Python 插入第五张幻灯片中的图片

Question

我有一个包含图像的文件夹，我将其插入到我正在生成的 PPTX 文件中。下面的代码从第一张幻灯片开始插入图像，但我希望它从第五张幻灯片开始插入图像。我无法寻找解决方案请帮忙。提前致谢。

def Generate_PPT(avg_plots):
    prs = Presentation() 
    blank_slide_layout = prs.slide_layouts[6] 

    for imagePath in (avg_plots):
        if (avg_plots.index(imagePath)) % 2 == 0:
            slide = prs.slides.add_slide(blank_slide_layout)
            left = top = Inches(1)
            pic = slide.shapes.add_picture(imagePath, left, top) 

    prs.save(os.path.join(root,folder1,'PPT_plots.pptx'))

Answer 1

请参考以下内容link： https://python-pptx.readthedocs.io/en/latest/api/slides.html

要获取第五张幻灯片，请使用如下所示的 get 方法。

slide=prs.slides.get(4)

如果你想生成一个新的ppt并添加第5张幻灯片的图片，请参考下面的代码。

            prs = Presentation()
            blank_slide_layout = prs.slide_layouts[6]
            for x in range(5):
                slide = prs.slides.add_slide(blank_slide_layout) ## 5 slides got created
            print(prs.slides.index(slide)) # this will print 4, index for the last slide
            slide = prs.slides.get(4) #use this to access slide 5                                             
            # do the changes to the slide (add image) 
            prs.save(os.path.join('PPT_plots.pptx'))

解决此问题的一种方法是在进入 "image insertion" 循环之前创建前四张幻灯片：

def Generate_PPT(avg_plots):
    prs = Presentation() 
    blank_slide_layout = prs.slide_layouts[6] 

    # --- add four blank slides such that first image appears on fifth slide ---
    for _ in range(4):
        prs.slides.add_slide(blank_slide_layout)

    # --- then image insertion proceeds from fifth slide onward ---
    for imagePath in (avg_plots):
        if (avg_plots.index(imagePath)) % 2 == 0:
            slide = prs.slides.add_slide(blank_slide_layout)
            left = top = Inches(1)
            pic = slide.shapes.add_picture(imagePath, left, top) 

    prs.save(os.path.join(root, folder1, 'PPT_plots.pptx'))
