Comments and Notes

Treballant amb Comentaris i Notes del Presentador — Aspose.Slides FOSS per a .NET

Aspose.Slides FOSS for .NET supports two types of annotations: comentaris en fil de diapositiva (visible en mode de revisió) i notes del presentador (visible a la Vista del presentador i a la subfinestra de notes).

Comentaris en fil

Els comentaris s’adjunten a una diapositiva i s’associen a un autor. El prs.CommentAuthors col·lecció gestiona tots els autors; cada autor té un Comments col·lecció per afegir i llegir comentaris.

Afegeix un comentari

using Aspose.Slides.Foss;
using Aspose.Slides.Foss.Drawing;
using Aspose.Slides.Foss.Export;

using var prs = new Presentation();
// Create a comment author with initials
var author = prs.CommentAuthors.AddAuthor("Jane Smith", "JS");

var slide = prs.Slides[0];

// Add a comment at position (2.0, 2.0) inches from the slide top-left
author.Comments.AddComment(
    "Please review the figures on this slide",
    slide,
    new PointF(2.0f, 2.0f),
    DateTime.Now
);

prs.Save("commented.pptx", SaveFormat.Pptx);

El PointF la posició és en polzades des de la cantonada superior esquerra de la diapositiva. Es poden afegir diversos comentaris a la mateixa diapositiva cridant AddComment() de nou.

Múltiples autors i comentaris

var author2 = prs.CommentAuthors.AddAuthor("Bob Davis", "BD");

var slide = prs.Slides[0];

author1.Comments.AddComment("Initial draft", slide, new PointF(1.0f, 1.0f), DateTime.Now);
author2.Comments.AddComment("Approved", slide, new PointF(3.0f, 1.0f), DateTime.Now);

prs.Save("multi-author.pptx", SaveFormat.Pptx);

    foreach (var comment in author.Comments)
    {
        Console.WriteLine($"  [{comment.Slide.SlideNumber}] {comment.Text}");
    }
}

Notes del presentador

Les notes del presentador s’emmagatzemen per diapositiva mitjançant una NotesSlide objecte. Accediu-hi a través de slide.NotesSlideManager.

Afegeix notes del presentador a una diapositiva

using Aspose.Slides.Foss;
using Aspose.Slides.Foss.Export;

using var prs = new Presentation();
var slide = prs.Slides[0];
slide.Shapes.AddAutoShape(ShapeType.Rectangle, 50, 50, 400, 200);

// Create the notes slide and set text
var notes = slide.NotesSlideManager.AddNotesSlide();
notes.NotesTextFrame.Text = "Mention the Q3 revenue increase on this slide. Emphasize the 24% growth.";

prs.Save("with-notes.pptx", SaveFormat.Pptx);

Exemple de notes més senzill

using Aspose.Slides.Foss;
using Aspose.Slides.Foss.Export;

using var prs = new Presentation();
var slide = prs.Slides[0];
slide.Shapes.AddAutoShape(ShapeType.Rectangle, 100, 100, 500, 250).AddTextFrame("Main Content");

var notes = slide.NotesSlideManager.AddNotesSlide();
notes.NotesTextFrame.Text = "These are the speaker notes for this slide.";

prs.Save("notes.pptx", SaveFormat.Pptx);

Comprova si ja existeix una diapositiva de notes

NotesSlideManager.NotesSlide retorna null si encara no s’ha creat cap diapositiva de notes:

using Aspose.Slides.Foss;

using var prs = new Presentation("existing.pptx");
for (int i = 0; i < prs.Slides.Count; i++)
{
    var existingNotes = prs.Slides[i].NotesSlideManager.NotesSlide;
    if (existingNotes != null)
    {
        var text = existingNotes.NotesTextFrame.Text;
        Console.WriteLine($"Slide {i + 1} notes: {text[..Math.Min(60, text.Length)]}...");
    }
    else
    {
        Console.WriteLine($"Slide {i + 1}: no notes");
    }
}

Afegeix notes a diverses diapositives

    "Key metrics: emphasize Q4 results.",
    "Closing: call to action.",
};

using var prs = new Presentation();
// Add slides 2 and 3
var layout = prs.Slides[0].LayoutSlide;
prs.Slides.AddEmptySlide(layout);
prs.Slides.AddEmptySlide(layout);

for (int i = 0; i < prs.Slides.Count; i++)
{
    prs.Slides[i].Shapes.AddAutoShape(ShapeType.Rectangle, 50, 50, 600, 300)
        .AddTextFrame($"Slide {i + 1}");
    var n = prs.Slides[i].NotesSlideManager.AddNotesSlide();
    n.NotesTextFrame.Text = noteTexts[i];
}
