Hi, while debugging I found some minor problems in the produced PDF code. There is a bug in one of the /Catalog entries (/PageLayout /auto). The other problems are more of cosmetic nature (only one harmless bug). The PDF for the attached example - contains 4 totally empty and *unreferenced* dictionaries (obj 5-8) (only cosmetic) - obj 11 is questionable (but I can't read the PS function code, so maybe it makes sense somehow) (only cosmetic) - obj 20 (/JavaScript) is referring to an empty /Names dictionary; should only be added if there is JS in the document And that's all for the moment (more to come with other example) :) Best wishes, Peter This is LuaTeX, Version beta-0.42.0-2009071821 MTXrun | current version: 2009.07.20 19:44 \setupcolors[state=start] \setuppagenumber[state=stop] \pdfcompresslevel=0 \starttext \null \startMPcode fill fullcircle scaled 5cm withcolor red; \stopMPcode \stoptext
