Comments and Notes

Bekerja dengan Komen dan Nota Pembicara — Aspose.Slides FOSS untuk Java

Aspose.Slides FOSS for Java menyokong dua jenis anotasi: threaded slide comments (kelihatan dalam mod semakan) dan speaker notes (kelihatan dalam Presenter View dan panel Notes).

Komen Berutas

Komen dilampirkan pada satu slaid dan dikaitkan dengan seorang penulis. Koleksi prs.getCommentAuthors() mengurus semua penulis; setiap penulis mempunyai koleksi getComments() untuk menambah dan membaca komen.

Tambah Komen

import org.aspose.slides.foss.Presentation;
import org.aspose.slides.foss.drawing.PointF;
import org.aspose.slides.foss.export.SaveFormat;
import java.time.LocalDateTime;

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

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

    // Add a comment at position (2.0, 2.0) centimeters from the slide top-left
    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);
}

Kedudukan PointF berada dalam sentimeter dari sudut kiri atas slaid (disimpan secara dalaman sebagai EMU; 1 cm = 360,000 EMU). Beberapa komen boleh ditambah pada slaid yang sama dengan memanggil addComment() sekali lagi.

Nota Penceramah

Nota pembicara disimpan pada setiap slaid melalui objek NotesSlide. Akses ia melalui slide.getNotesSlideManager().

Semak Sama Ada Slaid Nota Sudah Wujud

getNotesSlideManager().getNotesSlide() mengembalikan null jika tiada slaid nota telah dibuat lagi:

import org.aspose.slides.foss.Presentation;

try (Presentation prs = new Presentation("existing.pptx")) {
    for (int i = 0; i < prs.getSlides().size(); i++) {
        var slide = prs.getSlides().get(i);
        var existingNotes = slide.getNotesSlideManager().getNotesSlide();
        if (existingNotes != null) {
            String text = existingNotes.getNotesTextFrame().getText();
            System.out.println("Slide " + (i + 1) + " notes: " + text);
        } else {
            System.out.println("Slide " + (i + 1) + ": no notes");
        }
    }
}
