The pdfimport was brought in from the Sun/Oracle extension. It was never intended to provide PDF editing, nor does it! So, please keep in mind that LibreOffice is not a PDF editor.
Otherwise, this is a known limitation of our pdfimport draw object filter: see tdf#101220 <https://bugs.documentfoundation.org/show_bug.cgi?id=101220> When filter imported--reading the layout and converting to native SVM objects--the embedded glyphs "subset" into a PDF receive replacement font(s) within LibreOffice. This is a practical mater as most PDF do not embed the *full* font files needed to be able to "edit" a PDF. Rather, the embedded *subset* is just those glyphs composing the PDF--again not a problem as LibreOffice is not a PDF "editor". While not using the subset glyphs is potentially a filter implementation issue--more likely it is internal to our font handling which requires Unicode based fonts--but as most PDF is generated with glyphs assigned to PUA and legacy "Adobe" code table mappings replacment font handling is necessary. Currently for PDFs that fully embed fonts, LibreOffice will not "install" those fonts. Meaning it is incumbent on the user to ensure they review the fonts composing a PDF and obtain them for use--or work with LibreOffice's font substitution dialog to assign a metric equivalent replacement. Even then there can be font naming issues--the font name extracted from PDF does not match the font name on system--so fallback occurs even though the font is present. Use of the font-replacment dialog is necessary. For high fidelity rendering of PDF, the "new" ipdf filter uses pdfium (a FOSS Google Chrome project) to render PDF to bitmap image on document canvas. That filter is evolving, to provide insertion of multi-page PDF. And, to improve the "break" action to bring improved fidelity to the resulting text strings and eventually skia based draw objects--right now it is a work in progress and font handling on break is a shambles. -- Sent from: http://document-foundation-mail-archive.969070.n3.nabble.com/Users-f1639498.html -- To unsubscribe e-mail to: users+unsubscr...@global.libreoffice.org Problems? https://www.libreoffice.org/get-help/mailing-lists/how-to-unsubscribe/ Posting guidelines + more: https://wiki.documentfoundation.org/Netiquette List archive: https://listarchives.libreoffice.org/global/users/ Privacy Policy: https://www.documentfoundation.org/privacy
