drawing illustrating the issue
Libreoffice 5.3 provides the possibility to insert a PDF image in a document.
Unfortunately, the result is very inconsistent with the original PDF, showing
the same problem that arises when opening (rather than inserting) the PDF image
with LibO draw.
This is somehow expectable given that the "filter" appears to be the same,
according to http://vmiklos.hu/blog/lo-insert-pdf-image.html which states "As
you can see, the PDF import-as-graphic filter isn’t too complicated, it
completely reuses the existing "import PDF into Draw" filter, it simply copies
the first page of the resulting document model as a metafile" (regardless of
the comments in bug 104648 which states that the two are unrelated "Not at all.
They use two completely different import filters meeting different
requirements.").
IMHO this is an occasion being lost. Would have been much more useful to rely
on some PDF rendering tool (such as poppler) when "inserting" and doing the
conversion to a native metafile only when "opening" or "inserting + breaking".
This would have provided 100% fidelty on the "insert" case.
In the attachment a demo of the poor insertion. Page 1 is the PDF insertion.
Page 2 is the same PDF converted to SVG with inkscape and inserted as SVG.
