Currently the commands give a fatal error if used in different +% boxing levels: +% +% [example program above] +% +% ! pdfTeX error (ext4): \pdfendlink ended up in different nesting +% level than \pdfstartlink. +% ! ==> Fatal error occurred, no output PDF file produced! +% +% This doesn't happen very often in documents, but if the galley is +% split and reboxed it is possible that long links end in different +% levels. One example involving two column mode and top floats has +% been discussed on the latex2e github: +% https://github.com/latex3/latex2e/issues/94 +% +% Is the fatal error really sensible here? Couldn't the engines close +% the last annotation with some more or less sensible coordinate and +% continue with a warning? A pdf with a wrong link area seems better +% than no pdf at all (and would release the format and packages from +% the need to carefully keep track of boxing levels when splitting and +% reassembling stuff). +% +% [see ../16-nolink-special/*.tex for other request.] |
