python pillow库完成数据批量盖章 打包成相应的exe  

盖章前                                                                        改章后

代码如下

#coding = utf-8

import  os

import  shutil

from  PIL  import  Image

png=[]

imagewater =Image.open("awt.gif")

for  root,dirs,files  in os.walk(os.getcwd()):

    for file  in files:

        fe=os.path.join(root,file)

        if fe.endswith("png"):

            png.append(fe)

if not os.path.exists("png"):

    os.mkdir("png")

else:

    print("存在文件夹")

newpath=os.path.join(os.getcwd(),"png")

#读取文件

for  i  in  png:

    pngobj=Image.open(i)

    #将图片转换为rgba值

    rgbawater=imagewater.convert("RGBA")

    rgbapng=pngobj.convert("RGBA")

    #尺寸赋值

    imagewater_x,imagewater_y=rgbawater.size

    pngobj_x,pngobj_y=rgbapng.size

    #缩放图片尺

    scale=7

    watermark_scale = max(pngobj_x / (scale * imagewater_x), pngobj_y / (scale * imagewater_y))

    new_size = (int(imagewater_x * watermark_scale), int(imagewater_y * watermark_scale))

    rgbawater = rgbawater.resize(new_size, resample=Image.ANTIALIAS) 

    #印章与图片融合

    rgbapng.paste(rgbawater,(pngobj_x-imagewater_x-1550,pngobj_y-imagewater_y+1300))

    out=Image.composite(rgbapng,pngobj,rgbapng)

    b=i.split(".png")[0]+"new"+".png" 

    out.save(b)

    print("*"*30)

    print("%s 完成盖章扫描 "%(i))

    if  "new"  in  b:

        shutil.move(b,newpath)

for root ,dirs, files  in  os.walk(newpath):

    for file in files:

        oldFnme=os.path.join(root,file)

        g=file.split("new")[0]+".png"

        newFnme=os.path.join(root,g)

        os.rename(oldFnme,newFnme)

        print("%s 完成创建"%(g))
