Comments and Notes

Darbs ar komentāriem un runas piezīmēm — Aspose.Slides FOSS for Java

Aspose.Slides FOSS for Java supports two types of annotations: vītnveida slaidu komentāri (redzams pārskatīšanas režīmā) un runātāja piezīmes (redzams Presenter View un Notes pane).

Pavedienoti komentāri

Komentāri tiek pievienoti slaidam un saistīti ar autoru. The prs.getCommentAuthors() kolekcija pārvalda visus autorus; katram autoram ir a getComments() kolekcija komentāru pievienošanai un lasīšanai.

Pievienot komentāru

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);
}

The PointF position ir collās no slaida augšējā kreisā stūra. Vairāki komentāri var tikt pievienoti tam pašam slaidam, izsaucot addComment() vēlreiz.

Vairāki autori un komentāri

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()) {
    var author1 = prs.getCommentAuthors().addAuthor("Alice Brown", "AB");
    var author2 = prs.getCommentAuthors().addAuthor("Bob Davis", "BD");

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

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

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

Lasīt komentārus no esoša faila

import org.aspose.slides.foss.Presentation;

try (Presentation prs = new Presentation("commented.pptx")) {
    for (int a = 0; a < prs.getCommentAuthors().size(); a++) {
        var author = prs.getCommentAuthors().get(a);
        System.out.println("Author: " + author.getName() + " (" + author.getInitials() + ")");
        for (int c = 0; c < author.getComments().size(); c++) {
            var comment = author.getComments().get(c);
            System.out.println("  " + comment.getText());
        }
    }
}

Runātāja piezīmes

Runātāja piezīmes tiek glabātas uz katra slaida pamata, izmantojot a NotesSlide objektu. Piekļūstiet tam caur through slide.getNotesSlideManager().

Pievienot runas piezīmes slaidam

import org.aspose.slides.foss.Presentation;
import org.aspose.slides.foss.ShapeType;
import org.aspose.slides.foss.export.SaveFormat;

try (Presentation prs = new Presentation()) {
    var slide = prs.getSlides().get(0);
    slide.getShapes().addAutoShape(ShapeType.RECTANGLE, 50, 50, 400, 200);

    // Create the notes slide and set text
    var notes = slide.getNotesSlideManager().addNotesSlide();
    notes.getNotesTextFrame().setText(
        "Mention the Q3 revenue increase on this slide. Emphasize the 24% growth."
    );

    prs.save("with-notes.pptx", SaveFormat.PPTX);
}

Vienkāršāks piezīmju piemērs

import org.aspose.slides.foss.Presentation;
import org.aspose.slides.foss.ShapeType;
import org.aspose.slides.foss.export.SaveFormat;

try (Presentation prs = new Presentation()) {
    var slide = prs.getSlides().get(0);
    slide.getShapes().addAutoShape(ShapeType.RECTANGLE, 100, 100, 500, 250)
         .addTextFrame("Main Content");

    var notes = slide.getNotesSlideManager().addNotesSlide();
    notes.getNotesTextFrame().setText("These are the speaker notes for this slide.");

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

Pārbaudiet, vai piezīmju slaids jau pastāv

getNotesSlideManager().getNotesSlide() atgriež null ja vēl nav izveidots piezīmju slaids:

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");
        }
    }
}
