Creating multi-page quicklook thumbnails

  • Does anyone know how to create multi-page quicklook thumbnails? The
    documentation only mentions API for multi-page previews, not for
    thumbnails. However it should be possible, because the system
    generators do, e.g. for PDF (as can be seen from coverflow, as well as
    the way the curled page reveals the second page). I have tried using
    QLThumbnailRequestSetImageWithData passing PDF, but that did not
    completely failed.

    There is no public API for this.  I submitted a DTS request asking
    for guidance in creating real multi-page previews, and was told there
    was no way to do it at present, and to file an enhancement request.
    I have - it's bug ID #6155052 - and it's still listed as Open in Bug
    Reporter.

  • Thanks Jon. Too bad it's private. I also added my own bug #6388051.
