I would like to use imagemagick Wand package to convert all pages of a pdf file into a single image file. I am having the following trouble though (see comments below which highlight problem)
import tempfile
from wand.image import Image
with file('my_pdf_with_5_pages.png') as f:
image = Image(file=f, format='png')
save_using_filename(image)
save_using_file(image)
def save_using_filename(image):
with tempfile.NamedTemporaryFile() as temp:
# this saves all pages, but a file for each page (so 3 files)
image.save(filename=temp.name)
def save_using_file(image):
with tempfile.NamedTemporaryFile() as temp:
# this only saves the first page as an image
image.save(file=temp)
My end goal it to be able to specify which pages are to be converted to one continual image. This is possible from the command line with a bit of
convert -append input.pdf[0-4]
but I am trying to work with python.
I see we can get slices by doing this:
[x for x in w.sequence[0:1]] # get page 1 and 2
now its a question of how to join these pages together.
My solution:
from wand.image import Image
diag='yourpdf.pdf'
with(Image(filename=diag,resolution=200)) as source:
images=source.sequence
pages=len(images)
for i in range(pages):
Image(images[i]).save(filename=str(i)+'.png')
It works, and compared to other answers, it appears more flexible to some multi-page pdf files with variable size in different pages.
