Comments and Notes

Arbeiten mit Kommentaren und SprecherNoten — Aspose.Slides FOSS für C++

Aspose.Slides FOSS for C++ supports two types of annotations: mit Slide Kommentare (siehe in der Überprüfungsmodus) und Sprecher Noten (siehe in Presenter View und der Noten pane).

Threaded Kommentare

Kommentare sind an einen Slide angeschlossen und mit einem Autor verbunden. pres.comment_authors() Die Sammlung wird von allen Autoren verwaltet; jeder Autor hat eine comments() Sammlung für das hinzufügen und Lesen von Kommentaren.

    auto& slide = pres.slides()[0];

    // Add a comment at position (2.0, 2.0) inches from the slide top-left
    author.comments().add_comment(
        "Please review the figures on this slide",
        slide,
        PointF(2.0f, 2.0f),
        std::chrono::system_clock::now()
    );

Die PointF Position ist in Zoll vom oberen linken Ecke der Slide. Mehrere Kommentare können an die gleiche Slide hinzugefügt werden, indem Sie add_comment() wieder zu.
