Comments and replies Leave feedback
On this page
Every annotation can carry a discussion thread. You build the thread as a list of Reply objects and assign it to the annotation’s replies property. Each reply has a comment and a User, and each user has a name and a Role (Role.EDITOR or Role.VIEWER).
The example below creates an area annotation and attaches a two-message conversation between two users before saving the document.
from groupdocs.annotation import Annotator
from groupdocs.annotation.models import Rectangle, Reply, User, Role
from groupdocs.annotation.models.annotation_models import AreaAnnotation
from groupdocs.pydrawing import Color
def add_replies_to_annotation():
with Annotator("./sample.pdf") as annotator:
area = AreaAnnotation()
area.box = Rectangle(100, 100, 100, 100)
area.background_color = Color.yellow.to_argb()
area.page_number = 0
area.message = "Please review this section"
# Attach a threaded discussion to the annotation
first_reply = Reply()
first_reply.comment = "Good catch, I'll take a look."
first_reply.user = User(name="Tom", role=Role.EDITOR)
second_reply = Reply()
second_reply.comment = "Agreed, looks resolved now."
second_reply.user = User(name="Jack", role=Role.VIEWER)
area.replies = [first_reply, second_reply]
annotator.add(area)
annotator.save("./output.pdf")
if __name__ == "__main__":
add_replies_to_annotation()
