‘Tkinter’ is a popular Python library for creating simple GUI applications. This solution will use Tkinter's ‘Canvas’ widget to draw shapes, freehand strokes, and save the drawing to a file. Code: # Solution 1: Basic Drawing App Using Tkinter import tkinter as tk # Import the Tkinter ...
1.调用ImageFilter类 from PIL import ImageFilter 2. ImageFilter类预定义图像过滤方法 from PIL import Image from PIL import ImageFilter square = Image.open("C:\\Users\\XXQ20180829\\Desktop\\2.jpg") square1 = square.filter(ImageFilter.CONTOUR) #选择轮廓效果 square1.save("C:\\Users\\XXQ20180...
from PIL import Image, ImageFilter # 打开一个jpg图像文件,注意是当前路径: im = Image.open('test.jpg') # 应用模糊滤镜: im2 = im.filter(ImageFilter.GaussianBlur) im2.save('blur.jpg', 'jpeg') 1. 2. 3. 4. 5. 6. 7. 效果如下: (3)生成字母验证码 from PIL import Image, ImageDraw,...
mode : RGB(true color image),此外还有,L(luminance),CMTK(pre-press image)。 现在,我们可以使用一些在 Image 类中定义的方法来操作已读取的图像实例。比如,显示最新载入的图像: 1>>>im.show() 2>>> 输出原图: 3. 函数概貌。 3.1 Reading and Writing Images : open( infilename ) , save( outfile...
