import groupdocs.comparison as gc
def save_page_callback(page_number: int, stream):
with open(f"page-{page_number}.png", "wb") as f:
f.write(stream.read())
with gc.Comparer("source.docx") as comparer:
preview_options = gc.PreviewOptions(save_page_callback)
preview_options.preview_format = gc.PreviewFormats.PNG
preview_options.page_numbers = [1, 2, 3]
comparer.get_pages(preview_options)
