Extract annotations from document page Leave feedback
On this page
get_annotations(page_index) returns the annotations of one page (or slide) only. Page indexes start at 0.
from groupdocs.parser import Parser
with Parser("./reviewed.pdf") as parser:
# Extract annotations from the first page (page indexes start at 0)
annotations = parser.get_annotations(0)
if annotations is None:
print("Annotation extraction isn't supported for this format")
else:
print("Page 1: %d annotations" % len(annotations))
for annotation in annotations:
print(" [%s] %s" % (annotation.annotation_type, annotation.value))
The following sample file is used in this example: reviewed.pdf
Expected behavior: For the sample, prints:
Page 1: 2 annotations
[Text] Approve the hero crop before the print run.

Use get_document_info().page_count to walk every page:
from groupdocs.parser import Parser
with Parser("./reviewed.pdf") as parser:
if not parser.features.annotations:
print("Annotation extraction isn't supported for this format")
else:
page_count = parser.get_document_info().page_count
for page_index in range(page_count):
annotations = parser.get_annotations(page_index)
print("Page %d of %d: %d annotations" % (page_index + 1, page_count, len(annotations)))
for annotation in annotations:
print(" %s: %s" % (annotation.author_name or "(no author)", annotation.value))
The following sample file is used in this example: reviewed.pdf
Expected behavior: For the two-page sample, prints:
Page 1 of 2: 2 annotations
Tomas Reyes: Approve the hero crop before the print run.
(no author): Aurora Visuals portfolio
Page 2 of 2: 0 annotations
- A page without annotations gives an empty list, not
None. - Every
AnnotationItemalso carries its ownpage_index, soget_annotations()followed by grouping onpage_indexgives the same result in one call.
