Comment ajouter des commentaires à PowerPoint en Java
Aspose.Slides FOSS for Java prend en charge les commentaires en fil de discussion attachés à une diapositive à une position spécifique, visibles dans le volet Révision de PowerPoint.

</dependency>Ajouter un commentaire
Les commentaires appartiennent à un objet author. Créez d’abord un author, puis ajoutez des commentaires 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);
}Les coordonnées PointF spécifient la position de l’ancre du commentaire. Plusieurs appels à addComment() créent une chaîne de commentaires en fil sous le même auteur.
