import groupdocs.watermark as gw
import groupdocs.watermark.watermarks as gww
import groupdocs.watermark.common as gwc
with gw.Watermarker("document.pdf") as watermarker:
text_watermark = gww.TextWatermark("Protected image", gww.Font("Arial", 8.0))
text_watermark.horizontal_alignment = gwc.HorizontalAlignment.CENTER
text_watermark.vertical_alignment = gwc.VerticalAlignment.CENTER
text_watermark.rotate_angle = 45
text_watermark.sizing_type = gww.SizingType.SCALE_TO_PARENT_DIMENSIONS
text_watermark.scale_factor = 1.0
with gww.ImageWatermark("protect.jpg") as image_watermark:
image_watermark.horizontal_alignment = gwc.HorizontalAlignment.CENTER
image_watermark.vertical_alignment = gwc.VerticalAlignment.CENTER
image_watermark.rotate_angle = -45
image_watermark.sizing_type = gww.SizingType.SCALE_TO_PARENT_DIMENSIONS
image_watermark.scale_factor = 1.0
images = watermarker.get_images()
for i in range(images.count):
if images[i].width > 100 and images[i].height > 100:
if i % 2 == 0:
images[i].add(text_watermark)
else:
images[i].add(image_watermark)
watermarker.save("document.pdf")
