How to pass PIL image to Add_Picture in python-pptx

问题

I'm trying to get the image from clipboard and I want to add that image in python-pptx . I don't want to save the image in the Disk. I have tried this:

from pptx import Presentation
from PIL import ImageGrab,Image
from pptx.util import Inches
im = ImageGrab.grabclipboard()
prs = Presentation()
title_slide_layout = prs.slide_layouts[0]
slide = prs.slides.add_slide(title_slide_layout)
left = top = Inches(1)
pic = slide.shapes.add_picture(im, left, top)
prs.save('PPT.pptx')

But Getting this error

File "C:\Python27\lib\site-packages\PIL\Image.py", line 627, in __getattr__
    raise AttributeError(name)
AttributeError: read

What is wrong with this?

回答1:

The image needs to be in the form of a stream (i.e. logical file) object. So you need to "save" it to a memory file first, probably StringIO is what you're looking for.

This other question provides some of the details.

This worked for me

import io
import PIL
from pptx import Presentation
from pptx.util import Inches

# already have a PIL.Image as image
prs = Presentation()
blank_slide = prs.slide_layout[6]
left = top = Inches(0)

# I had this part in a loop so that I could put one generated image per slide
image: PIL.Image = MyFunctionToGetImage()
slide = prs.slides.add_slide(blank_slide)
with io.BytesIO() as output:
    image.save(output, format="GIF")
    pic = slides.add_slide(output, left, top)
# end loop
prs.save("my.pptx")
