    Hi,

    I don't know whether (or where) one can submit patches - but I have documents with plenty of grouped images, which do not export with current writer2latex, because for latex export the group (draw:g) element is not handled.

    As there is already a function handling groups in writer2latex/xhtml/DrawConverter.java, I simply copied that function to writer2latex/latex/DrawConverter.java, slightly modified. It outputs commented commented \begin{group} and \end{group} statements when groups are encountered, to facilitate easier changes in the latex code to, say, subfig.

    Hope some may find this useful until that part of the export fully works :)

    Hi!

    Thanks a lot for your patch!
    I will evaluate it and add support for grouped images to the next release of Writer2LaTeX.

    Best regards
    Henrik
