Answer 1

From a previous answer, try creating an empty image with a background color, then composite over.

from wand.image import Image
from wand.color import Color

with Image(filename="sample.pdf", resolution=300) as img:
  with Image(width=img.width, height=img.height, background=Color("white")) as bg:
    bg.composite(img,0,0)
    bg.save(filename="image.png")
