We now have a blank image (like a canvass) in which we can now draw our circle. 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 above code fence produces the following output: Lastly, the most important thing is that you also have to use the waitKey() method of the OpenCV and pass the value 0 to it. If you don’t add this line of code, it will render the image with a circle on a separate tab, and ...

Now, to draw a circle on the image, we simply need to call thecirclefunction of thecv2module. Note that this function will not return a new image but rather draw the circle on the image we will pass as input. But, as long as we don’t save this edited image, the circle will be...
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...
