Question

我需要将图像添加到pptx幻灯片中，并希望将其放置在幻灯片的中心，而无需手动计算尺寸和对齐方式，

我发现了一个关于使用文字执行此操作的问题： question about center aligning text

关于使用文本执行此操作的文档： documentation about center aligning text

但无法为图像找到方法，

想法？

Answer 1

It's not going to work the same way as text; there's no center justification or alignment property on an image. You'll need to use a formula.

image.left = (prs.slide_width - image.width) / 2

这对我有用：

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


# instantiate presentation
prs = Presentation()

# change slide sizes to Widescreen
slide_size = (16, 9)
prs.slide_width, prs.slide_height = Inches(slide_size[0]), Inches(slide_size[1])

# convert pixels to inches
def px_to_inches(path):
    
    im = Image.open(path)
    width = im.width / im.info['dpi'][0]
    height = im.height / im.info['dpi'][1]
    
    return (width, height)

img = px_to_inches('logo.png')

# insert logo image
left = Inches(slide_size[0] - img[0]) / 2
top = Inches(slide_size[1] - img[1]) / 2
pic = slide.shapes.add_picture('logo.png', left, top)

python pptx将图像对齐到幻灯片的中心
