Examples

Shows how to extract images from a document, and save them to the local file system as individual files.

doc = aw.Document(MY_DIR + 'Images.docx')
# Get the collection of shapes from the document,
# and save the image data of every shape with an image as a file to the local file system.
shapes = doc.get_child_nodes(aw.NodeType.SHAPE, True)
self.assertEqual(9, len([s for s in shapes if s.as_shape().has_image]))
image_index = 0
for shape in shapes:
    shape = shape.as_shape()
    if shape.has_image:
        # The image data of shapes may contain images of many possible image formats.
        # We can determine a file extension for each image automatically, based on its format.
        image_file_name = f'File.extract_images.{image_index}{aw.FileFormatUtil.image_type_to_extension(shape.image_data.image_type)}'
        shape.image_data.save(ARTIFACTS_DIR + image_file_name)
        image_index += 1
