闲话少叙: 效果: 可运行代码: import pygame from pygame.locals import * def DrawRect(screen): mycolcor = (0, 0, 255) x = 300 y = 250 position = ( x, y, 100, 100 ) width = 0 pygame.draw.rect( screen…

接下来,我们可以使用Rectangle对象来画一个矩形。需要指定矩形的左下角坐标、宽度和高度: rectangle=plt.Rectangle((0.2,0.2),0.6,0.5,edgecolor='black')ax.add_patch(rectangle) 1. 2. 4. 填充颜色 我们可以使用set_facecolor方法来填充矩形的颜色。可以使用颜色名称或者RGB值: rectangle.set_facecolor('red') ...
1 首先你需要安装上pil，不过在python3安装不上或者2的64位也安装不了python3可以安装pip install pillow 2 首先我们用这段打开一张图片，跟你的程序不在一个文件夹的话要长地址img=Image.open("1.jpg") #打开图片1.jpg 3 a=ImageDraw.ImageDraw(img)由于拿来表示对象的太长，可以用这个来缩减一下，下次用...
