Dear All, I notice that broken code for inserting movies uses node.write in codeinjections.insertmovie (in back-pdf.lua), while figures.checkers.mov (in grph-inc.lua) expects text return from codeinjections.insertmovie to feed to "texsprint(ctxcatcodes". The 3D annotation code (it also seems not to work) has node.write variant commented out and replaced with "texsprint(ctxcatcodes" with "brrrr" comment! local annot, preview, ref = backends.pdf.helpers.insert3d { ...... } -- node.write(pdfannotation(width,-height,0,annot())) texsprint(ctxcatcodes,format("\\pdfannot width %ssp height %ssp {%s}",width,height,annot())) -- brrrr --~ if ref then -- wrong ! a direct ref should work --~ texsprint(ctxcatcodes,format("\\smash{\\pdfrefximage%s\\relax}",ref)) -- brrrr --~ end texsprint(ctxcatcodes,"\\stopfoundexternalfigure") And the question is: does it make sense to try to make the current 3D annotation handling code work by complaining to the maintainers and/or fixing it myself or nothing is supposed to work till migration to from "texsprint(ctxcatcodes" API to "node.write" API is complete? Sincerely, Michail
