Attention! Windows's users must use LibreOffice-4.0.x built after the 28th of April. Re-export or edit DOCX file containing formulas of the 2003-format (Equation Editor 3.0), resulting in the loss of the formulas in LibreWriter-4. WinWord-2007 reveals such (re-exported) formulas as images. To repeat the error, you must: - open the file (attachment 72390 [details]), - edit any word, - to save the file, - reload this file; or: - open the file (attachment 72390 [details]), - save the formulas.docx file in ODT format, - reload the new.odt file, - save the new.odt file in DOCX format, - reload the new.docx file. I looked into the new.docx container and saw: 1. The format of formula’s images changed at WMF to EMF in the "new.docx\word\media\..". 2. There are no binaries formulas: - binary objects "new.odt\Obj100;Obj101;Obj102" is not saved as OLE-objects "new.docx\word\embeddings\oleObject1.bin;oleObject2.bin;oleObject3.bin"; - folder "new.docx\word\embeddings\..", which should contain binary objects-formulas is not in the container.
reproducible under Win7x64 using LibO 4.2.3.3 editing and saving attachment 72390 [details] all formulas are lost in that .docx except the last one. I suspect this has to do with OLE object and .docx format. maybe a duplicate of Bug 51550 ?
Created attachment 108843 [details] Original formulas in DOCX.pdf Tested with LO 4.3.3. First 3 formulas are there and they can be open. BUT, 4th formula seems like it there, at least partially, but it cannot be edited.
Created attachment 108844 [details] Formulas exported to DOCX from LO 4.3.3 (3 OK).pdf
LO 4.3.3 saved 3 formulas as OLE. In current versions LO converts all Equation OLE to Math, like explained in https://help.libreoffice.org/Common/Microsoft_Office. If saved to DOCX, it's open properly in MSO. Microsoft Word 2010 includes built-in support for writing equations to XML. Equation Editor is not used, but instead equations are edited directly from within Word. Tested with 5.0.5. I guess this one is for WFM.
