In pdftex "if the \pdfpageattr value contains the string /MediaBox, then pdfTEX omits outputting its own /MediaBox value". That means that the following produce a PDF with only one /MediaBox in the page dictionary:
\pdfcompresslevel0 \pdfobjcompresslevel0 \pdfpageattr{/MediaBox [0 0 200 300]} abc \bye
The same is not true for luatex:
\pdfvariable compresslevel = 0 \pdfvariable objcompresslevel = 0 \pdfvariable pageattr{/MediaBox [0 0 200 300]} abc
\bye
leads to two entries (using pdf.setpageattributes gives the same):
/MediaBox [ 0 0 595.276 841.89 ] /MediaBox [0 0 200 300]
Would it be possible to copy the pdftex behaviour also in luatex?
(sorry for the delay...) Hans and I are talking about it, parsing here is a bit fragile thing . -- luigi
