这篇文章主要介绍了Python实现图片指定位置加图片水印,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值，需要的朋友们下面随着小编来一起学习学习吧
（一）功能实现效果：
标记预加水印的位置：
（二）Python代码：
# -*l- coding:utf-8 * import os, io, sys, re, time, json from pandas import array import matplotlib.backends.backend_tkagg import matplotlib matplotlib.use('TkAgg') import matplotlib.pyplot as plt #from matplotlib.pyplot import imshow, ginput from PIL import Image, ImageEnhance, ImageFilter import wx import numpy as np import random class DirDialog(wx.Frame): def __init__(self): """Constructor""" wx.Frame.__init__(self, None, -1, u"文件夹选择对话框") b = wx.Button(self, -1, u"请选择图片") self.Bind(wx.EVT_BUTTON, self.OnButton, b) def OnButton(self, event): # file_wildcard = "Paint files(*.paint)|*.paint|All files(*.*)|*.*" dlg = wx.FileDialog(self, u"选择文件夹", wx.DD_DEFAULT_STYLE) if dlg.ShowModal() == wx.ID_OK: jpegname = dlg.GetPath() # 文件夹路径 print(jpegname) np.savez('dir.npz', k_a=str(jpegname)) dlg.Destroy() def sealmark(img_seal, img_new): try: data_a = np.load('dir.npz')#保存地址数据 img_source = str(data_a['k_a']) # 原图片的地址 im1 = Image.open(img_source) plt.imshow(im1) xy = plt.ginput(1) xo = xy[0][0] yo = xy[0][1] ks = im1.size[1] * 0.000478 wm = Image.open(img_seal) wm = wm.resize((int(wm.width * ks), int(wm.height * ks))) # wm.with * k=280 * ks layer = Image.new('RGBA', im1.size, (0, 0, 0, 0)) layer.paste(wm, (int(xo), int(yo))) newIm = Image.composite(layer, im1, layer) newIm.save(img_new) print(img_seal) except Exception as e: print(">>>>>>>>>>> sealMark EXCEPTION: " + str(e)) return False else: return True if __name__ == '__main__': frame = wx.App() app = DirDialog() app.Show() frame.MainLoop() sealmark("水印水印" + str(random.randrange(10)) + ".png", "after_seal.jpg") #random.randrange(10)：随机在水印库中挑选一张PNG水印图片
（三）Python打包成exe程序：
在终端里输入pyinstaller -F -w add_seal.pyC:UsersAdministratorDesktopseal>pyinstaller -F -w add_seal.py（1）出现以下的打包成功信息：
