Lisää kommentti

Kommentit kuuluvat tekijä-objektiin. Luo tekijä ensin, sitten lisää kommentit kautta 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);
}

PointF-koordinaatit määrittävät kommenttikiinnityspisteen sijainnin. Useat kutsut addComment()-funktioon luovat ketjutetun kommenttiketjun saman tekijän alla.

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

    author1.getComments().addComment(
        "Initial draft: needs revision",
        slide, new PointF(1.0f, 1.0f), LocalDateTime.now()
    );
    author2.getComments().addComment(
        "Approved after changes",
        slide, new PointF(3.0f, 1.0f), LocalDateTime.now()
    );

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