Python-pptx slide.shapes.add_picture() 无法识别图像文件 [英] Python-pptx slide.shapes.add_picture() not recognizing image files

问题描述

我正在尝试使用 pptx 将图像添加到 PowerPoint 幻灯片.

I am trying to add images to a PowerPoint slide using pptx.

img_path = 'test.png'

prs = Presentation()
blank_slide_layout = prs.slide_layouts[6]
slide = prs.slides.add_slide(blank_slide_layout)

left = top = Inches(1)
pic = slide.shapes.add_picture(img_path, left, top)

每次我运行这个(我尝试了几个不同的图像，一些是由 matplotlib 生成的，一些是下载的)我从 .add_picture() 收到以下错误:

Every time I run this (I have tried with several different images, some generated by matplotlib and some downloaded) I receive the following error from the .add_picture():

Continuum\Anaconda\lib\site-packages\pptx\parts\image.pyc in _size(self)
    158         image_stream = StringIO(self._blob)
--> 159         width_px, height_px = PIL_Image.open(image_stream).size
    160         image_stream.close()
    161         return width_px, height_px

Continuum\Anaconda\lib\site-packages\PIL\Image.pyc in open(fp, mode)
   1978     :param size: A 2-tuple, containing (width, height) in pixels.
   1979     :param color: What color to use for the image.  Default is black.
-> 1980        If given, this should be a single integer or floating point value
   1981        for single-band modes, and a tuple for multi-band modes (one value
   1982        per band).  When creating RGB images, you can also use color

IOError: cannot identify image file

我该怎么做才能解决这个问题?

What can I do to fix this problem?

推荐答案

这看起来像是与 PIL/Pillow 库相关的问题.您能否详细介绍一下您工作的环境以及您使用的 PIL 版本?我知道同时安装 PIL 和 Pillow 时存在一些潜在问题.如果您可以控制自己的 Python 环境，我会先卸载两者，然后只安装最新版本的 Pillow.

This looks like a problem related to the PIL/Pillow library. Can you say more about the environment you're working in and what PIL version you're using? I know there are some potential problems when having both PIL and Pillow installed. If you have control over your Python environment I'd start by uninstalling both and then installing just the most recent version of Pillow.
