the help of a configuration file (defaults are reasonable), tex2pdf provides full hyperref control, makeindex control, etc. So the command in the converter section is simple, the customization will be in the config file. Presence can be checked and the format and converter commands installed. HTH -- Jean-Pierre
