Manage modern slide comments in Aspose.Slides for Python via Java: add, read, remove, and reply to comments in PowerPoint and OpenDocument presentations.

This article demonstrates how to add, read, remove, and reply to modern comments using Aspose.Slides for Python via Java.

Install the package as described in Installation. Each example imports asposeslides before starting the JVM, then imports the API and required Java types after the JVM is running. The access and removal examples use modern_comment.pptx, created by the first example.

Add a Modern Comment

Create a comment authored by a user and save the presentation.

import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import Presentation, SaveFormat
from java.awt.geom import Point2D
from java.util import Date

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)
    author = presentation.getCommentAuthors().addAuthor("User", "U1")
    position = Point2D.Float(100, 100)
    author.getComments().addModernComment("This is a modern comment", slide, None, position, Date())

    presentation.save("modern_comment.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()

Access a Modern Comment

Read the first modern comment from an existing presentation.

import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import Presentation

presentation = Presentation("modern_comment.pptx")
try:
    if presentation.getCommentAuthors().size() > 0:
        author = presentation.getCommentAuthors().get_Item(0)
        if author.getComments().size() > 0:
            comment = author.getComments().get_Item(0)
            print("Author:", author.getName())
            print("Comment:", comment.getText())
            print("Position:", comment.getPosition())
        else:
            print("The first author has no comments.")
    else:
        print("The presentation has no comment authors.")
finally:
    presentation.dispose()

Remove a Modern Comment

Remove the first comment and save the updated presentation.

import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import Presentation, SaveFormat

presentation = Presentation("modern_comment.pptx")
try:
    if presentation.getCommentAuthors().size() > 0:
        author = presentation.getCommentAuthors().get_Item(0)
        if author.getComments().size() > 0:
            comment = author.getComments().get_Item(0)
            comment.remove()
        else:
            print("The first author has no comments.")
    else:
        print("The presentation has no comment authors.")

    presentation.save("modern_comment_removed.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()

Reply to a Modern Comment

Create a parent comment, add two replies, and save the presentation.

import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import Presentation, SaveFormat
from java.awt.geom import Point2D
from java.util import Date

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)
    author = presentation.getCommentAuthors().addAuthor("User", "U1")
    created_time = Date()

    parent_position = Point2D.Float(100, 100)
    parent_comment = author.getComments().addModernComment("Parent comment", slide, None, parent_position, created_time)

    reply1_position = Point2D.Float(110, 100)
    reply1 = author.getComments().addModernComment("Reply 1", slide, None, reply1_position, created_time)

    reply2_position = Point2D.Float(120, 100)
    reply2 = author.getComments().addModernComment("Reply 2", slide, None, reply2_position, created_time)

    reply1.setParentComment(parent_comment)
    reply2.setParentComment(parent_comment)

    presentation.save("modern_comment_replies.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()
