Voeg een reactie toe

Opmerkingen behoren tot een author‑object. Maak eerst een author aan, en voeg vervolgens opmerkingen toe via author.getComments():

import org.aspose.slides.foss.Presentation;
import org.aspose.slides.foss.ISlide;
import org.aspose.slides.foss.ICommentAuthor;
import org.aspose.slides.foss.ICommentCollection;
import org.aspose.slides.foss.IComment;
import org.aspose.slides.foss.export.SaveFormat;
import org.aspose.slides.foss.drawing.PointF;
import java.time.LocalDateTime;

try (Presentation prs = new Presentation()) {
    // Create a comment author with name and initials
    ICommentAuthor author = prs.getCommentAuthors().addAuthor("Jane Smith", "JS");

    ISlide slide = prs.getSlides().get(0);

    // Add a comment at position (2.0, 2.0) from the slide top-left corner
    author.getComments().addComment(
        "Please review the figures on this slide",
        slide,
        new PointF(2.0f, 2.0f),
        LocalDateTime.now()
    );

    prs.save("commented.pptx", SaveFormat.PPTX);
}

De PointF coördinaten specificeren de positie van het anker van de opmerking. Meerdere aanroepen van addComment() creëren een gestructureerde commentaarketen onder dezelfde auteur.

        slide, new PointF(1.0f, 1.0f), LocalDateTime.now()

    );

    prs.save("multi-author.pptx", SaveFormat.PPTX);
}
