It's roughly tested: The manual still compiles.

But samplepdf doesn't compile.

Runaway argument? ! Paragraph ended before \handleMPsequence was complete. <to be read again> \par l.2

I haven't touch this part at all. Has anybody?

(1) maybe clean-up old mpgraph.* files (2) maybe your format uses an old supp-pdf (somewhere else in the three) with a new context there has been a change (in metafun) with regards to the amount of special things (jump from 1K to 10K) but this is (if i'm right) made in an upward compatible way Hans

ok, now it seems that \pdfobj{Hello} does not create a legal PDF object, as it's none of the eight types described in the PDF Reference section 3.2. E. g., a cross check shows that \pdfobj{false} is ok, a boolean value, while \pdfobj{maybe} does not work :-) Regards, Hartmut

Hi, Hartmut Henkel wrote:

thanks for testing. Seems to be in the pdflastlink change file, somehow related to the replacement of

obj_annot_ptr(obj_ptr) := p;

I think I've found the cause of the problem, and it is not the change file itself; that just drew another bug to the surface. It turns out that when copying node lists, the sixth field of an annot whatsit was never copied, and that's field that is used to store the object number for \pdflastlink and \pdflastannot. Hence the copied one was never properly initialized. I've attached a new version of pdflastlink.ch that has three changes compared to the one by Ralf: * The quoted bits of web are a bit larger, so it reads a bit easier * I've added a section of the @, to copy the pdf_link_objnum() field * There was no need for pdf_create_obj() in do_link any more.
