导读
需要使用python做一个将很多个不规则PPT导出成用文件夹归纳好的图片集,所以就需要使用comtypes调用本机电脑上的ppt软件,批量打开另存为多张图片
采坑
公司电脑使用comtypes完美导出图片,系统win10
回家后使用自己的电脑就报错,系统也是win10,最后没办法放弃comtypes采用win32com,最终成功
源代码

补充:用python处理ppt中的文字
我就废话不多说了,大家还是直接看代码吧~
from pptx import Presentationfrom pptx.util import Inches,Ptppt=Presentation()#在ppt中加入一个幻灯片slide=ppt.slides.add_slide(ppt.slide_layouts[1])#第一种body_shape=slide.shapes.placeholdersbody_shape[0].text='这是占位符[0]'body_shape[1].text='这是占位符[1]'#第二种title_shape=slide.shapes.titletitle_shape.text='这里是'#取出本页第二个文本框subtitle=slide.shapes.placeholders[1]#在第二个文本框里写入汉字subtitle.text='这里是文本框'#在文本框里添加一个段落new_paragraph=body_shape[1].text_frame.add_paragraph()new_paragraph.text='新段落'new_paragraph.font.bold=Truenew_paragraph.font.italic=Truenew_paragraph.font.size=Pt(15)new_paragraph.font.underline=True#添加文本框left=Inches(2)top=Inches(2)width=Inches(3)height=Inches(3)textbox=slide.shapes.add_textbox(left,top,width.height)textbox.text="这是新文本框"#在文本框里添加新段落new_par=textbox.text_frame.add_paragraph()new_par.text='这是文本框里的第二段'ppt.save('test.pptx');
