简单一个例子: 效果: 代码: import pygame from pygame.locals import * def DrawCircle(screen): BLUE = (0, 0, 255) position = 300,250 radius = 100 width = 10 pygame.draw.circle( screen, BLUE, position, radius, width ) def
bounding_rectangle参数可以是pygame.Rect对象或四个整数的元组。请注意,您不像对pygame.draw.circle()函数那样为椭圆指定中心点。 pygame.draw.rect(surface, color, rectangle_tuple, width) - 此函数绘制矩形。rectangle_tuple可以是四个整数的元组(用于左上角的 XY 坐标,以及宽度和高度),也可以传递pygame.Rect对象。
As first input, thecirclefunction receives the image on which we want to draw the circle. As second, it receives atuplewith the x and y coordinates of the center of the circle. As third argument, we need to pass the radius of the circle and as fourth, we need to specify another tupl...

Next, we use the cv2.circle() function to create our circle on this white blank image. The first parameter that we must feed into the cv2.circle() function is the image we want to draw it on. We will be using what we created with numpy, whiteblankimage. This provides a perfect clea...
就像我们使用pygame.draw.circle函数创建圆形一样,我们可以使用pygame.draw.polygon来绘制任何类型的多边形。对多边形函数的调用以点列表的形式作为参数,并将使用这些点绘制多边形形状。我们可以使用类似的方式使用特定的称谓绘制不同的几何形状。 在接下来的部分中,我们将学习使用pygame模块初始化显示屏和处理键盘和鼠标事件...
因此,mapSurf 变量中的 Surface 对象只有在 mapNeedsRedraw 变量被设置为 True 时才会通过调用 drawMap() 函数进行更新。 在第225 行绘制地图后,mapNeedsRedraw 变量被设置为 False。如果想要看到程序在游戏循环的每次迭代中绘制而变慢,可以注释掉第 226 行并重新运行程序。你会注意到移动摄像头会明显变慢。 代码...
The OpenCV library provides you with various methods out of the box and makes our life much easier when it comes to dealing with recognizing, processing, managing, and editing images. In this article, we will see how to draw a circle on an image with the help of the OpenCV library’s ...

houghcircles函数 python python circle函数用法 源代码+代码解释+小结 要用这个程序,首先需要下载一个叫swampy的包(package),也就是一个文件夹或者说是一套模块,其中包含了很多的函数。关于package的安装只需提一点,由于模块不大,最好直接安装默认的路径(也就是直接打开shell或者dos提示符的工作路径)里,确保只有一个...
