Cómo agregar comentarios a PowerPoint en Python

Aspose.Slides FOSS for Python admite dos mecanismos de anotación:

Comentarios en hilo: adjuntos a una diapositiva en una posición específica, visibles en el panel de Revisión de PowerPoint
Notas del presentador: texto por diapositiva visible en la Vista del presentador y el panel de Notas

Requisitos previos

pip install aspose-slides-foss

Agregar un comentario

Los comentarios pertenecen a un objeto author. Crea un author primero, luego agrega comentarios a través de author.comments:

from aspose.slides_foss.drawing import PointF
from datetime import datetime
import aspose.slides_foss as slides
from aspose.slides_foss.export import SaveFormat

with slides.Presentation() as prs:
    # Create a comment author with name and initials
    author = prs.comment_authors.add_author("Jane Smith", "JS")

    slide = prs.slides[0]

    # Add a comment at (2.0, 2.0) inches from the slide top-left corner
    author.comments.add_comment(
        "Please review the figures on this slide",
        slide,
        PointF(2.0, 2.0),
        datetime.now(),
    )

    prs.save("commented.pptx", SaveFormat.PPTX)

Las coordenadas PointF están en pulgadas desde la esquina superior izquierda de la diapositiva. Múltiples llamadas a add_comment() crean una cadena de comentarios en hilo bajo el mismo autor.

Múltiples autores y comentarios

from aspose.slides_foss.drawing import PointF
from datetime import datetime
import aspose.slides_foss as slides
from aspose.slides_foss.export import SaveFormat

with slides.Presentation() as prs:
    author1 = prs.comment_authors.add_author("Alice Brown", "AB")
    author2 = prs.comment_authors.add_author("Bob Davis", "BD")

    slide = prs.slides[0]

    author1.comments.add_comment(
        "Initial draft: needs revision",
        slide, PointF(1.0, 1.0), datetime.now()
    )
    author2.comments.add_comment(
        "Approved after changes",
        slide, PointF(3.0, 1.0), datetime.now()
    )

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

Leer comentarios de un archivo existente

import aspose.slides_foss as slides

with slides.Presentation("commented.pptx") as prs:
    for author in prs.comment_authors:
        print(f"Author: {author.name} ({author.initials})")
        for comment in author.comments:
            print(f"  Slide {comment.slide.slide_number}: {comment.text}")

Agregar notas del orador a una diapositiva

Las notas del orador se añaden a través de slide.notes_slide_manager:

from aspose.slides_foss import ShapeType
import aspose.slides_foss as slides
from aspose.slides_foss.export import SaveFormat

with slides.Presentation() as prs:
    slide = prs.slides[0]
    slide.shapes.add_auto_shape(
        ShapeType.RECTANGLE, 50, 50, 600, 300
    ).add_text_frame("Main slide content")

    # Create the notes slide and write text
    notes = slide.notes_slide_manager.add_notes_slide()
    notes.notes_text_frame.text = (
        "Mention the Q3 revenue increase. Emphasize the 24% YoY growth."
    )

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

Agregar notas a varias diapositivas

from aspose.slides_foss import ShapeType
import aspose.slides_foss as slides
from aspose.slides_foss.export import SaveFormat

note_texts = [
    "Opening: introduce the agenda and set expectations.",
    "Key metrics: emphasize Q4 results and growth trajectory.",
    "Closing: summarize and call to action.",
]

with slides.Presentation() as prs:
    layout = prs.slides[0].layout_slide
    prs.slides.add_empty_slide(layout)
    prs.slides.add_empty_slide(layout)

    for i, slide in enumerate(prs.slides):
        slide.shapes.add_auto_shape(
            ShapeType.RECTANGLE, 50, 50, 600, 300
        ).add_text_frame(f"Slide {i + 1}")

        n = slide.notes_slide_manager.add_notes_slide()
        n.notes_text_frame.text = note_texts[i]

    prs.save("all-notes.pptx", SaveFormat.PPTX)

Verificar si ya existen notas

notes_slide_manager.notes_slide devuelve None si no se ha creado una diapositiva de notas:

import aspose.slides_foss as slides

with slides.Presentation("existing.pptx") as prs:
    for i, slide in enumerate(prs.slides):
        existing = slide.notes_slide_manager.notes_slide
        if existing:
            print(f"Slide {i + 1}: {existing.notes_text_frame.text[:60]}")
        else:
            print(f"Slide {i + 1}: no notes")
