Adding support of \pdfxform to synctex
Hi there, I need some confirmation : can I assume that \pdfxform are shipped out at the very end of a regular page and that it will be the case in the future or so ? TIA
Hi Jerome, I suppose this is related to the synctex/pdfxform bug. TIA :). can I assume that \pdfxform are shipped out at the very end of a regular page I don't know. As far as I can see from a quick look at the sources, it's shipped out as a whatsit, in which case I suppose other whatsits could come after it. I don't know if \immediate\pdfxform (to ship it out in the midst of a page) does anything, or if that case matters. I hope one of the many other people on this list who knows more than me about pdftex behavior can answer you more definitively. and that it will be the case in the future or so ? Whatever the behavior is now, I do not foresee it ever changing. -k

normally one will wrap an image in a box so when boxes are synctex'd you're ok ... whatsits are officially an extension mechanism so they can be anything and normally they're ignored by the code (forms are sort of a weird exception because they have dimensions which means that in the pdftex engine there has to be explicit testing for whatsits oif that kind) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

It's not the pdfxform that matters but the reference to it, the pdflastximage etc. That node is part of the nodelist. As one doesn't really want ximage definition nodes to interfere, it makes sense to immediate those.
