python pptx导出img(png，jpeg) [英] python pptx export img (png, jpeg)

问题描述

我已经用Python开发了一个小的代码来生成PPTX.但我也想在这张幻灯片的png或jpeg中生成图片.

I have developed a small code in Python in order to generate PPTX. But I would like also to generate a picture in png or jpeg of this slide.

from pptx import Presentation
from pptx.util import Inches

img_path = 'monty-truth.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)

left = Inches(5)
height = Inches(5.5)
pic = slide.shapes.add_picture(img_path, left, top, height=height)

prs.save('test.pptx')

是否可以将PPTX文件(仅包括一张幻灯片)转换为PNG或JPEG图片?

Is there a way to transform a PPTX file (including just one slide) into a PNG or JPEG picture ?

推荐答案

您可以使用以下代码:

Application = win32com.client.Dispatch("PowerPoint.Application")
Presentation = Application.Presentations.Open(r"your_path")
Presentation.Slides[0].Export(r"the_new_path-file.jpg", "JPG")
Application.Quit()
Presentation =  None
Application = None

在此行中，您可以更改要导出的幻灯片的编号(例如，下面的幻灯片编号为6):

With this line, you can change the number of the slide you want to export (for example below, for slide number 6) :

Presentation.Slides[5].Export(r"the_new_path-file.jpg", "JPG")
