python 批量将PPT导出成图片集的案例

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

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

'''该工具函数的功能：批量将PPT导出成图片'''import comtypes.clientimport osimport win32comimport win32com.client# base pathBASH_PATH = ’C:webpythontoolformatPPTtaobaoppts’# render jpgRENDER_BASE_PATH = ’C:webpythontoolformatPPTtaobaorender’# 初始化PPTdef init_powerpoint(): powerpoint = win32com.client.Dispatch(’PowerPoint.Application’) #comtypes.client.CreateObject('Powerpoint.Application') powerpoint.Visible = 1 return powerpoint# PPT TO PDF def ppt_to_pdf_or_jpg(powerpoint, inputFileName, outputFileName, formatType = 32): if outputFileName[-3:] != ’pdf’: outputFileName = outputFileName[0:-4] + '.pdf' deck = powerpoint.Presentations.Open(inputFileName) #deck.SaveAs(outputFileName, formatType) # formatType = 32 for ppt to pdf deck.SaveAs(inputFileName.rsplit(’.’)[0] + ’.jpg’, 17) deck.Close()# save file as a folderdef convert_files_in_folder(powerpoint, folder): files = os.listdir(folder) pptfiles = [f for f in files if f.endswith(('.ppt', '.pptx'))] print(pptfiles) for pptfile in pptfiles: fullpath = os.path.join(cwd, pptfile) ppt_to_pdf_or_jpg(powerpoint, fullpath, fullpath)# delete more ppt and select 20 def delete_more_ppt(folder):files = os.listdir(folder)allNum = len(files)endPoint = 0if(allNum <= 20):returnelse:endPoint = allNum - 20for f in files[0:endPoint]:if(os.path.isfile(folder+f)):os.unlink(folder+f)# exec picture compositedef execPictureComposite():os.system(’python componsite_jpg_taobao.py’)pass# delete render jpgsdef deleteRenderJpg(): jpgs = os.listdir(RENDER_BASE_PATH) for jpg in jpgs: os.unlink(RENDER_BASE_PATH+jpg)if __name__ == '__main__': cwd = BASH_PATH delete_more_ppt(cwd) deleteRenderJpg() powerpoint = init_powerpoint() convert_files_in_folder(powerpoint, cwd) powerpoint.Quit() execPictureComposite()

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=’这里是标题’#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’);

以上为个人经验，希望能给大家一个参考，也希望大家多多支持好吧啦网。如有错误或未考虑完全的地方，望不吝赐教。
