python 批量将PPT导出成图片集的案例
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
""" 该工具函数的功能:批量将PPT导出成图片 """ import comtypes.client import os import win32com import win32com.client # base path BASH_PATH = 'C:\\web\\python\\tool\\formatPPTtaobao\\ppts\\' # render jpg RENDER_BASE_PATH = 'C:\\web\\python\\tool\\formatPPTtaobao\\render\\' # 初始化PPT def 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 folder def 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 = 0 if(allNum <= 20): return else: endPoint = allNum - 20 for f in files[0:endPoint]: if(os.path.isfile(folder+f)): os.unlink(folder+f) # exec picture composite def execPictureComposite(): os.system('python componsite_jpg_taobao.py') pass # delete render jpgs def 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 Presentation from pptx.util import Inches,Pt ppt=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.placeholders body_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.title title_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=True new_paragraph.font.italic=True new_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我们。如有错误或未考虑完全的地方,望不吝赐教。
