Python使用pptx实现复制页面到其他PPT中

时间:2023-02-03 虚坏叔叔人气:0

一、原理

如题，我有一个模板课件.pptx：

其内容：

我想复制模板中间的某一页多次，比如复制第1页，然后复制3次，

prs = Presentation(r"D:\自动化\课件.pptx")
for i in range(0,3):
    copied_slide = duplicate_slide(prs, 0)

次数是根据我的需求指定的，使用python pptx模块复制，

def duplicate_slide(pres,index):
    template = pres.slides[index]
    blank_slide_layout = pres.slide_layouts[index]
    copied_slide = pres.slides.add_slide(blank_slide_layout)
    for shp in template.shapes:
        el = shp.element
        newel = copy.deepcopy(el)
        copied_slide.shapes._spTree.insert_element_before(newel, 'p:extLst')
    for _, value in six.iteritems(template.part.rels):
        # Make sure we don't copy a notesSlide relation as that won't exist
        if "notesSlide" not in value.reltype:
            copied_slide.part.rels.add_relationship(value.reltype,
            value._target,
            value.rId)
    return copied_slide

然后保存成另一个pptx文件

path = r'D:\自动化\result.pptx'
prs.save(path)

复制后的ppt内容

二、所有代码

import copy,six
from pptx import Presentation


def duplicate_slide(pres,index):
    template = pres.slides[index]
    blank_slide_layout = pres.slide_layouts[index]
    copied_slide = pres.slides.add_slide(blank_slide_layout)
    for shp in template.shapes:
        el = shp.element
        newel = copy.deepcopy(el)
        copied_slide.shapes._spTree.insert_element_before(newel, 'p:extLst')
    for _, value in six.iteritems(template.part.rels):
        # Make sure we don't copy a notesSlide relation as that won't exist
        if "notesSlide" not in value.reltype:
            copied_slide.part.rels.add_relationship(value.reltype,
            value._target,
            value.rId)
    return copied_slide

prs = Presentation(r"D:\自动化\课件.pptx")
for i in range(0,3):
    copied_slide = duplicate_slide(prs, 0)
path = r'D:\自动化\result.pptx'
prs.save(path)
