how to download or save a picture from a powerpoint ppt with python pptx

问题

I am working on powerpoints using python.pptx, where I am struggling to save certain picture from a slide to local system.Can anyone suggest me how to do it?

Until now : I am able to print the shape, But dont know how to save the picture as we do with presentation using prs.save.

prs =Presentation('mypath/myPowerpoint.pptx')
slide2 = prs.slides[1]       #i want to save picture in slide 2
pic = slide2.shapes[4]       # i have check shape 5 is the picture
print(pic.name)              # i am able to print the picture name
pic.save('Mypic.jpg')        #------ this didn't work --------

Thanks in advance.

An image depicted in a Picture shape can be accessed using its image property. The Image object provides access to detailed properties of the image, including the bytes of the image file itself.

http://python-pptx.readthedocs.io/en/latest/api/image.html#pptx.parts.image.Image

So, for example:

with open('mypic.jpg', 'wb') as f:
    f.write(pic.image.blob)
