python刑事案卷图片转pdf

分两步，第一步是转图片，第二步是合并。

 # -*- coding: utf-8 -*-
import glob,os
from PIL import Imagedef convert_to_pdf(path):# 打开图片文件img = Image.open(path)# 将图片转换为 PDF，并保存到同名文件pdf_path = os.path.splitext(path)[0] + ".pdf"img.save(pdf_path, "PDF", resolution=300.0)if __name__ == "__main__":image_dir = os.getcwd()print(image_dir)for dirs in os.listdir(image_dir):if os.path.isdir(dirs):print(dirs)newdir=image_dir+"\\"+dirsprint(newdir)for sondirs in os.listdir(newdir):if sondirs[-3:]=="jpg":sonpath=newdir+"\\"+sondirsprint(sonpath)    convert_to_pdf(sonpath)

合并成pdf

 # -*- coding: utf-8 -*-import glob,os
from PyPDF2 import PdfFileWriter, PdfFileReader,PdfMergerdef merge2(output_path,input_paths):pdf_merge = PdfMerger()for path in input_paths:pdf_merge.append(path)with open(output_path,'wb') as fileObj:pdf_merge.write(fileObj)if __name__ == '__main__':path=os.getcwd()print(path)for dirs in os.listdir(path):if os.path.isdir(dirs):print(dirs)paths = glob.glob(dirs+"/*.pdf")print(paths)merge2(dirs+".pdf",paths)
