May be a lack of pdf support. I confirm the misalignement for pdf import in Draw. May be, we can have better. I set confirmed.
Sounds like Regis wanted to set to NEW, so correcting Nothing new here! Same behavior in LibreOffice 3.3.0 OOO330m19 (Build:6) tag libreoffice-3.3.0.4 Why would one expect fidelity when taking text with differing font metrics and attributes (e.g. underlining) through filter export from MS Word to PDF, import from PDF into Draw document canvas as individual text runs, and then an export to PDF from Draw? The PDF is structured with text runs drawn from spans on export, each change of font & attributes in the source OOXML or ODF will ensure it is handled in a different text run in the PDF. Then on filter import, positioning of *each* individual run as a Draw object onto document canvas is limited by our 1/100mm placement resolution. Additionally, there is also a known issue in the precision of how fonts are scaled and text glyph height and span width is calculated--which is then manifested in filter during import and export. That is why LibreOffice will *never* be considered a PDF editor--we do not hold positional precision of the objects placed to document canvas during filter import and then export, neither graphics nor text.

Indeed, the slight issue in spacing in the imported attachment 143939 [details] has improved somewhere along the way (I compare 6.0 to 24.8), and even if one can see the space is not exactly the same before and after the bold text run, we can mark as a duplicate of bug 32249. *** This bug has been marked as a duplicate of bug 32249 *** |
