Impress related part is in +sd/source/filter/eppt/pptx-* and the other part is in +oox/source/export/ because it contains mostly code related to +DrawingML, which is shared with writer and calc ooxml export. + +The export filter was written in 2009 IIRC and was not much extended +feature-wise lately. + +FUTURE work: add custom shapes export (see below). enhance text +output, we don't write text style for indentation levels now, need to +export a:lvl1pPr, a:lvl2pPr, ... elements. + +PPTX import was written by Sun/Oracle and then extended in LibreOffice +a lot during bug fixing. It is located in oox/source/ppt and +oox/source/drawingml. The areas with most bugs (at least until today) +were shape placeholders and text style inheritance. |
